Best Heating And Air Conditioning in Boston MA

As a real estate agent it is important to be able to recommend vendors of all types that I can count on to do the job for my client. This company has not only exceeded all my expectations for my clients, but done so in a timely and professional way. Cannot recommend them highly enough!

Very fast and reliable great service

Showed up immediately after calling and completed work quickly at a great price.

They were on time and very helpful. The service was great, and would recommend McMahon Plumbing and Heating to other client's.

The team was so great - willing to schedule and come at short notice, reasonable fee for the visit, quick diagnostic, quote, and repair - everything was done in a couple hours and I am so happy with the service. Also great people who explained my options and were so friendly and professional.

Will use them again for sure

After numerous phone calls , we hooked up with Steve and his crew. We will be customers forever. They are, without a doubt, the most professional company to work with. We had no heat in various parts of the house for 9 days and they worked diligently to get it back on. They also fixed three broken pipes. Thank you True Blue Don’t take this personally but I hope to never see you again unless it’s to buy you a beer. !!!
The Mulligan family

Very grateful to Maury, who arrived on time, checked out our compressor in the pouring rain, looked at all options regarding our air handler, and generally answered all of my questions including even giving me an on-site quote. He’s extremely knowledgeable and professional, I would highly recommend!

Great job. Very satisfied

I called Alpha Omega to replace my Navient Combi Boiler. Sam responded right away and was able to arrive the same day! He was so helpful and very fast in the way he worked. His price was way better than the other two companies I tried before so I saved alot of money and frustration. Definitely will use this company again. Thank you!

Akian Plumbing was friendly, efficient, and affordable. I appreciated that they were very straightforward with their pricing and also offered excellent customer service. They replaced my water heater and did an excellent job (they also charged hundreds of dollars less than all the other companies I quoted ahead of time). I absolutely plan to hire them again in the future!Recent update: I called Akian to repair a few issues with my sink and faucet, and once again, they floored me with their excellent customer service and transparent pricing. Randy, the technician who worked with us, observed COVID protocols and made the whole experience feel safe and easy. I stick by my original review and will continue to call on Akian in the future!

Sila should be called SILA THE RIPOFF COMPANY. My Lennox furnace (from 2014) failed during the record cold snap on 2/5/2023. I called Sila and said it was a Lennox, and what parts were working (fan, electronic ignition) and what weren't (no flame, no heat). Sila's phone rep explained that for weekend service just having a technician come to the house would cost $375, plus $90 per half-hour after that to fix anything. Steep, yes, but they told me they had a fully stocked truck so the parts would be available. It was very cold out! so I let them come. After about 10 minutes in the basement, the service tech informed me that the gas valve on my furnace was dead and needed to be replaced. So you have it on the truck, right? No, Lennox parts have to be special ordered. We can't contact their warehouse until Monday morning. Then he asked for payment of $375. I pointed out that the truck was supposed to be fully stocked and that I had told the person on the phone that I had a Lennox furnace. If Lennox parts are not carried on the truck I could have waited until Monday morning for a regular service call at $125 instead of the weekend price of $375. Nope! He insisted on full payment based on listening to a tape of the call. But that's not all, folks! He quoted me $1,150 for parts and labor ON TOP OF THE WEEKEND CHARGE of $375. He told me that price before he left. Then he called me again on Sunday to verify $1,150 and ask me if I'd like to schedule it? And then Sila sent me 2 follow up emails trying to schedule the work. No plumber has EVER tried so hard to rip me off. Once was enough. No thanks. My regular plumber charges $100 for a housecall and does not deceive his customers. He had me send him a cellphone pic of my furnace, and of the model and SN of the gas valve. He verified with Lennox that it was under warranty (10 year warranty, we're 9 years in.... so the part was free). SILA THE RIPOFF COMPANY didn't bother to ask about warranty coverage, so were they planning to charge me for the part that was free? Once the part arrived, my plumber was able to put it in, in under 30 minutes. He charged me $100 for the housecall and $80 for his time which ALSO included fixing a leaky sink in the same visit. So, let's recap. My plumber charged a grand total of $180, for a visit which included not only fixing my furnace with a FREE part because he bothered to check the warranty coverage, but also included fixing a leaky sink. SILA THE RIPOFF company charged me $375 for a weekend housecall when they KNEW I had a Lennox furnace, they KNEW they didn't carry Lennox parts on their truck, and they KNEW they were going to try to get me to pay them for ANOTHER housecall plus parts and labor... and their PLAN was to charge me $1,150 on top of the first call. For a grand total of (they hoped) $1,525 for 2 visits which would have totaled under 45 minutes total time spent in the house. Versus $180 total from my honest regular-guy plumber who also fixed something else during his visit. DON'T USE SILA. DON'T LET YOUR FRIENDS USE SILA. YOU HAVE BEEN WARNED.

The plumber is really nice and helpful. I got several issues which my builder is not responsible for. He comes and fixes quickly. Great job! Thanks so much!

You guys are Boston's foremost experts with HVAC and refrigeration systems. Thanks again for your help.

Excellent service. I had a plumbing emergency over the Easter holiday. Nobody else would come out to help me. These guys guys did, even though I lived well beyond their usual service area. They took care of the problem with professionalism and left everything clean, tidy and (most importantly) functional. In the end, the cost was very reasonable. Highly recommended.

I’ve used Michael on at least 10 projects. I’m a contractor and I have never had a problem with his service or price. The reality is that people’s time is worth something, especially on a weekend emergency call.

They show up on time, do a decent job, for the price they state.

While not inexpensive, they are fairly priced and stand by their work. We've had them do simple pipe repairs, hot water heater replacement, and fairly complex gas pipe relocation that involved fussy work due to a joist being in the wrong place.

All work done well with no return visits required.
