MASTER HVAC License We take great pride in offering the best possible experience with our expertise, quality, and customer service. In order to understand the needs and expectations of our clients; we take great care to work and communicate with everyone in a professional manner. It is our mission to exceed our clients expectations by providing excellent workmanship and complete customer satisfaction, from the start of each project to its completion. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"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 called home sweet home about a broken furnace. Sammy live close by and came right out on a Sunday morning. He explained what was wrong with the furnace. He didn’t think I needed a new furnace just some parts. He was able to get the furnace started again And will call me about the parts in the morning. Sammy was most helpful and personable. He explained everything. I felt I was in good hands with him."

FAQs for thermostat installation and replacement projects in Ashburn, 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.
