HVAC reviews in Manchester, New Hampshire

I have always shopped around and 80% of the time he is the best price. Also, there was a time this last winter I messed up and didnt reach out to get oil until it was almost too late. (Spaced it.) He was able to show up the next Monday and saved the day.
Really nice guy, and I have to say after that incident over the winter, this is where I go now regularly.

I was almost out of Oil after waiting nearly three weeks of waiting from another major provider who still didn't have an ETA for me. I called Lemay and they were able to deliver two days later. I'll ordering from Lemay going forward.

I got back from a business trip and the wife didn't keep an eye on the Oil level, and I was waiting over a week for a call back from another place. I got home and I was extremely low. Another Oil company, that didn't deliver to me recommended Lemay, and one other company. Not only did Lemay beat the other oil company price, he came out on the weekend to "beat the winter storm" we are about to get. His words when he arrived was "What else am I going to do? Sit at my house and not be productive?" I will be continuing my business with Lemay Oil Services. Very professional, as well!

Best service and nice to give a local independent the business. Very easy to do business with- they're like one of our nice neighbors who looks out for you. It was nice to stumble across them when we got frustrated with the company we did business with for years. We love the new calendar too. Nice touch.

I am very happy with Lemay Oil. Dan is a good guy, very reliable snd his prices are always one of the lowest if not the lowest around. I had used another oil company for many years. I ran very low on oil several years ago which was my fault, but my oil company said that it would be 2 weeks before they could make a delivery. I called Lemay's and Dan said he could come the next day. I've been buying from him ever since then.
Always great customer service.

Lemay Oil is great. Their prices are great and they are reliable and professional. I had a boiler issue and they recommended a repair services, HVAC Integration. These guys were also great and came out late Friday to repair my boiler. Thank Lemay Oil.

I needed an oil delivery, having bought a new house and not knowing where to get my oil from because I had never dealt with heating oil before. I decided to call these guys. They were able to give me the delivery I needed that same day. A few weeks later my boiler decided it wanted to give up and stop working, again not knowing who to turn to I called Lemay’s to see if they service boilers, they ended up referring me to a guy who was able to come out and get my boiler fixed that very same day. Can’t thank you guys at Lemay’s and Jack enough. Happy to have hot water again! Highly recommended.

Good company, Always Delivered and communication is great.

Had all the parts I needed in stock to fix my Miller furnace

My family has been coming here for generations. Truly one of the best heating supply shops in the region

I needed some parts to service my furnace, they had everything i needed and very friendly and helpful.

Tons of shiny things here

Great and reliable company! J A Marino Automatic Heating installed mini-split heating systems in my house, I’m extremely pleased with the entire process and end product. They excel in communication, cleanliness, and reliability. They were extremely respectful of my home and pets, and the fact I work from home and was there throughout a majority of the process. I would definitely recommend them for any work you need!

Nice people at the counter to work with. My first time there,many other supply houses. They're very friendly very knowledgeable. Definitely go back

My dad, Dave Corriveau brought me here when my furnace wasn’t running right. These guys can actually help you find the right parts. Support them and any Manchester business! You won’t regret it.

Very pleasant and professional to deal with. There the best at maintaining there stock.

Highly recommend Armstrong for heating vent and duct cleaning. Having been burned by previous unrelated construction work/service companies, I was hesitant but in dire need of help to clean out our heating ducts. From my initial consult w Joe where he answered all my questions, explained the process and reviewed photos of my particular ducts, I made a leap of faith based on his experience, knowledge and professionalism. His entire team was also highly professional, knowledgeable and nice. Price was reasonable and they did an outstanding job. We are going to hire them for some duct repair work bc they deliver what they promise and are trustworthy. Works for me.

Glad I researched and found Armstrong to clean my dryer vent.
Everything was straightforward and went so smoothly. The technicians arrived on time and meticulously completed the project. The cost was comparable to what I have paid elsewhere.
Shawn was polite and professional. I will definitely use them again!

Your home is not safe with this company. We had service done on 11/12/2025. I noticed that night that medical marijuana was missing from my bedroom. I am a cancer patient. I didn't notice anything else missing and didn't want to put someone's job in jeopardy in this economy. Today, I noticed that $150 was missing from my wallet. I don't get out much while I'm healing from treatment, so I didn't notice it was missing. I didn't think to check my wallet when I noticed the missing marijuana because it was right by the front door. Who would steal that audaciously? I called the company to report what had happened. I was told they had "received my email a while ago about the medical marijuana and had been passing it around". I never sent them an email, and neither did my husband. Someone else had also been robbed in a similar way. I was told I would receive a call after some "digging." On the follow-up, I was told that there was nothing that could be done, but they would cooperate with the police if I decided to file a report. No apology, no offer to reimburse, and no promise that they would work to prevent this from happening again. I was transferred to the owner, Joe, who offered to reimburse me $100 "out of his own pocket" if I wanted to come to his office to get it. That offer was rescinded when I expressed my dissatisfaction with it. I was told, "They are not the cops, and they can't interrogate their employees". I can't in good conscience be quiet when they are comfortable doing business this way.

This is very upsetting. How many will be robbed by a business that is being trusted in people's homes? There is no accountability, no remorse, and no meaningful effort to protect their clients now or in the future. Please look elsewhere for your family's safety.

The two technicians arrived on time. I showed them around the house and the lead technician explained what they were going to be doing. They made sure to take their boots off when they entered the house even though I told them they didn’t have to worry about that(we have hardwood floors throughout).
They worked fast and efficiently, and found some interesting things in my vents from when the house was built.
Overall we were very satisfied with the whole process.

I’ve been using Armstrong for over a decade. Always a pleasure & great job done cleaning dryer vents, bathroom vents, and HVAC vents. They do an incredible job & are always reasonably priced with no surprises.
