Groulx Mechanical Heating & Cooling Inc

Groulx installed 2 new AC systems + furnace + whole-house humidifier for our home and 2 new water heaters in 2022. Before the install, Mark serviced our old units (20-years old) and helped us keep them alive a little longer, giving us insight into when we would probably have to fully replace.

The installation process from selecting units through the installation process was great. Mark educated us and gave us informed choices to make. The installation cost was MUCH more reasonable than some of the other quotes we received.

Ana is excellent on the phone with scheduling whenever we had to call. We are now about a year past install, and Mark has provided excellent service after the sale, too! Mark has come out a couple times in the past year to tend to minor issues with our new systems and he didn't nickel and dime us - the follow-up visits were done at no cost to us since the units were new, which I really appreciated. I really appreciate the work Groulx did for us - they've earned us as customers for life.

Groulx mechanical is honest and professional. Every time they come for maintenance they never upsell us anything. They have been our go to for HVAC for over 10 years. We trust their work and have never come across any issues. I will use them over a big box company any day. They installed our new AC unit about 6 years ago and we have been extremely happy.
The prices are in line with quality and the personal attention from the office staff is superb. Being able to trust someone in the HVAC business is a relief.

Mark was so helpful and responsive and went above and beyond to help us when we found out that the previous owner of our new house withheld info about the damaged 5-year-old AC condenser. He tried to get it covered under warrantee and did everything he could to help us out.

He was able to come install a new one within a week and was a pleasure to work with. Highly recommend.

Mark, installed new dyer vent cleaned out the dryer of all the lint that had accumulated over the years with the old vent setup. Did in the time they stated cleanup any messes made. Everything was nicely done. Thank you

I thought I would try one of those businesses that are advertised on TV everyday and recommended by good old boy "Tom Martino". First of all it was very hard to get them here. Well when I finally got them here he said it was to cold to work on and check out my A/C. It took 2 more weeks to get them back. He cleaned the unit outside and told I was going to need new motor for starters, then he said that it was leaking somewhere and that the fee to fill the system with a dye to find the leak was $1400. Then he said it was about $1000 to fix the leak if was even repairable. And then to charge the system with refrigerant was $400-$600 a pound. Basically it was going to cost approximately $4200.00. I said I would give it some thought.
Well I already knew what my answer was, NO, HELL NO.
I looked on Nextdoor and did some research and found Groulx Mechanical so I called and left a message on voicemail. Well within a few minutes
Mark returned my call and came to my home and I told him what Fixit24/7 told me. He took a quick look and said that he would come back on Wednesday to get it fixed. Well I had a Doctors ppointment at 10am. He had called at 8:30 and asked if he could come by early but I told him I had a Doctors appointment at 10am told him about my appointment at 10am and he said no worries. As soon as I was done at the doctor I left Mark a message and he called back immediately. We agreed to meet at my house asap. When I got home he pulled up and said he would get right to work on it. About 20-30 minutes later he told me that he was finished. 👌 That was fast. He recharged the system and put in a sealing agent, told me the motor was fine, that he didn't believe that there was a leak and everything looked good. And the price was $835. Perfect.
Groulx Mechanical is a small family business and an excellent business. Communication is excellent and that is the most important thing to me. Very honest, prompt, and not trying to sell me things that don't need replacing at ridiculously high prices.I also own my own business and never do I try to sell customers things they don't need. I HIGHLY RECOMMEND GROULX MECHANICAL. Treated me a customer and not an ATM machine.

I used this service the summer when my Air-conditioning whet out and had tremendous service at an unexpectedly reasonable price. Their honesty and fairness gave me a feeling of security and safety that. Trust is a priceless and I'm so greatfull that I found them. Today my heat went out and again they arrived quickly with the same great experience. They will be my only call always.

Mark didn't stop until he fixed our furnace! We have had numerous negative experiences with contractors over the years and Mark renewed our faith in receiving quality work. He is communicative and competent. We would definitely call him for future needs.

We have used Groulx for many years. They replaced our AC and furnace system at a great price, Great response time, Mark and the crew are very knowledgeable and helpful. Always respond to questions and concerns, and they actually answer the phone!

Mark is an exceptional person and a highly skilled technician. Thank you for your continued service and your kindness! Thank you too Anna! ❤️

Very knowledgeable and courteous. Reasonably priced. I really enjoyed working with them.
