1. A Sudden loss of heat: The first thought you have when your furnace suddenly stops is a power outage or surge. At least, that's what I hope happens when my furnace stops! If you haven’t lost power, check your fuse box to make sure that you still have power going to the furnace. A malfunctioning pilot light or ignition system could also be the issue. If that's the case, you definitely need a professional like South Nashville Heating and Cooling because this is not a job for an amateur - no matter how handy you are at fixing things around the house!
2. Cycling heat: A clogged dirty filter or blower can cause inadequate air flow. This can cause your furnace to click on and off frequently at it shuts off after heating up too quickly. Another problem could be a faulty thermostat can also cause this issue. If you do not know your furnace components, have home heating experts inspect your furnace and resolve the issue of unwanted heat cycling.
3. Inconsistent room temperatures: These inconsistent room temps could be caused by 2 things: Draft issues and/or unbalanced air flow.
If your house is cold despite a continuously running furnace, a draft might be the problem. Leaking windows, drafty doors, and poor or damaged insulation are major heat losses. Check the most obvious places. A professional energy audit from your local utility provider can also help.
Another source of inconsistent room temperatures can be unbalanced air flow. Manually adjusting the vents may resolve this problem, however, air flow problems are often caused by dirty coils or filters.
Make sure to schedule routine air filter inspections with an HVAC professional like South Nashville Heating and Cooling. You can also prevent this issue by having a professional provide routine vacuuming of your registers and returns.
4. Carbon monoxide: Carbon monoxide is the most serious issue and a major risk for home owners. It is odorless, colorless and tasteless, giving it the nickname of “silent killer.” If your gas furnace is 10 to 15 years old, there is a higher risk of having a rusted heat exchanger. Tiny cracks in the heat exchange can leak carbon monoxide. Sometimes, these cracks can be very small or difficult to find.
If you have an older gas furnace, installing a carbon monoxide detector is a smart, safe idea. Be certain to have a professional inspect your HVAC for potential carbon monoxide leaks whenever you have these experts at your home for maintenance, repairs, installations or other work.
