REVIEWS

“Superb Professionalism!”

“Called HGH for a second opinion. The other company had diagnosed a $500 repair, but Phil solved the issue immediately…. and only charged the service fee. Superb professionalism and customer service!” —Mike Jacobson

“Saved Me a Bundle!”

“Matt just saved me a bundle by correctly diagnosing the problem and solving it for a faction of what I was expecting to spend. Did not even charge me for the part they ordered and did not need! Highly Recommend.” —Bill Greskovich

“A Fair Price…”

“I reached out to HGH after the contractor that my home warranty assigned to me never showed up or called. Phil was courteous, professional, and gave me a fair price that was lower than my home warranty’s deductible. I highly recommend HGH!” —Aleksey

“Most Competitive”

“Replacing an aging AC unit, they offered us the most competitive quote. They recently came out with same day service for no additional cost. Our tech DJ was super-efficient, polite, and professional. I highly recommend HGH Mechanical.” —Ivan Borissow

“Outstanding!”

“As usual the team from HGH (Adam, Tom, & Chris) were outstanding! The installation process for our new HVAC system was painless…we could not ask for more. The HGH team has always treated us right!” —Richard Barton

“Recommend 100%”

“I was very impressed by their product and everything else. Did a great job! Very nice people and price was better than the other two quotes I received from other companies. Trust me, they are very good!!!! I recommend 100%.” —Richard Perez

“Professionalism”

“We recently had our upstairs unit stop working on us. Nate and his crew were able to install the new unit in our attic without issue and great professionalism. Thanks again for making this entire install and purchase go smooth.” —Paul T Burton, State Police

“Excellent Service”

“Excellent service. Fuel oil furnace & heat pump residential install. I got about 5 estimates and I interviewed all the contractors. They came on the scheduled day, worked fast, and cleaned up when done. No problems.” —TJ Dickens

“Amazing Job”

“Jimmy, Phil and their team did an amazing job on the removal of our old boiler and the install of a new one along with a hot water heater. Seriously, the install looks like art. I highly recommend them and will be passing their name on….” —Nicholas Griner

“Affordable & Honest”

“I wasn’t sure if my heating unit needed to be replaced or repaired. DJ came out and after a quick fix said everything else was in working order. These guys are professional, affordable and most important honest.” —David Resnick

“Never Going Elsewhere”

“This is the second time we have used HGH Mechanical. HGH responds quickly and the prices are extremely reasonable. We highly recommend them and we will never consider going elsewhere. Thanks DJ and HGH Mechanical.” —Wendy Chaney

“Charged Less”

“My heat not turning on. I saw recommendations for HGH so I gave them a call and they came out the next day, got everything fixed and charged less than other companies quoted us just to diagnose the problem. Will definitely be recommending to everyone!” —Britt Johnson

“Reasonable Price”

“Heat went out last night. Called HGH at 9 AM today, heat pump was fixed by 10:30 AM at a reasonable price. No complaints whatsoever, will definitely be calling next time we have HVAC needs.” —Adam Bauer

“Tech Was Excellent”

“We called and they were at our door in less than 24 hours. Our tech Christopher Rotundo was excellent. HGH is a highly respected organization that I would highly recommend to anyone with heating and/or AC needs.” —Sarah Lambeth

“Within an Hour!”

“My AC unit was not working properly and I called HGH for help. They had a tech at my house within an hour. Chris was very professional and extremely helpful. He repaired the unit within an hour! I’m a very happy (cool) customer!” —Ramona Birkmaier

“Thanks a Ton”

“No heat, next day appointment in the morning to mid afternoon, great knowledgeable, in an out less than an hour and a half and we now have heat on these cold days. Thanks a ton.” —Dante Guzman
