We were looking to have our furnace and HRV system checked out for a regular maintenance and Will came to the rescue! He was very professional and was able to get out to see us that same week. While doing the maintenance he found some issues with our HRV that was quickly fixed, and that the heat exchanger to our furnace was clogged. He quickly went to work looking into the warranty coverage for us and was able to order the part, and have it installed a week and a half later. Incredibly quick, friendly and thorough service, at a very reasonable price. Highly recommend Enns Air!

Will came recommended by a neighbour. Prior to the start of work Will was responsive to assure we had the correct sized system and rebate qualifying models selected. Not a one size fits all approach. Will and McLean showed up as promised, provided excellent advise on internal unit placement, we're efficient and clean in their work. PROFESSIONAL work all the way. Would recommend Enns Air any time.

Will and his team are incredible. They are very responsive - even during busy periods Will will make sure he responds. He truly cares about what he does and how he can help you. Will provided me with multiple options and tried to solve our problems using the cheapest and most efficient ways first. He wants you to be happy and wants your heating and cooling to work. He made some great suggestions and did exactly what he said he was going to do for a reasonable price.

The first time I met Will and Maclane, was when they repaired my gas fireplace. Both were friendly, knowledgeable & efficient. When I needed a new thermostat, I decided to call ENNS AIR again. Will was very helpful to recommend a few different models. And then Maclane came out to install it effortlessly. I just recently had a new Central Air A/C unit called "AIREASE" installed efficiently by Will and Maclane. It has a great warranty plan for labor and parts. I found each time, it was great customer service. I would highly recommend ENNIS AIR for all of your heating and cooling needs. Thank You for your help, Shelley Vaughan
