Christopher Gale and partner were very helpful and kind. They were on time and explained everything in an easy way. Love doing business with Strogens.
Very professional service
Strogen's was very professional and worked hard to get my new boiler to the basement during the winter. Not a complaint was heard! They finished putting in my new boiler in one day even though it was a long one! I would definitely recommend them.
Very professional technician
I had a clogged boiler and my technician was Henry Jeffrey. He was very professional in conducting the cleaning, and he ended up replacing an ignitor and kept me informed on what’s going on. He cleaned up after, and I was very happy with the job he did.
Professional, Prompt Service
Professional, prompt service from all the new install technicians. Thank you, Steve M., Ryan K., Brandan S., and Cody. Outstanding job by all.

2026… Kyle Smith helped us to understand how our water heater reacts to the ultra-cold weather we’ve been having, and adjusted the unit for us; he also made some suggestions that we may order in future.
Everything Is Working Great
Henry was on time and very polite. He explained what he did, and everything is working great. Thank you!
Derek and Chris did a great job
Derek and Chris did a great job. Also sold me a membership, and I’m thinking about a humidifier.
Ted was very nice
Ted was very nice, professional, and knowledgeable. Plus, he didn't try to sell me anything.
She Took Really Good Care of Me
After writing my review, I called Pro Customer Service and spoke with a very nice representative, Haley, who took really good care of me and getting a service pro out to me today. She was very understanding of my needs and actually let me vent without interruption and listened to me. She informed me that she was still working on this issue after my first call. I feel bad that I gave a bad review after talking with her. I wanted to thank you for her customer service skills and making me feel like a valued customer. I hope she gets rewarded for her awesome customer service skills!
Very professional, very friendly
Ted Tremblay has serviced our furnace a few times. Very professional, very friendly and knowledgeable. For future services, we would love him to come back.
Ted was great.
Ted Tremblay came to the house to help figure out my furnace noises. He wasn’t here long and was able to resolve the issue. Ted was great and great to interact with. Shane was with Ted and was great too.
We're Always Happy with the Service
Thank you so very much for addressing our issue about our damper. Raymond was truly the best in going into our attic (very tight in space) to see the concern, as well as the other gentleman with him! We're always happy with the service we receive!
All Fixed Now
Heat went out on December 23rd and a technician was out the next day. Wound up having to order several parts which did take some time. Heat was restored prior to a very cold spell but went out again. Another technician came out and found another part had failed. He was able to get the furnace started so I did have heat. Ted returned the following week and installed the part and it's all fixed now. All the technicians that came out were very professional and knowledgeable. Thank you all very much.
Outstanding in Every Respect
Chris Gale, Strogen's tech, was outstanding in every respect. Highly knowledgeable, very friendly, went the extra mile troubleshooting our system, just a complete professional. Thank you.
5-star service this afternoon
Thank you, Kyle Smith, for his 5-star service this afternoon. He was punctual, polite, and efficient. Plus, he likes dogs, which is always a bonus!
Derek and Chris did a great job
Derek and Chris did a great job. Very capable, very personable. 5 stars.
Outstanding HVAC Technician
Chris G is an outstanding HVAC technician. His technical skills are excellent, and what really impressed me was his ability to think outside the box and solve problems others might miss. He took the time to understand the issue, explained things clearly, and delivered a smart, long-term solution. Professional, knowledgeable, and dependable—I highly recommend Chris G.
Once again, Strogens came to the rescue
Once again, Strogens came to the rescue on a snowy Sunday afternoon. We had a frozen pipe that fortunately didn’t burst, but they left us a couple of space heaters. Everyone I have ever spoken to is so professional and helpful, especially the technicians. And as a sidenote, the service agreement is so worth it!
Our Technician Ted Deserves 5 Stars
Our technician Ted deserves 5 stars! He was great and got our heat and hot water back up and running. We were not happy with calling for emergency service. It was brutal cold and we waited 2 days with no heat. Even Ted said that was unacceptable. We were under warranty, too.
My experience with Strogens is top notch
My experience with Strogens has always been top notch. Kyle Smith came over to do our annual check-up/cleaning and was very kind and professional and answered any questions I had.

Impressive Repair Service
Impressive repair service for a malfunctioning valve on our furnace. Brittany and Derek were professional and helpful this morning. Very pleasant. Brittany came to our house for an emergency assessment two nights ago and discovered what was wrong. She is definitely knowledgeable and explained how we would remedy the issue. It is reassuring to see young women working in this repair service. Also, a shout-out to customer service for scheduling our service repair. Very helpful to get the updates about when the technician would arrive. Thank you.
Extremely knowledgeable and patient
Brittany was extremely knowledgeable and patient while troubleshooting the problem with my furnace. Even after she fixed my furnace, she stayed to make sure there were no issues.

I don't typically post reviews, but I found my technician, Brittany, deserving of a shout-out. She's knowledgeable, professional, and personable. She kept me informed of her progress and findings. I don't usually make requests for specific technicians, but will definitely be requesting her in the future.
