Nate was very professional, offered proactive upgrade options without being pushy. Was incredibly mindful of maintaining COVID protocols and rectified our service problem in a timely manner.

Khuram R.

Experience with Reliance is excellent and amazing so far. Mr. Malik Riaz came to fix my Furnace issues & John came for Plumbing. Both are very professional and friendly. I would strongly recommend Reliance. Their plans are very good

Carol R.

Had new furnace & a/c installed. Kept well informed which I appreciated. Installers were polite and very careful and neat. Explained about new equipment so we new how to use it and programmed nest thermostat for us. Extremely happy with this purchase and install. Thank you!

Shelley R.

Kris has been to my home on a few occasions for my plumbing issues and as a first time home buyer with little experience I found the level of honesty and expertise that he provided to be both amazing and appreciated. I would recommend his services any time! Thanks again.

Cleea S.

These guys were very knowledgeable and top notch. Even corrected items over and beyond their duties. AC was done today. Thankless water heater and furnace last week. AC was the smoothest. Mike, Andrew and Justin, thank you so much.

Samir C.

Got a Water Softener from Reliance and works great ! Haven’t bought a bottle of water for over a year now and I’m so happy to know that I saved many Turtles. Much appreciated Jordan!

Monika A.

Luciano and Adam were a pleasure to work with. They explained everything to me and even when I needed help working my nest thermostat they came out and showed me again and made sure my dampers were open and everything was working properly. Thanks guys for all your help. Chester and I both appreciate it.

I believe that my experience both in sales and management give me a balanced approach to recommending the ideal heating, cooling and water heater for your home. I grew up in Peterborough and went to Thomas A. Stewart High School. The family and friends I have in the Kawartha area, and of course the lakes and rivers, have kept my heart here. I have a son, two daughters, two grandsons and family is important to me. An avid outdoors person who enjoys a good game of golf or tennis, I also love to see the Jays or Leafs if I can get tickets. What do I enjoy most about being a Home Comfort Advisor for Reliance? Simply, to be able to share my knowledge of this business with home owners and help them get the comfort, efficiency, reliability and support that comes with our products. It's very gratifying. I'm happy to help you with your furnace and air conditioning needs any way I can. Please call me at 705-933-8880.
