Common Repairs for Heating Systems


There are several different types of central heating systems for homes: furnaces, boilers, heat pumps, and ductless mini splits are among the most common, and our technicians work on all of them. When you’ve got trouble with heating your home, you can rely on us for heating repair in Egg Harbor Township, NJ

To give you a better idea of the different types of heating systems and the sort of work we do, we’re going to look at several of the most common repairs we perform on each of these different heaters.


Most homes have either a gas-powered furnace or an electric furnace, and repairs will differ between them. Both often need service to repair the blower motor that moves air around the heating elements/heat exchanger. 

Common repairs we do for gas furnaces involve issues with gas flow and gas safety. A gas furnace can sometimes have difficulty igniting its burners, which may require us to replace the ignition system, clean the burner, or repair one of the safety mechanisms like the flame sensor. Any repairs done to a gas furnace need to be executed with special precision and caution to ensure safety—this is why you must never trust gas furnace repairs to anyone who isn’t certified for the job.

With electric furnaces, the most common issue we encounter is with burnt-out heating elements and the sequencer that’s designed to activate the heating elements one at a time. We often need to make repairs to the control board.


Fixing leaks is one of the repairs we often need to tackle with boilers: homeowners are quick to notice when a boiler is leaking, and calling us right away is the best step. We frequently make repairs to boilers’ manifolds, which is responsible for distributing the hot water to the different terminal boilers. Boilers need occasional flushes to remove sediment that may build up inside them and mechanical repairs to fix their circulator pumps.

As with gas furnaces, gas boilers must have professional repair service to avoid severe safety hazards. 

Heat Pumps

Heat pumps are extremely similar to air conditioners, and they share many of the same repairs:

  • Sealing refrigerant leaks and recharging the lost refrigerant
  • Cleaning the refrigerant coils
  • Repairing or replacing motors
  • Fixing the control board
  • Repairing a hard-starting compressor

Heat pumps have a few unique repairs from air conditioners: replacing a broken reversing valve and fixing a faulty defrosting system. These are components not found in air conditioning systems. 

Ductless Mini Splits

These are types of heat pumps, so they have many of the same repair requirements we listed. In addition, our technicians have to deal with issues with the different wall-mounted units that make up a ductless mini split system. Leaking refrigerant or condensate moisture between one of these units can cause it to rip away from the wall. 

No matter the heating system your home has, you can put your full trust in our team to find what’s wrong with it and have it quickly back in working order.
