Alec and Brian called before the appointment and arrived at the communicated time. They quickly diagnosed the issue and provided multiple options to solve the issue. They treated our home and time with respect. I highly recommend Tellez heating and air.

We've had them service our air-conditioning for a few years now and they are great. The gentleman is knowledgeable in his field of work and he's always polite. I highly recommend this company!

I was very happy with Alec. My whole system went out while I was overseas. Alec was able to help me understand what had happened and gave me options to rectify the situation. He was able to get in the following day and begin work on my system, all while communicating via phone and email in a much different time zone. I was very pleased with the work and the outcome.

Tellez Heat & Air is a family owned business and their work ethic and professionalism shines through. Alec came in to our store, worked on our unit and found a part needed to be ordered. Also, he and his team discovered an issue in the air ducting which was affecting the cooling. Great find Tellez Team!! Part installed, ducting fixed, and cool air!! Highly recommend!

Incredibly thankful for Tellez Heat and Air. Alec is beyond thorough in regards to trouble shooting. He explains the problems and solutions available in a way that’s comprehensible. Very pleased with the new AC unit and would definitely recommend.

I was sent their information by a trusted source, and was very grateful for it! They responded quickly to my request, even though I know this is a busy season for HVAC service. And even knowing that I had an urgent issue, they charged me a very fair rate and provided exceptional customer service. I will definitely be using Tellez in the future!

He was very professional and very knowledgeable. He was able to fix my A/C problem all within a single day. 10/10 will definitely hire again.

Alec was our tech, and he provided great service! He got our AC up and running super fast and was a pleasure to work with. I definitely recommend him to anyone who needs reliable, professional HVAC service!

I had a great experience with Tellez Heating and Air and recommend them highly. Julio and Alec were incredibly professional, honest, efficient, and transparent throughout the entire process. I primarily worked alot with Alec and he was very communicative. He gave me a range of options and gave me the pros and cons for each. took the time to explain what was going on with my HVAC system. As a first time home buyer I had alot of concerns. Alec took the time to answer all of my questions (probably a few dumb ones too) but was happy to answer. I had already got a few quotes, but when working either Tellez there were no sales tactics or pressure to make a quick decision which made me feel comfortable going with them. My experience with them was great and ultimately I’m incredibly happy I went with them.

I had a great experience with Tellez Heating and Air. Alec was incredibly knowledgeable, arrived on time, and quickly took care of our air conditioner's service and a condenser replacement. He took the time to explain what was going on and how he fixed it, which I really appreciated. He also provided before and after pictures. Excellent, professional customer service from start to finish. five stars!

Alec was very thorough in trying to troubleshoot the issue I've been having with my AC. He was very friendly and efficient. I'm very happy with his honesty and genuine concern to get the problem solved without trying to sell me anything I didn't need. Thank you Tellez Heating and Air!

We recently had our furnace replaced by Alec and Julio. The team was professional, knowledgeable, and easy to work with from start to finish. We've used them over the years and been happy every time. The workmanship was outstanding, and they made sure everything was working properly before they left. They delivered trustworthy advice, quality work, and fair pricing. We’re very happy with the results and would gladly recommend them for heating and air services!
