Delta-T Air Conditioning & Heating

Delta-T Air Conditioning & Heating operates out of San Antonio, Texas, and focuses on HVAC services for homes and businesses across the region. They handle residential air conditioning repair, heating installation, mini split systems, duct cleaning, and refrigerated air conversions along with commercial HVAC work. Their licensed technicians manage both new setups and ongoing maintenance to address the demands of local weather patterns that push cooling systems hard in summer and require reliable heating when temperatures drop. The company draws on years of hands-on experience to deliver solutions that keep indoor conditions steady without unnecessary complications.

Homeowners have described specific jobs handled by the crew. Lucas received a Mitsubishi mini split where Travis offered guidance on the right configuration and ways to reduce costs while Kevin and Carson completed the install quickly and cleanly. East Texas Cowboy had Travis and the team put in three high efficiency heat pumps plus a garage mini split and noted the savings on the units along with daily cleanup during the project. Cathleen Richardson contacted them after hours when her AC failed in peak summer heat and Travis arranged for Harvey to arrive the next morning to diagnose and repair the issue in detail. Susan Brownfield worked with the group on a job where Travis explained every step, arrived on time, answered calls promptly, and made sure the outcome met expectations.

Customers consistently highlight fast response even outside regular hours, solid quality in the finished work, straightforward pricing, and direct communication that keeps everyone informed. These patterns show up across accounts of urgent repairs and full installations alike, with technicians taking time to explain problems and leaving sites in good order. The approach builds trust through repeated attention to practical details rather than shortcuts. DIRT Score 4.78 from 36 reviews on Finds.

“I’m super happy with my new Mitsubishi mini split from Delta T! Travis was awesome — he gave me great advice on the best setup for my place and even found ways to save me money. Kevin and Carson handled the install, and their work was top-notch. They were fast, professional, and the installation looks incredibly clean. They had to work around a few tricky requirements, but they planned it out perfectly. The whole process was quick and easy from start to finish. Couldn’t be happier — highly recommend Delta T!”

“Travis and his crew recently installed three Mitsubishi high efficiency heat pumps on our home and a Mitsubishi mini split on the garage. Not only did he save us a lot of money on what are relatively expensive units, but his crew did a great job on the installation, cleaned up everything each day when finished, and were just great to work with. Travis made multiple trips out to help us decide on the right equipment and went the extra mile in making sure we were happy with the job when completed. If you're looking for fair prices and good quality work you'll be very happy with Delta T. And if you're looking for the best quality HVAC brand out there, you should take a look at Mitsubishi. They are the Rolls Royce of AC units.”

“Heat of the summer and I came home to my AC not working! Not only did Travis respond to my message after 9pm when I contacted him but had a repairman at my home the very next morning BEFORE the time I was given! Harvey was professional, courteous and very detailed in explaining the problem and fixed it promptly! The pricing is very reasonable and the work is nothing but quality! Thank you again gentlemen for getting the AC fixed in my home for my family! Will be using and recommending you from this point forward!”

“Awesome job and great team! Professional, honest, thorough, and makes it a point to make sure the customer is happy. Travis made it a point to make sure he explained everything, showed up on time, answered all my calls promptly, and went above and beyond to ensure we got what we needed within the budget we could afford. He has my families business from now on and I will make sure to refer him to everyone I know.”

“We are a repeat customer primarily due to Delta T’s attention to detail, getting it right the first time, and quality service - all at a good price. I highly recommend Travis and his crew for your next HVAC project. We live in Houston and his crew travelled to complete the install for us. Awesome work guys!!”
