Your HVAC system is an important part of your home. It is designed to help keep you cool in the summer and warm in the winter. It can keep the air filtered and clean in the home and even helps keep some of the humidity far away, even when it is bad outside. You want this system to work well and last a long time. But over time, there are some common problems that may appear that you need to worry about and if you don’t get them fixed quickly, they can shorten the lifespan of your system as well. Some of the most common HVAC problems that you may need to worry about include:


Your filters are an important part of this system. If they get clogged or dirty, then they will cause some issues with the rest of the thing as well. The good news is that these are one of the easiest things to prevent problems with. If you take the time to swap out air filters every 2 to 3 months, or as often as is recommended by the manufacturer, it can help keep things clean and tidy along the way.

The problem with your filters getting dirty is that they will restrict the amount of air that can get into the system, which can cause a number of issues. This will put more strain on the system, can make the energy bills higher, and can even overheat the system so that it stops working. It is a good idea to keep some filters on hand to make sure that you are prepared and can change them on time.

So, What Exactly Is An HVAC System?

A Thermostat That Doesn’t Work

When your air conditioner or furnace stops operating properly, the problem may not lie with the system itself, but there may be an issue with the thermostat. If it does have this problem, the system will start to turn itself on and off erratically and it can even shut down completely. You may want to take a look back at the user’s manual to make sure that you have the thermostat set up well and then check if it is time to replace the batteries. If you find that the thermostat is still not doing the job it should, then you need to call in the professionals to help.

Tripped Circuit Breakers and Blown Fuses

Both of these can be common if your HVAC system is running all the time. This is most common when you have some extreme weather events going on and you should expect that. But if it is happening when the weather is not extreme, then this can be a problem. If the air filter is clogged and the system is working harder for that, then you may see this problem as well. You can first try replacing the filter, especially if it looks really dirty at the time. If that doesn’t work, then call in an HVAC technician to take a look and help out.

Water Leaks

Do you notice that there are some puddles of water around the HVAC system? This is not a good sign at all. This is often caused due to a clogged condensate drain line. When the air conditioner is doing its job well and pulling the excess humidity out of the air in the summer, the water droplets are supposed to collect in a drain pan. Then it is funneled outside through the drain pipe. If this pipe is clogged up, it can cause water to spill onto the floor. This is not a good sign and can cause mold and damage around the property as well.

Refrigerant Leaks

The refrigerant leaks of your system can be a big problem that you need to fix. Without this chemical in the air conditioner, your home will not stay cool. When the leak develops, one of the first signs to look for is that warm air starts to blow from the vents. You may notice that the evaporator coil is frozen when you look at it or there is a hissing sound from your unit. Refrigerants are often dangerous to handle, so having an HVAC professional stop by to recharge it and to handle all of this for you is a good idea.

Unusual Noises

You should never hear anything unusual from your HVAC system. If it is making strange or loud noises, this is a cause for concern and you need to inspect it with the help of a technician as soon as possible. If you hear a rattling or banging noise, it is an indication of a broken or loose part, while a hissing sound could be a sign that the refrigerant is leaking. You may also hear things like clicking and screeching in the system. This is never normal and you will want to call in the professionals to take a look and see what is wrong.

Poor Airflow

This is actually one of the most common problems with an HVAC system. It can include air filters that are clogged, an obstructed condenser unit, thermostat issues, blocked vents, leaks of the refrigerant, and dirty coils. It is really hard to know what is causing it in particular, which is why you may want to call in the professionals to take a look and do some of the diagnosis for you. This can save a lot of problems and ensures that you are able to keep the system safe for a long time to come.
