Almost 90% of American households used air conditioning in 2020, the last time the U.S. Energy Information Administration took a survey. Chances are, if you’re part of the 90%, you’ll run into an AC unit issue at some point. Running into HVAC problems doesn’t have to cause a headache or panic.

Chances are, the problem is a common one and maybe even an easy fix. Read on to learn about some of the most common HVAC issues you can run into this summer.

1. Refrigerant Leaks

Refrigerant is an important component of the heating and cooling your AC unit does. This liquid is responsible for absorbing heat in your unit and making sure the air is cool and not humid.

You may have a leak if you notice your home isn’t cooling off the way it normally would. If you think it may be because of a refrigerant issue, resist the urge to simply add more liquid to top off the unit’s supply.

This will just drain more refrigerant and will be a waste of money. Plus, it’s bad for the environment! It’s always a better idea to locate the leak, if possible, and call a professional.

2. Clogged Drain Lines

A drain line is an essential part of your home cooling system, so it’s important to make sure they are clean.

Drain lines are responsible for transporting the humidity the air system collects out of your home. Since the inside of a drain line is wet, it may collect mold, mildew, algae, or dirt and become clogged over time.

Clogged drain lines might even back up into your AC unit, which could potentially damage other parts of your system.

You can occasionally use a wet-dry vacuum to clear out your drain lines before they become a bigger problem.

3. AC Filter Issues

Your HVAC unit filter has a big job, so naturally, it needs to get changed out every once in a while. One way to tell if you have filter issues is if you notice your home isn’t cooling down the way it normally does.

If airflow from your unit is blocked by a dirty filter, it can’t fully cool down your home or maintain cool temperatures like it’s supposed to.

It’s important to call a professional to change your filter if you can’t do it yourself. Otherwise, a clogged filter can lead to higher bills and a frozen coil.

4. Blowing Warm Air

An HVAC system blowing warm air instead of cool air is a common problem and a sure sign something is wrong with your unit.

This can be caused by a variety of things, including a broken thermostat or a disconnection between the thermostat and the unit. It may also be a broken compressor or blown breaker.

5. Dirty Condenser Coils

Dirty and clogged coils happen naturally over time, so if you haven’t checked them in a while, it might be time to.

Condenser coils help to remove warm air from your AC unit. If they are clogged or too dirty and don’t get cleaned, it can shorten the efficiency and lifespan of your AC unit.
