Common heating repairs Dilmak technicians perform

The key to successful repairs is having experience with the various makes and models of residential and commercial heating systems. With more than 20 years of experience in the heating repair business, our expert technicians have compiled a top 5 list of problems that may cause your furnace or heater to break down and cause uneven, excessive, intermittent or no heat at all:

  1. Bad thermostat.
  2. Faulty ignitor or pilot.
  3. Faulty air flow switch.
  4. Cracked heat exchanger, resulting in Carbon Monoxide poisoning throughout the residence home.
  5. Faulty Safety switches, resulting in the heater not to start or not to shut off properly.
  6. Dirty filters.
  7. Overall remedy is proper Air Conditioning and Heating Maintenance.
  8. Dilmak Services can offer service agreements to meet all customers needs.

Regular maintenance is key to extending the life of your heating unit

Each of these common issues can be resolved by a professional technician from Dilmak Services. We can accurately pinpoint the problem and provide a proper solution. Additionally, most of these problems can be avoided with our Dilmak Maintenance Program. You can also take some preventive steps to save yourself money and headaches associated with all repairs. If you have a forced air furnace, we strongly recommend switching filters monthly. We also recommend replacing your thermostat with a programmable digital model to make your system more efficient and provide you with lower heating bills. Ask us to take a look at your duct work to see if that is another way you can possibly save on your energy bills.
