Unless you are a licensed HVAC contractor, assessing and repairing your air conditioning system can be quite hazardous. You could risk exposing yourself to severe injuries or electrocution. Therefore, it is best to leave AC repairs to the experts no matter how much you know about the system. But how do you tell that you need to schedule an air conditioning repair service with the experts? Take a look at some common problems that show you need repair services.

1. Defective Blower Motor

If the AC fan doesn't start when you switch it on, you probably have a defective motor. The blower motor is responsible for driving air into the vents. When neglected, the motor could suffer wear and tear and dirt build-up that prevent fans from circulating air as usual, eventually causing the evaporator coil to freeze.

While blower motors are generally reliable, they can fail without proper maintenance and timely repairs, causing further problems. If you noticed issues such as warm air, inconsistent cooling, or grinding sounds, consider calling a contractor to fix the blower.

2. Defective Thermostat

A thermostat is designed to help you set the preferred temperatures on your AC with ease. A defective thermostat makes it hard for you to set your AC unit correctly. For example, you may notice that your house is colder than usual despite setting the temperatures right on the thermostat.

Test your thermostat by setting the lowest temperature and see if it starts running. If it doesn't, it is time you called the technician to help assess and fix the problem. You may also need to replace the thermostat.

3. Faulty Electrical Connections

Sometimes, air conditioners run for an unusually long period without turning off despite achieving the desired temperatures. If you experience this problem, check your thermostat to ensure it is working and then call the experts to repair the system.

If the problem tags along with burning smells, you could be looking at electrical issues in the system. The unit may fail to run completely, indicating faulty electrical issues. Leaving it unattended can cause fire hazards, frozen AC coils, and low indoor air quality. Therefore, you should let repair specialists diagnose the problem and provide a solution.

4. Leaky or Filthy Vents

The ductwork delivers air from your AC to various rooms. If you fail to schedule regular duct cleaning, there are high chances the ducts drive filthy and contaminated air into different rooms. Inspect the ductwork for leaky ducts, especially if you have noticed a sudden spike in your energy bills. As more air escapes into the walls, your AC has to work harder to achieve desired results. The harder it works, the more energy it consumes, which leads to high electricity bills.

Work with an AC technician to help you improve your system's performance if you come across any of the problems discussed above. Schedule an appointment with the AC repair technician to fix any issues and ensure your house is safe, cool, and comfortable.
