Key Signs That Your Air Conditioner Needs Repair

Promoted Post

All your electrical devices, including your air conditioner, will stop working or have some other kind of problem at some point. This issue will prevent the unit from functioning normally, and depending on the nature of the problem, it may finally make the item utterly worthless. Thus, this article will discuss the top indicators that your air conditioning unit needs repair as soon as possible.

The Air Is Not Cold

If the air circulating through your vents is not as cold as it was, then this indicates that your system is working harder than it normally would to maintain consistent temperatures. This might be the result of several problems, such as a leak in the refrigerant or a low level of it, issues with the condenser, or leaks in the ductwork.

The Airflow Is Low

Your fan, which is involved in pushing all of that wonderful, cold air through the ductwork, is prone to some problems that may greatly hinder airflow. These issues might range from a filthy air filter to a defective blower motor or a malfunctioning fan control board. 

Moisture/Water Buildup in Unusual Areas

Your system is designed to be always dry; failure to do so may result in mold and mildew development in both your system and home. If you discover a leak, this suggests that the system may have a malfunctioning or blocked condensate drain, and it is in your best interest to solve this problem as soon as possible.

Strange Noises

Every mechanism has been designed to be very quiet. Noises that are louder than usual during operation, such as metallic screaming, grinding, or slamming, indicate an internal problem (broken components, loose belts, debris). If you hear strange sounds coming from your air conditioner, it may need to be evaluated by a professional from an air conditioning company.

Unusual Smells

If your air conditioner is creating strange odors, you should get it fixed as soon as possible. If the odor is very strong, it might indicate a problem with the filter inside the device.

“Odd smells may sometimes be attributable to issues with the ventilation system, the filter, or the condensing unit itself,” according to, (, an HVAC repair company near Dallas, TX. Their website offers many interesting guidelines on how to fix many problems with your air conditioner, and when to call a professional.

Problems with the Thermostat

The thermostat is the “brain” of your air conditioning system. It communicates your home’s cooling requirements to the AC system while also continually monitoring the environment and providing new instructions to the system.

This component may have some issues, so shutting off your thermostat and then turning it back on after a few minutes is a smart approach to see whether it is working properly. If the problem keeps happening, you should call a heating, ventilation, and air conditioning (HVAC) expert to check your thermostat and the whole system. 

High Cooling Costs

Most of the time, the amount of energy used in the house is highest when the air conditioner is running. If it worked flawlessly the previous season, but your energy bills have significantly increased this year, this is a strong indication that you should have your unit inspected, as it indicates that something is wrong with it. 

AC Turns on and off

Your air conditioner is most likely experiencing short cycling, which is a common problem that affects most households, especially during the summer when it turns on and off quickly.

Short cycling may be caused by several factors, including thermostat malfunctions, clogged air filters, refrigerant leaks, failing compressors, and defective electrical systems. Because short cycling can cause your energy bill to go up a lot, you should talk to an expert as soon as possible to find out what’s causing the problem and how to fix it.

The System Does Not Turn on

If setting the thermostat does not turn on your AC system, this is a strong sign that you have to call a professional repair company. For instance, if you switch the system to “cool,” and the fan operates but the outside unit doesn’t, it’s an indicator that your system isn’t starting up properly and has to be repaired.


In general, proper care and maintenance are a must to ensure that your air conditioner will perform without flaws when you need it the most. If you want the air conditioning unit to last as long as possible, you must keep it clean and do routine maintenance on it.
