Extremely professional, fast and was able to fit us into his schedule quickly.
We had purchased a house, that seemed to have everything in working order, until we moved in and realized that we had issues with hot water and other plumbing problems. Laith scheduled us in for a little later that week, came over to assess everything, showed us evidence that the furnace on the water heater was degraded and hadn't been serviced in many years, and then he gave us options in different price points to replace the unit. Once we chose what we wanted (Navien tankless), he came back with the new unit and installed it very quickly (considering that he needed to fix some venting issues that weren't up to code [which will allow us to make warranty claims, if necessary, in the future]).
There were a few corners that were cut on our house, and Laith was able to identify a few issues (even outside of his professional area, which he was 100% right about) and options for solutions. I'm very grateful that we reached out to HVAC Canada Limited, and couldn't be happier with the product, service, and high attention to detail.
