No homeowner wants to run into problems with their central air conditioning, especially during the hot and humid months of summer. Often times, there are underlying signs of AC trouble long before something major happens. Unfortunately, these "red flags" are commonly overlooked by homeowners.
By having a better understanding of what to look for when it comes to air conditioning problems, you'll know when to call your HVAC professional. From there, you can stay on top of necessary repairs or know when it's time for new air conditioning installation.
Your air conditioner is going to make some noise while it operates, but the amount of noise can vary greatly from one unit to the next depending on its age, features, and even the layout of your home and its ductwork. You most likely know best when it comes to what's a "normal" noise for your AC and what's cause for concern. If you notice any unfamiliar noises or if your AC is making any persistent squeaking or banging noises, it's time to call an HVAC technician right away.
The same goes for unfamiliar smells; generally, you shouldn't smell anything while your air conditioning is in operation. However, a stale smell is relatively harmless and likely means that your air filter simply needs to be replaced. If you notice any burning smells or gas odors, however, this is something that should not be overlooked and could potentially be dangerous. Call your trusted HVAC company right away and stop using your air conditioning in the meantime.
Have you noticed recently that some rooms in your home seem to be cool while others are too warm? This could be indicative of a problem with your AC unit or the ductwork in your home. Either way, it needs to be addressed sooner rather than later. The same goes with an AC unit that's not blowing out cold air. This could be a problem with your refrigerant supply or even a bad coil.
Increased Cooling Costs
If your monthly cooling costs seem to be higher than normal for no logical reason, this may also warrant a call to your HVAC professional. An inspection of your AC system may reveal issues that are harming efficiency and thus causing the system to work harder than it needs to. A minor repair or tuneup may be all that's needed to get your system working efficiently once again.
