"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."

"Incredible experience. Matt and Miseal came to my 1960s era condo in rural CT to do an assessment of what I wanted. Matt (a veritable genius) recommended in order to save time (labor $) and to help bring my aging condo into the 20th century, to install the new Lutron Caseta system. Turns out, it’s Alexa, Google, and Apple compatible, in addition to just being wireless. Over the decades, Ive wired outlets, switches, ceiling fans, and fixtures of all types many, many times. This system is light years ahead of “old school”. With a simple Echo Dot or Echo Show and the affordably priced Caseta bridge, even my adult son could easily control my lighting and ceiling fans from his house or anywhere in the world. Incredulous! This system actually becomes part of your environment, so to speak. Anyhow, I got the quote a day or so later from Equipment Unlimited and was “dead nuts” right where I thought it would be and thought was reasonable. 1 week later, everything is done, working perfectly, not a single glitch. Again… incredulous. Matt and Miseal were neat and tidy, which was great because their working with me there did not ignite my OCD. Cleaned and used a tarp as they went from one area to another. If you’re looking to electrically update your home, consider yourself freaking lucky if you get Matt and Miseal. Personable, clean, on time, reasonable and yes, even a sense of humor; a rarity among electricians. EXCELLENT JOB, Matt and Miseal from Equipment Unlimited. You made this old swamp yankee a very happy guy."

"Installed the bathroom fan/light which wasn’t super easy, they had to crawl through insulation in the attic. Also changed out the broken switch on the outlet while they were there which was nice. Not terribly pricey"

FAQs for thermostat installation and replacement projects in Fairfield, 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.
