"Jim the Handyman is fantastic! We recently had several small repairs done (we waited to bundle them into one job to make it easier for everyone). The crew they sent out did all of them in less time than I expected, and for less than half of what I expected to pay. The work was top notch (something we've seen in the other things they've done for us) and we are very pleased. In fact, I have to call them to schedule some other work. Jim the Handyman should be your go-to provider for anything you need done."

"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

"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."

"Ruben and his team were excellent from the beginning of our bathroom renovation to the end. Ruben provided a thorough consultation at our home, let us know about the timeline, and worked with us to ensure we had the materials we needed (we procured some we wanted to pick out and we procured others that we needed help with). He provided good recommendations during the project, kept us updated, and ultimately finished the project within the timeframe he gave. We were really happy with the quality of the finished bathroom and we would definitely recommend Two Brothers."

FAQs for thermostat installation and replacement projects in Fairfax, 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.
