Had a great experience with Delta from our initial sales meeting with Tanya, who blew us away with her knowledge and helped us make the right choice for our home, to a great install with Eric and Stephen. Would definitely recommend to anyone.

Delta Air just installed my new furnace, and they did a great job! The installers, Kyle and Cole, were very friendly and professional, and got it done in less time they expected to. They were quiet and didn't leave a mess afterwards. I am completely satisfied with Delta for taking care of my furnace over the years. Great company!

Braedon came over to help with our heat. Most HVAC people are nice but Braedon was super nice. He was informative and fixed our issue super easy. If you ever call Delta and get Braedon, you're in for some great service

Liam B and Fabio installed our furnace at the church. I cannot say enough about what an excellent job they did. They arrived on time, and were finished before their estimated time of completion. They answered every question we had in a friendly manor; and when they left, the area they worked in was cleaner then when they had arrived. If someone were to ask me if there were there any problems, I would say, without hesitation, that there was not. I would highly recommend them.

Called another service provider of gas fireplaces who directed us to Delta Air Systems as the only company locally that could service our make of fireplace. Breadon from Delta arrived as scheduled and quickly, competently and courteously had our problem solved and our fireplace cleaned and working like new. And all at a reasonable cost. Very impressed!

We recently had a humidifier installed in our new condo by Liam B, and Fabio. What a great experience! They arrived on time and completed the job professionally. They eagerly explained the function and answered all our questions, Liam went above and beyond by answering questions we had about our other heating and cooling components and their controls. We will continue to use Delta Air Systems because of their quality techs and friendly service advisors, Courtney and Annie.

Thank you Braedon!! Our furnace quit this past weekend: between talking with their emergency technician on the phone and then having Braedon come out for an inspection during regular business hours, everything has been quick, superior, professional, and transparent. Delta’s top-notch service and expertise gave us confidence and peace of mind— priceless!

I have needed a few HVAC systems over the last 10 years across different houses and Delta has always come through with a competitive price and the best customer service (no exaggeration, best customer service). I was returning from a trip and went to turn up the heat in my house remotely and found that the heater had not been working. I called Delta and they were able to get a tech out same day. Turned out it was best to replace the unit. They were able to get an estimator out that night and have me scheduled in for a new furnace the following day. Incredible. Kyle and Richard were the installers and did a great job. We have heat again just in time for the colder weather.I recommend Delta to all my family and friends over the years who have needed HVAC help and they have all said the same thing about the great customer service. It's what sets them apart.

Tanya was informative, knowledgeable and honest. Our in-laws use Delta as well for inspections and a new installation. Would use again. Middle range price point, imo, because we also got higher and lower quotes.

Excellent service, start to finish. We had some codes come up on our thermostat and our furnace was not heating properly. Based on positive reviews, I contacted Delta Air Systems for diagnosis. The technician, Tyler, arrived that same day and spent time assessing the unit and explaining the process as I watched.The furnace was 18 years old and required substantial repair. I was provided an estimate for repair and also the option of replacing the unit. We opted to replace.Our salesperson, Tanya, arrived that same evening and discussed our needs. No up selling and no pushiness. We received quotes the very next morning ranging from value, good, better and best. Tanya explained the process in detail and we had a clear understanding of what option best met our needs Tanya was there to answer all of our questions along the way and ensure our needs were met.We made our selection, and the installation team of Kyle and Richard arrived the next day. Kyle and Richard were friendly and highly competent. They laid down a runner to protect our floors and got straight to work removing the old unit and installing the new furnace. Our requirements were to have a new thermostat installed which would work with the existing humidifier, furnace and AC. The team ran into some snags getting the humidifier thermostat control set up but handled it like true pros and got it all working beautifully. They took the time to address any questions and Kyle showed me the work that was done on the installation. Kyle went above and beyond with the workmanship on the job, ensuring extra drains were in place to divert any condensation and to increase the service life of the unit as well as cleaning up some sloppy adjacent work from the previous installation. Once everything was explained, Kyle and Richard cleaned up and left the place spotless. I highly recommend Delta for HVAC needs and will be using them from here on out as well as recommending to friends and family. An excellent family run local business who does not sub-contract their work and operating with honesty and integrity. A rarity these days.

New to Kitchener area and my first experience with Delta Air. Cannot say enough about the entire team that helped me out. Huge compliments go out to Megan the technician, Tanya who provided the quote, and of course huge thank you to Liam B and Fabio. This team provided professional service along with great helpful information in a very friendly and timely manner. Liam and Fabio did an amazing job with the install and took great care of my home as they wielded large furnace pieces through my small home. I would highly recommend Delta Air Systems to anyone for sure. Thank you everyone for making this such a great experience.

Just had a new furnace installed by Steve & Cole. The initial quote was fair, all-inclusive, and without any upselling or unexpected additions. The install itself was clean and professional, and they were happy to answer any questions I had along the way, even those not directly related to the install. No regrets, and will happily call Delta first should I need anything in the future.

We just had Kyle and Richard here to install an air exchanger. Very polite and helpful when we asked questions. They explained the unit when they were done; how it worked and a few things to change if we needed to. Based on three work I certainly would not hesitate to recommend either of them to do work in any home.

I recently had to replace the furnace in my home and decided to go with Delta for the job. The experience has been excellent.The initial consultation with Matt was pleasant and thorough. I received several options with competitive quotes and was able to pick the one that best suited my needs and budget. Tammy coordinated the installation quickly. The installation process itself was fantastic. The crew, Kyle and Richard, showed up right on time and were able to finish up everything in about 5 hours: old furnace was taken out, new furnace put in, and the work area was cleaned up. They were very professional and courteous all throughout.I would highly recommend Delta to anyone.

Liam B and Fabio from Delta Air Systems were a dynamic duo! Work was done in a timely fashion and both were professional and took the time to explain how our new furnace and thermostat worked. Jason also helped troubleshoot an old existing duct problem and efficiently worked his way through our home until he found the problem. We highly recommend Delta Air Systems for the quality of their work/competitive pricing/and communication. A+

I had Tyler here last week to provide a maintenance check on our Carrier boiler furnace and attend to a problem with our direct vent fireplace. Tyler was extremely helpful and explained in detail every aspect of his visit, providing technical information as he diagnosed the fireplace problem. A co-op student accompanied Tyler on the visit and it was duly noted that he was treated with respect and provided with useful insights and helpful hints while he worked along with Tyler. I will be calling Delta from here on in, and asking for Tyler by name. Very impressed by this service call.

She was open to answer any questions on the matter even on weekend days.The installation crew (Liam B. and Fabio) did an excellent job of removing the old furnace and AC and installing the new units. They were professional, friendly, and knowledgeable, providing information about the work done and helpful tips on taking care of the installed equipment.Finally, Tammy registered the equipment with the manufacturer and sent the invoice allowing a convenient option to pay in two installments.We highly recommend Delta Air Systems to our friends, neighbors, and others.Yury & Alena

While exploring vendors for gas fireplace services it was clear that Delta Air Systems were up front and honest by displaying a price and stated the services provided for that price. This carried all the way through to the Service Dept that confirmed same. From the person who answer the phone/ service adviser/ to service person there seemed to be an excellent customer service culture in this company. Braedon the tech who came out, listened to what i told him about currentStatus of fireplace and went about his work efficiently. I was called into room for the Final adjustments on flame, testing of remote and general cleanliness to insure satisfaction.I would highly recommend Delta Air System - Great Job Braedon Thanks

Benefits of a Ductless Mini-Split System

Installing a ductless mini-split in your home comes with its own unique set of advantages. Homeowners who choose to either switch to ductless mini-splits or use them as supplemental cooling do so because they provide several benefits including:

Easy and minimally invasive installation
Energy efficiency and monthly savings
Improved air quality
Better comfort control with individualized room temperature
Reduced carbon footprint

How a Ductless Mini-Split Air Conditioner Works

What differentiates a ductless mini-split from a central air conditioner begins with how the system operates altogether. While a central air conditioner works to create cool air to disperse throughout your home, a ductless system simply removes the heat from the room.

A ductless system consists of two units: an outdoor unit and an indoor unit. The indoor unit uses refrigerant coils to absorb the heat from the air in your home, while the outdoor unit disperses the absorbed heat into the air outside.

Ductless Vs. Central Air Conditioner: Which is Best for Your Home

When it comes to choosing the right air conditioning system for your home, it isn’t a question of whether a ductless mini-split or a central air conditioner is objectively better across the board. Both come with their own unique set of advantages, and it’s about finding which features better fit your home and your lifestyle.

If your home has pre existing ductwork that can be easily fitted with a new central air conditioner, that’s most likely the right choice for you. However, if you have a very old or a very new home that doesn’t have proper ductwork installed, or if you need supplemental cooling, a ductless mini-split may be the way to go.
