On Saturday evening my furnace wouldn’t respond to a demand for heat so I called for a service person. Jason called back promptly and arrived at the house as soon as possible after finishing a couple of calls. He quickly determined that my thermostat was faulty and he replaced it. I want to commend your company and especially Jason for excellent and very friendly service. Having the VIP service contract is a great comfort and something I would never want to be without. P. S. Give Jason a raise or at least a hug

Kathryn Chevrier

The crew that installed my furnace was knowledgeable, experienced and efficient. What is more, they were polite, and very customer oriented. They treated us and our home with respect and care. Very simply, the best thing of all was that MACKAY heating and everyone I talked to and dealt with did what they said they were going to do and exceeded all expectations. Not all small business people do that. In fact not all big business people do that. In particular, my wide enjoyed Marty’s lecture on how to program the thermostat. Finally, the installation and the piping is almost a work of art. As you know, the other system was a piped up nightmare and caused me continuous mental pain when I just looked at it. I’m very pleased!

Adam and Mike were both informative and respectful of property, and interruptions, etc. they were both conscientious and pleasant.

Courteous, knowledgeable, the person that headed the furnace installation, thoroughly checked the system. He noticed a noise in the A/C which I have reported before and said that he would check service bulletins. The next night he phoned and said a new compressor was ordered and would call back to arrange a time to install. This is the part that customers appreciate, a person who takes the time to recognize a problem and investigate and rectify the problem. This is a dedicated employee who is a true asset to the company. I have had other service work performed by MACKAY and each one has been courteous, proficient and answered my questions. Kudos!
