We rely on your AC system to keep the home at a comfortable temperature year-round. HVAC systems include complex machinery, accessories, and vents that extend throughout the home, so there is a chance
for this complex system to stop working properly. We’ve rounded up some of the most common problems and how you can fix them yourself.
Unit will not turn on
If you try turning your unit on and it doesn’t, explore these possibilities and you could have your unit back and running in minutes
Check your breakers to make sure they are not tripped. Also, make sure the unit is plugged in correctly.
Check the pan under your unit to see if there is standing water. If so, there could be a clogged drain. Try emptying the pan and flushing the drain line to see if that allows your system to work once more.
This is especially a problem with automatic thermostats that may have been improperly set or that reset after a power outage.
The Unit Shuts Off Unexpectedly
If you find that your AC runs, but turns off unexpectedly, you may have a clogged filter or are using one that does not fit your unit well and restricts air flow causing your unit to shut off.
Try changing your filter on a regular basis, and using a filter designed to fit the unit and your needs. A clean, well-chosen filter will assure that the air flows through the system easily and the unit runs with no problems.
My Furnace or AC is Whistling
When your furnace or air conditioner is blowing, you should simply hear a gentle blowing. If you hear whistling, maybe something is wrong.
You may have a problem with the fit or current condition of your filter. If the filter has not been changed in a while, the filter shape could have changed and be the cause of this whistle.
If you are changing your filter regularly, it could be that you are using the wrong size filter. Measure the actual dimensions of your filter and get the perfect fit for your unit.
The Condenser Isn't Running Smoothly
The condenser is the portion of your HVAC unit that is outside your home. One common problem with the condenser is that it gets blocked by leaves, grass and other residues.
Make sure the area surrounding your condenser is clear of all debris by trimming grass around your condenser and raking or blowing leaves away from the unit. If you need to clean the residues inside the condenser make sure the unit is
completely off and unplugged to keep it safe.
There are certainly other issues that may crop up with your AC system. However, being able to fix these simple issues yourself will save you money and help you keep your system in good shape for a long time.
