Great service - I was very pleased with everyone involved in the attempted repair of my old furnace(Tyler), sale of new one (Jason) and installation of the new unit (Julian and Ben). All were prompt and very respectful - even bringing a heater to help us keep warm. All in all, a really good experience.

I had a great experience with Delta Air, I inquired about a humidifier for my furnace. The sales team reached out to me and provided valuable information. The tech who installed it was super nice and the job is very well done.

Its stressful when your furnace stops working in mid-December. And when the company you normally deal with tells you the parts needed are on back order until nobody knows when, and they have no one available to install a new one until sometime next year, well
My next call was to Delta Air Systems. I knew nothing about this company at the time but almost instantly realized Id come to the right place. Yes, we can install a new furnace tomorrow or the day after, Tanya assured me, if needed. Ill be there to take a look in the next hour or two. She did her best to see if repairs

We bought a Daikin ductless a/c and heat pump from Delta and the customer service was second to none. Tanya at Delta listened to our needs without trying to upsell us extra units. Our unit was on back order for a while but Tammy kept us in the loop and booked us an installation date quickly after the unit was available. Liam and Matt were our install team and they did a great job - very professional and pleasant guys, they installed the unit with far less disruption than we thought would happen.
Overall, we are extremely happy with our experience with Delta, and would highly recommend them for

After 24 years, our furnace had a violation which required immediate attention. Jason attended our home and explained what we needed based on the size of our home. His suggestions were reasonable and he explained the differences between products very well. We were impressed by his matter of fact approach. The head technician who attended the install was Steve and we were impressed by their attention to details. They layed rugs to walk on and wore booties and when they finished they left everything clean. We would highly recommend Jason and Steve as the go-to team!
