Common AC Problems

You can bet that you’ll need an AC repair at some point in your life. When that time comes, you should be ready. Knowing everything you can know about AC repair means you’ll have less of a headache when your air conditioner breaks down. Take a look at everything you need to know about AC repair and how a Hudson heating and cooling specialist can help.

Common AC Problems

Although there’s a long list of possible AC repairs, there are only a few repairs that commonly affect local homeowners. All of the following are reasons your air conditioner might be in need of a repair:

Refrigerant Leak

Your refrigerant runs through lines that are susceptible to damage. Over time, they break down and result in small leaks. The refrigerant can’t cycle through a closed system and begins to deplete. Unfortunately, your AC will need to work hard to cool your home. After enough refrigerant disappears, your air conditioner won’t run at all. 

You can usually identify a refrigerant leak by the following issues:

  • High utility bills with no explanation 
  • Warm air blowing from the air vents
  • High humidity inside your home
  • Hissing noise from your exterior unit
  • Poor airflow

To fix the issue, a technician needs to identify the leak and patch it. Then, they need to refill the refrigerant so your AC can get back to work. This is not a DIY job, as people who handle refrigerants need special certifications.

Drainage Problems 

Believe it or not, it’s normal for an air conditioner to leak some water. What’s not normal is for your AC to leak water onto your floor or to puddle around the exterior unit. If you notice unusual leaks, you have a problem. 

The condensation from your AC travels into a drain pan and out through a drain line. However, a clog could keep the system from draining the way it’s supposed to. If you have high humidity in your home, you could also notice a leak. 

Drainage issues do more than affect the performance of your AC. They also cause water damage to your floors and walls. When you have water in your home, you also have the potential for mold growth. The health risks are high, so you want to avoid this at all costs. Fortunately, a repair could be as easy as having a Hudson heating & cooling specialist vacuum out your drain line.

Broken Compressor Fan

The compressor is an essential part of your AC, and it’s also a component that’s likely to require a replacement at some point in time. If the fan doesn’t work, hot air won’t disappear from the air in your home. The system could completely fail as the AC safety controls turn off the system.

If you have a broken compressor, you could notice the following:

  • Strange banging or screeching noises from the outdoor unit
  • No hot air being released from the outdoor unit
  • Warm air inside your home
  • The circuit breaker trips repeatedly

In the event that your compressor issue is from an electrical problem, you might need a simple repair. But there’s a chance that you need to replace the compressor, and this is a costly fix. Like most other AC repairs, this is not a do-it-yourself job. 

Frozen Coils

Frozen coils are a problem but also an indication of another malfunction in your system. If your AC doesn’t work the way it should, the condenser coils could become icy. Usually, the cause of this is poor airflow, dirty filters, or a clogged drainpipe.

You might think that thawing the coils is a quick fix for this issue. However, thawing the coils is only a bandaid solution. Unless you address the real problem, the coils will continue to freeze, and the components of your AC will undergo damage. 

Before you call for help, check the filters. If a dirty filter is to blame, you can simply change out the filters. But, if that doesn’t work, you may need to have a professional clean your drainpipe or check for a refrigerant leak.

What Constitutes as an Emergency AC Repair?

An emergency AC repair is anything that demands immediate attention. If you can’t figure out how to change a setting on your programmable thermostat, you don’t need to call for help right away. However, a burning smell coming from your system warrants immediate attention. You should never wait to call for help when there’s a fire danger. 

Common HVAC emergencies include refrigerant leaks, electrical problems, and anything else that concerns you. On a hot day, a broken AC is certainly a reason to call for an emergency repair. The high temperatures aren’t only unpleasant – they’re dangerous. You need cool air to prevent you from suffering from heatstroke.

If you have a problem with your AC and aren’t sure if it counts as a plumbing emergency, you can call your plumber. They should be able to advise you and help you make the right decision. If you don’t need an emergency service call, you can wait for the soonest availability and save money. 

What Should You Do Before You Call for an AC Repair?

No one likes to waste time and money. If you call an HVAC technician for help before you do some minor troubleshooting, you could be doing just that. Try doing all the following before you make a phone call:

Check the Thermostat Settings

If your thermostat is set too high or set to off mode, it won’t cool your home. You should always check your thermostat to make sure your problem isn’t from a bad case of user error. To test your thermostat, drop the thermostat low enough that it should start a cooling cycle. Make sure it’s not on vacation mode and check that the fan is set to auto.

Check the Power

The last thing you want to do is pay an HVAC technician to flip a breaker. If you had a power surge, your AC might not be working because of a tripped breaker. Find your breaker box and make sure the switch is set to on. If it’s not, flip the switch and turn it on. 

Change Your Air Filter

A quick air filter change could resolve all of your troubles. Replace all of the air filters in your home and see if that gets your AC running.
