      Signs You Need a Furnace Repair

      • Frequent Cycling

      It’s not normal for a furnace to repeatedly turn itself off and on again. This hints toward issues with either the thermostat or other system components. Our technicians will perform thorough diagnostics and will provide you with expert advice based on what makes the most sense for your system. 

      • Strange Noises

      If you hear strange noises like rattling or banging, there could be a system failure in your furnace. We take the time to fully understand the scope of the issue because we want you to have the best possible results. 

      • Inconsistent Heating

      Furnaces should be reliable. If yours is producing inconsistent heating, there is likely an issue somewhere in the system. 

      • High Energy Bills

      High energy bills without changes in usage mean that your furnace is probably using more energy than necessary to heat your home. 

      • Reduced Airflow

      When there’s weak or inconsistent airflow coming from the vents, you could be dealing with anything from blower motor issues to ductwork problems and more.

      Furnace Replacement

      We know that a furnace replacement is likely not your first choice, but you shouldn’t be afraid of a new furnace installation. New systems operate efficiently, which potentially lowers energy bills, and also require less repairs. At Guaranteed Plumbing & Heating, we do everything in our power to make getting a furnace replacement as simple as possible. From our affordable pricing options to our extensive warranties, we are confident you’ll be happy with the result.
