If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.
Your home's AC system is extremely important, since it helps maintain comfortable temperatures inside. At some point, though, it will experience issues. Here are some of the most common problems with AC units and ways to repair them.
Dirty Air Filter
Dirt and debris have a tendency of collecting on the air filter over time. When this filter gets too dirty, it can no longer work effectively, and your unit is thus more susceptible to overheating won't last as long.
Fortunately, fixing this problem is as simple as finding a suitable replacement. There are many replacement filters you can choose from, but one of the better types is a reusable filter. It can be used over and over, as long as it's properly cleaned at the correct intervals. HEPA (high-efficiency particulate air) filters are also popular, as they help your AC system run more efficiently.
Faulty Thermostat
Sometimes the problem isn't with your AC unit at all, but instead lies with the thermostat. You'll know if your thermostat is faulty if it never switches your AC unit on. Generally, once you turn on the thermostat to the cool setting, you should hear a clicking sound.
If you don't, you'll need to find a suitable replacement, much like you did with the dirty air filter. For the replacement, consider a programmable thermostat. It will give you the unique ability to preset cooling cycles at certain times during the day. This way, your AC unit won't constantly run and drive up your energy bills.
Refrigerant Leak
One of the more concerning problems with AC units is when they leak refrigerant. When this happens, your AC unit can't properly cool air. For this repair, you'll certainly want to hire a licensed HVAC contractor from a company like Air Pro Services.
They can safely and effectively execute a leak detection test using fluorescent dye. It's sent through your HVAC system's refrigerant lines. Then, all the contractor has to do is use a special UV light to pinpoint where the fluorescent dye leaked out from. The contractor will then patch up any punctured or structurally compromised sites.
No matter what type of AC unit you have, it will experience problems at some point. However, as long as you learn some basic information about common problems, you can address them head on. At the very least, you can identify issues and then contact air conditioning repair specialists before severe damage occurs.
