Signs Your A/C Needs Repair

There are several signs that indicate your air conditioner may require professional repair services. If you notice any of these signs with your own system, give us a call or fill out this form to request a service call.

Thermostat Issues

When your air conditioner isn’t working properly, sometimes all you need to do is replace the batteries in your thermostat, adjust the settings, or change your filter. If you’ve done all that and your system is still not right, there may be a larger issue at hand.

Unfamiliar Noises

Your air conditioner should make the same consistent noise while it’s running. If you’re noticing an unfamiliar noise coming from your system, it could indicate an issue. Clattering, clanking, and thudding are all noises you should be concerned about. If you’re not sure what may be causing the unfamiliar noise in your unit, schedule an A/C repair service from a professional repairman.

Noticeable Odors

Sometimes harmful particles such as mold and mildew can start to grow within your air conditioner, which can produce a strange smell. You should also take note if your unit is giving off a burning odor. This can lead to hazardous issues if the unit isn’t promptly repaired.

Frequently Asked Questions: Air Conditioning Repair

Do you have a question about your air conditioning unit? Below, we answer some of the most common questions about A/C repair. If you don’t see what you’re looking for, feel free to email us with your questions.

How do you troubleshoot an air conditioner?

There are several methods you can use to troubleshoot your air conditioner while you wait for the technician to arrive. First, take a look at your thermostat to ensure it’s working correctly. You should also ensure the condenser isn’t blocked by any objects or dirt. Additionally, dirty filters can also cause your air conditioner to malfunction. Lastly, you can inspect your system to ensure no ice has formed on the coils.

Why is my air conditioner running but not cooling the house?

When your air conditioner is low on refrigerant, your air conditioner may have a difficult time efficiently cooling down your house. Double-check your refrigerant line on your unit and make sure there is enough in your air conditioner to properly cool your house.

Why did my A/C suddenly stop working?

There can be a number of reasons why your air conditioner may suddenly stop working. Most often, sudden A/C failure is a result of inadequate maintenance and servicing. Other causes for air conditioner malfunction include a blown fuse or tripped circuit breaker. To prevent your A/C from malfunctioning, make sure you schedule routine inspections and maintenance servicing.
