subject: Simple Furnace Repair Tips [print this page] When you think your furnace is in need of repair, there are some things you can check before you call to have a professional take a look. Just by checking these few things, you might save yourself a couple hundred dollars, kind of like giving yourself a bonus. And, if the repair does turn out to be a simple fix, you'll have learned the new skills to check your furnace, as well as having saved a considerable amount of cash.
First, check to be sure the furnace is on. Always check to be sure the thermostat is turned on to "heat" instead of "cool" or even off. Also, be sure to check which temperature the thermostat is set on. As simple as this fix may sound, many repairmen have fixed a furnace just by flipping the power switch. Then, try turning the thermostat to five degrees warmer than the room temperature to see if it kicks on.
Loose Wiring and Breakers
Check wires to ensure that none are broken, loose, or shorted out. Also look at the battery and see if it needs replacing due to old age. If you're in doubt, replace it. It's much easier to replace a battery than to have the furnace troubleshooted. Another important thing to check is circuit breakers. Be sure that none of them have been tripped, especially if there's been a recent power outage. Even with automatic switches or flips, some items will need to be restarted manually. On the breaker board, look for a furnace switch. One of the best things you can do to keep your furnace running in great condition is to be diligent about changing the filter on it. If a filter is clogged, it will often cause the furnace to shut off too soon and before the house is heated. Other times, the blower can still be churning out air, but no heat is supplied at the source. Therefore it is simply blowing out room temperature or even chilled air
Gas Heaters
Another obvious fix here, always be sure to check that the gas is on. Old furnaces, which require a pilot light, should also be checked to ensure the flame is lit. Then, it's a good idea to check a few maintenance issues, such as the flue. Sometimes birds will try to hide there for warmth, or accidentally fly into it. By making sure there is nothing in the flue, you rule out one more possible reason for furnace trouble. Also look for blocked drain lines, or leaky or blocked ducts that could compromise air flow. Then go outside and make sure leaves and debris are cleared away if you have a heat pump system. If you're still freezing and nothing is working, you may need to call a professional that specializes in furnaces.
Calling in the Big Guns
If your furnace still cannot be fixed, you may need to start shopping for some good furnace sales, which can be more prevalent in the spring and summer seasons. Soon, with the help of a new heater and its installation, you'll be warmed up again and enjoying your home instead of freezing in it.
