Laura P

The Service Provided By Reliance in Thunder Bay was top notch! They were fast, friendly, and on time! Dennis and his partner were quick to locate the plumbing issue and even went out of their way to find other potential issues. Dennis gave great advice and fixed the issue quickly. He tested everything before he left and even looked at an issue that wasn't the main problem! I highly recommend the team at Reliance!

Nikki M

We have always had great service with Reliance and have used them for our furnace, water heater, reverse osmosis system and plumbing issues. Even when they had a tech sick, they were good about calling right away and rescheduling. Dennis and Bernie are fantastic guys!

Annamarie C

Outstanding service! The technician, Dennis M. was very knowledgeable and friendly and fixed the issue with the hot water heater. He explained every detail along the way. A very positive experience. Thank you.

David M

Installation of my new water tank was quick and efficient. Julian Lisicki and Dan Spooner did a great job on the installation and left my basement as they found it. They answered all of my questions, and left me feeling confident with how to operate my new new water heater. I am very happy with the service they delivered.

Kelvin S

Dennis arrived on time ,was very friendly and helpful in explaining what was going to be done. The water tank change was completed far faster that I anticipated. He suggested other reliance products to deal with my hard water problem. Job was done quick and clean. Very good overall experience.

Drasti B

Reliance Mackenzie was very prompt in their services; they understood exactly what we wanted when our water heater broke down. The technicians, Gagan and Paul, were very hardworking and finished their jobs with attention to detail. Matt, the operation manager was also very helpful with our requirements and made sure that we were happy with the final install. They have a solution for everything. Definitely recommend!

Pamalla K

We had a great experience with Reliance, the guys were knowledgeable and explained everything they were doing. They were so friendly. I would definitely recommend this company to friends and family. My new furnace works great.

Reliance was quick to assess, repair, and then install new furnace. Salesman Vince discussed products and options, conferring with the ‘shop’ guys for particulars to select best option for my corefloor home. Installers were there the next day, Chris and Brent, explained the process, answered questions readily, and completed install quickly, and gave instructions on new system. Great team, definitely recommend them to anyone.
