Signs That You Need Heating Repair

If you’ve never experienced a heating system malfunction before, you may not know when to call for service. Look for these five signs that you need heating repairs as soon as possible:

  • Sudden loud noises: Most furnaces, boilers and heat pumps make relatively quiet noises when they turn on or switch off. If your heating system suddenly begins making clanking, banging, or other loud noises, there’s a good chance you need repairs urgently.
  • Increasing utility bills: You already expect to pay more for heating during the winter months. However, if your utility bills keep rising and don’t seem to decrease when the cold temperatures pass, you might have a heating problem on your hands. Call our team to get to the bottom of the problem.
  • Inadequate or uneven heating: Your furnace, boiler or heat pump should provide adequate heating power to each room that’s connected to your HVAC system. If some rooms never seem quite warm enough, or if your heating system has begun to pump more heat to some rooms than others, your system may need attention.
  • Poor indoor air quality: Your heating system should help keep your indoor air clean and your home’s relative humidity level moderate. If you find that your furnace, boiler or heat pump is contributing to poor indoor air quality, call our team of experienced repair technicians. We’ll determine if your heating system is at fault or if you need indoor air quality add-ons.
  • Yellow pilot light: If you rely on a gas-powered furnace to keep your home warm, there’s an easy way to tell whether something is awry with your heating system. If your furnace is working properly, the pilot light should be blue. If the pilot light appears yellow or orange, your heating system could be polluting your home with dangerous gases.

If you have experienced these issues, you should consider getting a heating maintenance plan if you don’t have one already. Maintenance plans extend the performance of your heating system and help to prevent costly heating repairs. Consider purchasing a maintenance plan with Den-Son today.
