Check These Things Before You Call Us

In the early summer more than a few of our emergency AC repair calls turn out to be a problem that could have been resolved by the owner. Perhaps you can save stress, time, and money by checking these things before you call:

Check System Power

  • Check you circuit breaker panel to ensure that your heating system breaker is "ON".
  • Check your indoor furnace or air handler system switch. Make sure your "SYSTEM SWITCH" is set to "ON". This switch is typically a traditional toggle switch that may have a RED cover-plate.

Thermostat Settings

  • Make sure your thermostat is "ON", is set to "COOL", and the desired room temperature is set lower than the current ambient temperature.

Indoor Airflow Issues

  • Is your furnace or air handler filter clean? Change your furnace filter and re-start your system.
  • Check your duct system inlets and outlets. Are almost all open and clear of obstructions?

Other Issues

  • If you thermostat or the system power was off, after turning the system on give it a few minutes; many AC systems have a time-delay function on start-up.
  • If your system is blowing cool air, but not cooling as well as it should, check your outdoor unit to ensure there is nothing blocking airflow through the outdoor coil. PLEASE NOTE: Be very careful not to damage the fines on your outdoor coil and call us if you need help!

Prompt Professional AC Repair

Air conditioning problems are often caused by improper installation or maintenance. Common air conditioning problems that you'll need professional help with include:

Installation Problems

  • Improper Equipment Sizing: rooms are too hot or too cold. System short cycling without proper dehumidification.
  • Improper Ductwork: If duct systems are not properly sized areas can be overcooled leaving other rooms that are too hot.
  • Condensate Problems: Water accumulating below your air handler
  • Refrigerant Leaks: Air conditioning is not turning on or not cooling
  • Thermostat not working properly: Improper programming or wiring problems

Deferred Maintenance Issues

  • Dirty Filters, Obstructed Indoor Coil, or Obstructed Grill or Registers: Indoor coil or refrigerant lines covered with heavy frost or ice.
  • Obstructed or Clogged Outdoor Coils: Low system capacity and not cooling properly.

Age Retalated Component Failures

  • Breaker Trips: Breaker to the outdoor has unit tripped more than once potentially indicating improper wiring or potential compressor or capacitor issues.
  • Fan or Blower Motors: A persistent vibration or odd noise with the outdoor or indoor unit
  • Unusual Odors: Near the outdoor unit, or coming from the ductwork outlets.
