When Should I Repair my AC unit?

ou can fix any problem with your AC unit, but the overall cost may not be worth the repair cost. Different parts can break down simultaneously if the unit is older than 10 years. In addition, more expensive components such as the evaporator coil, compressor replacements, and refrigerant leaks can quickly add up, making it more cost-effective just to replace the entire system. If your unit meets any of these conditions, consider a replacement today.

  • Your air conditioner is under 10 years old.
  • Your unit needs occasional repairs, none of which are too costly.
  • The broken parts are regular wear items.
  • Your energy costs are rising.
  • There are strange noises coming from your AC unit.

Signs You Need Air Conditioning Repair Services

Sometimes an air conditioner will give out with no warning or produce subtle signs that there is a problem. Call a professional if you notice any of the following:

  • The unit is not turning on.
  • Airflow is warm, not cool.
  • Rooms are experiencing uneven cooling.
  • The temperature on the thermostat doesn’t match the indoor environment.
  • The air conditioner is constantly kicking on or never turns off.
  • There are musty or burning smells blowing through the vents.
  • There are loud banging, screeching, or knocking noises coming from the unit.
  • The unit is leaking coolant and/or water.

When you hear strange noises, turn off your unit immediately and contact a professional; otherwise, running your unit with a loose or broken part can cause further damage to the unit. Musty smells can be a sign of bacteria growth that could cause allergy symptoms, so contact a professional to remove smells, bacteria, and other allergens from your ducts. The sooner problems are dealt with, the greater the life expectancy of your unit, so be sure to have a seasoned professional like Fix-it 24/7 check your system periodically to ensure your unit’s and your home’s health.
