With more than 24 years of proudly serving from the Tarpon Springs to St. Petersburg region, our licensed and certified specialists provide unbeatable heating, cooling, plumbing, and electrical services backed by a 100% satisfaction guarantee—whether it's maintenance, repairs, or installations. Plus, you can always count on Performance for 24/7 emergency service, seven days a week.

"We had a great experience with Performance. First their Service Tech Scott came out to review our issues. He took his time and figured out exactly what was wrong. He went to great pains to demonstrate what was wrong and why we needed to replace our unit. We had a Britt come out the next day to estimate a new unit and what we needed. He was super friendly and detailed. Most importanly he listened to what we had to say and wanted. Two days later We had Bryce come and install a new unit. I love the fact had great communication with all of these guys along the way. Bryce went above and beyond installing our new unit. He actually reinforced the pedestal / box for our air handler and replaced all the lines and drain. Top notch work that really set Performance apart from the last company we used. New AC units aren't cheap but at least I feel we really got our money's worth. Thanks to all these guys for making this a easy experience."

FAQs for thermostat installation and replacement projects in Palm Harbor, FL

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.
