"I had a great experience with this company installing my new boiler. Their pricing was fair compared to other estimates I received. Dave walked me through the entire process and answered all my questions, and his team came in and did a great job with the installation. With so many scammers out there, I truly felt comfortable working with this company and will absolutely use them again in the future."

"Excellent job??????. Excellent customer service and very courteous. Left work area very clean and tidy."

"I paid an excessive amount of money to replace the heating system. The sales rep gave us comfort that everything will be done right and the two experienced and fully licensed professionals will be doing the work and that there is a no-excuse warranty, 1 degree guarantee, and 10 years on both the service and hardware. It just so happened that after the install, I told the installer I smelt gas and to check everything. He simply waved it off and said it's fine, give it some time. I told AJ Perri multiple times that there is a gas leak and I asked them to rectify the situation. I called them multiple times to send someone to fix the issue immediately and urgently, but they refused to commit to any resolution and won't send anyone until the gas is turned off for the whole building. I explained that its a condo and that the unit itself in the utility closet has a separate gas shutoff valve. Knowing this, they refused to remediate the gas leak."

"The old fence was removed; the ground regraded in several spots; the new rail post & rail fence installed including two gates. All the old fencing materials were taken away and a through cleanup performed. This all as per their price and performance quote."
