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!

On simple service call to fix the heating system which turned into continuous hassles and making payments for $3k+ over a 4 week period with no heat, waiting on wrong parts ordered and begging to get it fixed. No customer care from home office and no clue what the field team is doing or charging you. After all that I had to start over with new company to actually get it fixed and then month later I was sent additional bogus invoices to add insult to injury thus my posting. Do yourself a big favor steer clear of major. No stars.

I have used Major Heating for several repairs over many years. Every tech that has been here has been punctual and professional. Well, it finally happened, I needed to actually replace my 25 year old furnace. Of course, I used Major for the replacement furnace. The installer, David, was not only punctual, but early. David and his team worked hard throughout the day to ensure I was up and running before the snow started tonight. After finishing the project, David ran through everything that he did and how to properly operate everything. Also, part of the previous piping had been improperly

Was told the tech would be by in less than 10 min as he was 'a few blocks away'. He shows up an hour + late, finds the furnace issue fault in less than 2 min (loose wire), then bills me for 1.5 hours of work, stating that they charge for travel time from the last job. He said he had to travel from another city, during rush hour, etc...Totally corrupt system when it comes to billing. The office manager failed to share this info and did not provide a discount as most services charge, once they arrive at a job. I argued the fact that what if the tech didnt show up for 3 hours, would I have

Major heating is old school, small town, down to earth good solid company! I have an 1896 Victorian that had the original steam boiler in it which they have serviced for years to help me make it last. Unfortunately and just died and they did an amazing job of installing a new efficient beautiful new boiler. I just can't say enough good things about them!
