Recent Review: A routine inspection revealed a leaking heat exchanger in the furnace and carbon monoxide leaking into the house. AirMasters helped me determine how quickly I needed to get this repaired, then worked through about eight options to find the right solution for me. I have a 500 gal propane tank already in the ground and a prepaid fuel contract, so they selected a "dual fuel" heat pump that allows me to keep using propane at my discretion as a backup to the heat pump. It also provides huge savings in fuel costs - the new system is at least 25% more efficient than what it replaced, plus uses cheaper fuel. AirMasters moved my installation date three times to fit our holiday schedule changes and finally installed the day after Thanksgiving. Family was still here during the installation, but they worked around us all. They started and ended on time, put down floor coverings, kept doors shut as they came and went and wore boot covers in the house. They removed all the old equipment and thoroughly tested the system before they left. The following week they sent a different serviceman to inspect the work and check that the system was operating normally. I have never had a complete heating and air system replaced, but I could not imagine a smoother operation. I was completely satisfied and thoroughly impressed with the quality of the operation.
