Fixing the problems of your central heating system on your own is generally ill-advised. HVAC repairs are highly technical and hazardous. But then again, minor issues don’t always require professional assistance.
Like basic air conditioner issues, simple furnace problems are safe enough for average troubleshooters to handle. In Dave’s Heat & Air’s book, here are the situations where you can try to get your heating equipment running on your own:
Unit Is Producing Cold Air
It may seem uncharacteristic for your furnace to blow cold air instead of hot, but it’s not uncommon. Usually, it’s just a case of an incorrect thermostat setting. Make sure the temperature is right, and the fan is set to “auto” rather than “on”.
If your thermostat isn’t the culprit, it could be the air filter. Enough dirt accumulation can restrict the airflow, compromising your furnace’s performance. Clean or even replace it before trying again. If it still doesn’t do the trick, your unit might be running low on fuel.
Unit Has No Light
Seeing no pilot light in your new equipment isn’t a reason to call a 24-hour AC company or furnace technician. Unlike old-fashioned units, modern, high-efficiency products are equipped with an electronic ignition and have a flame system that prevents the fuel from flowing when off.
Unit Doesn’t Turn Off
If your fan is already on “auto” mode, only two things could be to blame: a broken thermostat or a faulty blower. You may be able to examine the wiring of a manual thermostat and perform a reset to get it working again. However, the digital one can be too complex for the layman. But if the issue isn’t the thermostat, call in a professional for further investigation.
Unit Heats Only Certain Areas
This issue is typically solvable with air-filter replacement. If it persists, your furnace might be struggling to distribute heat because of leaky ducts.
Unit Releasing a Burnt Smell
It’s always wise to seek emergency air conditioner service or furnace repair when your HVAC unit smells strange. If you can’t remember the last time you changed the air filter, try replacing the existing one first. If the odor doesn’t go away, unplug the unit until a qualified technician arrives.
