As the cold and windy winters of Dallas arrive, it’s time to gear up. Of course, the first step is to get our furnaces ready, keeping us warm throughout the season. But before you curl up inside your cozy house, you need to take a look at the furnace. For instance, is your furnace blowing cold air instead of warm?
7 Furnace Troubleshooting Tips
These minor issues can be a real pain on a short cold day. So, before you call a furnace service in Dallas, here are some quick troubleshooting tips to make things easier.
1. Thermostat Stopped Working
Since a thermostat controls your furnace’s air temperature, shutting down can cause the furnace to blow cold air.
If your thermostat has stopped working, get rid of it. Contact a professional furnace replacement in Dallas or consider upgrading to a smart thermostat for better control and comfort.
2. Broken Control Panel
If your furnace is suddenly blowing cold air, a broken electric panel might be the culprit. You can quickly resolve this issue by turning the switch off and on after a few minutes. However, if the problem continues, call a professional furnace repair.
3. Leaky Ductwork
Holes in ducts can cause heat energy to escape. In this way, the heated air doesn’t reach your rooms, thus remaining cold. Get your leaky ducts fixed or replaced (if required) by a professional heat pump service in Dallas.
4. Thermostat Fan Settings
If your furnace’s thermostat is set to “ON,” it causes the unit to run even with no heat cycle. Change your thermostat’s fan settings to “AUTO” instead of “ON.” This makes sure your furnace runs only during a heating cycle pushing out warm air.
5. The Pilot Flame Has Gone Out
If your furnace’s pilot flame goes out, there will be no combustion hence no heat. Relight your pilot flame in these simple steps:
- Turn off any power supply to the unit.
- Locate the pilot assembly and turn OFF the reset switch.
- Wait for 10 to 15 minutes so that excess gas can escape.
- Hold down the reset switch and use a lighter or match near the flame.
- Once the flame is lit, turn the reset switch ON.
- Turn back on the power supply.
6. Water Puddle Around The Unit
The condensate line removes excess moisture from the furnace. If it gets blocked, the excess water leaks out. Eventually, the system’s “overflow kill switch” turns off the unit to prevent water damage. The best way to resolve this query is to get the drain line cleaned and replaced by a furnace service in Dallas.
7. Dirty Air Filters
If your furnace’s air filters are full of gunk and debris, it might be simply blocking the airflow. The most straightforward route to fix this is to clean it regularly or replace the filters with a new one.
