" I recently had Comfair Heat and AC install a new furnace, and I couldn’t be happier with the experience. From start to finish, the team was timely, professional, and incredibly friendly. They showed up exactly when they said they would, walked me through the process, and completed the installation efficiently without cutting any corners. Their pricing was very fair compared to other quotes I received, and the quality of their work truly stands out. The new furnace runs perfectly, and the difference in comfort is noticeable already. Overall, Comfair delivered fantastic service, and I highly recommend them to anyone needing heating or AC work. I’ll definitely be using them again in the future."

"These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs."

FAQs for thermostat installation and replacement projects in Aurora, CO

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.
