    Responsive and punctual, GForce took the time to understand what we needed and provided a quote quickly. Greg worked with us on tweaking the proposal and kept us informed right up until install day. The heat pump install was as quoted and promised, and the crew cleaned up after themselves. We’re very pleased with the work and the end result.

    We just had GFORCE Mechanical install a new heat pump. Greg was professional, everything was as quoted and he and his assistant did a phenomenal job. We highly recommend this company!

    Great professional service. All the work was done as stated at the quoted price, no hidden surprises. We were referred to this company by a neighbour and we’re so glad we listened to them. They cleaned up after installing the heat pump and left the place cleaner than they found it. The outside install is very neat in appearance and doesn’t have wires or hoses sticking out like other “industry leaders” in the heat pump industry. The owner Greg does the installs along with a coworker. I recommend this company highly!!! Raj
