Check These Four Things Before You Call For Heat Pump Repair:

With each change of season, one of our service techs arrives on a repair call only to find that the problem was a simple one that could have been resolved by the owner. If you check out these things, you may find you won't need our help after all:

Furnace repair from LMH is a call away!
  • First, ensure that your entire heat pump system has power.
    • Make sure your "FURNACE SWITCH" is set to "ON". This switch is typically a traditional toggle switch that may have a RED cover-plate.
    • Check your circuit breaker on your electric panel for both you air handler / furnace, and your outdoor unit to ensure that neither of these breakers has tripped.
    • Check the electric disconnect that is typically mounted next to your outdoor unit to make sure that it is "ON".
  • Then check your thermostat.
    • For cooling make sure your thermostat is "ON", is set to "COOL", and the desired room temperature is set lower than the current ambient temperature.
    • For heating, verify that your thermostat is "ON", is set to "HEAT", and the desired room temperature is set higher than the current ambient temperature.
    • If your thermostat has a battery, change it now.
  • Now check for indoor airflow issues: Poor indoor airflow can cause serious performance 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?
    • In AC mode, is there a heavy accumulation of ice or frost on the refrigerant lines near the indoor coil? This can indicate improper airflow.
  • Other things to consider:
    • If your 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 (in cooling), but not cooling as well as it should, check your outdoor unit to ensure there is nothing blocking airflow through the outdoor coil. In heating mode, the same issue can occur: the blower is on, but the air coming from the registers in not warm enough. PLEASE NOTE: Be very careful not to damage the fines on your outdoor coil and call us if you need help!
    • Defrost: In heating, your outdoor unit has a defrost function. During defrost, the indoor blower pauses, and the outdoor unit operates in defrost mode to clear the outdoor coil of ice or frost. This can take up to 15 minutes to complete, so be patient.

24 /7 Professional Heat Pump Service

When you need the skills of a professional, we offer emergency heat pump repairs for both residential and commercial applications around the clock. Our top-rated, licensed and insured AC techs offer full heat pump service regardless of the brand. Heat pump heating or cooling problems are often caused by improper installation or maintenance. Common issues include:

  Installation Issues:

  • Improper Equipment Sizing:
    • If the system is undersized, in extreme weather interior temperatures will not be able to maintained.
    • More commonly, if a system is short cycling without proper dehumidification in cooling mode it is probably too big.
  • Improper Ductwork: If duct systems are not properly sized areas can be too cool leaving other rooms that are too hot.
  • Condensate Problems: Water accumulating below your air handler because of an improperly designed drain connection.
  • Outdoor unit icing problems: In heating mode, the outdoor unit should be free of snow or ice. If the outdoor unit accumulates ice or snow around it base it will cause capacity problems or system failures.
  • Refrigerant Leaks: Heat pump is not turning on or not cooling or heating properly.
  • Thermostat not working properly: Improper programming or wiring problems.
  • Deteriorated Performance Due to Deferred Maintenance:
    • Dirty Filters, Obstructed Indoor Coil, or Obstructed Grill or Registers: Indoor coil or refrigerant lines covered with heavy frost or ice during cooling often indicate inadequate airflow.
    • Obstructed or Clogged Outdoor Coils: Low system capacity and not cooling properly.
  • 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 failures.
    • 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.
