"Replaced our Air Conditioning unit on our four story condominium unit that included renting a crane. Their estimate was on average 30% less than their competitors. Courteous and professional team that replaced our AC unit. We will be hiring them in a month or so when our current Annual Maintenance Contract expires. Call them, you will not be disappointed."

"This is the second big project we've done with REO Service Pro. They finished our basement a few years ago. Both projects were done with quality and professionalism. Gary is very easy to work with. He listens and offers suggestions when needed or appropriate. I also used an interior designer with whom he worked with ease. We had an aggressive time frame for this project and it was met. Our two favorite things about working with Gary and his crew are 1) their quickness in responsiveness and 2) quality control. On multiple occasions I witnessed Gary instructing a crew member to "rip it out and start all over". In our experience with house projects, that is a rarity. Most contractors are okay with mediocre work to save time and effort. As a result, the end product was great. In terms of cost, they may not be your cheapest bid but they won't be your most expensive either. The investment is worth it. I highly recommend REO Service Pro."

"My experience with Jim the Handyman was great from start to finish. They responded to my initial inquiry promptly, sent someone to thoroughly assess the necessary work, and then met and exceeded my expectations when completing the work. I needed several repairs to set of French doors. One company wanted to replace the entire door set for $3500. Jim the Handyman did only the necessary work for $285. I appreciated not only the quality of the work, but the honesty about what was required. I'll now use Jim the Handyman for a variety of projects around the house when they come up. Kudos!"

"Josh came to provide an appraisal and he quickly understood what needed to be done and provided a solution. Jose came out quickly and widened the opening so we could get our furnace serviced and our heat turned on. Jose returned and within 4 hours had the electrical outlet moved, new framing complete and painted, floor tile replaced, and new doors installed. I am very impressed with the service provided by JW and will contact them again for any needed repairs."

"Beyond my expectations! The old door was condensing inside and out, we knew there would be extensive damage to the wood framing and floor area beneath. It was worse than I expected. Mike installed the new door, created a way for our pet door to fit while still being able to LOCK the slider! Over three days - the tear out, purchasing of many materials, repairing the frame, installing the new door, repainting/restoring the interior and exterior to BETTER than they previously appeared, and rigging that new and improved pet door - he worked diligently. I have never had a workman that was so neat! Cleaning up debris, bagging trash, maintaining the work area organized and safe. I have already recommended him to friends, and they have all said how great he was! I have many other projects planned, and will not hesitate to call Home Remedies again."

"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."

Hello!!! I’m Alex Ruffing, welcome to my page! \n\nI’m a born & raised Northern Virginian with 19 years in construction services (and counting). I started young, with family, on area commercial jobs; Wolftrap, Metro Garages and Park & Rides, and many of our shopping plazas. Then spent some time traveling the east coast building in the industrial sector; concrete, sky rises. Now I am happy to be home and operating as a Handyman(+). \n\nHandyman because I mostly operate independently, preforming all kinds of repair and remodeling opportunities. \n(+) because I am well connected with reputable tradespeople in the area, and I always happy to discuss larger residential projects; backyard pavilions, outdoor kitchens, shotcrete pools, additions, movie theaters, bars, and wine cellars. \n\nMy cell phone is (571)320-8605. Do not hesitate to call or text so we can discuss solutions regarding your home’s next repair, remodel, or improvement. \n\nWith best wishes, thank you. I look forward to hearing from you.\n\n

"Timely, professional, and personable technician. Provided options for repairs and coordinated an assessment for replacement of system. I’m a customer that was moved with the sale of A-One to John C Flood and I am happy with the transition. The work was on my HVAC system, but that was not listed in the drop down."

"Added dedicated circuits for future sauna and cold plunge. Work was done in a timely manner and cleaned up after they were complete. Minimized hand holes in drywall and left clean cut pieces to make future patching easy. Communication throughout was very good."

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.
