After 20 years our furnace needed major repairs, and because of the government rebate offer we decided to install a new Lennox furnace and a Mitsubishi heatpump system. The latter arrived a couple of weeks after the new furnace had been installed, but one day after final delivery the Walchuk crew promptly finished the job. It took the better part of the whole day, since we in addition got rid of our old boiler and changed to a Navien tankless water heater. The crew didn't leave until everything was running smoothly; we had hot water and a cozy, warm home again without major interruptions. We're looking forward to your maintenance efforts we signed up for to look after our efficient new system. Awaiting our rebate from ON government.
