"I hired Mr. Handyman to replace a shower faucet. The co-owner, Bob, came out for the estimate as well as the job itself and he was wonderful. He was punctual, professional, and kind, and most of all he did a great job! You could tell he's amassed a lot of knowledge in this profession because it showed in the quality of work he performed. I would absolutely hire this company again and plan to for future needs."

"Did a great job. Called him at 2pm to fix. I asked if he could come out to home at 430pm to fix (wife could be there then). He made it right at 430pm. When I called at 2pm and from my description over the phone, he was able to give range for price (he said roughly $60 to $80). It ending up costing $60 (lower end of what he said over phone). Can't get better than that. I recommend."

"This is a great trustworthy company. We had used them over the years for patching jobs and when it was time for a new roof, had no qualms about hiring them. They completed the job in a day and a half and cleaned up after themselves completely."

"Tom Scharfenberger met us as scheduled and gave us good advice and pointed out many technical points that helped us pick good products. He promptly provided a quote and once accepted came back with the installers, Scott and Terry, to make final measurements prior to submitting the order. The installers were superb and dealt well with many challenges, resulting in a near perfect installation that looked great requiring no additional trim work and resulting in a marked improvement."

FAQs for thermostat installation and replacement projects in Alton, IL

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.
