Jason the Reliance electrician was so professional and courteous. From the time he arrived, he reviewed with us what he would be doing including letting us know all the Covid 19 health and safety precautions he will be taking for his and our safety. He was thorough in his work and explained what he had done to fix our electrical issue and what other services were available to us. All in awesome service call!

William C

I had some water leaks in my kitchen faucet and bathroom. The Plumber showed up on time and was very thorough in fixing every problem. He performed his work in a very professional manner and was very polite. I would highly recommend this service to my friends and colleges. Thank you very much Reliance for your service.

Mavis D

Already a customer with Reliance on other products. Received information from their Water Purification Advisor Kerilee for Reverse Osmosis and Water Softener system and was happy with the knowledge and professionalism . Answered all our questions and was able to explain the different options in a way that made sense to us. Thanks again for the wonderful service!

Noah A

Chris was great and very fast. Super respectful during a weird time in the world. Incredibly professional and Reliance was incredibly fast at getting this done. Day 1, Al comes in decides to replace the water heater, Day 2 Chris is there putting it in. Not to brag, but now I have hot water so... pretty big deal.

Vicki D

My condo board asked all units replace older water heaters. I put a call in on Saturday and made an appointment for Monday. I thought they were going to make another appointment to replace it, but they were able to replace it same day. Very happy.

Dima K

Great service! Our tech James Walton was very professional, fixed the issue right away but also investigated further and improved the performance of our furnace. Took the time to explain everything. Went above what was required and replaced worn out parts that were about to fail. Thanks!!!

Ray G

Every technician that comes to service my furnace has been amazing. They are very professional and walk you through what they are doing. I strongly recommend their protection plans. It’s saved us thousands.

Kevin G

James went above and beyond to help get my furnace working again. He knew exactly what the problem was and got it fixed very quickly. Really impressed with his service and professional attitude.

Robert D

I placed a call for service as our furnace had stopped. Within 20 minutes of my call, Reliance had a technician out. Our technician, Tony, was amazing. Prompt, knowledgeable, and professional. He had the problem fixed for us, including replacing a part, and we had heat again. Extremely impressed with Reliance.

Nadine R

The service technician was thorough in his investigation, communicated clearly his process and logic, and competently repaired our furnace. He went above and beyond by replacing the filter and adjusting the settings on our thermostat to improve efficiencies. He was also friendly and polite. Everything was resolved within three hours of us making the service call! Thank you!
