“Excellent professional. Determined the issue and arrange for the part in an expedited manner and came back the next day ! Most importantly was able to "temporarily" enable the furnace to heat until the damaged part was installed next day.”

“Shawn, Tim and Kyle were amazing. They are all very smart and highly knowledgeable. Each one explained their area of expertise and gave expert recommendations. I'm very grateful for such a caring and conscientious group of servicemen. I highly recommend all 3. Benjamin Franklin is a good company to do business with.”

“Matt Beebe came over early. He tested all the lines coming from our HVAC system and hot water system. He was able to diagnose the issue right away as being a frozen exterior pipe that was causing water to back up into the hot water heater pan.”

“My whole journey from start to finish was very eye opening. My heating unit and duct work were pretty old. With my first phone call, Malisa stepped up and helped me with my anxiety and financial issues. She and the crew, Austin, Justin, Jeff, Shawn, Matt and anyone else I may not have seen who were under my house were professional and sensitive while guiding this old lady thru the whole process. I thank God for sending me to my "guardian angel", Malisa. I would definitely recommend One Hour Heating and Benjamin Franklin Plumbing. God Bless. Nancy C.”
