Aire Serv Of Clearwater is the best choice for all of your HVAC service and installation needs. With over 30 years experience, we can do it all. We take pride in our customer satisfaction. We operate, communicate and transact with our code of values focused on Respect, Integrity and the Customer experience. Call us today.

"This company does not do conscientious work. Chris seems to be more concerned with getting to his next call than spending the appropriate time to solve issues. Their work is sloppy because they do not do important things like re- taping plenums when they work on them or diagnosis beyond the 20 minutes they want to spend in your home. They do not ensure things are properly working. According to them everything is normal when you know it is not despite pointing out multiple issues when they arrive. All they worry about is taking pictures and videos to cya. They do not follow through and do a complete diagnosis and rush through hoping the problem will go away. And when the issues gets worse or they cause more problems they deflect and blame it on something else and gaslight you. Diagnosing via text is a thing now I guess. Now I have to pay someone else to fix their mess. 27 days later it is an ongoing problem and still broken and they will not respond. "

At Performance Air Conditioning, Electrical & Plumbing, customers will find a team of highly-skilled, fully licensed, and insured technicians who can provide a comprehensive range of home services. Whether you are looking help handling HVAC repairs, water heater installation, electrical safety inspections, drain cleaning, or anything in between, you can count on this Clearwater home service team. They have proudly served clients throughout the community since 1959 and are available for service 24 hours a day, 365 days a year. This is a team of reliable, professional experts who are committed to doing a thorough job and ensuring that you have everything you need. Call the office today to learn more about your options!

"My review has not appeared on the Performance Air primary site which consists of positive reviews, so I'll try to replicate here. I've also contacted the BBB. Company ads indicate "service 24/7" which is misleading. Yes, you can speak w/ someone at the company, but they can't or won't send a tech 24/7. Our a/c went out Sat evening, 9/16, and they said someone would be out Tues, 9/20. When I said that won't work they scheduled us for the next day, Sunday, between 10a and 2p. Needless to say they didn't show. I called dispatch to see when someone would arrive and was told the tech was delayed on another job. Finally about 5:30p I was told "you're not on the schedule." A wasted day in the heat when I could have called someone else. Our Trane unit (bought from Performance) is less than 8 years old and is maintained only by Performance Air via a service contract. The company is eager for us to replace the unit. When Trane and other brands are properly maintained they typically last much longer than 8 years. The company overcharges on parts, which I've called them out on and had the price reduced (check the records if they'll let you...you have our permission.) Hughes Gulfport FL"

FAQs for thermostat installation and replacement projects in Largo, 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.
