Kosel started their company due to friends and family wanting to get a fair shake and quality repair service at the same time in the Austin area. So, in June of 2001, Kosel AC & Heating Inc. was established. We immediately began to pickup business when word got out that Steve was now an independent contractor.

Word has spread so far in fact that we have had contracts stretching across Texas in Lubbock, Houston, Corpus, and Dallas. We are proud to say we specialize in not only heating and cooling but also refrigeration services. Commercial restaurant chains have been using our expertise since 2009! New Construction companies have loyally used us since 2005!.

Don't fret now! All those commercial services opportunities didn't come out of nowhere. Our residential business was all word of mouth from friends of our friends and family. We'd love to expand and share our fair pricing, reliability, and expertise with your family too!. Some of the areas we serve include Lubbock, Houston, Corpus, and Dallas.

Called on a Saturday afternoon because my heater stopped working. Someone actually answered the phone- I had called 4 other local businesses w/no answer or callback.
Finally posted on IG asking for a referral and got Kosel.
They had a technician at my house within an hour.
Gave me a fair quote and very professional. Will be referring to my friends if anyone needs! Thank you- no one likes to be cold at home. 👍🏼

Kosel diagnosed my HVAC which was not blowing cold air. Kosel’s tech came out, said I was low on coolant, and said the cost to recharge with Puron R410A would be $300-$400 (max). Kosel spent 25 minutes recharging the HVAC, and then the tech called his dad (who owns the company). After calling dad, my bill was $560… 40% higher than the original $400 estimate. They charged me $80 per pound for 7 lbs of Puron… the tech said he actually didn’t even know how much Puron he added (so he called dad for pricing). Wholesale Puron goes for less than $10 per pound (google it if you like). Even though

Great service. My heat pump was not switching to cool mode. Their technician called when he was on his way and arrived on time. He took his time diagnosing the problem as a faulty thermostats. He made it clear that there would be an additional charge to install a different thermostat before proceeding which I approved. I'll call Kosel AC & Heating for any future HVAC needs.

These guys are absolute lifesavers! We had our furnace break in the middle of the ice storm, they drove out and got us up and running when no other companies were working, and did it for a beyond reasonable price. Definitely recommend them for any HVAC needs.

Kosel said they would be here at 9 am and the technician was here promptly at 9am!!! He was thorough in his explanation and repair of our issue. And also provided (by email) a detailed summary of what services were completed. We will use them again without hesitation and will be telling our family and friends. The price could not be beat. Very impressed with them.

I cannot say enough about my entire experience! I relied on a company to come out, never showed, after they finally called me back they told me they could not come out until Monday and this was a Friday. So , needless to say I was frustrated, 2 older dogs, and my husband and I both work construction, there was no way I could imagine being in the heat for 3 days. I called the office at Kosel and treated me soooooo great ! I couldn't believe it. Heather was super kind and compassionate to our dilemma and checked on things and called me right back. Patrick was here within the hour. Let's talk price

My thermostat was completely blank. I changed the batteries and checked the breakers and nothing. They came out within 2 hours and found the oxidized wire! He temporarily fixed until I get the new thermostat. Super friendly, knowledgeable and honest!

Mark arrived on time and was very professional and quick with our repair. He also discussed options
that were offered by Kosel for preventative maintenance if we decided that was an option for us.
He discussed any future repairs that we might need. Kosel AC & Heating has always given us GREAT service - even came once on Mother's Day!! Thanks!

Worked with Lisa and Christi at their Cedar Park office. Both have a wealth of industry knowledge and help get customers the HVAC services they require. They are locally owned and operated so they understand the value of having great customer relationships. Highly recommend.

I have a dual zone system that needed to be rebalanced as well as replacing a coil. It is evidently a pretty complicated system as I had a couple of people not want to work on it. Mr. Kosel gave me a precise analysis of work to be done, completed it on time, and made 3 follow up visits to tweak the balancing to the renters preferences. I am very happy with the work that they did, and I feel as if it was a great value for the money.
