Delta Air Systems

We had Delta out to service our furnace. We are so impressed with the company and their customer service. Braedon was our service tech and he did a wonderful job ensuring that our system was functioning properly.

Great professional service. Excellent installation and service from start to finish. The Lennox furnace is so quiet and heats the whole house. Would recommend delta air systems to everyone. Your whole team Jason, Matt, Brad, Julien and Tammy have been great to deal with.

We had Delta Air put in a furnace past winter -no heat - they came and fixed next day - i was impressed with their fast response and clean work i had them come install my garage heater - Matt and Brad were excellent - professional very clean and detail oriented - they even checked all the other Gas fittings while there to ensure no leaks or potential issues.
Special thanks to Both Kevin and Vince as well for making this happen for me.
Delta Air is my 1st choice and should be yours too for Clean install professional service and old school approach to all customer needs. Well done guys - thanks a bunch . Sandi

Recently had my furnace tuneup by another dealer in town. My furnace was red tagged with Kitchener Utilities for a defective heat exchanger. I got second opinion and inspection by Zach at Delta. His inspection showed the heat exchanger had no defects. We were quite impressed with the prompt response and professionalism provided by Delta.

I am very pleased with the Daiken Air Conditioner and Furnace installation.
Delta Staff are very friendly, professional and great to work with. We knew we made the right decision when we needed to call on Delta more than two years later. Their service was prompt and very courteous in a professional manner with a positive interest that customer needs come first.

Thanks Delta

I first hired Delta systems for a furnace replacement in 2015 when I competitively priced our a new system after the existing one cut out in middle of February. Not only were they the most competitively priced, the service they provided from sales to install to accounting was exceptional.

Since then, I have used them to install 2 other HVAC systems, a gas fireplace, and they do all my inspections and service work. They're quick to respond, always friendly, and the technicians are fantastic and work directly with my tenants to resolve issues.

Seldom do I come across a company that I can recommend to others by putting my own reputation on the line (I have recommended them to family, friends and co-workers).

My only hesitation in giving them a perfect review is that I wish I could keep them as my little secret.

Delta Air Systems is a professional, high quality company. All staff are friendly, courteous and knowledgeable.

The installers were clean, conscientious and very focused on doing the job right - the first time.

Scheduling was accurate and helpful.

I very highly recommend Delta Air Systems for all HVAC systems and needs.

i was extremely pleased with the work ethics of the installers had. They made me feel like my home was there first on their mind and job to be completed that day. Was very pleased with everything the service team did and would highly recommend them to family and friends to use .

Every person from Delta that we have spoken with has shown the knowledge required to diagnose and fix our issues without hesitation. This is what one might expect from any company, but, we all know that is not always the case. What sets Delta apart is their professionalism and willingness to go the extra mile to ensure our needs were met in a more than timely fashion, that no detail was left unchecked, all while displaying a genuinely happy and positive attitude. Calvin and his team have been the leading company in their field for so many years for too many reasons to count. Thank You for taking care of my family as you would your own.

I had a Lennox furnace/AC installation with Delta Systems a few months ago to replace our 22 year old unit, and just got around to leaving a review. The team was absolutely amazing; the best people I have ever dealt. First off, due to Covid, I wanted to limit in-person interaction as much as possible. As such, everything---from checking the configuration of my furnace room, to deciding which units to purchase---was handled/decided over email and video calls with Jordan. Jordan is extremely patient in answering all my questions; she's quick to respond to emails, clear in her explanations, flexible, personable, enthusiastic. The installation went smoothly and was finished within 1 day, and I mostly communicated with the installation team (Jason & Andrew) by phone. Tammy handled the payment and warranties. The whole process was so smooth and transparent, in part due to the excellent communication between the whole team (for example, Jordan passed on my instructions to the installation team, and everything is documented on their online system). The quotes are also reasonable; I have compared a few quotes from other companies before going with Delta. I was quite nervous about getting such a big job done while the pandemic is still going on, but the Delta team made my family and I feel extremely safe. It has been a few months now, and we haven't experienced any issues with the new heater/AC system; it is quiet and comfortable. Highly recommend Delta Air Systems to anyone who might need heater/AC installations.
