"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!"

FAQs for thermostat installation and replacement projects in Killeen, TX

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
