• Jason and his team did a great job and installed a great system. The only regret I have is not calling them at the start of the summer! From estimate to project close out, the Delta T team was very response, honest, and hard working.

  Michael M.★★★★★

• Delta T is fantastic. They put in a brand new air conditioner unit and was significantly lower in price than others that I checked with. They are also very quick to respond and so reliable. Will only use their services moving forward. Highly recommend!

  Tammy Y.★★★★★

• Awesome company. Did an amazing service job for our home for swamp cooler maintenance. Very thorough. Thank you.

  Rhea M.★★★★★

• I've been with Delta T Heating and Air for many, many years. My parents before used Delta T Heating and Air and air. way before me. This is one company that will not screw you over. They're very honest and tell you the truth. And not try to sell or oversale anything that you do not need done. And family owned.

• 10/10! Jason came out for a second opinion after our big hvac company said we had a cracked heat exchanger and needed a new furnace. He was extremely diligent and concluded that our furnace was working fine after using a scope camera with me right by his side. He was kind, honest, and explained everything clearly to me. Didnt charge me a dime either! I will be saying goodbye to our previous hvac company and will be using Jason and Delta T for all of my hvac needs!

  Kenton M.★★★★★

• Jason was phenomenal, so quick, so honest, and so kind. Will be coming here in the future for all my HVAC needs!

• I can't say enough about my experience with the Delta T family. I called them for a second opinion about my furnace needing replaced. Jason Sr. came out and took the time to walk me through each test and the results (which my other provider didn't even test) to show me why it needed replaced. Then, I had both companies propose and the personal touch combined with competitive pricing made my decision to choose Delta T easy. I had my furnace replaced in just a couple days. Jason Jr. and Justin were so diligent and personable. They also took time to answer questions and even improved on the position of the furnace and the connections from the builders original install. Replacing a furnace you thought was working is REALLY unsatisfying, but the team at Delta T made it a great experience that I feel good about. They will be my first call in the future.

  Shannon M.★★★★★

• Very knowledgeable, helpful, and kind. Appreciate the honesty. Would absolutely recommend. We like supporting local small businesses too.

  Kim M.★★★★★

• Justin & Jason were hired as a subcontractor to install a new bathroom fan for a remodel project at my house. They were very friendly and did great work. When a different subcontractor hired for my project, went in and messed up Delta T's work, they were willing to come back and fix it. Justin went above and beyond to clean up the other subs' mess and make things right in my home. I really appreciated his dedication to making sure that everything was installed correctly and looked good.

  Claire R.★★★★★

• I am so glad I called Delta T Heating & Air for a 2nd look at our AC unit! I had another company out this morning and the technician that arrived could not figure out what was wrong and admitted he was not very knowledgeable about the issue. I then called Delta T Heating and was able to get someone out within a few hours of my call. Jason with Delta T Heating was knowledgeable and professional and even gave me an AC unit 101 lesson. Will definitely call them for my future needs!

  Nancy D.★★★★★

• The reasons I went with Delta were price and speed. I wanted to get central AC installed in the middle of summer, and other HVAC companies I talked to were booked out for weeks. Delta came out the very next day for a quote, and had the proposal ready in under 24 hours. When I called them on Friday to schedule the install, they were at my house the following Tuesday. The install took only a day to complete, despite complications with my existing ductwork. The crew was very professional, they answered any questions I had as a first-time homeowner, and they cleaned up afterwards. All at a price that was 25% lower than the next best bid!

  Nathan D.★★★★★

• Delta T is the way to go! This review is long overdue (my apologies.) In the hottest part of last summer, I had an A/C emergency and Delta T was quick to respond, within a 2-3 hours. They quickly identified the capacitor had gone out and thankfully had one for my unit on hand. Within minutes, my A/C was up and running again. My unit is an older one (but still works good) and instead of trying upsell me (like I'm sure the big name companies would,) they fixed the problem, saving thousands on buying a new unit. Repairs will always be expensive on big appliances, but I'd rather spend a few hundred than several thousand. Friendly, prompt, polite, professional and fair. It's refreshing to know that there's a trustworthy company, like Delta T, that you can rely on to not take advantage when you're in need of service. If and when I have another HVAC need, I will be reaching out to Delta T. Thanks Delta T!

• ⭐⭐⭐⭐⭐ I had a fantastic experience with Jason from Delta T Heating and Air! Scheduling was easy, and he arrived right on time. Jason was incredibly nice, answered all of my questions, and took the time to explain how my heating and air conditioning system works. He was fast, efficient, and made the whole process smooth and stress-free. I highly recommend Delta T Heating and Air for their excellent service!

  Elizabeth A.★★★★★

• I've been very happy with them, then just installed a new furnace at a reasonable price (I compared), they did A/C for me a number of years ago as well.

  Caroline H.★★★★★

• Very professional and educational. From the call with Jamie to the service repair rendered by Joe, these guys are top notch and highly recommend them for all HVAC needs!!

  Brandon T.★★★★★

• I have been a customer of Delta T for close to 25 years and I cannot say enough about Jason, the owner, Justin and Jason. They are a terrific team - honest, diligent workers who provide reasonable pricing, great work and share all their knowledge as to what they need to do and how they plan to approach the job. They have replaced two air conditioners as well as a furnace and hot water heater for me over the years. They are the only firm I will ever use for my repairs. I highly recommend them!

  Rita G.★★★★★

• Last summer thieves ruined my outside air compressor when they attempted to steal the copper tubing. I received 4 estimates, including one from Xcel Energy. Delta T saved me thousands of dollars and gave me a much more efficient model than the other contractors. Everyone at Delta T was friendly and very knowledgeable. Jason did NOT try to sell me a more expensive model or additional equipment. Instead he talked me out of changing some of my ducts to improve cooling in the summer. After installation, I had a minor problem with the thermostat. When I called I talked to a real person and they were out that day to fix it. Jason also gave me excellent advice about leaving my furnace blower fan on which has made my home more comfortable, especially in summer. I can't say enough about how great it is to deal with an honest, trustworthy, local, family business!!!

  Ronald T.★★★★★

• Family owned, honest, knowledgeable, hard working, and fair. Our furnace died a few days ago. We called a highly rated company and they recommended we replace both our furnace and ac. We knew we’d have to at least replace the furnace and likely the ac at the same time because we have a downflow system and decided to get a second opinion because the price was steep. Jason came over and agreed with the diagnosis, but quoted us a price for a comparable system that was about 33% cheaper. When we’re talking about tens of thousands of dollars, that’s a lot of savings. They worked hard the next day to get our heat up and running. They even found a problem with how the old system was wired and fixed it with our new system. They were professional and friendly the entire way through. I couldn’t recommend Delta T enough!

  Mark F.★★★★★

• Excellent service and detail.

  Rob W.★★★★★

• We came back recently from a trip with our furnace out during a snowstorm. Having 2 babies, we couldn’t wait days to get heat. Most places we called could not get us in for 2-3 days at least. Jason went above and beyond to come same day to repair our furnace. His prices are honest, he is extremely knowledgeable, and a great guy to work with. We highly recommend working with him and plan on doing so in the future!

  Parker L.★★★★★

• We had a problem with our air conditioner and Delta T came out the next day and fixed it. Jason was very knowledgeable, professional and has a very nice personality. I would highly recommend them.

  Leslie P.★★★★★

• I wanted to share a very positive experience with the team at Delta T. They were able to find time for an appointment on a 90+ degree day. Came out promptly, and were very professional and courteous while at the house. I also feel like the overall value was better than other HVAC companies I had tried in the past. Will be sticking with them going forward!

  joshua C.★★★★★

• Delta T replaced my air conditioning unit today. Delta T was very responsive and prompt. Justin was thorough, polite and very knowledgeable. Happy to recommend them. Thank you Delta T

  LJ B.★★★★★

• We have used Delta T since 2010, always very happy with their service! Jason, Vicki, and team are great. I trust Jason, he takes really good care of us!

  Elizabeth F.★★★★★

• Jason and Justin are great! So professional, responsive, and thorough. They took care of our water heater emergency and we were so thankful. The team was communicative and cleaned up so tidy when all said and done. We had used them 4 years ago for a new furnace and A/C unit install and so happy that we called them again for our water heater. Will definitely recommend!

  Coby C.★★★★★

• Justin and Jason did an absolutely fantastic job at installing our new heat pump, furnace and thermostat a few weeks ago. They took great effort into making sure our floors were protected while moving in and out of our home, which we really appreciated. After removing the old thermostat they even went above and beyond by painting the small area on the wall before installing the new thermostat so it looked seamless. They were very thorough, very polite, and very professional. I’d use them again in a heart beat and would definitely recommend them to anyone needing such services. Thanks for your hard work guys!!

  Dominic E.★★★★★

• They installed an Aprilaire Filtration and humidification system and Global Plasma Solutions (GPS) Needlepoint Bipolar Ionization (NPBI) Air & Surface Purification System. The team was great. Very professional. Called before they came. Cleaned up. Explained the installation after they were finished. Helped install online apps to use. They went above and beyond to assist with questions we had. I would highly recommend them for my next job or my neighbor's job. I did a lot of research and I'm so glad I went with this company. Two brothers came and it took them 4+ hours for the installation. We look forward to using the products to have cleaner air in our home. Thank you Delta T Heating.

  Jodi D.★★★★★

• Great company! I would highly recommend. We got an estimate for work we needed right away. Pricing was great.They installed new heater and water heater the very next day. Very professional and efficient service.

  Doug H.★★★★★

• I have been using them for years and they always get the job done! I wouldn't recommend anyone else.
