For all inquiries, please call or text (703) 281-4185. Will not respond to emails or messages through the message center. We have been serving Northern Virginia since 1992. We have Virginia class B license for projects up to $120,000, but will do virtually any project or repair inside you home. We do have a $175 minimum house call fee that includes the first hour of work. After that it is $75 per hour fee for smaller projects. Larger projects are based on a lower hourly rate which is included in the over all project estimate. The cost is generally determined by the job but some areas such as exterior carpentry may be billed hourly due to the unpredictable nature of the work. We may find more work up close or underneath visibly damaged areas. All employees speak English well. We are also able to communicate in Spanish, Cechua or Italian (just in case). We are covered by general liability insurance, disability insurance, workers comp, and heath insurance. I treat my employees and my customers, in the same manner I wish to be treated myself. We have been Angies list supper service award winners for the past 11 years. We care about our workmanship and our customers and I think that is reflected in our awards. Thank you for considering us for your projects.

"Will and his team are knowledgeable and responsive, a trusted contractor! He resolved several plumbing issues and replaced smoke detectors throughout the house."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
