Signs that your AC isn’t working properly

With summer in full swing, you’re likely keeping cool with a little help from your HVAC unit. Well, as long as your system is running as efficiently and effectively as it should be.

If your unit isn’t functioning the way it should be, you’re likely in need of a little professional help. Here are six things to look for, so you aren’t left sweltering in the summer heat.

6 reasons why your AC isn’t keeping you cool

Poor air flow

If you notice a decline in the amount of air flow coming from your vents, it’s a good idea to check the air filter.

If air filters are heavily clogged, they reduce airflow and put unnecessary strain on the entire HVAC system. Air filters should be replaced every 1 – 3 months depending on use.

Weak airflow can also be caused by a damaged blower or an issue with the unit’s compressor—both issues that require professional help.

Warm air

When you notice that the air coming from your vents isn’t as cold as it should be—or even cold at all—it’s a clear sign that your unit isn’t working properly.

One reason could be that your system is low on coolant, but there are a number of other potential causes that aren’t as simple to repair. If your unit isn’t cooling efficiently, it’s important to evaluate the entire system and pinpoint the cause of your system’s poor performance.

Strange noises

Well-maintained and properly functioning air conditioning units are meant to run quietly. Your systems shouldn’t make any strange noises when starting, stopping, or running. Noisy operation is a good indicator that something just isn’t right.

Squealing, grating, or grinding sounds imply that something is wrong inside the unit, and could mean that you need a replacement unit. A squealing noise means that the belt has slipped out of place. It may also indicate that a metal component inside the unit requires lubrication. A grinding sound could mean that the motor’s bearings are broken.

Failure to service the unit could result in a pricy breakdown, so it’s a good idea to call in a professional—like us!


If you notice a puddle of water near your unit, it could be that you have a dirty air filter. A dirty air filter will cause ice to form on the unit’s evaporator coils. When the ice melts, it drips and creates a puddle of water around the unit.

There could also be a crack, a hole, or a block in the drain tube, or a plugged condensate line. Another—more serious—issue could be a refrigerant leak. Refrigerant leaks can cause serious health risks to your and need to be repaired at once.

It’s a good idea to review the signs of a refrigerant leak to make sure that you don’t have one.

Foul smells

Pungent or foul smells normally mean that your conditioner’s wire insulation has burned out. Musty smells often indicate that there is mold inside your unit or ductwork, and should be taken care of immediately.

High energy bills

Your HVAC unit uses the largest amount of electricity in your home. If your electricity bills have spiked since last season, there’s a good chance that your unit is the culprit and in need of a check-up.


In order to avoid any of these issues, it’s important to care for your HVAC unit on a regular basis.

Even if your unit doesn’t need replacing, getting services and repaired will boost its efficiency and save you money.
