My gas forced air heater was not working and i got a recommendation from my plumber for HGH. It took a week for them to come out for the initial service. Jeff took a look on Friday. The motor for the fan needed to be replaced. He expedited pickup of the new part and just finished up the work. He made sure to squeeze me in because it's getting quite cold. Jeff was quick, efficient, and a helluva nice guy. I'm very happy with the service i received and would absolutely work with HGH again! read more

We've used HGH many times over the years. The most recent was also the most ambitious - converting from oil to gas furnace. HGH did not disappoint. From Mark's initial visit to prepare the quote (his was the most thorough of the visits of the 3 quotes we got) to actual installation, it was seemless, very professional, and we couldn't be happier with the result. The price was very competitive also (almost $3000 less than the most expensive quote for the same Rheem system.) read more

HGH and my contact Manny did a great job preparing estimate options, and answering my questions as I went through the process of comparing estimates from different companies. The AC/heat pump installation went very well, not a single issue. I love the ecobee app they use that is installed on my phone so I can schedule the house temperature or change it from where ever I am. read more

Jim at the team at HGH has done great work for me in the last couple of years. First I had them run gas lines to look up a gas fireplace and they did a great job. Great communication, prompt service and you can tell they know what they're doing. Recently, I had an ERV installed on our home and they did a great job with installing it and answering my many questions. I definitely would recommend. read more

My furnace stopped working, they came right out to work on it. Fixed it in no time. They have reasonable pricing, too. Would highly recommend this company. read more

The HGH team from start to finish were excellent. In three days I received an unbeatable estimate, an inspection by company owner, and efficient installation of a new heater, chimney liner, and pipes. They exceeded expectations by improving the exhaust vent and installing my replacement thermostat. Exceptional quality, value, and workmanship! And nice, too. read more

Grateful to the staff! When I called at 06:30 am Monday morning Stephanie was a pleasure to work with! Jeff arrived timely and did a great job! He's a smart person! We've been using HGH for years! They installed both the heating system and created an air conditioning system in a 1924 era home in 2008! Always satisfied with everyone we've dealt with! read more

They installed a new air conditioning and heating system in my condo. The estimate, pre-service representative and the installation were all prompt. The installation went smoothly and took less time than other companies who installed the same system in the condo buildings. The cost was less than any other estimate. It has only been a couple of days, but everything is working well. read more

Air conditioning in the house needed servicing. Another company I called, that I had used multiple times in the past, was not very responsive. Called HGH and had a technician at the house the next day. Unfortunately, AC system needed to be replaced. I believe I received an honest quote from HGH. Service was completed to my liking and have had no issues since having the AC installed a couple months ago. Will definitely be calling HGH in the future for all my HVAC service needs. read more

I've been using HGH for almost a decade. My parents use HGH. I refer all my friends to HGH. They are fast, responsive, reasonably priced, and don't over-sell you anything. I have had them service existing units at properties I bought, and have had them install two total hvac systems in two properties. I have no complaints. If you are thinking about getting a service contract, you should hire HGH. If you are thinking about getting a new HVAC system, you should at least get a quote from HGH... and then hire them. read more

HGH is the best HVAC company we have ever used. Jeff is a wizard at diagnosing and fixing problems we've had with our boiler and thermostat. Their prices are very reasonable and everyone we've dealt with has been helpful and friendly. We recommend them without hesitation. read more

HGH Mechanical in Edgewood was a great company to work with last week. Manny arrived to my house to look at the job I needed completed exactly when he said he would. The estimate arrived the next day. His team completed the jobs flawlessly and also on time. His techs went above and beyond to be sure everything worked and cleaned up all materials before leaving. Outstanding work and friendly customer service! read more

I have been a customer for over 20 years and referred many people to them. I own three different properties. Maybe they've grown too much to offer the excellent service they used to provide. The service from the technician and then the sales guy was so unprofessional. I needed a new system ($7,000). I went with another company because I was dissatisfied with their service. You think someone would have followed up since I'm a long time customer and needed a whole new system. Nope. They only sent their invoice for $132 for their service call. Guess they would rather have $132 than $7,000. read more

We used for years without an issue until this year. Now being told they had some employee turnover. AC wellness check done in June, no issues with the system. August, began with AC issues, they came out said the system was low on coolant, they charged an exuberant amt for coolant, this did not resolve the issue. When I called back 3 days later they advised we had a leak and all the coolant probably leaked out. I inquired as to why they would recommend adding $500+ in coolant without disclosing the leak and the possiblilty we could lose the coolant in a matter of days, the person on the phone advised, "this was above her pay grade", she would take the message and have someone call me back. That never happened. I spent the next 6wks sending emails and calling to resolve the bill with no response. Then today I finally reach the same girl. She advises they have no record of us calling them back with a problem so they assumed everything was okay. They blame it on the guy who left and basically will not work with us to resolve the issue. Will NOT use them ever again! read more

I called HGH for AC service/maintenance, but then had some water start backing up into the room, so I asked to move up my appointment. They were very accommodating and it was a relief to have the issue taken care of quickly. Chris showed up during the scheduled time and even sent a text that he was on his way. He seemed very thorough and completed the work promptly. I was very impressed by this company and for a fair and reasonable price. read more

After being a customer of 10 years, I will no longer be their customer. My furnace stopped working. It took two days for someone to come out despite the fact that I have a service contract. The technician who arrived advised me that I would be better off buying an entire new furnace instead of replacing the part. After researching, the part actually cost half what they were charging me, and was covered under warranty, and would not have cost me a thing. Echoing someone else, it doesn't matter how nice a thief is, they are still thieves. read more

Some 24 years of great service, HGH is still our go-to. They installed this old house's 1st central unit. Two boilers and a hot water storage tank later, we invited them back to replace our 24-year old Central AC unit. They are always professional, responsive, and reasonably priced, with all installations and maintenance, while considering all options. https://hghmechanical.com/ read more

I researched HVAC companies before deciding on HGH. They came in early July to diagnose and repair split system previous homeowner installed in 2020. I was told the mechanical fittings weren't tightened properly which caused the coolant to leak. Apparently, this caused my system to have zero remaining coolant and I would need twelve bottles. This would cost approximately $2000. Then in mid-August, my split system was again not working properly. I called HGH and was told that high winds can loosen the mechanical fittings which surprisingly resulted in low coolant. I was informed a leak was found, and repaired as well as a further test to ensure it was repaired. This time I was charged $750. Luckily, summer was over so I stopped using the splits for ac. I tried to use them last month for heat, and get this, completely out of coolant again. I learned my lesson and didn't call HGH this time. If you have an indispensable income and want to continue to pay without addressing the issue call HGH, otherwise stay away from this company. read more

Really helpful nice experts, who showed up promptly and installed our UV lights too! They also were careful with our home and our COVID precautions Thanks so much. read more

I recently engaged this firm for the first time. As my Wife and I renovate our home, our gas-log fireplace required repair and equipment replacement. HGH Mechanical was recommended by the equipment supplier. HGH replaced the gas line and provided for the gas hook-up to the new gas-log system. Matthew and Christian, the HGH technical professionals who completed the job, were extremely professional, polite, and competent. Pricing was very reasonable. I highly recommend HGH Mechanical for your consideration if you require gas-log work performed in your home. Joseph read more

We got a new HVAC system in December 2018 and recommended HGH to my 85 year old mother when her AC went up a few weeks ago. Special thanks to Nate and Adam for crawling around in her attic and getting the install done on one of those incredibly hot days. She's very happy with her new system, the price was reasonable and the work was done promptly. We recommend HGH to all of our friends and family! read more

I just had a high efficiency heating and air conditioner installed and could not be any happier. the price was great and the service was perfect. they were on time and when they left the basement was spotless. Phill and Jim were great to work with. I would use them anytime. read more

We needed to replace our 25 yr old A/C unit. We looked no further than HGH. Matt and Chris, arrived on time, wearing masks. They did an expert job installing our new unit and removing the old unit, including clean up. They spent time answering questions about the system and the humidifier. Both gentlemen were professional and friendly. Many thanks to Jimmy, Matt and Chris, as well as the family members who recommended HGH. read more

We had the exact opposite experience of this other reviewer. We were referred to HGH by a friend of ours who is a construction engineer/project manager who uses this company often. From the beginning to the end, they were great. Ross, who came out to give us the estimate (we got estimates from 3 companies) was well-versed and truly didn't try to oversell us on a system (we were getting a new furnace, hot water heater, humidifier, and AC unit for outside) and actually steered us away from a pricey dual fan system that we had been considering and that wasn't necessary for our small cape cod home. Manny, who came out to scope the job once we signed the agreement, was also thorough, nice, and easy to work with. When it came time to schedule the job, as we were edging up on the coldest weather of the year (polar vortex! Minus 15 wind chills!) and snow still on the ground, Manny gave us several options of dates for install and was understanding as we flip-flopped on the date that would work best for us, which was appreciated. On the day we had scheduled, the installers showed up ON TIME (between 8-8:15am...when do you get that precise of a window of time?) and ready to go. The four guys who installed our new system were super nice, efficient, and even loved on our misbehaved, attention hungry dogs whenever they had the chance. Goodness gracious, the one gentleman even taught our new dog to give him her paw! The installation went very smoothly and they were clean as could be. As a matter of fact, after they left, you couldn't even tell they'd been there except for the beautiful new heating and cooling system. They even nicely went the extra mile to figure out a solution to keep water from dumping into the furnace from the floor above if the toilet ever overflowed. I know that sounds wacky, but we'd had it happen before and it was a very expensive (years ago...not fixed by HGH) fix, so we'd learned our lesson. Lastly, the price. As I mentioned 4million words ago, we had shopped around. I work in procurement, and know the importance of getting several quotes. HGH came in over $1800 less than the other guys thanks to Ross not overselling us a system too big for our home, and just great pricing. Needless to say, we will be referring everyone we know to HGH in the future, as nothing is more important than personal experience with a company, and our experience was top notch. read more

From the initial phone call trough the entire process all went so smoothly. Very professional but personal. I wouldn't hesitate to call again and or recommend read more

I returned from a European Vacation to 87 degrees in my house. The a/c would not come on at all. I called HGH Mechanical and Chris Rotundo was at my door within 45 minutes. He was fast, friendly, and fixed the problem. I will use HGH for my future hvac needs. A+ read more

Just had a new AC unit installed in my parents home with HGH and we couldn't have been happier. The price was great and the work was first class. Nice guys, too! read more

We called HGH Mechanical, as we returned home, late at night, from a trip to Maine to find our 3 year old A/C unit and thermostat not working. Our neighbor said that there had been a bad thunder storm a couple of days before we returned home. HGH was very responsive and came right out the following morning. Christopher Rotundo came in and completed the repairs within 1 1/2 hours, and that included servicing the entire system. We were so impressed with Christopher and his work. He was friendly, professional, did a fantastic job, and all with a reasonable price. We asked if HGH offered service agreements and he told us to go to the web site and decide which service agreement we preferred and then call or complete on line if we wanted one. Christopher did not try to push us into an agreement at all and we really respected him for that. He represented HGH so well we are going to purchase an agreement right away! read more

HGH did a great job replacing my heat pump system. They will not over sell you on a unit. They came recommended by 2 different people I work with and I was very pleased with the whole process. We agreed to go forward with them on Tuesday, they measured on Wednesday and could've put the system in Thursday but Friday worked better for us. Fast, efficient, friendly and very reasonable compared to other estimates. I love a company with good service! Thanks HGH.....Oh, and it's much warmer than my old heat pump:) read more

2nd time I've called them for AC problems. Great experience both times. Called this morning at 7 and they were here by noon. It was a quick and easy fix and then the technician gave the whole system a once over to make sure everything else was in order. He was done and gone in no time and the price was absolutely reasonable. I'll definitely call them the next time i need AC or heating work done. read more

A/C needed a run capacitor (a $5 part) a couple years ago and these guys charged us $250 to replace it. Doesn't matter how nice a thief is if he's stealing from you. I'm fine with people making a living, but that was crooked. My wife called him on it and he got nasty with her. I will never deal with them again. read more

Do not use this company. They came out to our house several times to install HVAC in our new addition. The first few visits they left their trash everywhere and did not clean anything up when they were finished. Coffee cups and trash left in the driveway and in the room they were working on. Trash left outside next to the unit they installed. I thought that was bad until today when I returned home (8 1/2 months pregnant) and found that they had been smoking in the room that they were working on. This is the room that will be our new master bedroom and the room that we will be sleeping in when our new baby arrives in a few weeks. Worst customer service ever. read more
