Like other 5 stars reviews, I felt the same way on Boris' service. He is very honest, hard working, and he will try to save you as much as he can.
I had his service 2017 summer. Yup ! this is a long past-due review.
In June 2017, our AC was not working properly. The fan is running but there's no cold air, just hot/warm air came out. I first called this "400+" 5 stars reviews company. The guy seems very knowledge and charged $225 for his 1hr of inspection work and explaining to me and my wife. He sent me a very detailed report and said I have a leak on the coolant line. He quoted $1400 to patch/seal/glue(whatever I forgot) the line but he DOES NOT guarantee it'll last more than 1 year.
Then I found Boris, he came with a quick inspection, less than 30 minutes (no charge). and told my wife we just need to refill the coolant. We said the other company found a leak. Boris said, nope, there's no leak, you can either believe me or the other company.
So...........we chose Boris because it's CHEAPER, lol. It was ~$400 to refill the coolant.
Two weeks after Boris refill the coolant, our AC stop working again. We think "Oh, no! there is really a leak, so in just two weeks AC stops working again" We called Boris and he squeezed some time out from his busy schedule (yup, it was really hot that June) He found out it was the fuse. He quickly changed it and our AC has no problem after that. And he didn't charge us on that big fuse !
Anyway, I hold my review for two years because time will tell!
Boris, we are really thankful to have you to fix our AC with the most honest and affordable option.
You don't have to message and ask me what's the name of the other one, there's only 1 with 400+ reviews and still have 5 stars. They may be good and professional, but it'll cost you ! I'll stay with Boris.

I can't say enough good things about Boris. My heater suddenly stopped working. Panic! Boris came when he said he would, called 15 mins beforehand too to confirm. He quickly figured out the problem -- old batteries. Silly me!! So rather than charge me the full $80, he only charged $20, and he provided me with new batteries. Then on his way out, he thought to check my filter. It was gross!! He replaced it for me and wouldn't take more money.
I love supporting small businesses wherever possible. Call Boris!!!

Boris is a miracle worker and an incredibly fair man. We've used him four times over the past three years (twice for our home and twice for my elderly mother-in-law's home) and have been incredibly impressed by his service. The first time we called him was three years ago for a second opinion on my mother-in-law's furnace, which had stopped working. The first company we called said the unit was unfixable and needed to be replaced (~$4000). We called GB for a second opinion. After an assessment, Boris determined the circuit panel needed to be replaced (~$500). An hour later it was working just fine. The second time was for our AC. We thought we also might have a blown circuit panel. Instead, Boris discovered that we had clogged air filters (our fault!) which was tripping a fuse. Easy & inexpensive fix! We had to call again this week for my MIL's unit and feared this time it might be time to replace. Once again, he was able to replace an old dusty part and clean up the inside and it's working again and she's warm and toasty!
He responds very quickly, is clearly trying to solve issues in the most cost-effective way possible, and he's also a super nice guy! HIGHLY recommend GB/Boris for heating and AC issues.

I was referred to Boris by a part manufacturer who doesn't sell directly to the public. Boris is on their list as one of their service providers. From the moment I explained that I needed him to order a part and install it he did not want to help me. He told me he doesn't want to work on my equipment and kept repeating that he doesn't order equipment, he installs it. I explained that I did want him to install it, but that he would need to order it as it is a custom part and he is listed by manufacturer as a dealer/installer of this particular ac equipment.
After a couple minutes Boris simply hung up on me. I couldn't believe he could be so rude when I was being so polite. He really struck me as a guy who is not into his customers at all. It's too bad because if this part is unavailable (something he didn't even bother to find out) I'll end up needing an entire ac/heating replacement unit, which could have made him thousands of dollars. Now he just ends up with a bad review.
