If your furnace is not working properly, there are certain repairs and maintenance jobs you can do yourself. An experienced do-it-yourselfer can find the information needed to clean clogged filters, adjust the flame sensor or replace the igniter with no trouble. However, when it comes to some parts or problems, you should always leave the repair to the professionals. A lack of proper equipment or a simple mistake could result in an undetected gas leak or more damage to the unit.
Replacing the Inducer Fan
The inducer fan pulls air into the heat exchanger to clear out any gases that are lingering from the previous heating cycle. The fan starts a few seconds before the heat exchanger. You will usually hear it kick on and then hear the woosh of the heat exchanger turning on. It looks like replacing this part would be simple, and can be, if you have the proper sealants and know how to use them. You should also have a carbon monoxide tester available to make sure everything is sealed properly. Even a small leak can have carbon monoxide escaping through the air vents and into your home. This could be deadly.
Replacing a Gas Valve
There is little doubt you could unscrew the old gas valve and screw the new on in place. However, this does not mean it is going to work properly or efficiently. If you really want to replace it yourself, go ahead, but you are still going toned to have the service technician come out to calibrate it. Every furnace is a bit different in how it should be calibrated. In addition, the gas pressure on the line coming into your home must be taken into consideration. You could skip the calibration part, but it is going to cost you more money. The heat exchanger will burn out and there will be a buildup of soot in the system. This will mean you need to have expensive parts, or the whole unit replaced, cause your gas bill to increase and may start a fire in the system.
The smart do-it-yourselfer understands that there are going to be times when the professionals need to be called in. Go ahead and take care of the simple repairs yourself. When it involves a part that handles the gas coming into or leaving your home, a pro should always be called to make sure nothing is getting into your home that could harm your family or staying in the unit to destroy your furnace.
