Glenn Hampoian Heating & Air Conditioning, Inc. says on its website that it has been in business 31 years. Its website lists equipment maintenance, a preventative maintenance program, equipment upgrades and repair, indoor air quality control, geothermal heating and cooling, and boiler service and installation. NH hvac license MBE1600506, held by Glenn Hampoian Heating and Air Conditioning, INC, is active on the state registry. A 2022 review said Glenn and his team were professionals who provided quality products and services. A 2020 review said that with them coming twice a year, the reviewer did not worry about the systems. A 2021 review says the company designed and installed the HVAC in the reviewer's new home, and that 8 years in, the reviewer found no wires labeled, a heat recovery ventilator not wired in, ducts that whistle and nothing documented. That 2021 review says that when the reviewer called for service, they were reluctant to respond and took a long time to figure out what was wrong. A 2020 review says the company came out to look at adding heat to a mudroom and basement and said a quote would follow in 24-48 hours, but after almost a full month and two voicemails the reviewer had not heard back.
Glenn and his team are true professionals and treat every customer as family. He's always there if you need him and provide quality products and services. I highly recommend him.
I made the mistake of contracting Hampoian to design and install an HVAC in my new home. Everything looked great, what do I know right? Well I am now 8 years in and I can say that I have discovered what a poor job was done. No wires labeled, colors used on wires are inconsistent across thermostats and dampers, some equipment (heat recovery ventilator) completely not wired in, ducts that whistle, nothing documented and if you remove the panels to see the lockout boards it is a rats nest of wires in the way to even see the indicator lights. It is no wonder every time I have called them for service they are reluctant to respond, take forever to figure out what is wrong, and always have vague answers. It is my fault for having contracted a fundamentally dishonest contractor and then sticking with them before getting a second opinion. It is in your best interest to seek HVAC help elsewhere.
Outstanding reliable service. With them coming twice a year I don't worry about my systems.
I contacted this company about adding heat to my mudroom and basement. They were really quick and energetic at first. They told me they could come out right away to take a look at the space and give me a quote. I was surprised since it was midsummer and I know they're busy with AC work so I thought this was great! I thought it was perfect. They came out on 7/30 and took a look at the space. It all seemed to go well and they left with telling me I'd have a quote in 24-48 hours. Then a week goes by and no response. I thought strange but okay it's the middle of summer and I'm looking to add heat. So I figured they were pretty busy. After a week of not hearing from them I called to check in on the status of our quote. They said they were busy which I suspected and I completely understand and would send it as soon as they could. I called them again this past Monday just to get a status update on the quote. They didn't answer so I left a voicemail. No response back. So I called again on Tuesday wasn't able to get through so I left another voicemail. I still have not heard from them to this day. They came out on 7/30 and it's now 8/23 so almost a full month. I haven't heard from them in three weeks. Highly disappointed since they were so eager at first. I'm pretty sure they've forgotten about us at this point.
Great HVAC company. We do business with Glenn and his team. Always a pleasure to deal with.
