      Signs You Need a Boiler Replacement

      • Age of the Boiler

      Boilers typically last 10 to 15 years. If your boiler is approaching that age, it becomes more prone to breakdowns and less energy efficient. 

      • Frequent Repairs

      If you’re always calling us for a boiler repair, it might be time to consider a boiler replacement. In fact, an HVAC replacement can often save you money in the long run.

      • Inconsistent Heating

      If some parts of your home are hot and others are cold, there may be a problem with your boiler as it is likely struggling to maintain the desired temperature. 

      • Rising Energy Bills

      Spikes in energy bills without a change in usage mean your boiler is likely consuming more energy than necessary to heat your home.

      I’ve had Guaranteed Plumbing out twice in the past two months to replace a garbage disposal and fix a sink that was not working. Super responsive, quick to come out, they leave the area clean, and prices aren’t bad
