J & S Heating And Ai

Your Comfort Professional in the Niagara Region

J&S Refrigeration Co. Ltd. was formed in 1956 by Mr. Gord Jenkins and Erzel Snetzinger. It was a small company with only 3 trucks and 3 servicemen to serve the St. Catharines area. J&S primarily looked after commercial refrigeration, heating and cooling and farm cold storage needs.

We Expanded to Serve Your Residential Heating and Cooling Needs

As technology changed and modern times approached, J&S changed as well. In 1974, new ownership saw J&S expand to serve the Niagara region. We also expanded our services to include residential heating and cooling and changed our name to J & S Heating And Air Conditioning.

Service is Still a Top Priority for J & S Heating And Air Conditioning

J&S was founded during a time when serving the customer was the top priority. Sixty years later, that tradition continues. J&S continues to serve the Niagara region as an authorized Carrier® dealer, providing sales, service and maintenance to both residential and commercial customers. We strive to exceed your needs and expectations on every job. You won’t be disappointed.

Free Maintenance Advice

I called to request a service call/estimate to correct a problem I've had for more than two years. After having another come to replace a motor on my furnace, the motor has run continuously. This has caused enormously on our electricity bill. The staff who answered helped me fix the problem with a few quick instructions. No fee, no need for service call. What a huge relief. Thank you J&S for your honor!
