Reliance installed a new toilet in our ensuite. The service technician (Shawn) was awesome, friendly, courteous and truly cared about our environment due to the Covid-19 precautions. We were extremely pleased with the overall professionalized service. We would not hesitate to call Reliance for any of our plumbing, heating and cooling needs, they are truly the best service provider, Thanks Reliance👍🏻

Susan V

The repairman was so helpful. I was scheduled to have a plumber come in to snake a drain and it was going to cost $330!! Reliance offered me the plumbing protection plan and got a plumber to come this aft for a third of the cost!! I would definitely recommend Reliance for all of your home comfort needs!!!

Travis B

Recently replaced my hot water heater thanks to the help of Mike Morphy. He was very professional, knowledgeable and excellent to work with. The price was great and overall service was extremely timely. Thanks again Mike!

Tam D

Purchased a furnace and air conditioner with reliance. Because we had an oil furnace it was more work than a standard install however it was completed quick and efficiently. Our sales representative Brad Dunbar was great and friendly and very knowledgeable about the products that reliance has to offer Thank you Reliance.

Katie P

I dealt with Mike Morphy (through Reliance Home Comfort) when I needed to replace both my air conditioner and my furnace. He was knowlegable, friendly and professional. He cared about getting me the best deal and explained every thing fully to me; making sure I understood. He talked about the pros and cons about each decision I had to make. I didn't feel pressured into making a decision. I would highly recommend Mike Morphy.

Lareina R

Many thanks to the professional staff of Reliance! Our furnace quit working and they responded promptly and we were able to get our quotes and book an install quite quickly. We really appreciate all they did to help. We especially thank Michelle for taking the time to go over all our options with us!

Brian C

Jordan Dugas was the best sales agent my wife and I have ever dealt with. He was friendly, very helpful, and made buying a new furnace A/C a great experience. Business should always be this easy. Thanks Jordan.

Eric R

I have known Tony for several years. I had Reliance install a new furnace and air-conditioner at my residence in Brights Grove. Tony and his team were excellent. Professional, accommodating and left the property in excellent condition once the install was complete. Tony has followed up on more than one occassion; a true professional.

Rick B

Your Home Comfort Advisor, Michelle Bosch, was wonderful. She took her time and explained everything fully to us. She is very knowledgeable and caring. We are excited to have our new furnace and air unit installed. Thank you Michelle! Rick & Chris Barker.

Don D

Tim from Reliance was just here. Great service, straight to work and had my furnace up and running for me in under a hour. I highly recommend Reliance to all. I have exotic parrots that can not be without heat and this fantastic company has never let me down and very polite workers. Two thumbs up. Thank you Tim and Reliance.
