"Jermaine C Home Improvement LLC did an excellent job on a very long list of repairs and improvements including replacing damaged drywall ceilings, installing a butcher block countertop, rebuilding the side of a porch due to rotted wood, installing a new floor and trim. Overall I found the company to be reliable, honest, skilled at all aspects of home improvements, goes above and beyond and the prices very reasonable compared to other handyman companies I called. I highly recommend Jermaine C Home Improvement LLC, he definitely gets it right the first time."

"Leo did a fantastic job renovating my entire townhouse. He was originally hired to do the demo+carpentering work only, but ended up helping me oversee all other renovation work as well, incl plumbing where he creatively helped connect a vessel-sink on top of an old vanity+marble top, which increased the value of my bathroom with over 5k. He also customized and built wall-to wall wardrobes in both my bedrooms, which added so much closet space to each bedroom and the mirror doors he installed are great. The crown-molding looks great in all rooms, and the wooden floors (over 900 sqf) look spectacular! It is obvious that Leo is an expert in his field, but I also very much appreciated his advise and honesty when he ran into a potential issue where another opinion would be good before proceeding, such as consulting an electrician or plumber. Leo is friendly, reliable and professional. Once you are in agreement he will execute and get the job done quick and to perfection - and leave your place close to spotless afterwards. I would highly recommend Leo to help with any home renovation projects, small or large."

FAQs for thermostat installation and replacement projects in Cos Cob, CT

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.
