We had a really great experience with them. Very detailed, professional and friendly. We really appreciate that they cared about our well being, asking us not to go upstairs for two hours so that the chemicals can settle. Afterwards, we were advised to wipe everything down.
Quick response to my request for a new AC unit. Jack came the next day and did a thoughtful check to make sure everything was okay and the new unit is compatible with my existing furnace.
I am very happy with their service.
Recently installed a tankless water-heater. Very satisfied and happy with the whole process converting from a water tank to this new system. Advisor Shawn, technician Hossein and his assistant were professional, reliable, skilled and able to provide excellent service.

Frequently Asked Questions (FAQ)

This depends on the nature of the problem. Most common AC repairs can be completed on-site in approximately 1-2 hours. Technicians carry common replacement parts to resolve issues in a single visit whenever possible. For major problems requiring special orders, we’ll complete temporary repairs the same day and schedule follow-up service as quickly as possible, so you won’t be left waiting long.

AC repair costs primarily depend on the severity of the problem and the cost of required replacement parts. Minor issues (such as sensors, capacitor replacements, etc.) may only cost a few hundred Canadian dollars to resolve, while repairs involving major components like compressors may cost over a thousand dollars. We provide clear quotes after on-site diagnosis and only begin repairs after receiving your approval, ensuring transparent and controllable costs.

We recommend proceeding with caution. AC systems involve high-voltage electricity and refrigerants, which are specialized areas. Non-professionals attempting DIY repairs may face safety risks and potentially cause greater damage. You can check basic items like power connections and whether air filters are clean, but deeper repairs should be left to licensed technicians for safety. When facing complex problems, contacting professional AC repair services promptly is the wise choice.
