Report
My heating and air conditioning unit's life was extended thanks to annual service by M.J.Mac. But when the time came and the cost to fix and keep it running efficiently wasn't cost effective, they worked with me to find the right system to replace my 20+ year old system. I cannot even begin to thank them enough for the service calls this summer when it was outrageously hot and my ac finally kicked the bucket.
They worked hard to diagnose and provide repair estimates. Ultimately we chose to replace the entire unit, and we are amazed by their hard work to make everything perfect. The new system runs extremely efficient and we couldn't have been happier. Until today. Today, I received a rebate check. Not only was the service outstanding, but they even worked after the job to get me money back. Very impressed. Jay and Matt worked extremely hard to make sure evening was working and we were completely satisfied. and now I'm even happier. Not only was their pricing on point but their service is unmatched. Definitely a customer for life. Special thanks to Jay for finding a unit so fast during a time when they were in short supply!

If you have any HVAC or Refrigeration needs I would highly recommend calling MJ MAC INC. Had an issue with my system at my home. This company dispatched a tech same day and charged my system and the price was very reasonable. My uncle also owns a bar and needed service on his walk in box. MJ MAC INC. called back right away and sent some one out immediately to fix the issue. Eventually he needed a new walk in box and again called MJ MAC. The service was incredible once again. They are wonderful and I highly recommend!

The service technician from M J Mac came exactly when they said he would. He was very helpful and knowledgeable in regards to my oil heater. Our service tech also was very clean and worked quickly to do our repair. I would highly recommend using M.J. Mac for any type of HVAC work, they are true professionals.

Awesome Company! My heater went bad on me and I called 3 companies. Mjmac beat both prices by a good amount. As well as the work being done by a professional technician! I was also very happy with the work when it was finished! " The same day I called, my heat was working that evening" I would recommend this company to my friends & family or anyone looking for a great installation and fast service. Got the job done in a timely manner, also thank u for the 2 technicians for being so polite to me and my family!

MJ Mac is one of a kind! I needed service for my AC immediately when temps were soaring and Jay and his team was there within an hour. I have referred him to many people and everyone says the same! Quality Service at a price that is unbeatable! I would highly recommend MJ Mac to ANYONE who is planning work or needs help in a pinch!
