Treavor my technician was very professional and saved me money by replacing the primer motor instead of selling me a new furnace. This way I'll get a couple more years out of my furnace and when the time comes they will get my business for a new furnace. Thank you Major Heating & Air!

Lady said she would have her scheduling people call me back about getting an estimate done. Nobody ever bothered to call back.

Report
Very poor customer service and left me high and dry. Heat in my residence wouldn't work so paid Major $90 for a tech visit. Diagnosis was that I needed a new custom retrofit thermostat at around $1100, so I wanted to submit the repair as a claim to my home systems warranty. Major's office staff initially said they'd gladly prepare a detailed estimate and wrote a brief letter I could submit to my warranty provider. However, after numerous phone calls and several empty promises by office staff over three weeks, they failed to perform.
As a result, my warranty claim was cancelled and will likely be denied as a pre-exiating co edition if I try to resubmit it later on. Thernostat still not fixed. Numerous other reviews share similar stories of Major leaving them hanging; do yourself a favor and look elsewhere.

They were able to get to our house within an hour of calling after trying many other heating companies who didn't answer, did poor work at our house previously, didn't call back, etc. I highly recommend them and will definitely use them again in the future! Service: Heating system repair

Major Heating and Air sent a representative out to look at our situation and write up a quote in October 2020. Even though we followed up with him on several occasions, two months later we never received a quote. At this point, we will find something who wants to do the job to help us.

Donie came over yesterday and assessed my boiler. Said a part a different firm said needed to be replaced just needed a bit of corrosion to be buffed out as it was cosmetic only. He also handled a couple other minor issues. Great guy! Very knowledgable and friendly. I appreciated not having to replace the part! Great people all around. Thank you!
