A rather complicated and sad review. I am a senior citizen. My gas heating system needed…read morereplacement after a fire in my furnace. $20,000 and I replaced it. The very next day the second heating system I had in an addition failed. I was distraught!! Net Zero gave me a great quote..several thousands less than other HVAC. What they did not tell me that they were only electric heating contractors. So after paying $12,000.00 for installation I now pay an electric bill of $1000.00 a month in the winter. They walked by a brand new gas system in my home..disengaged a second gas heating 50 feet away and installed a unit that is costing me a thousand dollars a month. Not one of the employees ...installers. or project estimators...addressed what a poor and unkind decision this was. Now I have to redo my heating system...sell my house...unable to retire . Would they do the same to their mothers..grandmothers? This is a sad and sorry company. Yes I know I'm a stupid elderly woman with no recourse from people like this. I just hope this warns others to avoid this snake company.

This review is merely a confirmation that Net Zero continues to offer outstanding service.

He gave his honest opinions of what could be replaced and what the rough costs were for each component plus labor. He also explained what he thought was the best option to keep our current system running at it's best, which I chose to do. He re-gassed our unit and added a startup capacitor which seems to have done the trick! The outdoor unit kicks on easily, runs quiet and consistently now. And of course the AC blows ice cold now. He even gave recommendations for future maintenance for not only the AC unit but the boiler as well. I can't recommend Total Comfort Mechanical, and James, enough!

We arranged for Jay to come by the following day, not only was he there on time but he resolved the issue quickly and for a fair price.

I cannot recommend Conway enough.

My old steam boiler developed a…read morecracked heat exchanger, and Max Heating was prompt, informative, and willing to do the replacement during the New Year holiday. Dan and Sam have been stand-out with the depth of their answers to my questions. I appreciate that immensely as a demonstration of how much they care about the subject matter, and how much they care about ensuring I'm properly informed on what is happening. Sam and his crew were out all day yesterday dismantling the old boiler and installing the new one. They were friendly and engaged the whole time letting me observe the process. Sam called me over throughout to show me up close what had corroded in my old boiler, and to explain to me how it happened. He did the same during install of the new boiler to demonstrate all the critical aspects for maintenance--including letting me unscrew and rescrew a piece to practice for future cleaning. The new boiler is running smoothly right now. I feel like I understand its pieces. Sam even took an interest in diagnosing why my bathroom heating panel (which has never worked) wasn't heating. He cleaned out its vent and it has heat now. My cat is very happy to be warm right now. From the way Sam and his crew talked through all the aspects of the work they were doing, it was clear they take pride in the quality of the work. This wasn't just a job to get over and done with. And what's more, they did it for $2k cheaper than my competing quote. Max Heating and Cooling will be the first people I call for any plumbing projects I have going forward.

Their price was reasonable, the techs were super competent and nice. I highly recommend them!

Their price also included a 3 year service plan. The install was scheduled 3 days after I accepted the quote, others were scheduling 2-3 weeks out. On the day of the installation, the 128 crew arrived right on time, calling ahead to let me know they were on the way. They showed up with a four man crew, 2 installers for the mini-split and 2 electricians. The work was pristine, the wiring was neat, the unit was placed on a pad and looks great! The crew (Paul, Nedim, Nick & Connor) was extremely professional and curtious. The work was completed by 3pm same day. I am 100% pleased with the work and will be using them going forward for all my HVAC needs.

Ryan was great, tried to keep my carpets/bathroom clean as much as possible and was patient in discussing my options and answering my questions. Surprisingly was able to get an appointment for install on Monday. Jared was also great. Definitely appreciate the small details and concerns to keep the carpet clean like hand carrying both the old and new water heater up 2 flights of stairs. Between the quick response/scheduling time, clean workmanship, and fine attention to detail, happy to say the leaking water heater experience felt less chaotic with 128's help! Total turnaround time, Friday 11pm to Monday 4pm hot water up and running!!

Tried at least 5 companies before anyone would even come by the house, and the first one that did offered to cut a hole in the ceiling ($600) and cut a hole in the shower tile and replace all the plumbing in the bathroom ($3500), all without even looking at the shower at all. They then tried to sell me a heater boiler, hot water heater, and all new plumbing for the rest of the house. Seemed excessive, so I called Chase. They came, took a look at the shower faucet, replaced the valve in about an hour without cutting a single hole in anything, and charged a fraction of the previous estimate. They are professionals, so their labor is not cheap, but they do excellent work and didn't try to sell me anything I didn't need.

I had a frozen pipe emergency during freezing weather with no heat in the house. They came out, charged me $300, and didn't even provide a proper diagnosis. I was told it "might be" a broken circulator -- no certainty, no testing, just speculation. Meanwhile, they created a dripping valve, and they didn't even bother to tighten it despite my requesr. They said they would send an estimate and never did -- not for two days -- while we were literally shivering in the cold. When I finally followed up, they sent a $2,100 estimate to replace the circulator and fix the valve. Thankfully, I decided to call another plumber. Within 20 minutes, the frozen pipe was fixed with much cheaper. I was told there was absolutely nothing wrong with the circulator or the valve. The dripping valve? Tightened in a few second. I paid $300 for guesswork, delay, and unnecessary upselling during an emergency situation. This felt like an attempt to take advantage of a homeowner in distress. I would strongly caution anyone considering this company to think twice.

Good technicians. Totally exploitative on the billing…read moreside. Only for the wealthy. We had to pay almost $2,000 to fix a tiny thing because, cunningly, they've figured out they can rake in much more money by charging separately for every "step." These "steps," mind you, used to be considered part of "doing the job," but are now billed separately by this company, which apparently has been taken over by a private equity firm, which explains it. For each "step," they shove an iPad in your face and demand your signature: Eg: --driving to your home (in this case, about 10 miles from Woburn): about $300 --diagnosing the problem: $600 --driving to get the necessary spare part (about 5 miles and back), which was so basic they should have had it on the truck: about $250 --cost of spare part: $200 --installing the spare part, which took about 30 minutes: $600 Interestingly, when we received the bill, it did NOT itemize these charges in terms of the dollar amount for each, instead it listed by units (eg "1:00 troubleshooting," "1:00 parts pickup"). We will never use this company again. Even though it was the company that installed the system, for which we paid 28K just a few years ago (no longer under their 2-year warranty). This maintenance visit showed that they're clearly more interested in making bank than actually building customer loyalty. Companies are entitled to make money. This is something else altogether. We never write reviews, but hope this one will serve as a warning to people needing HVAC services but unable to afford truly exploitative upcharging.
