"I highly recommend Julio. He re-stained and re-sealed my wood front door. This took multiple trips to my house to put on mulitple coats and he showed up everytime, also keeping in touch about precise estimated time of arrival. He also did excellent work, with attention to detail and ensuring that he didn't damage anything else in the process. Very nice to work with and professional. Will hire again. Before and after photos attached. Any unevenness in the stain is due to nature of the wood itself; he balanced out the absorption of stain very well compared to the original stain on the door."

FAQs for thermostat installation and replacement projects in Norcross, GA

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.
