A recent Google reviewer says the natural gas was not converted to propane and that it fried their furnace. The same reviewer says he won't respond when the family reaches out. DeMeo Heating & Cooling works out of Hyannis, and the Better Business Bureau lists it under the name Whitecap Plumbing & HVAC, Inc., with DeMeo Heating and Cooling as an alternate name and an A+ grade. On Angi it holds 4.4 stars from 14 ratings; on Google, 1 star from 2 ratings. A 2024 Google reviewer said they hired owner Eric DeMeo to replace an entire HVAC system, were promised a two-day install, and that the job took over 3.5 months and was never finished. That 2024 customer wrote that they had to hire and pay an electrician to fix his electrical work and hire another HVAC company to finish the system. A 2024 Angi reviewer said there was no paperwork and they lost all rebates the company had said it would handle. A 2024 Angi reviewer described an HVAC mini-split installation at their business and said Eric explained how to operate and maintain the new system. A 2023 Angi customer said Eric provided equipment options to fit their budget and household needs. In a 2023 Angi review, a customer said that while Eric was at the home to install a central heat and air conditioning system, he replaced the dishwasher's water shut-off valve and showed them an internal screen that needed cleaning.
this man put my family in danger by not converting the natural gas to propane and fried our furnace. This man is so irresponsible and is now hiding from facing what he did wrong. We keep reaching out to him but he won’t respond. Do not use this company.
DO NOT HIRE THIS COMPANY!!! If I could give a minus -100 stars I would. Nightmare scenario, incompetence, unprofessional, shoddy work, and the owner Eric Demeo is a HUGE LIAR!! Talks a good game, delivers on nothing. Hired to replace my entire HVAC system. Eric claimed to be a preferred diamond Mitsubishi contractor which was also a lie. Was promised a two day install, took over 3.5 months and never finished!! Left the jobs a huge mess, had to hire a roofer to fix a hole he left with a pipe dangling out! Nothing but delays and excuses. Tried to do electrical work on his own and he’s not a licensed electrician, I had to hire and pay an electrician to fix his failed attempts. Never passed inspection and he stopped responding to texts, calls and emails! I was forced to hire another HVAC company, BRIGGS MECHANICAL. Outstanding! They were amazing, They had to reset lines, install pans under units, reclaim all refrigerant, reinstall proper amounts, set and mount air handlers (he left the wobbly and crooked), rerun PVC piping, re-run pinched copper lines from splitter unit, install 3 kumo cloud devices which Eric claims were installed (no surprise, another lie). Overall a horrible experience. This is not all of it, there’s even more details that is not worthy of my time to articulate. I just hope people can see this review before hiring this pretender. Contractors like Eric give the HVAC industry a black eye. He takes no pride in his work and has a major lack of integrity!
Choosing Eric and his team for our HVAC mini-split installation at our business was a top-notch decision. Right from the start, Eric truly understood our requirements, suggesting an affordable and efficient solution, while ensuring we were kept in the loop throughout the entire process. The installation was conducted seamlessly, with the team demonstrating utmost respect for our workspace, leaving no trace behind once done. Moreover, Eric's detailed explanation on operating and maintaining our new system demonstrated their commitment and attention to detail. What stands out most is knowing Eric is always just a phone call away for any future support we might need as he is always responsive. I wholeheartedly recommend Eric to anyone looking for dependable HVAC services.
Customer service was horrendous.No paperwork and now I lose all rebates because they said they would handle it.I can't get anyone to answer me and now am out even more money.I would not do business with them ever again.Not all services completed plus no invoice
Very responsive and fairly priced. Went above and beyond to do a few small extra things.
