"I can't say enough good things about these guys! They provided same-day service (at end of June!) when the largest AC Service provider (you would recognize their name) could not schedule an appointment less than 10 days out. On top of that, Prime AC ended up replacing a 2.5 year old system which the "largest AC Service provider" installed previously which had a 1-year labor warranty. Watch out for those 1-year labor warranties, because it means the provider has no confidence in what they are installing! Prime AC recommended a solution to address the specific needs of my problem with a ten-year warranty, parts AND LABOR! They were very thorough with the install and the system works great. I would recommend this company to anyone experiencing AC issues. They are honest, hard-working, and reasonable...nice to see that still exists in some AC companies."

"Brandon and Jason checked out both furnaces. They were very courteous and explained matters clearly. Brandon explained how thermostat on one unit needed to be replaced and what needed to be done. I was very pleased with their work."

"I've been using Rescue Air for a number of years. I have never had a negative experience or interaction with any member of the company. These folks are a real pleasure to work with. The Technician that was just here, Adam, did an outstanding job and kept us informed along the way. I could not recommend them more highly."

"We're writing to say how pleased we were with Comfort Master. From the initial visit and estimate given by Roman, to the painting crew Roman and Cristina, We appreciated their professionalism and job well done! They painted the hallway, living, dining and kitchen rooms and installed crown mouldings. Roman repaired some of the small cracks and made it look like new...Cristina took care of the clean-up work too. They worked really hard and were very thorough. It was apparent to us that they took pride in their work, the attention to details made us extremely please of the quality work they do in their job. These crew is a husband and wife team, they recently moved from Seattle, WA and have two kids. We will definitely call upon them again in the future. It is great to do business with them. We are a happy customer and singing praises to them. Please call them if you're interested for a quote (206) 513 8825."

Customers say: Quality work

"Our heater fan stopped working during the cold freeze in our area. I called Tony and he was able to get his guy out quickly to replace our fan motor. The service was excellent and our problems were resolved without issue. I would recommend Tony to do any work needed around the house. He is affordable and trustworthy."

FAQs for thermostat installation and replacement projects in Denton, 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.
