Well, they did it again. In the winter it was my heater, now the AC. Just my luck. I called MJ Mac and they were out there the same day and diagnosed the problem. The part arrived and was installed less than 48 hours later, and they even let me know the part was still under warranty! Thanks to them, I'm enjoying the cool air once again.

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!

M. J. Mac Inc. replaced our entire A/C system, and did it quickly! In a matter of 3 or 4 days, the team replaced the outside condenser unit, the lines and duct work running through the house, and the air handler in the attic. They were always professional, courteous and cleaned up up after themselves at the end of each day. They even let our little 3 year old pretend he was helping out! Highly recommend these guys!

After 3 quotes with other companies, we decided to have M.J. Mac, Inc.replace the furnace motor, the same day of the evaluation. The technician was knowledgeable of the system, patient answering questions, considerate of our home, (by placing shoe covers over shoes), and before leaving, he thoroughly checked the system to make sure there were no issues. I highly recommend this company to homeowners who are looking for excellent workmanship! yvon

On one of the hottest days, our air conditioner decided it did not want to blow cool air. I called M.J. Mac to schedule an appointment for a tech to come out. I thought it would be at least a day or so for someone to come out, but to my surprise, not only did they schedule a same day visit, two techs were at my house with in an hour after hanging up the phone.

The techs explained what the problem was & fixed the problem that same day. They were fast, efficient & cleaned up after themselves. First time calling & using M.J Mac services & from the experience I shared with them, they will always have me as a client. Special thank you to techs NB & NZ for making my family cool.

Been using M.J. Mac for residential AC startup service and maintenance for the last few years, after calling them for emergency service on our heater. All of the techs that have come out to our house (including the owner) arrived on time and were personable, extremely professional and thorough. You can tell the company really cares about the work they do and we found their service rates to be perfectly reasonable. Quality service, great guys, great company - highly recommended!

We have used MJ MAC 3 times now, twice for AC issues and once for a hot water heater. They are a very good company to use for service. Fast call back and when our hot water heater went, they showed up at 3pm and we had hot water by 6:30pm. The owner is super nice guy and talks very passionately about the work he does. His employees are nice and very knowledgable as well. I always feel in good hands with them and I trust that my best interests are being taken care of. I would not hesitate to recommend to anyone

These guys are true to their work and their word. The service tech arrived right on time as promised, came straight in and got to work! Within minutes he was able to find the problem and fixed it. The price was reasonable, and the end result was excellent. I won't let anyone else touch my heater or my A/C!
