According to the Environmental Protection Agency (EPA), geothermal systems are the most energy efficient, environmentally clean, and cost-effective space conditioning systems available today. Simply put, a geothermal system moves the heat from the earth into the building in the winter, and pulls the heat from the building and discharges it into the ground in the summer and/or is used to heat water. An underground series of pipe loops serve as a heat source in the winter and a heat sink in the summer. We will show you how to tap the earth's free underground energy treasure. Call Today!

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

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.

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.
The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.
Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
