"The whole process was a lot less inconvenient than I thought it would be. The estimate was far below other companies I had contacted. Glen knew exactly what I would need in my house. He has serviced Sun City homes for a long time and his assessment was quick and accurate. Other companies spent an hour trying to figure out what kind of system I would need. The installation was also easier than I thought. I did not have to move anything. They covered every thing that might get dusty. There was absolutely no mess when they left. I’m still waiting for my inspection. But everything appears to be working quite well."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"5-Stars for Shawn at Precision Air! We were looking for a dependable and experienced HVAC technician when it came time to replace our furnace and add AC. We discovered Shawn at Precision Air and couldn't be happier with our choice. Shawn was incredibly professional and responsive from the start. He listened to our requirements and explained all of our choices. He also provided us with a detailed and reasonable quotation. Shawn got right to work on the day of the installation and arrived on time. He took great care with his work and made sure everything was done correctly. He also took the time to instruct us on how to use our new system. Even after the installation, Shawn's follow-up was excellent. He contacted us many times to guarantee that everything was working effectively and to finish the final inspection after being paid. For all of your HVAC requirements, we strongly suggest Shawn at Precision Air. He is a real professional who is proud of his work and who we will surely hire again in the future."

FAQs for thermostat installation and replacement projects in Cool, CA

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.
