Why Does My Furnace Keep Shutting Off?

By Air Care Heating & Air Conditioning

Have you used your furnace in the past and found that it shuts off quickly after turning it on, seemingly for no reason at all?

Even though this problem is annoying at best the reality is that most furnaces begin to shut off by themselves when the furnace starts to break down or it’s not been properly maintained for a while.

Thankfully, you can avoid high energy bills due to your furnace continuing to shut off on its own by following these trouble shooting tips.

Tip #1 – You Have a Dirty Air Filter

One of the most common causes of a furnace turning off by itself only after a few minutes of use (short cycling) is a dirty air filter.

Keeping your air filter clean is important because the heat exchanger in your furnace needs the air to continually blow over it to keep it from shutting down.

If you’ve found your furnaces air filter to be dirty you should determine if the filter is washable then wash that filter yourself or you should replace that air filter with a new one.

Tip #2 – Your Thermostat Has Issues

Did you know that if your thermostat is placed too close to a heat source like sunlight or another heat source it will think your home is too warm and shut the furnace off? If you suspect this is the case you should contact an experienced HVAC technician and have your thermostat moved to another wall in your home.

Let’s say that your thermostat isn’t directly near a heat source in your home; the reality is that another technical issue could be causing your thermostat to malfunction and you should hire a technician to have it repaired and possibly replaced (if needed).

Tip #3 – You May Have the Wrong Sized Furnace for Your House

Last of all, but most important, another reason why your furnace is shutting off too quickly could be due to you having a furnace that’s too big for your house and it’s heating your home too quickly.

Unfortunately, the process of your home heating up too quickly and the furnace shutting itself off will only continue until it breaks down and needs to be repaired or replaced.

What’s the solution to the problem? Hire a contractor to come to your house and do various calculations, including a heat load test, to determine if your furnace is the wrong size and should be replaced.

Are Some Rooms in Your Home Colder Than Others?

By Air Care Heating & Air Conditioning

One of the most common problems that many people have in their homes is when they find out that some rooms are hotter or colder than others regardless of the temperature that the thermostat in the home is set to.

Although it may be frustrating to experience this problem, the reality is that it’s fairly common problem and there could be one or more issues causing it which may include the following:

Dirty Air Filter

Yes, it’s true, one of the most common reasons why some rooms in your home may be hotter or cooler than others could be due to a dirty air filter in your HVAC unit.

Since air filters are so affordable these days you should replace yours immediately especially if it’s not been replaced in the last six months or so.

The Vents Are Closed

Another thing which could be causing one room in your home to be hotter or colder than others on any given day is because the vents are closed. To solve this problem check all of the vents in each room, reopen any closed vents, and see if the temperature in that room matches the rest of the home once the A/C or heat has been turned on.

Open Windows

Have you checked to make sure all windows in the home have been closed?

This is another common reason why some rooms may feel cooler or warmer than others during the year.

Most people think that the windows in their home have been closed but if you have small children it’s possible that they may have left one window partially cracked open and this could be enough to let in a breeze or draft into your house.

Your Home May Have Air Duct Issues

Last of all, but most important, another reason why one or more rooms in your house may be cooler or warmer during the year could be due to air duct issues.

You could have air ducts that are leaky, crushed, kinked or damaged and those ducts are causing uneven temperatures in your home.

Why Is My Filter Black?



One of the most important parts of any heating system in a home is the air filter.

The filter serves a vital function of keeping dust, dirt, and debris from getting into the heating system, settling on equipment and causing long-term damage to the heater including its internal components.

Besides protecting the heaters internal components, the air filter also helps to filter the air in a home as well ensuring that people who have allergies or breathing issues are able to breathe easily.

Why Is Your Air Filter Black?

Let’s say that you recently pulled your air filter out and found that the filter has a black color. Thankfully, there are a variety of reasons why this happened including the following:

Soot from candles – If you’ve enjoyed burning candles in your home lately, the black air filter could be a result of excessive soot that’s been collected from your candles.

One of the best things that you can do is limit the number of candles that you burn in your home since soot can also settle on your walls, floors, and lungs of any residents in the home.

You should also replace your air filter and check it again within 1-2 weeks to see if your filter has retained it’s light color.

Fireplace Soot – Do you have a fireplace in your home? If so, you should have it checked to make sure that your fireplace is venting as it should because excessive soot from a fireplace can also lead to a black air filter.

Carbon Monoxide – Another reason for a black air filter is carbon monoxide. This could be caused by your fireplace or any other combustion appliance that you may have in your home.

To ensure that your home isn’t dealing with high levels of carbon monoxide you should have all of your carbon monoxide detectors checked immediately. You should also have your fireplace and other combustion appliances checked as well to ensure that they are functioning normally.

Mold – Last of all, but most important, another reason why your air filter is black could be due to your air conditioners evaporator coil becoming damp with condensation. Once this happens that condensation can also collect dust and dirt then transfer to your furnace, eventually turning to mold if it’s not been cleaned in months.

Prevent this problem from happening to you by having your furnace cleaned as soon as possible especially if you want it to continue functioning normally during colder months when you may use it the most.

When to Change Your Furnace Air Filter

Thanks to recent data from the National Fire Protection Association we know that a clogged air filter can block airflow and also cause premature breakdown of the heater itself.

Prevent your heater breaking down and commit to changing your heaters air filter every 60 to 90 days because this will also ensure that your system will continue running as per the manufacturer’s specifications.

Why Is My Furnace Blowing Cold Air?

By Air Care Heating & Air Conditioning


It’s November in Southern California and even though it’s not uncommon for us to have summer-like conditions, we’ve also had the weather change quickly, get colder and this is a time to start turning on the furnace. 

When the weather changes during the fall and winter months in SoCal one of the first things that people want to do is turn on their furnaces.

Even though we expect our furnaces to blow warm air when we need them it’s not uncommon for some furnaces to blow cold air, indicating that there are serious problems with the furnace that need to be fixed in order for it to start blowing warm air again.

If your furnace is currently blowing cold air, this article will provide you with the reasons why your furnace is blowing cold air and what you can do to get it blowing warm air once again.

Your Thermostat May Be Set to On

One of the most common reasons why most units blow cold air when they should be blowing warm air is because the thermostat is set in the on position. This means that the furnace is constantly running and is unable to heat the air coming out of it.

The solution to this problem is for you to set your thermostat to auto because your furnace will stop running all the time and only turn on when your home reaches the temperature which you set your thermostat for.


Your Furnace May Have Overheated

Does your furnace start out by blowing warm air but then starts blowing cold air? If so, this problem may be caused by the limit switch, a safety feature in all furnaces that will turn the burner off.

What causes the limit switch to turn on? In most cases it’s due to the air filter in the furnace being dirty, and when that filer is dirty your furnace will have to run longer to keep your home warm until the furnace eventually overheats.

What’s the solution to this problem? It’s simple, try replacing your air filter with a new one and then wait to see if your furnace starts to blow warm air once again.

Your Furnace’s Pilot Light May Have Burned Out

Last of all, another common reason why most furnaces start blowing cold air instead of warm air is due to the furnace pilot light burning out.

To fix this problem you should clean the pilot light, turn the gas valve to the on position, and relight the pilot light yourself.

In most cases, the pilot light will state on but there are other cases where it could burn out again and this could mean that your furnaces thermocouple may need to be replaced or adjusted by a professional.
