      Signs You Need a Furnace Repair

      • Reduced Airflow

      Poor airflow coming from your vents hint that there could be a problem with the ductwork or blower motor. We use advanced techniques to eliminate issues and prevent them from recurring. That means that we’ll take the time to perform thorough diagnostics and ensure we have considered every part of the problem so we can get rid of it for good.

      • High Energy Bills

      It’s a big red flag if energy bills spike without a corresponding change in usage. This means there’s probably something wrong with your furnace that we need to address, quickly. When it comes to furnaces, our focus is on energy-efficiency, and we don’t stop until every unit operates properly. 

      • Inconsistent Heating

      If your furnace produces inconsistent heat, there’s probably an issue within the system. That’s why we perform in-depth evaluations to determine the root cause so we can catch the problem before it escalates further.

      • Strange Noises

      Your furnace should never make strange noises like rattling or banging. If this happens, there’s probably a system failure in your furnace. We move quickly when someone needs an HVAC repair so that we can restore your system quickly and minimize household disruption. 

      • Frequent Cycling

      It’s not normal for furnaces to turn themselves on and off again. So, if you’re experiencing this issue, it’s time to call us for help. With their decades of combined experience, our technicians can handle any furnace repair and will provide you with the honest recommendations you need to make the best decision for your property.

      Guaranteed Plumbing always does great work. Everyone I spoke with was friendly and extremely knowledgeable. I used them years ago to have all plumbing put in a brand new bathroom, and called them immediately when a frozen pipe burst. Highly recommended...
