When your thermostat senses that heat is needed in your home, it signals the furnace to turn on. Combustion of the gas and hot products warm the metal of the heat exchanger, switching on the timer for the blower or circulating fan. After a few minutes, this fan begins to circulate air across the exterior of the heat exchanger, allowing the furnace to re-circulate this air throughout your home. As you can see, there are many components of a working furnace, making heating repair essential to the longevity and performance of your HVAC system. Once the winter months arrive, your heating system needs to be in peak condition, so it's important to examine and evaluate your furnace long before it fails. But what are the signs and symptoms to look for? Age Furnaces don't last forever, so the older your appliance gets, the more susceptible it will be to problems and repairs. Most models operate reliably for about 20 to 30 years. So, if your unit is 15 years old or more, you should probably begin to consider furnace replacement options. Bills If your heating and cooling bills seem to be increasing despite your usage staying the same, your HVAC system is likely to blame. Poor circulating fans or clogged ducts may not be allowing the hot air to reach your rooms, forcing the furnace to work even harder than usual with no result. Uneven Heating If some of the rooms in your house seem to heat rapidly, while others remain cold, it's probably time to consider heating repair. This indicates an issue with the blowing mechanism in your furnace, which will either need to be repaired, or replaced altogether. Strange Noises Pay attention the noises your furnace typically makes. Any strange humming, rattling, or buzzing can indicate a problem with the system. Also pay attention if your furnace seems louder than usual. This can indicate something blocking the blowing mechanism, or clogging the burners, which can lead to permanent damage. Humidity Problems This is a subtle problem that can have damaging repercussions to your home if not attended to. Pay attention to the level of humidity around your furnace, checking the walls and surrounding furniture for signs of sweating. This means the system is not operating effectively, and can cause paint to begin to peel or chip, and wooden furniture may warp or even become stained. Rust Always check your appliance for signs of corrosion or rust. This is another serious sign of wear on your furnace, and can lead to cracks and other damage to its components. If you suspect there may be something wrong with your HVAC system, or just want schedule a checkup to prevent any future problems, make an appointment with a heating repair specialist in your area. A good contractor will come out to your home and evaluate the situation, providing you with quality repairs, or an estimate for replacement. Don't wait until next winter to have your furnace evaluated. It's always better to prevent a problem than to live with freezing temperatures while it is being repaired or replaced.
