Obvious signs you need a heat pump repair

Some Clues that your system isn't operating correctly

If you think you may have a problem related to cooling or heating your home, check out these common symptoms of a Heat pump system that may not be functioning properly. Be sure to call Dan’s air for local cooling or heating repair at 301-712-9530.

When your System is running all the time can have several causes including being low on refrigerant (freon). You may notice at the thermostat that your auxiliary heat (Emergency heat) indicator is on more than normal. Its important to have your freon level tested by a qualified technician and to find the source of the leak if indeed it is low. Continuing to run the system could cause damage to the compressor.

Clogged condensate drains are a common cause of water leaking from your air conditioner. Freezing coils during operation could also cause water leaking around the furnace from the evaporator coil at the indoor unit. We recommend clearing the condensate drain line before the start of every season.

A buzzing noise at the Outside unit is very common when there is an electrical issue with the compressor. 

A loud noise coming from the air handler fan can be an indication of a bad blower motor. 

The back up heating elements for your heat pump use much more electricity than the heat pump itself. A high energy bill can be an indication that you need service.

Some frost on the outside heat pump is normal. There is a defrost cycle that comes on periodically to thaw the ice from the outdoor coil. If there is always ice and the defrost doesn’t seem to be working,

Its no secret that Maryland has some extra hot summers. Our area is known also for having high humidity levels in the summer which causes our heat pump systems to work extra hard during the cooling season.  Luckily most breakdowns that occur are not that serious and are easily repaired.  Be sure to check out our other air conditioning services that we provide in your area.


Dan's Service Plan - Heat Pump Maintenance Plan

A great way to protect your Heating & Cooling System and ensure the safety of your family is with one of our HVAC Maintenance Plans from Dan’s Air.


Dan’s Plan Platinum is by far our most popular choice as it includes Cleaning and Diagnostic Services that usually should be performed at each service visit. Choose this plan if your system is more than a couple of years old.

Our Gold Heating and Cooling Service Plan is a more economical choice that focuses mainly on Heating and Cooling Inspection and system performance. Choose this plan if you have recently replaced your system and it isn’t old enough to need cleaning. If you just want a proper heating and cooling assessment, this may the choice for you.

Benefits include keeping your family safe, lower utility costs, longer life of your cooling and heating system, and avoid excessive costs on repairs. Also save money on products and services as well as enjoying priority service. Be sure to compare our plans.
