Do You Need Heating Repair Service?

If you notice your central heater is exhibiting off smells, strange noises, declining performance or tripped circuit breakers, you should call for heater repair service immediately. Hidden problems are hard to find and can include drafts, higher utility costs and cold spots.

When you call our fully-staffed service department, we’ll reduce your stress level and help you save time and money. If your heater is running in a weakened condition, the faulty parts place a lot more stress on other vital components.

When the problem isn’t addressed, a minor issue can quickly become a major expense. No matter what heating problem you may have, it’s comforting to know one of our skilled technicians can quickly diagnose the unit and make the necessary repairs.

The Heating Repair Process

At William G Day Company, we know how frustrating it is when your heat pump or furnace breaks down when it’s cold outside. A bad situation can get a whole lot worse if your service provider can’t arrange an appointment promptly.

We’ve developed a large service department, so we’re always ready to fix your heating unit, regardless of how busy we are. When you call us for service, you’ll get a fast response, and we’ll try to schedule an appointment that accommodates your schedule.

Central heating systems can develop a wide variety of problems that are usually exposed during severe weather:


  • Cracked heat exchanger
  • Clogged filters
  • Failed relays
  • Bad ignition systems
  • Blocked b-vent systems
  • Faulty burners

Heat Pumps

  • Compressor failure
  • Low refrigerant
  • Clogged condensate drains
  • Burned out contactors
  • Motor problems

A cracked heat exchanger in a furnace can be dangerous, so we recommend purchasing an annual maintenance agreement to ensure the equipment remains safe and continues to operate according to the manufacturer’s guidelines. Installing a carbon monoxide detector provides an added level of protection for your family.

If you need a heat pump or furnace repair, our NATE-certified technicians have the experience and skill to restore your unit to full working order. We know how to repair virtually every brand of equipment, and we offer 24/7 service for emergencies.
