"Use Caution: The only thing the technician they sent was qualified to do is sell you a product or service. He first tried to sell me a new &12k unit plus $4k duct cleaning. When I declined, next was a $6k evaporator coil replacement and the $4k duct cleaning. When I refused, he next peddled $2k evaporator coil cleaning and $4k duct cleaning. He continued trying to sell me a lower priced solution to the problems he found with the HVAC system. His last attempt was to sell me an annual service contract for $240 and he was successful. However, the lies he told to accomplish this were extremely deceitful. He produced pictures showing the system low on freon (4lbs) and his leak detector reading 99% leak detected. He would be graciosos and put 2lbs of freon in the system if I purchased the maintenance contract. He stated that my system would only work for a week before the freon leaked back out. (1 Week Later) Concerned called a different HVAC company to service my system (Tropic Aire). The technician checked the system from the compressor to the atic. The only thing he suggested was to have the outside compressor enclosue debris cleaned out. No leaks, freon at 100%, and no problems with the ductwork. Do not believe their people, they will miss lead you and destroy your HVAC system."

FAQs for thermostat installation and replacement projects in Jacksonville Beach, 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.
