5 Signs Your HVAC Unit Needs A Checkup

We all love it when summer rolls in. The warmer weather combined with longer days is a perfect environment for vacations, outdoor activities, and late nights out with family and friends. However, with the heat comes the need for your HVAC system to keep you cool and comfortable.

Long before the summer is here, it is best to ensure that your HVAC system operates, as it should. A well-functioning HVAC unit will assist you in avoiding having to suffer through sweltering whenever you have to be indoors. Here are some telltale signs to watch out for:

1. Strange Noises

Strange noise here refers to any out-of-the-ordinary sounds your HVAC might produce. These may include such noises as rattling, hissing, squealing, grinding, or clunking.

In most cases, these sounds show that there may be a loose part in your HVAC system, a problematic belt, or another related issue.

Therefore, do not wait for the problem to escalate into a major issue. These issues eventually lead to a complete shutdown of your HVAC system. Enlist professional services like HVAC service in Millcreek to handle the matter.

2. Inconsistent Temperatures

In most cases, a general HVAC system should generate a consistent temperature throughout your home. There are multi-zone HVAC systems with features that provide varying temperatures within the same building; however, the system will display whether this feature is available.

Therefore, if you notice that your HVAC system suddenly produces inconsistent temperatures, it may be time to schedule a checkup. Varying temperatures from room to room refer to one room freezing while another room is warm, or even from floor to floor.

3. Skyrocketing Power Bills

If your power bill suddenly and drastically increases for no apparent reason, a place to start inspection would be with your HVAC system. This is especially the case when a skyrocketing power bill comes with any of the mentioned signs of a faulty HVAC system.

An HVAC system that continuously has problems may work overtime to keep up. The added stress will affect your power bills and leads to a complete system failure. Therefore, to arrest the matter in good time, ensure you call for a checkup as soon as you notice these inconsistent temperatures.

4. Strange Smells

A strange and lingering smell from your HVAC unit is another dangerous signal. The smell could be a burning, rotten, or musty stink from your outdoor compressor or AC vents. 

If the smell is a chemical smell, then even more reason to have a professional check out your system to rule out the possibility of a toxic leak.

5. Power Fluctuations

Unlike your refrigerator, manufacturers of these units do not design HVAC systems to turn off and on randomly. Therefore, once you notice your HVAC unit randomly turns off and on, then that would be a good time to call for a professional checkup.

Usually, the problem may be that your power supply is insufficient to keep your unit running fluidly and will not take much to fix. However, left unresolved, a short-cycling HVAC unit will damage your entire power supply, which is a fire hazard.

Alternatively, it may occur because of overheating of your HVAC system. However, regardless of its cause, the risks are still the same and equally dangerous.


Any of the above signs begin as minor problems. However, left unaddressed, all these will lead to more severe issues that will incur higher repair costs.

Rather than face these high repair costs, how much better it is to schedule a checkup even when you are not so sure of the problem.
