"Sometimes you find a contractor that is a professional but rarely can you call them a friend once the job is completed. Gary is that. He’s patient, listens and delivers on the project game plan. I hesitated to write this post because I don’t want him to get too busy lol but it’s best to share when you find a great contractor so others may benefit so here you go. Call Gary, but an allocate more than 10 minutes on the phone lol. And that’s a good thing. Pictures to follow."

"Mauricio B and his assistant were fantastic! They installed two ceiling lights, keeping us informed and asking preferences throughout the process. I will have to request Mauricio on any additional jobs. Highly recommend!"

"They first charged me an outrageous amount to figure out why my door was leaking and didn?t. They sent someone else to look at it. Who did figure out what was wrong . When they did come to fix the door, they did good work, but they charged me an outrageous amount of money to do it. They quoted me as having to rip up my whole deck to replace flashing. But when they came out to do it, they only had to pick up a couple boards .and redo the frame on a door and they charge me an astronomical amount of money. I am not happy. I will not be using them again. "

"Outstanding work yet again. We had our bathroom lighting replaced and Mike performed another great job. Came out to meet with us, went over the details of the job and knocked it out in the right time at the right price and as always the work was fantastic."

"Sam is very friendly and understanding, ensuring that every step in the process was done correctly, and even did things that he didn't have to do, but he did anyway. He really went the extra mile for me. He's been doing this for a while, so if you're looking for experience, this is your guy. Great technician, highly recommended."

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"I had an excellent experience with Kevin. He installed a very large and complex crystal chandelier in our foyer, and the entire process was handled with exceptional professionalism and precision. This was not a simple installation,the chandelier is heavy, intricate, and required careful assembly and mounting at a significant height,but he approached the job with patience, attention to detail, and clear expertise. He took the time to ensure every component was perfectly aligned and secure, and the final result looks absolutely stunning. The installation was done safely, efficiently, and with great care for our home. I would highly recommend him to anyone needing electrical work, especially for challenging or high-end lighting installations. Truly outstanding workmanship."

FAQs for thermostat installation and replacement projects in Great Falls, VA

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.
