7 Early Signs That Your Air Conditioning Needs Service

One of the toughest parts about being a homeowner is knowing when a problem is severe enough to call in a professional.

Fortunately, a bit of education on the basics of HVAC systems can give you a good idea of which issues need attention. Here are seven early signs that your air conditioning needs service. If you notice any of them in your home, it is time to give us a call.


Have you ever heard your system make a strange noise? Some of the most common of them include squeaking, grinding, and grating. While these issues might not seem like an urgent matter, especially if your AC is still running smoothly, they could be indicative of more significant problems. For this reason, we advise getting your system checked by a professional.

Hot Air

The function of an air conditioning unit is to take in air, cool it, then disperse it around your home. Unfortunately, these systems often fail. The best indicator to watch out for is a lack of adequate cooling. If hot air is coming out of your vents, it is definitely time to explore a repair or replacement.

Spotty Cooling

A less obvious indicator of a dysfunctional air conditioning system is spotty cooling. This issue will present itself in the form of “hot spots.” You should be able to detect these areas, as almost every one of us has a reliable sense of temperature.

Poor Air Flow

If your air isn’t following correctly, you could have up to three problems. They include malfunctioning machinery, a leak in your ductwork, or an issue with your vents. Two easy fixes are vacuuming those vents and changing filters. If those do not work, you may have a broader problem that will require professional help.


One of the most apparent indicators of air condition dysfunction is a leaking unit. These machines are built to keep all of their moisture inside, so this development is definitely a problem. If you’re fortunate, you might have a blocked drain tube. If not, your system could be leaking refrigerant.


A strange or foul odor is an indication that something may be growing in your system. Whether that is bacteria in the AC unit or mold in the duct work, you should resolve this issue immediately.

Rising Electric Bill

One thing that homeowners often notice is that their electric bill starts to rise for seemingly no reason. The cause of this issue is often air conditioning issues, which make the system work harder for the same result.
