Why Does My Heater Blow Cold Air?
Common heater problems can create a lot of stress at inopportune moments. Instead of panicing, take time to do some troubleshooting so that you don’t spend money on an unnecessary service call from your HVAC contractor. In some cases, issues like your heater blowing cold air can be resolved without help.
Troubleshooting Problems with Your Heater
One of the simplest checks of your heating system begins with a review of thermostat settings. This is especially important if you have children in the house or if you are just turning your unit on for the first time this winter. An incorrect setting can lead to a burst of cold air, so be sure that you have the heating function selected. Additionally, verify that the temperature setting is greater than the current room temperature. You may also want to verify that the battery for your thermostat is good, making a replacement as needed.
Another issue that you may face, especially at the start of the heating season, is the system being slow to warm up. If the air blows cold at first but heats after a few minutes of operating, then you may not need to be concerned. This may be a matter of cold air being moved out of the ducts as hot air is forced through. If the problem continues, you may need to consult with a heating services provider. In some cases, electronic controls and timers may be malfunctioning, requiring heater repair. Additionally, dirty sensors or problems with the fuel supply can play a role.
Other troubleshooting steps to complete before you call for heater repair include:
- Check your air filter to make sure that it isn’t clogged with excessive dirt
- Verify that the pilot is lit
- Check gas valves to be sure that the supply isn’t hindered
- Verify that electrical switches are connected and on
- Check the fuse box for a tripped switch
- Make sure that your fuel supply hasn’t been interrupted by an outage with the provider
- Note any error codes on display panels
Head Off Heater Repair Needs Ahead of Time
It may be early in the season, but many companies providing heating services are beginning to see a marked increase in repair needs. It’s important to maintain your system so that you can avoid these early issues by having a thorough inspection and tune-up in the fall months. It’s not too late to have that tune-up completed now, and it could save you further problems with comfort and safety as the winter months progress. Your technician will make adjustments, cleaning burners, sensors and heat exchangers to ensure that your equipment operates as efficiently as possible. Safety mechanisms and venting components are also inspected to ensure that your furnace operates according to manufacturer standards. Home heating is considered to be the second greatest cause of fires in residential structures, making careful maintenance of your system a critical concern.
