Why does it seem that the worst plumbing or air conditioning problems happen when you least expect it? Your AC fails in the middle of a record heat wave, you find a water leak right as you're leaving for vacation, or your heater stops working in the dead of winter. Whether you need routine maintenance to prevent such issues in the first place, or a trusted technician to handle a plumbing or air conditioning emergency, you can trust the team at Five Star Plumbing Heating Cooling.

"Had an issue with a system 5 Star installed in August (7 months ago). They came out in 3 hours, and in 5 minutes realized that an electrician (separate project) had flipped off the wrong breaker. Had me up and running immediately. Cannot recommend 5 star enough for all HVAC work"

FAQs for thermostat installation and replacement projects in Greenville, SC

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.
