How to Tell If Your Furnace Needs Repair
Having a furnace is a great way to heat your home. However, when the furnace is not working properly, it can cause a lot of problems. It may be time to have your furnace repaired. However, before you call a repair company, it’s important to consider whether or not the problem can be fixed on your own.
A furnace is a complicated piece of machinery that has many mechanical parts. When you have an issue with your furnace, it’s important to have a specialized technician diagnose your problem. A professional will also be able to help you determine if your furnace needs to be replaced. A replacement may not be the best option, and a repair can often cost less than buying a new furnace.
If your furnace is leaking gas, it can be a health hazard. If you notice a sour smell around your furnace, it’s a good idea to turn off the power to the furnace and call a repair service. A furnace leak can be a dangerous situation, so it’s best to leave your home immediately. A gas leak may lead to other problems that require professional help.
Another problem that can cause your furnace to malfunction is a dirty air filter. If your filter is dirty, your furnace will have to work harder to push air through the system, which may cause it to run more often. It may also lead to uneven heating. If you notice that the furnace is working more than it should, it’s time to get a new filter.
Another common problem is a failure of the flame sensor. This sensor is responsible for inspecting the furnace for a flame, and if it fails to do so, it triggers the safety features to shut the furnace down. The problem usually lies in the maintenance of the sensor. If you don’t clean the sensor rod regularly, byproducts and dust will accumulate. This prevents the sensor from working properly, which can lead to more serious problems.
Other common problems with your furnace are rapid cycling and a dirty thermostat. Rapid cycling is when the furnace cycles on and off quickly, and a dirty thermostat can cause your furnace to run continuously. If you notice that the furnace cycles on and off quickly, or if the temperature in your house drops quickly, you may need to have your furnace replaced.
Rapid cycling may be caused by a failing thermostat, a faulty blower motor, or a defective transformer. A transformer costs about $20-40, and a replacement may cost a bit more. If your furnace has a transformer, it’s important to have it checked by a professional to ensure that it is working properly.
Thermostats are programmable, and should be set to the correct time and temperature. If you have a timer, make sure it’s set to “Heat” or “Heat” instead of “Auto.” Some thermostats also use batteries, and they should be replaced.
If your furnace is older than fifteen years, it may no longer be as efficient. It may also have trouble starting. This is often the result of a problem with the ignition system. If you have a furnace that’s older, it’s important to have it repaired to prevent your energy bills from skyrocketing.
