In the winter, you rely on your HVAC system to keep your home comfortably warm. However, your home comfort can be jeopardized by a variety of wintertime heating system problems. Here are some common winter HVAC concerns and what you should do to resolve them:
If some rooms are too warm while others feel too chilly when your heating system is running, check that the louvers are open on all your registers first. Then, examine the furnace filter because a clogged filter can reduce the amount of warm air that’s delivered to each room. Other possible causes that will require a professional diagnosis are leaky, damaged ducts or unbalanced airflow through the HVAC system.
Not Enough Heat
If the heating system doesn’t seem to stay running long enough to adequately heat your home, you have a situation known as “short cycling.” Your HVAC technician can do some detective work to find out why it’s happening, which could be a poorly-located or faulty thermostat, under- or over-sized equipment, or a corroded flame sensor.
Sudden Loss of Heat
If your furnace or heat pump suddenly stops cycling on, it may just need a simple fix like replacing dead thermostat batteries or a badly-clogged air filter, which can severely reduce airflow so the furnace overheats and triggers the high limit safety switch. Your heat pump can shut down similarly if the outdoor unit is covered with ice or snow and can’t defrost on its own. If none of these issues seem to be the cause, call your HVAC pro to check for more serious problems.
Combustion Fume or Gas Odors
Both of these issues pose serious safety hazards, so contact your home heating contractor immediately, and head over to a neighbor’s house until the problem is solved. Backdrafting combustion fumes from an obstructed vent system can pump deadly carbon monoxide gas through your home, while leaking gas lines can cause dizziness, vomiting and even asphyxiation, or an explosion or house fire.
