Commercial and Residential HVAC Services

Heating, ventilation and air conditioning (HVAC) systems need to be properly maintained – plan ahead, not behind!

The highly trained team at CH4, a division of EPG workgroups (10 years), repairs, installs and provides maintenance on commercial and residential HVAC systems in the Greater Toronto Area all the way up to Barrie and Midland. While we specialize in Rinnai tankless water heater installations, we’ll work on anything to do with HVAC – from natural gas and propane to plumbing to forced air gas systems.

With over 30 years experience in the HVAC industry.

Available 24/7

CH 4 is committed to providing comfort to the area through straightforward HVAC installation, efficient maintenance and long lasting repairs. Our services are offered 24/7 to protect you from late-night emergencies. We understand that not everyone is interested in buying these systems, which is why we offer rentals and rent to buy options.

Above all, we focus on loyalty to the customer and a commitment to the quality of the services we provide. With our excellent workmanship, we go above and beyond normal expectations so we can guarantee our customer’s satisfaction.
