Do you need our help?

Inevitably during those first hot days of summers one of our techs arrive on an emergency AC repair call only to find that the problem was something the owner could have easily resolved. Perhaps you can save stress, time, and money by checking these things before you call:

Is the power 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 in or adjacent to your mechanical space that may have a RED cover-plate.
  • Check the two circuit breakers for your system to ensure that each breaker is "ON" for your indoor furnace or air handler, and your outdoor condenser.
  • Check your outdoor unit disconnect: The disconnect is typically a box on the wall near the AC outdoor unit. Make sure that it is set to "ON."

Is your T-Stat set for cooling?

  • If your thermostat has batteries, change them now and try again.
  • Make sure your thermostat is set to "ON", is set to "COOL", and the desired room temperature is set lower than the current ambient temperature.

How is your indoor airflow?

If your AC system has been or is currently running, but it does not seem to be cooling properly, you might have a problem with your indoor airflow. Check to see if your indoor coil and refrigerant lines are cover with heavy frost or ice. If so check:

  • 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?
  • If it turns out you had and airflow restriction and you have resolved that issue but your coil is still ice covered, set your system to "FAN" only unit the ice melts.

Other Issues

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 Air Conditioning Repair

We are locally owned and our staff has decades of experience dealing with the air conditioning problems of Darby, PA area home and business owners. Air conditioning problems are often caused by improper installation or maintenance. Common air conditioning problems that you'll need our help with include:

Installation Issues

Improper Equipment Sizing: Bigger isn't better when it comes to cooling equipment. Rooms are too hot or too cold. System short cycling without proper dehumidification.

While this is a difficult problem to solve, we can offer way to mitigate this rookie mistake.

Improper Ductwork: If duct systems are not properly sized areas can be overcooled leaving other rooms that are too hot. Air conditioning ductwork really needs to be insulted to prevent condensation and energy loss, and properly sealed with mastic or tape.

Condensate Problems: Water condenses on your indoor coil during operation. This water, or condensate, needs to be properly removed either by a gravity drain or a condensate pump. Water accumulating below your air handler or in concealed spaces indicates a problem with your condensate removal system, and failure to address this issue will cause equipment failures and property damage over time.

Refrigerant Leaks: Air conditioning is not turning on or not cooling. Properly installed AC systems should never loss refrigerant. If your system has lost refrigerant it is likely caused by poor installation, or mechanical damage to the refrigerant piping.

Thermostat not working properly: Improper system programming, battery issues or wiring problems like a broken conductor or loose connection.

Deferred Maintenance Issues

Dirty Filters, Obstructed Indoor Coil, or Obstructed Grill or Registers: This is an extremely common problem. Indoor coil or refrigerant lines covered with heavy frost or ice.

Obstructed or Clogged Outdoor Coils: This is caused by failure to clean filters over time, or operating the system without filters, and results in lower system capacity and inefficient operation.

Age Related Component Failures

Breaker Trips: Breaker to the outdoor has unit tripped more than once potentially indicating improper wiring or potential compressor, fan motor, 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.

On every service call, we thoroughly evaluate your air conditioning system and prepare complete job estimate before we start any corrective work so you never are charged for something you aren't expecting.

If your air conditioning system is more than 12 years old and needs significant or costly repairs, we'll let you know. We may also suggest upgrading to a new more efficient air conditioning system.
