"It was our third time using The Handy Veteran and it will not be the last. Kevin and his team are absolutely top notch! Our first job with Kevin was to replace and paint all of the wood and trim in our entire house, replace carpet with LVP flooring on a third of the floors in our 3000sqf home, refaced our fireplace, install a new front door, & paint the entire house. Second job was to repair and paint our large deck. This last job was to replace more floors, remodel our guest bathroom and hang multiple lights fixtures. Our first job was in 2020 and the initial work they did is still perfect. Kevin stands by his work. He is not satisfied until the job is done right and was extremely accommodating to all of our requests. He wanted us satisfied and happy with the work and even made some great suggestions that really enhanced the final outcome. Him and his team are extremely respectful of our time, professional, friendly and trustworthy. Also very fair with their pricing! "

I’ve been running my own handyman business for about 4 years. I have work in most of the trades in my life. I have experience with roofing, plumbing, general repairs, and assembly of furniture. Estimates are always free.

"I?ve waited to right this as at first going to let it go. Work was not completed correctly at all. We agreed to replacing the fascia boards paint and seal(as is normal). He bought some pre-primed boards and some not painted and only painted unpainted. The pre-primed never got painted. Only sealing done was where a huge gap was on certain spots. All were sealed prior. The owner, after agreeing, wanted a whole week when tempts at 60+ and started when temps dropped to 40. Often didn?t come had to send texts and even asked if he could do it after all. I will have to spend close or double what he charged to have it completed by someone in spring. Now the worst part my AC is possible damaged beyond repair. The company I use won?t even look at it till spring since can?t at these winter temps. He dropped a board from 20? up that hit the unit so hard on the top that 8? from the impact spot bent the housing so bad fan won?t spin. Something under spot is effected, probably compressor. "

FAQs for thermostat installation and replacement projects in Saint Charles, 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.
