Indicators That Your AC System Is Malfunctioning

Homeowners are advised to keep a close eye on their AC systems. By doing so, you'll know when your AC system acts up. Remember, it's crucial that you point out problems early before they escalate. As long as you inform the technician earlier, the repairs will be easy, and you won't be charged a lot.

Here are the indicators you ought to look for.

Broken Thermostat 

HVAC units can't function if the thermostat is broken. This vital component acts as the command center of your air conditioning unit. Your AC system has to take instructions from the thermostat to function. Otherwise, the unit won't know when and how long it should run. Luckily, thermostats rarely malfunction. So, before inviting a technician, check whether the thermostat has run out of batteries.

Noisy Operation

You shouldn't have a noisy air conditioner unless one of the components needs repair. In most cases, your unit will make grinding, squealing, or scraping sounds when there is a problem with the belt or other internal components. The noises might get louder if you fail to call an HVAC technician to diagnose and repair the issue.

High Utility Bills

Most homes have a rough estimate of how much money they spend on electrical bills. Therefore, your bills should remain constant unless you have introduced new appliances. If your electrical company starts sending huge electrical bills, you should get the air conditioning system checked. It's probably struggling to cool your home and needs a little tune-up. 

Warm Air

Everyone expects their air conditioners to cool their home during summer. So, running your AC unit is unnecessary if it blows warm air instead of cool air. Unfortunately, you need your AC system running to keep your space comfortable. That said, you need an air conditioning system repair service if the unit keeps blowing warm air. AC units blow hot air when the refrigerant levels are low or when there is a refrigerant leak. Other possible reasons are:

  • The thermostat is set incorrectly
  • Your outdoor unit has lost power
  • Dirty evaporator coils

AC Unit Runs Constantly

Air conditioners aren't designed to run non-stop. They should automatically shut down once the desired temperature has been achieved. So, your AC system running non-stop means that it's struggling to cool or warm your house. Alternatively, you might be dealing with an issue of restricted airflow, dirty air filters, a faulty thermostat, poor insulation, air leaks, or your unit is just old. Whichever the case, you need to hire an HVAC technician to establish the reason why your air conditioner runs constantly.

If you notice any of these signs, get in touch with an AC repair service.
