TEK7 Heating & Air Conditioning - Annandale's Local HVAC Repair

We are experienced with all major HVAC brands commonly found in Northern Virginia homes, including Lennox, Bryant, and Trane. Whether you need a repair for your current system or a full installation, our technicians are trained to work with these and other leading manufacturers to ensure reliable performance.

Uneven temperatures and excess humidity are common issues in our local climate. We start with a thorough inspection of your ductwork, insulation, and system capacity. Solutions may include sealing and balancing your ducts, recommending a properly sized unit, or adding a whole-house dehumidifier to work with your AC, ensuring consistent comfort and efficiency throughout your home.

Our maintenance service is designed to prevent problems and extend your system's life. It includes cleaning coils and components, checking refrigerant levels, inspecting electrical connections, testing safety controls, and calibrating your thermostat. Regular maintenance helps improve efficiency, lower energy bills, and reduce the likelihood of emergency breakdowns, especially during our hot, humid summers.
