"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

"Probably some of the best customer service and work I’ve ever had done. From the first phone call to Wired Installations, through the work, and finally to when the last tv was hung everything went smoothly. All of this was done with patience and good old experience. My first contact with Matt (the owner) was when I called to ask about hanging a couple of tv’s on the wall. After discussing the locations, he felt this would not be an issue. He asked if we had purchased the tv’s yet – which we hadn’t, and in turn he replied I will match anyone’s legitimate price. I certainly could not go wrong there. He and Marcus showed up on time with my 2 new tv’s and began unboxing and locating them to their respective rooms. Two hours and some change later both tv’s were up and producing a good evenings worth of entertainment. I would highly recommend Wired Installations for any tv installation, or anything electronic. Thanks for such a GREAT experience!"

FAQs for thermostat installation and replacement projects in Charleston, 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.
