Excel installed 2 heat pumps. Teddy Downy was my sales rep. He was so professional, knowledgeable, and responsive. I'm a single mom, so he worked with me on different options and prices, which was very much appreciated. He was also very patient with my slow decision making. The technicians that installed the units were incredibly helpful and respectful. I work from home so they would always make me aware of any loud noise that was going to happen and cleaned up any mess they made. I would highly recommend this company! I am thinking of also getting a 3rd one in my basement next year and will definitely call Excel to install!

I cannot say enough about Keith and his crew! I've used them at my home for a new hot water heater installation, plumbing, and maintenance on Rinnai heaters. They have also done extensive plumbing & A/C work work at the restaurant. They are very responsive and knowledgeable. Highly recommended!!

Keith Trafton and his team are a top notch group. We've called him on 2 occasions when we needed help, and help as soon as possible: one for a malfunctioning propane heater and the most recent one for a leaking water heater. On both occasions we received call backs within 2 hours and then Keith or one of his employees arrived by the end of the day. They were professional, polite and clearly explained what needed to be done. The water heater disaster occurred during a snow storm but Keith was at our home by mid-morning to assess the situation. Our necessary new water heater and 2 of Keith's employees were at the house in the afternoon and everything cleaned up and assembled by 4:00 p.m. The receptionist and scheduler we extremely professional and called to let us know when the guys would be on their way even after the appointment was made. Great company!

Excel installed a new instant hot water system for us. They were easy to work with from th sale, Installation, and followup perspectives. There were no unforseen expenses. I would recommend them for any heating or cooling need.

Not a long wait for service. Confirmed the week before and also when the tech was on his way. They coordinated with the new propane provider. Easy to access office support that always got right back to me. The technical explained operating the new equipment to me. He did a beautiful job. And the price was $6000 under my other estimates. I couldn't be happier.

Keith at Excel is an experienced and friendly contractor who helped us with our major home remodel last year including removing an old oil furnace, tank and chimney, and installing a new efficient hybrid gas/ heat pump heating system with new duct work. He also worked with us to design and update our plumbing and electric for our kitchen and bath remodels. All the work was professional and top notch. If there was ever an issue with the work or equipment, he was quick to back his work and fix at no charge. Everything was done within projected budget. He has a wealth of knowledge and resourses in building trades. Highly recommend him for HVAC, plumbing, electric, roofing, or helping coordinate your remodel!
