Why Whole House Fans Are Great For Summer

The summer season is upon us. And while thoughts commonly wander towards images of the beach, brand new summer wear, or long trips on the open road, for more forward-thinking homeowners, other burning questions linger:

“It’s crazy warm out here– where’d all this sun come from?”

“How much is my AC bill going to be this summer?”

“Who thought climate change isn’t a real thing?”

If you live in Sacramento, you know how hot it can be inside in mid-summer. A whole house fan installation with a bunch of ceiling fans all around your home can really make a difference.

If you live in Sacramento, you know how hot it can be inside in mid-summer. A whole house fan installation with a bunch of ceiling fans all around your home can really make a difference.

If you have air-conditioning installed at home, that’s great. What’s not so great is the look on your face when you start seeing your energy bills.

This is where a whole house fan in Sacramento might come in handy.

Summers in Sacramento can be relentless, especially so in months like July, where temperatures can push towards the mid- and high-90’s. Installing a whole house fan in your home can make the scorching summer weather a lot more bearable.

Commonly set up in your attic, a whole house fan draws all the warm, stale, humid air within your home and pulls in fresher air from the outside through your windows and doors.

What you get is a steady, refreshing indoor breeze moving through your home.

Whole House Fans Save You Money

One of the reasons why whole house fans have been steadily gaining popularity again these days is that they significantly cut down on energy costs.

Switching off the air conditioning towards the evening and letting your whole house fan work its magic can bring the interior temperature of your home down by as much as 20 degrees Fahrenheit.

Whether as a standalone cooling option for your home or working in tandem with your existing AC installation, lower energy bills mean you save more money– and all those savings from heating and cooling costs add up over a year.

You Get Cleaner Air Inside The Home with a Whole House Fan

As stagnant air gets sucked out of your home, allowing for fresher air to come inside, you’re also reducing airborne hazards this way.

Nasty stuff like radon, formaldehyde, carbon monoxide, as well as odors from cooking and pets also get vented out, leaving you with a cleaner quality of air inside, so long as your whole house fan is running.

Whole House Fans Are Eco-Friendly

Usually going green on a home improvement project means added costs to your bottom line.

But the installation of a whole house fan costs far less than a brand new AC system. And when you consider the long-term benefits to your family’s health and well-being, as well as your positive contribution to the environment, all the good you’ve done far outweighs any cost investment you’ve incurred.

All Year Air & Heating highly recommends the QuietCool brand of whole house fans.

5 Signs Your AC Needs Replacement

Imagine a warm summer day in sunny Sacramento.

Now imagine you are comfortably tucked into your bed ready to take an afternoon nap. Suddenly, you hear a loud creaking noise from your AC, and you can’t figure out why it is making that noise. This may be a sign that your air conditioning system needs to be replaced.

What are the signs you have to watch out for when it is time to replace your AC? Here are 5 common signs that you need to replace your air conditioning:

1. Water leaks and excessive moisture

It is normal to find some damp spots around your AC. However, excessive moisture can point to greater damage.

Your AC should not be accumulating puddles of water around. Water puddles can be a sign of broken tubes or leaking pipes, which can potentially cause harm to your family or your property.

Leaking coolants are bad for you and your family’s health. It is best to make sure that these are addressed immediately. If the damage in the hardware of your AC is extensive, it may be a wiser option to let go of it.

2. Warm air

There is nothing more annoying than an AC that blows out warm and humid air. A lot of factors may be the cause for this, such as Freon level running out, or even broken compressor.

The best course of action, in this case, is to call a professional. They can give a quotation on how much you are going to spend on the repair. If the price comes to a whopping amount, it is better to get a replacement.

3. Bad odor

Ideally, the air that comes out of your AC should not smell. In case it does, this may be due to burnt wire insulation or mold infestation.

Call an expert right away if your AC starts emitting a pungent smell. Do not attempt to cover the smell by the mere use of deodorizers, as the smell may be a sign of a bigger problem.

4. Uncontrolled humidity

Your AC has two functions. First is to blow out cool air, and second is to regulate the humidity of your house.

It should be able to keep the humidity of a room at a comfortable level. Even considering that Sacramento does not exactly have humid weather, this is still a little need to control the humidity in the air.

If your AC is not performing this job well, this might be a sign it needs replacement.

5. Doubled electricity bills

If you notice that your electricity bill suddenly spikes up, and you have not changed your way of consumption, this should alarm you that something in your house is causing the increase.

More often than not, this may be caused by broken items that consume more energy such as heaters, freezers, and most especially your AC.

Call a professional and have them checked out. Replacing a broken AC might save you more money in the long run.

What are the advantages of a whole house fan?

A whole house fan is often an afterthought for new homeowners who have experienced the
worst summer of their lives. Whole house fans have many benefits; it does not only keep the
house well ventilated, but it also helps maintain the temperature of the house.
We are listing the top benefits of installing a whole house fan in your home.

Whether you are heating or cooling your entire house, having a whole house fan practically
helps with both. When your heater is on, it consumes a considerable amount of energy to
arrives at your desired temperature and continually works as hard to make sure the
temperature is maintained. With a whole house fan installed, heaters can rest a little while the
whole house fan retains the heat of the house by working its system. The same goes for cooling
the home. The air conditioner eats up loads of power to reach the desired temperature as
quickly as possible. Switching to the whole house fan after the room has cooled down, will
benefit not only your electric bills but also your appliance. The wear and tear of your heater and
air conditioning units will be reduced as the whole house fan will do half the work for them.

A whole house fan also helps keep you family healthy. As much as families want to keep the
dust out by keeping windows closed, they are also trapping airborne particles and other
organisms that in the air. Using a whole house fan helps remove stale air in the house, making
sure that the air that flows inside the house is fresh and free from radicals that can threaten the
health of family members, especially kids. It also helps eliminate lousy odor or stuffy dense air
in the house. A well-ventilated home also helps keep mold from thriving. With a place well
ventilated, oxygen roams freely in the room. And oxygen is an active component in the
environment that is notorious for keeping mold from growing.

Operating your whole house fan cost 25 percent less than running your heater and air
conditioner. This means you can save on hundreds of dollars during the winter and the summer
seasons when your system works the most. And since it takes some of the work done by your
appliances, you also save on repair cost of your heater and air conditioning unit because these
are not overworked.

These are some of the most glaring benefits of a whole house fan, for more details you can
reach out to our staff so they can explain further why your home should have one.

Some households are intimidated by the thought of having a whole house fan because the
structure is complicated— with all the vents and tubing that it requires. Fret not; a whole
house fan is easy to install given the experience of All Year.

We, at All Year, ensure quality service delivered at the shortest time possible to bring you
comfort and improve your quality of life.

stand by for any questions or concerns that you might have.

4 Reasons Why an Annual Checkup of Your Air Conditioning Unit is Necessary: Notes from a Sacramento AC Repair Company

Your home air conditioning system can last you years with regular checkups and proper maintenance. But one of the most common questions asked by homeowners in the summer is, “how often do I need to have my air conditioning unit serviced?”

The short answer is: you should have your AC unit inspected, serviced, and cleaned at least once a year. And the best time to have it done is in the Spring, just before the summer season begins.

According to Sacramento AC repair company All Year Air & Heating, an annual servicing ensures that your AC units are operating at maximum efficiency, all primed to cool your house especially in the scorching months of summer when you need it the most.

Take good care of your AC unit, and it will take good care of you. Especially when you need it the most.

Take good care of your AC unit, and it will take good care of you. Especially when you need it the most.

Even if you don’t suspect any problems with your AC unit, annual maintenance is necessary. And here are four reasons why:

1. You know what they say about an ounce of prevention

Summer is a busy time for AC companies like All Year Air & Heating. And it’s not because of all the additional installations; it’s because of all the AC repairs.

It would seem that many Sacramento residents have decided to skip on their regular maintenance checks on their AC units, sometimes even foregoing annual checkups for years.

The result: their air conditioning breaks down unexpectedly just when they need it the most.

Having an annual tune-up of your cooling systems costs far less than having to call in the professionals later on for an emergency repair during the busiest time of the year.

2. A clean AC cools you better than a dirty AC

When you switch on your AC for the first time after months of being dormant, don’t you notice a musty smell coming out of it?

As you haven’t been using your air conditioning for months, dust and other debris have been building up within your unit. All this gunk can cause your cooling systems to operate inefficiently, as it has to work extra hard to power through all that build up to cool your home.

Your outside condenser unit is particularly subject to the elements. Coils frequently get coated with dust and gunk even if it is covered for the fall and winter.

When an AC technician comes in for routine maintenance, the outdoor coil is cleaned off with a high-pressure hose, or sometimes with chemicals for more persistent debris. They then go through other parts such as the blower fan and other components to make sure it’s clear of gunk and other buildup.

3. Regular maintenance keeps your AC purring like a kitten

Other parts of your air conditioning unit can also wear down over time. It’s not necessarily through excessive use; it’s really just part of the expected life cycle of your cooling system.

Regular AC checkups will normally inspect your fan belts and tighten electrical connections that might have loosened up somehow. They’ll also check for potential leaks (like the refrigerant, for example), and monitor other small critical components for any other problems.

Annual maintenance not only assesses your AC for overall health, but it also spots potential problems before they even happen.

Even if critical issues have been identified, they’d be easily taken care of way ahead of time before a major break down can cause you headaches during the summer season.

4. Routine checkups are for your peace of mind

>A home air-conditioning unit, as long as it is well-maintained and well-cared for, can serve you for years.
Regular AC tune-ups are all about giving you the confidence that your home can weather even the hottest summer days with ease.
With your air conditioning running smoothly, you can go through your day-to-day activities, make plans, and enjoy the summer months knowing your cooling system can handle the relentless heat just fine.

How Often Should You Tune Up Your Home Heating System?

Your heating system, just like most of your machines at home need a regular check-up and maintenance to make sure it runs smoothly. Especially during this wintertime, your house heating system and your furnace should be at their top shape to provide a healthy level of warmth inside the home. Below are some important information you need to know regarding the right way to maintain your furnace:


Once a year, before the cold weather starts, can be a good time to schedule a check-up for your heating system. However, doing the check-up more than once a year can also have its benefits. Our heating systems are not only affected by the weather, it is also prone to wear and tear and other issues. Consider the nature of your machine when planning for a regular check-up. Different heating systems require different levels of care; each of them having their own specifications. That being said, be sure to check with your contractor about what kind of repairs your heating system needs, depending on its composition.


Check-ups do not really cost much. But, repairs and replacements are for another story.

Here are the top four must-do of a contractor when visiting your house for an inspection:

  1. First off is inspecting the thermostat settings to see if the functions of your heating system is working properly.
  2. Next, they have to make sure that all electrical connections are intact, and should be followed by a voltage testing. This step is done to avoid components from failing in the future, especially during the winter.
  3. Third, the contractors must lubricate all moving parts of the system. Then, they should visit the condensate drain to ensure that there are no clogs and build ups inside.
  4. Last is testing the start-up and shutdown controls, to make sure they operate as per instructions. Then, the filters will be replaced if it is no longer a candidate for a simple cleaning job.

But, if your contractor thinks that there is more to do than a simple tinkering to check the health of your system, then the cost can go up the roof depending on the problem that needs to be solved. If this happens, you now have to start worrying about labor cost, buying parts and components, and how many days will it take to have your system up and running again. On an average, a check-up will cost you less than a hundred dollars. Anything more than that can be considered a scam. So be very careful when choosing your contractors.


If you need more information about your other machines that might need some wintertime repairs like your air conditioner, you can also read up on our blog on when to repair or replace the unit here.


When looking for contractors, make sure that they are credible. Check if they are registered as a business in your town. You can also ask your neighbors for recommendations. A good friendly neighbor will have your best interest at heart when you inquire about these things.

There are many heating and air contractors in Sacramento, California, but very few are reliable and can commit to a quality service.

We at All Year can promise you the best service all year round when you reach out to us with an inquiry or a job order for your furnace repair needs.



When to Repair or Replace Your Air Conditioner System?

Summer is upon us and most people have just started to use their air conditioners. If you have noticed that your unit is not running like it should be, you might be considering the decision to repair it vs. replacing it. There are many factors to take into consideration when making that decision.

First you want to look at THE AGE of your unit. The age of your unit plays a critical factor when deciding to either repair or replace your unit. A great way to help figure this out is by a simple math equation: You take the age of the equipment and multiply that by the repair cost. If the number is more than $5,000, then you should consider replacement. For example, a 10-year-old unit with a $350 repair equals $3,500. It’s OK to repair. Most units are recommended to be replaced every 10-15 years, but if you do not need to service it and it’s still running, repairing it should work just fine.

Next you want to look at the EFFICIENCY. There is a lot of new technology with A/C units out on the market. It is being recommended that units older than 15 years old be replaced with more energy-efficient units. Energy bills are always the highest in summer and winter when you have you’re A/C or heating units running the most. If you do buy a new, energy-efficient A/C unit, it is estimated that you could have a 20 percent savings on heating and cooling costs. That could be a huge incentive to replace your unit.

Another factor to take into account is HOW LONG YOU WILL BE AT THE RESIDENCE. If you are only living at your residence temporarily and the unit is running efficiently, economically it might be a better choice to do repairs every now and then, rather than pay for a brand new unit. If you know that you will be living in the residence for many years, replacing your unit could save you money in the long run. Paying for a good brand new unit will also save you from having to worry every year whether or not your unit will be working adequately.

If you constantly have to have MAINTENANCE done to your unit, this might be an indicator that it’s time to get a new unit. A great benefit to brand new units is that they come with a warranty! This means many years of saving money if there are any issues with your new unit. Just to have that peace of mind is a huge positive factor. On the other hand, you will still want to remember the $5,000 rule stated above. If your repairs are less than $5,000 then it’s okay to just repair it.

Another thing to consider is Comfort & Air Quality. Newer systems do a better job of controlling temperature and humidity, which reduces mold and mildew growth, improving both comfort and air quality in your home. If you have someone in your household that suffers from allergies, newer models can help with filtering out and keeping the temperatures regulated so they can be more comfortable in their living space.

The last thing to think about would be CONVENIENCE. Are you tired of having to constantly maintain your unit, find a part for it, replace your coolant, or suffer thru the heat and cold when it’s not working properly? Those are all reasons to get a new unit. If your unit is keeping you cool, or warm, only needs seasonal tune ups and your energy bills are relatively low, then there is no need to replace your unit.

Signs that indicate your Air Conditioning Unit is on its way out

Before the temperature starts jumping into the triple digits, it’s time to make sure your air conditioning unit is ready to take on the summer heat! In addition to having a regular maintenance check from your Sacramento HVAC professional, its important to know what to look for when it comes to signs that your AC unit could be on its way out, because the last thing you want is to be stuck without a functioning air conditioner during a California summer day!

Below we have put together a list of the warning signs of an AC unit that is about to die; take a look at the 7 signs below and if any of them apply to your air conditioner, be sure to get in touch with your heating and air company today!

7 signs indicating your AC could be on its way out

  1. An increase in your energy bills: Even though you can expect seasonal increases in 
your energy bills during the winter and summer, huge hikes in your energy bill could be an indication that your HVAC system is working too hard. If your air conditioner has to work harder to put out the amount of cool air, there could be an issue with the unit itself and might even need replacing altogether.
  2. Lack of cool air, poor production: An air-conditioning unit is meant to produce cold air, not just blow air around like a fan would, so if you notice that your AC system isn’t making cold anymore there is probably a problem. It’s important to contact your HVAC professional if this problem persists because the issue could be related to a faulty compressor, a leak in the refrigerant, or another mechanical issue.
  3. Poor air flow: Similar to sign number 2, a lack of airflow or an inability to perform at peak levels could also be an indication that your AC unit is on the way out. If after checking the air filters and cleaning them the airflow is still weak, it’s a good idea to call an HVAC maintenance professional to schedule an inspection, as this is a sign of mechanical problems as well.
  4. Frequent repairs: Speaking of repairs, while it’s always important to maintain regular appointments with your HVAC Company, if you notice that you seem to spending more time and money on problems and repairs with your air conditioner, chances are the unit might need replacing. As with any repair or replacement concerns, check with your local HVAC professional for advice before making any decisions.
  5. Constant start-ups: Any out of the ordinary behavior from an HVAC unit is typically the sign of problem. Should you notice that your system is constantly restarting after just being on (i.e., it has to work harder to keep your home cool), make sure you are up to date with your seasonal tune-ups; if you are up to date and inefficient starts and stops keep happening with your air conditioner, it could be time for an HVAC replacement.
  6. Making odd noises: The usual noises associated with air conditioners and heaters you 
are likely already familiar with, but if you ever hear you A/C unit rattling or making high-pitched noises when it’s operating, call your HVAC repair company immediately because this could be a sign that your air conditioner is on its way out!
  7. Inefficient production: Overtime you may begin to notice that your air conditioner doesn’t perform the way it did in the past; for example, different rooms throughout the house may be cooler than others, it may take longer for the house to cool, etc. Whatever the sign of aging may be, it doesn’t hurt to call a local HVAC professional for advice regarding your specific situation.

So why wait to make sure your AC unit is ready for another record-breaking California summer? Give All Year a call today to schedule your quick, HVAC tune-up today!

Getting Ready for Air Conditioner Season

Now that summer is just around the corner, it’s time to prepare our homes for the hot weather to come and one of the most important things on that to do list is getting our air conditioning units ready for the season. In addition to having a standard tune-up performed on your system, there are a few other steps you can take to help get your A/C unit in top shape for the upcoming summer season!

Check your thermostat

First things first, be sure to change the batteries in your thermostat if you haven’t within the last couple of months. You definitely don’t want to be forced to call an HVAC Repair Company over what you think is a major problem, only to find out that the thermostat simply died.

Also consider investing in a programmable thermostat; some of the benefits associated with investing in a new thermostat include an improvement in energy efficiency, and an overall reduction in energy-related bills and expenditures. An outdated thermostat operating in tandem with an outdated A/C unit can be incredibly inefficient; so don’t hesitate to ask your HVAC technician if this is a concern of yours.

Time for a little spring-cleaning!

When it comes to doing your part to keep the air conditioning system of your home clean, there are two main jobs to remember; first, clean the air filters, and second, maintain a clean and clear space around the A/C unit itself. To keep your air conditioner functioning properly this summer, make sure to clean the surrounding area of the unit, including mowing or trimming grass or weeds, removing branches, leaves, etc. Also keep all shrubs and trees at least 2 feet away from the unit.

A clogged and dirty air filter can dramatically impact how your unit functions, as it can cause a back up situation when the air cannot flow through properly, often resulting in the unit seizing up. Additionally, dirty and clogged air filters can decrease the efficiency of your A/C this summer, so unless you have washable air filters, it is important to remember to replace them every 30-60 days.

Keep your home cool by keeping the sun out

Another way to help keep your home cool this summer is by using window coverings, shades, blackout drapes, and other materials made to keep sun from penetrating to the inside of your house. And by keeping your home cooler with methods like that, you also reduce the stress on your HVAC unit because it won’t have to work as hard to keep the inside cool!

Schedule a tune-up with a professional A/C company

An experienced HVAC technician will be able to identify any potential problems during a tune up that could jeopardize the longevity of your A/C system and make your summer a whole lot hotter than it has to be! Not to mention the fact that with regular maintenance, which helps to extend the life and protect the value of the HVAC system, regular checks from a professional technician can help to improve the efficiency of your A/C.

So don’t be afraid to give our friendly staff at All Year a call today, and let us know how we can help you get ready for the A/C season!

How to Improve Your Indoor Air Quality

Everyone makes sure that kids wash their hands to avoid spreading germs. However, germs can be spread in your own home in more ways than you might think.

The Center for Disease Control has reported that poor indoor air quality can actually contribute to respiratory diseases such as asthma, or even cause other side effects such as headaches, nasal mucus, and fatigue. There are many unbelievable statistics to back up these findings. The American College of Allergists report that indoor air pollution causes or contributes to 50% of all illnesses. According to the Texas DSHS, indoor air is two to five times worse than outdoor air.

So why is indoor air so polluted?

There are two main factors contributing to poor indoor air quality.

  1. Direct Air Pollutants
  2. Poor Ventilation

Air Pollutants

Some examples of direct air pollutants include certain cleaning solutions, tobacco smoke, unsanitary heating or cooling units, pesticides, etc. Many of these products are found in your home without your knowledge to the short-term or long-term damage they might be causing. Some people are highly sensitive and might start showing side effects after just one exposure to a pollutant. For example, they might experience eye irritation, headaches, or dizziness.

However, some health effects only present themselves years after a long period of extended exposure to a pollutant. These effects are more serious and often less treatable than the others. For example, someone could learn that they have contracted cancer or serious lung or heart disease.

Poor Ventilation

Your air filtration and ventilation systems act as quality control for the air that is carried around your entire home. This is the air that keeps you and your family alive, so it is a good idea to be aware of its quality. There are a few different options when it comes to air filtration.

You can use a basic, disposable fiberglass air filter. This is a very common choice, because it is incredibly economical. This type of air filter will definitely keep larger particles from getting through, which will keep large amounts of dust and dirt out, but it will do nothing to actually clean the air and rid it of harmful germs.

It is up to you to examine your air filtration needs and determine which resource will best take care of your home or building.

Why is my furnace producing weird odors?

What those smells coming from your furnace could indicate and what to do about them

Many homeowners have experienced smelling a weird odor coming from their furnace and wondered what it could be, but did you know that those odd smells could actually be an indication of a problem with your furnace? While’s it’s not particularly uncommon for an HVAC unit to cause some type of smell upon its first use after a long summer, some odors are potentially a sign of a major problem. Here are 3 of the most common smells that your home’s furnace could produce and what you should do about it:

Rotten egg smell

One of the easier smells to recognize is the odor of rotten eggs, what many think of as that sort of classic, offensive sulfur smell. The fact that the smell is so pungent is a positive thing however, because it lets homeowners know about the presence of a gas leak coming from the furnace. Since gas has no natural odor to it, manufacturers add the sulfuric rotten egg smell to the gas with the purpose of acting as an indicator of the presence of gas.

If you happen to notice this smell its imperative to immediately turn the furnace off, and open up the windows your home to let the gas out. Be sure to call your HVAC specialist as soon as possible and let them know that you think your furnace has a gas leak, and leave your house to let it air out if the smell is overpowering.


Related post: is your furnace blowing out cold air?


Burning electrical smell

Similar to how the smell of rotten eggs is very distinct, the odor created by burning or overheated electrical wires is hard to mistake, especially since most homeowners have probably not had to smell such an odor in their home’s before. The smell of burning metal or wires coming from your furnace is something to take very seriously, as it likely part of the mechanics within the furnace that is overheating or in the process of doing so.

Your HVAC system could also produce this smell when worn out rubber and plastic pieces within the furnace start to overheat, yet another reason why it’s so important to maintain regularly scheduled furnace checks from your HVAC service technician. No matter what the cause is if you notice any burning smells coming from your furnace, turn your system off right away and contact your heat and air specialist for an immediate appointment.


Burning dust smell

After not using your furnace for several months, dirt and dust tends to accumulate in the ducts and vents and therefore could cause a smell when you first turn on your furnace after it being off for an extended period. However, if that burning smell persists for too long, consider changing the air filter of the unit. Should that not clear up the smell, it’s time to give your HVAC technician a call.

Since your air conditioning unit uses water to create cold air, condensation does occur and therefore, there is a potential for mold to form within your HVAC system. A musty smell coming from your furnace could be a sign that mold has formed in the duct system and is in need of a thorough cleaning. Be sure to call All Year HVAC for service.

Even if you aren’t sure what the reason or odor you smell could be, it’s always a good idea to call your local heating and air expert just to be safe. And remember that the best way to prevent such issues from happening to your HVAC system in the first place is by regularly scheduling routine inspections and tune-ups from your trusted service technician.
