We were very happy to have Scott visit again today. He completed our regular inspection. He also dealt with a small repair after having explained all the options and costs upfront. It's so nice to deal with someone who is consistently punctual, polite and knows his stuff. We've recommended Scott and Francis Home Environment Service Experts many times in the last 6+ years. From sales (furnace & a/c) through installation and service, we've always been happy.

We had AirZone install a new AC unit to replace our old one. Not only did they quote the best price, the customer service was outstanding. Their techs were friendly and professional, and did a great job on the installation. We even got a follow-up to make sure we were satisfied. I would highly recommend AirZone if you're looking for a good HVAC company in the Ottawa area.

Great service. Initial installation of furnace and air conditioner excellent job - friendly, knowledgeable and hard working. The technicians performed customization work to connect the new furnace with the old duct work, as well as the updated electrical requirements for the AC, without additional cost. They also walked me through the various exhaust options that were available and recommended the best one for my needs. Highly recommend.
