I had my heat pumps installed by MAC IN September 2020. Since then, I have used my back-up Rinnai only four days total a couple years ago when we had a few days in February that reached lows in the -40s. It’s handled everything else Mother Nature has thrown at it since. I especially enjoy the “dry” setting in summer which takes all the humidity out of the house without needing the extra AC. However, I am cozy warm in winter and blissfully cool in summer, always! I am very pleased with the personalized and expert staff and servicemen at MAC. So friendly and knowledgeable! Go with MAC they have your back!

Reviews
Very professional
The technician who serviced our heat pump was very courteous and seemed to be very efficient in doing the work and getting it done. He said that our unit was very clean and that it probably didn't need to be serviced for 2 years which is good news.
My only issue with the service is the price. think that a $180 is rather excessive for what these technicians do and the amount of time they spend doing it. I will be attempting to learn to service the unit myself or find a less expensive alternative.
