"I am so pleased with my choice to hire Wesling Electric. Robert was polite, professional and easy to work with. Of the three bids I received for my project, his bid was in the middle price-wise. I was confident hiring Robert because he seemed very competent and would be the same person who would be coming back to do the work. I didn't have to worry about job details getting mixed up or miscommunicated between a project manager and worker. As of March 2022 Wesling Electric was booking one week out (this was the same timeframe for all 3 companies I spoke with). The job took less than a day. Robert confirmed how I wanted the new switches to work and didn't mind me being picky with the placement of a ceiling fan. I will definitely contact this company again for future electrical projects in my home."

"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."

FAQs for thermostat installation and replacement projects in Silex, MO

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.
