Greater Jacksonville area gas furnace repair

Though it may not happen often, when temperatures take a dip in northeast Florida, you rely on your gas heater to work properly. But if your system fails you at the most inconvenient time, you can trust the experts at Donovan to arrive within minutes to repair your home furnace.

How a gas furnace can break

In most homes, a furnace is the primary source of central heat, and it works by pumping hot air into rooms. The most common type of furnace is gas-powered and heats air, distributing it throughout the home via vents and ducts.

Though it rarely happens often, a gas furnace can malfunction for a number of reasons, including:

  1. The control board can become damaged, which prevents the furnace from reading the thermostat.
  2. The thermostat may need to be cleaned. The batteries in the thermostat can also go bad
  3. The furnace could be acting up because of faulty wiring or a blown fuse.
  4. The air filter in your furnace’s ventilation system may be dirty or blocked.
  5. The evaporator coil may be plugged, especially if you haven’t changed the filter in a while.
  6. The igniter may have deteriorated with age, may have an incompatible component, or it could have a bad limiter switch.
  7. The gas valve may not be opening and closing properly to allow the flow of gas to the pilot light and burners.
  8. The furnace blower may have malfunctioned, so it is not blowing enough warm air.

What do I do next?

A non-working gas furnace is not just an inconvenience for your home and family—it could be a sign of a more serious safety issue. You should always call a professional to inspect and repair your gas furnace when it’s not functioning properly.
