"My front door was hung in a crooked door frame and would not close or lock all the way. I also needed to install 2 new storm doors, one in that crooked door frame. I’m on a limited budget, and Nixon was able to correct the door lock situation, compensate for the frame, and install the storm doors beautifully. Everything now works perfectly and looks amazing. He recommended the perfect storm doors and hardware and even picked everything up for me. It was all finished in 2 hours! Highly recommend!"

"Rafael replaced my gross old linoleum floor with subfloor and LVP, replaced the toilet and vanity, and finished the floor work with a quarter-round trim. The finishing work was well done; the floor was in bad shape and he fixed it and made it look amazing. If I had more $$ I would have had him redo the entire bathroom. Rafael arrived early, worked the whole day, and consulted me on every step of progress made. Rafael was always professional, polite, respectful, and well-tempered. I have had workers who have come in with foul language, loud music, and on their phones the whole time. Rafael is a rarity - he and his co-worker completely respect the client's home. I definitely would hire him again!"

"I needed an electrician to install a 240 volt outlet quickly for an electric dryer coming on Monday. And didn’t know who to use, so went on Angie's List and found Ohms Electrical Services, who responded back within a few hours of calling and was able to come the next day. Lloyd was the electrician, who came and did a great job. He knows his stuff and if very personable and professional. He also saw work a past electrician had done that was not to code and explained why and that is was a safety issue, so will be having him back soon to fix that as well as other projects. Definitely, would recommend and very reasonable price."

"Mr. Electric was very professional. Him and 2 of his associates installed 2 Nest thermostats in my home, which required additional work as I was initially on a line voltage. He took his time explaining what he would do, was very courteous and professional. He was on time during the initial assessment as well as the actual installation. Very meticulous in their work, cleaned up everything and even showed me the details of their work. Would never hesitate referring them and contracting them in the future. Keep up the great work, Kato!"

"We purchased a package for tile repair. We were told that the repairs would far exceed the package deal. The estimate given for a full replacement of the shower was close to twice that of the next two people who came in.

"Melvin came over the same day I called for an estimate and he was very clear about what he would do and how he was going to do the job.  After a couple of weeks of getting to convince my husband (he was against putting the tv over the fireplace), we called Melvin to do the job and he came over on a Sunday. I was pretty surprised since you never have anybody working on Sunday unless is an emergency.Our house was built in 1929 so is pretty solid construction around the fireplace.  It was a tough installation and he even had to cancel a couple of appointments he had for that day, that's how hard the job was (he arrived at our house at 11am and left until around 7pm) because the usual method Melvin used didn't work since there was no way for him to pass the cables down thru the floor and then up again, so he had to drill to the wall and bring the cables thru horizontally thru the wall, but he did it wiht the minimum amount of mess and even patch up the hole once he was done.  My husband is the pickiest of them all when it comes to anybody doing jobs around the house, but he was pretty satisfied with the work that Melvin did and now he loves the way the tv looks above the fireplace.  We had friends over a few weeks later and complimented how clean the job was done and how nice it looked.  All in all, we're very happy and we will definitely call Melvin when we're ready to install our A/Cs or do anything electrical. Melvin is a true professional and one of those rare people out there that takes real pride in a job well done and will not walk away until you're satisfied with his work.  It only took me a bit of time to get to post the review because I was waiting for the bookcases to put on either side of the fireplace and give it the finish look to upload the picture.
Thanks so much Melvin for a job well done!

"The service was great. They gave a lot of really helpful suggestions. They replaced our bulbs with low energy bulbs. They put in weather stripping in areas needed as well. They were great to work with. They gave a detailed report on how to lower our energy usage."

FAQs for thermostat installation and replacement projects in Sherman, 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.
