"As an elderly couple, going without air conditioning for two days in this heat was incredibly difficult—and honestly, a little scary. We reached out to Sweatman’s HVAC Plumbing & Electrical, LLC, and he didn’t waste a second. He came out right away, without hesitation, and got us taken care of immediately. What meant the most to us was how he treated us—with kindness, respect, and urgency. He didn’t make us feel like “just another call.” He made us feel important, like family, and that kind of care is hard to come by these days. He did the work quickly and professionally, and we were back to being comfortable in no time. We’re so thankful for his compassion, honesty, and dedication. If you’re looking for someone you can truly trust, especially as a senior, look no further than Sweatman’s. He is a blessing."

"Mr. Mike is truly an honest and very admirable handy man. He is true to his word and explains to you everything he is doing on your home remodel project. He listens to you about everything you want in your remodel plans. I was very nervous to find someone to help me redo my front main bathroom again after the first contractor never showed back up to finish the job. Mr. Mike showed up on time. He looked at my floor and looked at my bathroom. He immediately knew I had a water leak. The tile grout was all cracking on the bathroom floor and the bathroom had a terrible smell like old wet rotted wood. Mr. Mike gutted the bathroom again told me there was no rubber liner used for the shower and I had black mold. I was so upset, but Mr. Mike was so nice and calm which made me feel better. He basically rebuilt my entire bathroom. It only took him 5 days. He also found electrical wires by my water lines!! I am over the moon happy about my new bathroom and beautiful floors throughout my whole house. He also installed new interior doors. I loved the guys work and honesty so much that I redid another bathroom in my back bedroom. Mr. Mike is a handy man keeper!"

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.
