    Brad from Brennan was great. He went through our old furnace and said it is in good shape. He explained what possibly caused it to stop and restart in a few hours and that there is 'No Need to Replace' it. Best service on the planet!

    I needed a furnace check-up/ tune up. The technician Daniel showed up on time with an awesome attitude. Very considerate about our surroundings. And went right to work. He found some things that needed attention explained to me what they were showed me a part that needed replaced gave me the cost of the part and asked me if I wanted it replaced. Daniel did all the work cleaned up and was done in no time.. He let me know my furnace was in good shape. Very professional . I would use Brennan again and again.
