"Needed a new thermostat installed because my other one didnt work right. He came out, put a new one in, made sure it worked fully and completed the job. Have had no issues with my new thermostat. Scott is friendly, knowledgeable, and down to work. I appreciate his help."

"Worked with Kurtis who was very accessible and easy to work with. He answered all my questions with honesty. The install was very easy to schedule and the guys did a great job. Cleaned up behind themselves in the basement very well, but left a little dust behind with installing the new thermostat. Overall, I was very pleased."

"Reed did a great job. On time, professional, reliable, at a fair price. I had him replace two frost proof sillcocks for me. I turn 67 soon and I found my handyman for things I should no longer be doing."

"Barry did a variety of things at our home. Gutter, siding, window and door repair. Drywall repair and painting. He even repaired our bathroom exhaust fan which we thought we would need to replace. Everything looks great! We will definitely call him in the future and would not hesitate to recommend him."

FAQs for thermostat installation and replacement projects in Indianapolis, IN

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.
