How To Maintain Your AC Unit During The Off-Season

Mike and his apprentice always do excellent work. Prompt, efficient, honest and dependable. I recommend without qualification!

I own several rental homes throughout Johnson County and exclusively use Delta T to service and install at all my properties and my personal residence. Have referred them to several friends, family and coworkers without hesitation. Professional, efficient and always come through with high quality work at an affordable price.

We were very pleased with Adam and the crew. We found them knowledgeable, professional and competitive in price and we’re happy to recommend them.

Good experience with Delta T Heating & Cooling. Service Tech Garrett was on time, professional, and personable.

After getting several estimates and talking with 3 other companies, it was clear Delta T was the right company to replace our aging furnace and AC unit. They offered a very competitive price but what really impressed me was Adam’s knowledge, attention to detail and desire to make sure the installation was perfect. I highly recommend these guys, you won’t be disappointed.

They were great! Garrett the technician was very nice and thorough. I was able to make an appointment quickly, and their prices were reasonable!

I was so impressed With Delta T Heating & Cooling. They were a phenomenal company to work with and I will continue to use them! Thank you so much to Adam for taking care of our AC!

Great service. They gave me 3 options for my house. Explained the differences and installed a great system. They did great work at a great price. Love the new HVAC.

Greatest crew! Very knowledgeable, and were QUICK to get my issue resolved-Thank you Adam, for getting me scheduled so quick-and thank you Mike & Garrett for your expertise and quick resolve

Delta T is my “go-to” HVAC service company. Always very prompt and extremely reasonable on price. You will be glad you called Delta T.

Every interaction with Delta T has been very positive and helpful! Mike went goes and beyond to help explain things & the maintenance plan has been very beneficial for us! Highly recommend!

Delta T has provided service for my HVAC system and water heaters at multiple properties for the last 4 years. Quick service, good communication, fair prices. I trust them implicitly.

The tech came and checked our heating system, got it all ready for winter, and explained everything I needed to know, for a reasonable price. Bonus, he also explained 2 or 3 ways why upgrades wouldn’t be necessary, and how to prolong the life of the system. Will definitely continue to use them.

They fit me in their schedule pretty late at night. Theres a storm coming and they were understanding and fixed my issue quickly. I purchased their program to have them come out annually now. Thank you guys!

Mike Jeanneret was our repairman and he thoroughly explained everything he was doing and why he was doing it. He didn’t charge us for anything we didn’t need and I feel confident that he was honest with his work. Would recommend to anyone!

I’ve used Delta for several years both at both my personal residence and my work building. They have always responded quickly and efficiently. I’ve been so happy with their service and never trust anyone else

Mike is absolutely the best! Honest, kind and very professional. I've dealt with a few other companies before going with Delta T....it was like night and day! So refreshing to deal with an honest and affordable company. Thank you so much!!!

Punctual, courteous, prompt & reliable service - the perfect recipe for great service! Highly recommend to others!

Mike Jeanneret was/is absolutely fantastic He spent as much time as necessary, and then a bit more to explain everything that he did and all the ins and outs of our system. We use DeltaT for yearly maintenance, and could not be happier. Highly recommend Mike and DeltaT

Efficient, knowledgeable, reasonably priced. Garrett and Daniel were very helpful and were fantastic at explaining things to me. Highly recommend.
