Dominic Lévesque –
Great dual-zone unit. The mechanical work was top-notch.
Gursharan Gill –
Professional from start to finish. Jimmy HVAC took the time to show us how the remotes operate, how to balance the two zones, and how to rinse the reusable filters.
Noreen Rideout –
The heat pump performs well in both heating and cooling modes, but Jimmy HVAC had to reschedule the initial appointment by two days. The installers were very skilled once here, though.
Wesley Froese –
Independent control for the bedroom and living room has completely ended the thermostat wars in our home. Excellent recommendation and fair pricing from Jimmy HVAC.
Stéphanie Galarneau –
The Zero Ductless Heat Pump maintains temperature in both rooms flawlessly. Docking one star because the crew left a roll of electrical tape and some plastic packaging behind in the spare bedroom.
