AC Not Working?

Is Your AC Not Working Properly?

Let’s face it AC problems can be frustrating especially if you’re living with young children or an elderly family member. Before you start reading this blog post remember that there are several common issues with your AC system that hiring a professional is the best idea (and we’re not just saying that because we are a professional).  Review the following common causes of serious AC problems below and then you may choose to consult with a professional technician in order to address most of these problems.


Common Causes of Air Conditioner Problems

  • Wiring problems: Problems with the wiring in your unit or the wiring that runs from your unit to an outlet are one of the leading causes of air conditioner breakdowns. It’s a good idea to check the breakers in your house’s power box and adjacent outlets to ensure that the problem lies with the air conditioner and not other electrical components.

  • Icy buildup: If ice collects of your condenser coils or other portions of your unit, the AC may not turn on or may not cool air efficiently. The unit must be dethawed and all ice must be removed before it will operate properly.

  • Faulty motors: In most cases, your A/C unit will shut down entirely if its motor is faulty. You will need to decide if your motor can be repaired or if it must be replaced.

  • Faulty compressors: Problems with your compressor may cause your A/C unit to shut down. Keeping your compressor clean can help to prevent these problems.

  • Dirty evaporators, filters or condenser: Dirt and buildup in an A/C system is one of the leading causes of breakdowns. Be sure to have your unit serviced on a regular basis to prevent these problems. If your unit has filters, they should be changed according to the manufacturer’s schedule.

  • Refrigerant shortages: If your A/C unit doesn’t have enough refrigerant, it may not turn on or may not operate correctly. You should always have a professional technician check refrigerant levels and change these fluids.

  • Faulty thermostats: Be sure to eliminate the possibility that your unit won’t turn on because your thermostat is faulty. If you suspect that your thermostat is bad, try turning the A/C on from the main unit. If the unit will turn on manually, you are likely suffering from a thermostat problem.

Resolving Air Conditioner Problems: Repair or Replace?

How do you fix an AC unit that won’t start? If your air conditioner simply won’t turn on, you’ll need to decide if you should repair or replace the unit. Unfortunately units that are usually 12 years old should generally be replaced with more efficient units. If the AC cuts on and off before your home is cool or your hvac unit won’t shut off, you may need a repair. However, you should carefully evaluate repair costs before making a final decision. A common rule of thumb is if repairs will cost more than 50 percent of your unit’s overall value, it is better to replace the unit.
