How to Fix Most Common Heating Problems - dual heating system problems

Finding out that your heater or furnace isn’t working can be a shock, especially in winter.
Although every heater and furnace ultimately has to be replaced, specific heating issues may be resolved without buying a brand-new system. We’ll discuss typical heater issues and the best repair or replacement options.

How to Fix Your Furnace Blowing Cold Air

The first step you should do if you’re puzzled as to why your furnace is blowing chilly air is to check your thermostat to ensure it’s set to the appropriate setting. Consider turning it up a bit to see if the change is discernible. Ensure that it is set to “auto” rather than “fan on”; otherwise, your fan won’t blow any heat.

  • If you have inspected your thermostat and are confident that it is set correctly, your problem might be any number of things, including:
  • Air filters that need to be washed or replaced get unclean over time and should be done to prevent your furnace from working correctly and blowing chilly air. Check to see if the issue is resolved by changing your air filter.

Leaky ductwork is a nearly undetectable issue, but it might cost you money if it isn’t fixed. To check for leaks, enter your attic or crawl space if you feel safe doing so. Walk beside your ductwork and feel for any blowing air. Bring an incense stick with you, light it, and hold it next to your ducts. If the smoke begins to move, you know you have a leakage. Block off any leaks and appropriately insulate your ducts.

How to Fix a Furnace that Won’t Stay Lit

Your furnace might not have a pilot light if it is recent. Instead, it probably makes use of electrical ignition. The gas won’t flow without the furnace on, thanks to the flame mechanism in these more recent systems.

When examining your furnace, keep an eye out for this problem since these sensors occasionally become filthy and need to be replaced. You may quickly repair this problem yourself by cleaning and repairing the sensors.

How to Fix a Furnace that Won’t Turn Off

Ensure your thermostat is set to “auto” rather than “on” so that the furnace will turn off when it reaches the desired temperature if it won’t stop heating and blowing hot air.
If your furnace still doesn’t turn off, one of two things might be wrong:

  • You have a faulty or malfunctioning thermostat.
  • Your furnace’s blower is broken.

To start, check the wiring on your thermostat to ensure it’s all plugged in correctly. Then, try operating your system again after putting your thermostat back in factory settings. Your thermostat may need to be changed if this doesn’t address the problem.

If you change your thermostat, but your furnace still runs, a blower problem could be at blame. For a more thorough examination, speak with your reliable heating specialist immediately. Morris Jenkins furnace repair service is an excellent place to start looking for a specialist.
