I just want to say thank you to North Star. You guys have been so reliable every time I've called for aervice You were able to get somebody out here right away. Customer Service has been very helpful during a stressful time. Your technicians have been very insightful. When it is so hot and your AC goes down you get a little cranky. So thank you for putting up with me. Most people write to complain. But when a company does good you just want to give them a big KUDOS!

My 22-year-old air conditioner gave out in the midst of the heat wave and I called for help. Rick came out and examined my system and as I had suspected let me know I needed a new unit (couldn't add R22 anymore and it was out). New units are expensive but they offer financing and after some googling I went with the lowest standard model and was able to have an install the next day, so just one day of sweltering!

Juan and Alan came out and did a professional job installing and when they ran into a problem with my existing blower (located in the base heater) Frank came out and was more than accommodating and even drove for an hour to get a replacement. Very satisfied with this company and my overall experience. Everyone was courteous and pleasant despite the heat and I'm back to enjoying a cool house.

I have been using this company since COVID back in 2020. Hot water heater went out and after calling several places that do that kind of work this company was the only one to call back and come out despite the fear that pretty much stopped everything. anyway no judgement, since then they helped with many upgrades. they are a new heater and AC, some bathroom upgrades and other improvements. today Jesus came out and replaced some old angle stops and the powder room faucet. he was quick and everything was fine . I suggest you give them a try and if you do anything major get one of their maintenance plans . that ensures you keep your HVAC in good condition and it saves you money.

Had a technician come out last Wednesday to check my heater, he was courteous, wore a face mask, checked my heater, said it was shot, I needed a new system 55 hundered. Today I had a second opinion, he said my furnace isn't that old, fixed it to the tune of $65.00 , thank God for second opinion!

I have used John Martin Heating and Air for decades. He is an honorable man, his employees are honorable and hard working. But, he retired and North Star took over his customer list.

The North Star employee Juan came out to my home and told me that my floor heater was basically not up to code, he quickly threw out some verbiage that sounded like official state mandated code supporting his deduction.

To to the mandated retrofit to bring my system to code would cost me over $1,800! I asked when said law went into effect and he said for a very long time, years. I asked him why John Martin never told me this and why would he leave me in danger of not bringing my unit up to code - red flag(!!!) John Martin would NEVER do anything other than by the book.

Juan got a bit huffy with me, I asked him to please calm down and again asked how the work he said was necessary when John Martin has serviced my equipment for many, many years and never had issue. I think Juan realized he was caught in a shakedown which ended our communication.

I then called North Star and spoke with the receptionist. I asked for the owner whom she said in Tommy - she would not give me a last name. She said she would pass on my concern to the office manager. I had asked for the owner. She was hesitant to give him my concern.

What kind of a company doesn't tell a customer the owners last name? Something tells me don't walk, run. Just saying if North Star tells you that you need expensive retrofitting equipment on your unit, get a second opinion - this company screams shady!!!!

I got a call from the owner, Tommy within the half hour. I will give him that. He agreed to go access the situation and get back to me. Update to follow....

John A. Martin Heating & Air, Inc. was highly recommend to me. I called them for an appointment for a service call to see what was wrong with my air conditioning. They came the next day. Their technician Bruce was the one who came out. He was very professional and prompt. I will use them for any future air or heating problems I have. I highly recommend them.
