Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

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.

Five Most Common AC Problems (And How To Fix Them)

by Billie Carlson

In these hot summer months, your air conditioning unit can be a lifesaver — until it stops working. If you've ever experienced the pain of waking up in the middle of the night, only to find your house is ten degrees hotter than it should be, you know how important it is that that machine is operating efficiently.

Unfortunately, there are a lot of issues that can plague your HVAC system, some of which are more common than others. Below is a list of five of the most common and how to fix them. If you're uncomfortable performing any of these solutions yourself, please hire air conditioning repair services to get your system back in tip-top shape.

Clogged Air Filter

Ideally, your AC filter should be replaced every 2-3 months, depending on the season and where you live. Failure to do that can result in your system working double-duty just to pump out the same amount of cold air, prematurely aging your unit and causing breathing problems in the process. It's a simple fix and one that should immediately alleviate a lot of air conditioning repair woes.

Broken Thermostat

In an age of smart thermostats, you can almost know that there's a problem with your AC system before your system even starts to malfunction. Still, if your thermostat is broken, not only will you be unable to regulate the airflow, but it may also damage the unit too. Replacing it is a snap and should be relatively inexpensive.

Dirty Condenser Coils

Included in nearly every HVAC company's maintenance plans and air conditioning repair services is cleaning the condenser coils. These little guys are responsible for converting the hot air outside into cold air inside, but they're unfortunately prone to collecting dust as well. Make sure they stay operational by cleaning them regularly, or hire an air conditioning repair company to do it for you.

Tripped Breaker

If your HVAC system all of a sudden stops working, the problem may be as simple as checking the breaker box. In some situations, the breaker can be overloaded and trip the system, causing the entire thing to shut off. Before you switch it back though, have an HVAC company inspect the problem to make sure there's not a bigger issue brewing.

Collapsed Duct

This is one that you'll want to leave to the professionals. Very common in older HVAC systems, a collapsed duct can limit the airflow in and out of your system, causing major issues with regulating temperature and prematurely aging the system. Get it fixed as soon as possible.
