Frequently Asked Questions About Furnace Repair in St. Charles

Which Issues Require Furnace Repair in St. Charles?

You may be wondering what caused the issue that required furnace repair in the first place. There are a number of common furnace problems that can be resolved with professional furnace repair in St. Charles, including:

  • Faulty Thermostat: Your thermostat controls temperatures for the whole house, so if it is not working correctly for some reason, it sends the wrong signals to your HVAC system. On the positive side, you may just need a replacement thermostat, and they are not expensive to replace.
  • Dirty Air Filter: If your heat won't turn off or on, or you have excessive amounts of dust and allergens in your home even though you clean regularly, a clogged filter is likely the culprit. Sometimes, it's just a matter of changing out the filter, but it's possible that the filter is mangled and jammed in the mechanical parts of your furnace.
  • Pilot Light Is Out: It's possible your pilot light was blown out accidentally by a random air draft and can easily be re-lit, but if it goes out often for no obvious reason, there is a serious issue that needs St. Charles furnace repair services.
  • Blower Fan Is Always On: If you have noticed that your furnace's blower fan doesn't turn off at all, it is likely being caused by a bad limit switch. However, it could also be a problem with your blower motor housing or blower motor lubrication ports.
  • Yellow Burner Flame: Your furnace burner should have a mostly blue flame. If it looks yellow, that is a sign that your burner is dirty and/or is not getting adequate oxygen to combust fuel and needs to be professionally cleaned.
  • Malfunctioning Thermocouple: Your gas furnace has a part called a thermocouple that turns the gas valve off when the pilot light goes out to avoid gas seeping into your home. But if your thermocouple is not functioning correctly, it may have trouble detecting the pilot light and turning the gas off even though the pilot light is working normally.

Is It Dangerous to Have a Natural Gas Furnace?

Natural gas furnaces are safe, effective heating units that are often preferable to electric models for a variety of reasons. However, a deteriorated unit that hasn't been well-maintained can pose a risk of a gas leak or carbon monoxide leak. It could be due to a cracked heat exchanger or a worn out seal. Natural gas is colorless, tasteless and odorless, but manufacturers add a sulfurous, rotten egg smell so it's easier to detect. If you notice an unusual smell lingering near your furnace, you should open windows, leave the house and call your local HVAC professional. It's also a really good idea to have carbon monoxide detectors in place. They need to be located close to the floor on every level of your home, particularly near sleeping areas. This is why preventative maintenance is especially critical for gas furnaces. With routine maintenance and the occasional repair, there's no need to worry about danger from your natural gas furnace.
