We had Nevon come today to work on some plumbing issues. He practiced very safe protocol re: Covid 19. He was very conscientious, considerate, professional and excellent work. Would highly recommend him if you need a plumber.
Kelly P
The plumber sent to our house to install our water softener was thorough, hard working and did an amazing job. I couldn’t be happier with the service we received. He was thoughtful of the noise as we have five small children. I highly recommend him.
Ricardo R
I called, to get a technician to repair my parent’s water Purifying system, they (Rocco P) and (keelam) did not just repaired it, but walked us trough all the reasons why this water purification system, broke down. I definitely recommend them as they are friendly and profesionals. Thanks, guys!
Tom S
The repair to my water heater was done quickly and professionally. The technician was very pleasant and explained the repair thoroughly and left the area as clean as he found it . I am extremely pleased with this service.
Matt M
My water heater stopped working today. It's a gas heater but doesn't have a pilot. The code said to contact a technician and since it's a rental I knew it wouldn't cost me anything. The two gentlemen that came were very friendly and professional. They fixed my water heater in about 15 minutes.
Sabrina R
The installers that came to my home, Matt ID #2843 and Curtis ID#3963 were outstanding! The were clean, arrived on time, worked great as a team and had my furnace and A/C installed without any problems. They set up the thermostat online for me and showed me how easy it is to use the app. They also cleaned up their work area. Matt and Curtis , thank you! 10/10!
Airi I

A great job by a great crew (Rob, Gage & Sam). Feel very fortunate that my new Air Conditioner & Furnace were installed by true professionals. It's a credit to Reliance that they have such good people working for them. Knowing my home will be providing me with ideal comfort for all seasons for many years to come gives me such peace of mind. Thanks to one & all at Reliance for a great job & experience.

Meet our St. Catharines Team
At Reliance we take pride in educating our customers in how to check your home for leaky faucets, sinks or showers. Extra water costs from pipe leaks can unnecessarily increase water bill costs. Sometimes a small leak from a bathtub can be a sign that a larger problem might exist behind tiles or bathroom walls. By inspecting your shower, bathtub and sinks regularly for unusual colours, noises or odours you can detect a minor leak and get it repaired before it becomes a costly problem.
Calling us for a new air conditioner can also be delayed if you follow general energy-efficient practices like planting tall bushes and trees near the house, using your oven less often, turning off lights when you leave a room, and ensuring your window blinds and curtains are closed during times you aren’t at home.
At the beginning of the winter months, ensure your thermostat is set to heating from cooling, check that your furnace switch is turned on, and check your air vents to make sure that the air passages are clear.
One reason is that we’re committed to St. Catharines and the surrounding area – because it’s our home, too, so every member of our team understands the unique needs that come with the humid climates created our proximity to Lake Ontario, Lake Erie and the Niagara Escarpment. Rest assured, we’ll help you find home comfort solutions that keep you warm in the winter and cool in the summer – and comfortable all year long.
You can also be completely sure you’re in good hands with our friendly and knowledgeable Home Comfort Advisors, specially trained to help determine the best equipment for your home, whether it’s a furnace, air conditioner or water heater. They’ll outline all your options and provide the knowledge you need to make the right decision.
Finally, Reliance Home Comfort™ offers a range of brand-name furnaces and air conditioners, including our own SmartAir™ line, as well as Carrier®, Goodman® and Amana®. Not sure what’s best for you? Our team in St. Catharines is here to help.
We work with top name brands including: SmartAir™, Amana®, Carrier®, Goodman®, Rheem®, Rinnai®, Viessmann®, Weil-Mclain®, Bosch®, and Nest®.

What I Love most about being an HCA is the interaction I have every day with homeowners. I get a gratifying feeling helping them find solutions to their concerns in regard to their home comfort and safety. Following up with the customer and seeing the joy it brings to their lives after doing business with us is the icing on the cake. What I Love about working with Reliance is what they promise is what they deliver, and they are willing to go about and beyond for customer satisfaction.
