"Junior and Willie replaced the coil on our A/C. They explained everything they were going to do and showed us why the coil needed replacing. They were very professional and polite, wearing shoe covers because it was wet outside. They kept the appointment on time and did the work in a timely manner. I would highly recommend this company to anyone needing a/c work."

"A little inexperience with my particular faucet caused the genttleman to give some incorrect advice but it was minor. Great customer service otherwise and nothing that a few more years of experience won't fix. Friendly and customer focused. I would definitely hire again and will."

FAQs for thermostat installation and replacement projects in Austin, 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.
