"Mike arrived on time and began work immediately. He removed old wiring and installed all new wiring and conduit and repaired a few down spouts at the same time. He installed all new lights along the walkway, removed an outlet that was of no use and re-wired the entire front of the house including wall flood lights. Mike had to dig up flower beds etc. to accomplish his work and when he left you would not know he was ever there. He cleaned up the walkways and removed all trash. He kept in touch with me regarding progress. I have used them several times for non electrical issues also. Their communications system is top shelf. They always call back, confirm appointments and follow up on their work. All of their techs are professional, courteous and respectful of your property. I feel their prices are fair. I would highly recommend them for all your needs."

FAQs for thermostat installation and replacement projects in Malvern, PA

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.
