"I've been hiring Tony from Cold Air Mechanical for about 10 years. First for my apartment management business when my on staff techs couldn't figure out the problem and then at my home. He's always very pleasant to work with and very knowledgeable. Where I've had other HVAC techs try to sell me unnecessary equipment for outrageous prices (thank you Private Equity), he's actually identified the problem and usually has the part in his van at a fair price. While I'm not HVAC certified, I know my way around and I'd definitely recommend Tony."

"Theo, the owner is great as an HVAC pro. We asked him to come out for the tune-up going into the summer season. He checked, very thoroughly, both our units. One was good to go, but the other one needed 6lbs of freon. Theo explained everything and showed us everything that he checked. He even tried to work with our home warranty company to see if they would cover the cost of repair/replacement, but they would not. Theo gave us our options and we asked him for his honest recommendation. He said a new unit. Ours is nearly 20 years old and has been repaired several times recently. We went with a new unit and he was able to install it within two days of us talking. He made sure the installation was smooth and with minimal interruptions. His thoroughness have us feeling better about our decision and trust in his judgement and professionalism. Very good HVAC pro and a good guy to do business with during these times."

"The tech was very knowledgeable and skillful. He had to install the new blower fan into the existing fan housing, but he took the existing blower assembly (fan, motor, electrical, and housing) out to his truck in inclement weather to do the work. I offered up my garage, but he said that he would be fine out in his truck. From start to finish it could not have been more than 40 minutes. The blower unit runs and sounds like a brand-new install. Very quiet. Prior to the repair the blower sounded like a freight train passing through the house. Very happy and the cost was reasonable."

"It's that time of the year! They are local (Kempner), like and follow their page. Native Heating and Air LLC truly impressed me with their exceptional service from start to finish. Melanie and her team provided flawless installation, competitive pricing, and a comprehensive maintenance plan. Despite receiving multiple estimates, Native stood out and won the bid with their expertise and dedication to customer satisfaction. Most importantly, there were no annoying sales pushes, which was a refreshing change and a big reason why I switched my former HVAC provider. Special thanks to James from the City of Copperas Cove - Municipal Government building inspector for his professionalism. Additionally, I must commend Josh, the owner of Native, for his act of kindness and honesty. He went above and beyond by pointing out a minor cosmetic defect in the unit that I hadn't noticed during inspection. He chose to do the right thing, which resulted in him replacing it with an intact unit from the distributor located out of town to ensure my satisfaction - all done the same day! For all your HVAC needs, choose Native Heating and Air! You will not be disappointed! Call them for any maintenance, repairs, replacements or new installations. I'm very happy!"

Heating and Air Conditioning FAQs, answered by experts

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.
