Every winter, you rely on your furnace to keep you warm during those cold days and nights. Imagine then, the heartache of turning on your furnace to either find out that it's not blowing hot air, or not blowing any air at all. While it may be a problem with your entire HVAC system, you may be able to isolate it to just your furnace unit. Below are some of the problems that occur most frequently with furnaces. If any of them sound familiar, hire a company to perform basic furnace repair as soon as possible so that you can get back to enjoying your home.
Pilot Light is Out
Your pilot light is responsible for providing the initial energy source that your unit needs to create the hot air that blows through your vents. It can go out for a variety of reasons and is usually pretty easy to turn back on, but that doesn't mean you should attempt it yourself. Furnaces can be fickle beasts and the process can change from unit to unit, so it's best to leave it in the hands of someone who handles residential heating repair.
Reduced Hot Air
If your furnace is blowing hot air, but just not enough of it, there could be a couple of different issues. First, your vents may be clogged due to grime and muck that inevitably collects inside the ductwork, or you could just have ducts that are rated as too small for your house. This second problem generally happens when additions are performed on the house, such as a new bedroom or theater unit. The best thing to do in this situation is to hire an HVAC contractor to replace or repair some of the vents to open the space back up again.
Blower Constantly Running
The temperature in your house is controlled by your thermostat, which in turn, affects the limit switch to your furnace. When the desired temperature is reached, the limit switch tells the unit to stop producing so much hot air; if it's faulty for whatever reason, it'll need to be replaced. Your heater will continue to spit out hot air inside your house until you manually shut it off, but it can also create excessive wear and tear on your unit and cause it to be replaced sooner rather than later. It's one of the most basic furnace repairs a technician can perform, but it's one that absolutely needs to be done by a professional.
