  • 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.

    Tellez Heating and Air came out at 6:00 on a Friday evening to fix our air. In 104 degree heat, we were panicked as the other two companies we called couldn't get out until Monday. Despite the late call, Alec was thorough, patient and determined to get us back up and running at a fair price. I will definitely use them again and hope you give them a try as well.

    They came out the day after I called needing help with my AC system, which was great! They looked at everything, diagnosed the issues (more than one), and got the systems running effectively. Really well done.

  • Hello. My air of course stopped working when it was 104 degrees out. Not only was my landlord very quick at fixing but when he couldn't find out the issue, he then called Tellez heating and air. A very nice and professional young man named Alec called me within 15 minutes and showed up within the hour. He was so quick and found out the issue and had my home cooling down in no time. I also have large dogs and they both absolutely loved Alec. Which doesn't happen!! If you need anything done and need a heating and air guy I highly recommend Alec. Thanks again for cooling us down.

    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!

    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.

  • 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!

  • I pride myself at finding the local small businesses, specialists who become no-brainer back pocket go-tos for life's needed fixes. I'm very happy to add Tellez Heating and Air to that list. Alec was as courteous, patient, and efficient as could be. He helped us diagnose the issue with our AC and get it up and running quickly and at an incredibly reasonable price. When friends ask about HVAC fixes in Tulsa anymore, I will just say "Safe yourself the hassle of looking around -- just call Tellez." No brainer!

Frequently Asked Questions

1. How often do I need to change the filters?
The rule of thumb is to change your HVAC filters every other month, but ultimately, it depends on how much your filter needs to work. Keeping your house clean requires less work from your filter to make the air cleaner.
2. What size unit should I use?

While there is a lot of info that goes into this, it is recommended to have about 1 ton per 400 square feet. However, other factors change this such as the insulation R-value in the walls, attic, and windows. What state you are in also plays an important role.

3. What causes an AC unit to freeze up?

Low refrigerant potentially caused by a leak or atmospheric release can cause your AC unit to freeze up. Also, low return air capacity, as a function of the warm air going through your system is to heat the refrigerant, cool down, and be blown back into your home. Blocking or reducing the return air capacity increases the possibility of your AC unit freezing up. Finally, while uncommon, an oversized condenser can cause your unit to freeze.

4. How often should I have my unit serviced?

HVAC units should be serviced twice a year. Spring maintenance is to prepare the air conditioning system for the Summer, and fall maintenance is to prepare the heating system and furnace for the Winter.

5. How can I improve my indoor air quality?

There are HEPA filters that will improve air quality, however the best way to improve your indoor air quality is to maintain a consistent cleaning schedule of your home. Proper grooming of pets will help extend the lifespan of your filters because they have fewer particles to remove from the air.

6. How can I save more money on my HVAC bill?

Using your system a little less can drastically reduce your bill. For instance, during the Summer months, setting your thermostat a little higher, like at 75 degrees, when you are away from your home will reduce the total use of your system, thus decreasing the bill. A simple solution we offer is to install a Wi-Fi thermostat that allows you to control the temperature from anywhere. We have found this to be highly effective in reducing the bills. Of course you could enjoy a slightly warmer or colder home during the summer and winter.

7. How can I extend the lifespan of my AC unit?

It ends up being a simple combination of all of these FAQs, change your filters, keep your home cleaned, don’t force your system to run 24/7, allow proper air flow through the return vent back to your unit, and of course, get regular maintenance done on your system to catch any major issues before they cause permanent damage to your system.
