MEET OUR FOUNDER, NATHAN REEVES
Our founder, Nathan Reeves, got his start in HVAC 15 years ago in Dallas. He worked his way from maintenance to repairs and installations, and eventually managed a full-service team. But after years in large franchise companies, he saw a better way to treat customers. He built Koala-T Heating and Air to focus on doing right by you, with fair pricing and technicians who genuinely care about the work in your home.
When you call us, you’ll have peace of mind knowing that you're dealing with a family-owned local business, not a corporate chain. Nathan is involved in every job we do, so you always know who you’re trusting with your home.

AC AND HVAC INSTALLATION OR REPLACEMENT
If your HVAC system keeps breaking down or your energy bills are climbing, it might be time for a replacement. We provide free estimates for HVAC installation and will take the time to explain every option, so you can choose the right system for your home and budget. We'll handle everything from start to finish, making sure your new system runs efficiently and keeps your home comfortable year-round. Every installation includes up to a ten-year warranty.

AC TUNE-UP AND MAINTENANCE

Our certified technicians offer maintenance-focused AC services that involve checking the key components of your system, cleaning what needs cleaning, and making sure everything works the way it should before the summer heat arrives. We offer a spring AC tune-up for $89, extending your system's lifespan and helping you enjoy healthier air at home.

FURNACE AND HEAT PUMP SERVICES
When temperatures drop in North Texas, you need to know you've got a reliable heating system ready to warm your home. We repair and install gas furnaces and electric heat pumps, helping you stay warm no matter how the weather changes. If you’re not sure what system suits your home, we can design a dual-fuel setup for a good balance of efficiency and performance, with our installations and repairs backed by a five-year parts and labor warranty.
WHOLE-HOME INDOOR AIR QUALITY
If your home feels dusty or your allergies keep flaring up, we can recommend and install tailored solutions to improve your indoor air quality. We start with an assessment to measure things like particles, humidity, and airflow, then recommend what your home needs. That could include filtration systems, UV lights, duct cleaning, or a whole-home air purifier. We'll install everything properly, and all IAQ products come with a lifetime parts warranty.
COMMERCIAL HVAC
Your business can’t afford downtime from heating or cooling issues, and our commercial services are designed to keep your HVAC systems running smoothly. We work with offices, retail units, restaurants, and light-commercial spaces, offering everything from rooftop unit repairs to full system replacements and maintenance plans that fit around your hours.

I had a maintenance service done by Koala-T Heating and Air, and I was very impressed. Nathan Reeves, the owner, handled the call himself and was professional, punctual, and extremely knowledgeable. He took the time to explain everything and made sure my system was running perfectly before he left. It’s clear he takes pride in his work and truly cares about his customers. I highly recommend Koala-T Heating and Air for honest, reliable HVAC service.
JOHN WILLIAMS
I had the pleasure of meeting Nathan several years ago, great Man and his beliefs are even better. This man is the epitome of what you expect from a top notch company. Nathan has serviced my system for nearly 8 years and I’ve followed him back when he was working for other companies. Full circle he has made his own company and we couldn’t be happier with his service. He’s prompt, respectful and offers a TON of value. We unfortunately ran into a compressor failure on our 19 year old system and decided it was best to upgrade our central HVAC system. Nathan’s crew was a mirroring image of everything he stands for. The install was clean, efficient and best of all affordable compared to your big box companies. Thanks to Nathan he has made us believers for life. Thank you so much for everything you do!!
