Hot Water Heater rusted out and leaked in my basement. Aaron and the team at Superior responded within hours and not only inspected and quoted the replacement but were able to decommission and install the new water heater within the same day. The installation team was professional and explained everything. Really happy with the whole experience!

Superior HVAC Cambridge repaired my furnace when it suddenly stopped heating. They responded quickly, arrived on time, and explained the issue clearly before starting the repair. The furnace was fixed the same day and worked perfectly afterward.
