When your furnace stops working in cold weather, you need the problem fixed immediately, not days later. In this article, we focus on furnace and heating problems that have fast and easy repairs. Before you conclude you need a new unit, or set aside money for expensive repairs, ask a technician if your heating issue stems from one of the following fast furnace repair issues.
1. Extinguished Pilot Light
If you heat with gas, a pilot light is required to ignite the gas jets that produce your home’s heat. Without it, your gas furnace won’t kick on. Relighting a pilot light is as simple as using a fireplace match to reach it. A technician can fix the problem within seconds, or you could fix it yourself by reading your furnace’s maintenance manual.
2. Dirty Air Filter
Air filters are designed to remove dust, pollen, and other irritants from the air as it passes through a furnace’s blower unit. Therefore, the debris it collects can eventually prevent air from reaching your blower vents, leading to decreased heating capacity. If you notice the force of the air coming from your vents is decreasing, refer to your furnace’s manual to locate its filter. It may be the cause of your heating problem.
3. Leaky Ductwork
Over time, the seals on ductwork can develop leaks that let warm air escape into floors and walls instead of delivering it to living areas. As a result, homeowners with leaky ductwork often crank up their thermostat to reach a desired temperature, creating an enormous electric bill. If your forced air system is delivering less heat, don’t assume you need a new unit. Have your ductwork checked.
4. Dirty Air Conditioning (AC) Coil
If your furnace’s AC coil becomes clogged, it may cause your furnace to kick off only a few minutes after it kicks on. A technician can clean your AC coil in a few minutes, or you can do the job yourself by referring to your furnace’s maintenance manual and/or doing an online search for the AC coil cleaning process.
5. Blown Fuse
A blown fuse isn’t a heating problem, but it could prevent your unit from working. If you have a traditional fuse box, check it to see if a fuse has blown, and replace it if it has. If you have a switch box instead of a fuse box, check to see if a switch is tripped, and switch it back if it has.
6. Thermostat Malfunction
If your thermostat is malfunctioning, it could lead to your unit producing intermittent heat, or no heat at all. If you aren’t experienced in electronic parts replacement, it’s best to let heating contractors replace your faulty thermostat, a process that should take less than 1 hour.
