Your AC Keeps Turning On and Off

The occurrence known as short cycling is often caused by similar factors that prevent an air conditioner from shutting off. To address this, consider replacing the air filter and ensuring that vents and registers are unobstructed. If the issue persists, it may be related to electrical problems or dirty condenser coils, in which case, it’s best to seek professional assistance. 

Your AC Blows Warm Air

To start, the first step is to change your air filter if it’s dirty. Ensure that the MERV rating of the filter is suitable for your system; typically, it should not exceed 13, but for some AC units, the limit may be lower. Verify your thermostat settings to see if it’s set to “auto” rather than “fan.” If it’s not on auto, the fan might circulate warm air during cooling cycles. Other issues like frozen evaporator coils, leaky ductwork, refrigerant leaks, and an aging system may necessitate professional repair or replacement. Schedule Now

Your AC Is Producing Noise

  • Rattling: Loud, metallic rattling may indicate detached or broken parts in the AC unit. It is advisable to have a professional inspect and replace any damaged components.
  • Buzzing: Quiet rattling or buzzing could be due to debris lodged in the outside AC unit. Check the compressor unit and remove any obstructions like branches or leaves.
  • Humming: Vibrations can loosen parts over time, causing a humming sound during operation. Homeowners can try tightening the fan blades and refrigerant piping. If the noise persists, seek professional assistance.

  • Whistling: A loud, high-pitched whistle often indicates a refrigerant leak. If you hear a whistle resembling a scream, turn off the AC immediately and contact emergency services.Schedule Now

Your Air Conditioner Won’t Shut Off

  • Dirt and grime can impede the AC fan blades, forcing the system to work harder to cool. Gently clean the fan with a vinegar and water solution to remove stubborn dirt.
  • Some issues require professional attention. Electrical problems may necessitate an electrician to repair the wiring or an AC unit replacement.

Your Air Conditioner Drain Is Backed Up

Your air conditioner produces water as it runs—even in the dry heat of Las Vegas. It should drain out of a hose in a central outdoor unit or collect in a drain pan on a window AC. However, drainage can sometimes get clogged, backing water up into the AC. Clear debris from the drainage hole of your outdoor compressor and make sure to regularly empty the drain pan on your window unit.

If your air conditioner has taken water damage from a backed-up drain or drain pan, call an expert for repairs. Schedule Now
