In our situation, this company was neither competent nor honorable in correcting their mistakes…read more Disregarding the Bosch installation manual, they installed a heat pump system in an inside corner, directly underneath our bedroom windows and less than two feet from our neighbor's bedroom wall. The noise was so objectionable that we couldn't sleep in our bedroom and our neighbor said that it was so loud that they would need to move if it wasn't corrected. Still, it took two years and an appeal to Bosch to get AMS to move the unit, which they did in January to a location of their choosing. Unfortunately, their technicians did not properly prepare the ground under the new location. In April, the rhubarb that had been in that location grew so strongly that it tipped the unit enough that it was in danger of falling over. We secured the unit with a tether and reported the problem. AMS sent the technician, who had installed the unit in that location, to investigate. He admitted that he had noticed something under the new location, but proceeded without removing it, thinking that it wouldn't be an issue. AMS then charged us for the technician's visit and has refused to correct the situation unless we pay for the procedure. The problem remains unresolved and AMS has not responded to our objections. The unit remains tilted. Had I seen the many negative reviews on this company, we would never have contracted with them for this $30,000+ project. Hopefully this review will help others to avoid our mistake.

Needless to say, I'll address some possible concerns. I've used AMS for 2 complete HVAC systems after moving a few times. Yes, they are not the most inexpensive but they install the best product you can buy, and do it very well with expert tradesmen (ie their staff). My advice, don't go to a high quality business expecting discount prices. I'm pretty sure they understand they deliver a great product and are not willing to sacrifice their product / reputation to make the few unreasonable customers (briefly) satisfied (ie until their next complaint). I have found their customer service to not only be extremely responsive, but attentive, honest, and loyal. After our final move, we (voluntarily) pay the annual fee to have additional on demand service from experts, during off hours. That is absolutely fair.

Overall an excellent experience, I have a new plumber. Will absolutely use him in the future and fully recommend him to anyone needing plumbing work.

After dealing with several private-equity backed HVAC companies that felt more like high-pressure…read morecar dealerships, we were relieved when Gill from Warrior Heating and Cooling came by. From the start, he was honest, thorough, and transparent. He took the time to explain everything clearly and never once tried to upsell us on things we didn't need. We decided to replace both our AC system and gas furnace (after the furnace died on the morning of the first blizzard!) with new American Standard units, and Gill gave us a very fair and reasonable price. While Warrior may not have had "7 trucks ready to finish the job in one day" like some of the larger companies promised, Gill and his team focused on doing the work the right way -- with care, professionalism, and attention to detail. What really stood out was the customer service. Gill even helped us install and set up a new smart thermostat I had purchased myself. It's rare these days to find contractors who are both skilled and genuinely trustworthy. We'll absolutely be calling Gill again for any future HVAC needs, and we highly recommend Warrior Heating and Cooling!

He even called on Thanksgiving Day to ensure everything was satisfactory. A few years ago, I told him the 20-year-old AC unit finally needed to be replaced ... he repaired it for about $200; he could have easily sold me a new unit. This year, I choose to replace both AC units (24+ and 15+ years old) before they ceased to function when summer arrived, and called M&M. The base needed to be rebuilt, and they arranged for that, as well as installation of the new units. They always respond quickly and the work is impeccable, and I feel I can trust their honesty.

At the first visit we were told by an employee that we would have to replace our garbage disposal, which turned out not to be correct. At our second call, the issue was not resolved (by Chris himself), and he had to send an employee out again the next day. Would not have been a big deal but on our third try with Belli, they refused to go out and get the needed part. That's standard for a plumber. But suddenly they had a new policy that they would not make any purchases because supposedly another client was unhappy with a prior purchase. They refused to listen when I told them I didn't care what they purchased, and Chris never bothered to respond to my email. Needless to say, we immediately hired another plumber who came right out (after purchasing the part) and did a great job, and this was our last attempt to work with Belli.
