About TEK7 Heating & Air Conditioning
TEK7 Heating & Air Conditioning has earned a 4.9-star rating across 155 reviews, establishing itself as a trusted name in Northern Virginia's HVAC service landscape. Serving communities including Annandale, Burke, Ashburn, Chantilly, Vienna, Manassas, and Fairfax, the company handles everything from routine maintenance to complex system replacements. Owner-operator Kim leads the team, bringing hands-on expertise to every service call.
The company distinguishes itself through factory-authorized partnerships with Bryant, a manufacturer known for durable boilers, geothermal heat pumps, and oil furnaces. TEK7 offers PerfectAir Solutions for homeowners prioritizing indoor air quality, and maintains a stock of small packaged systems for tight spaces. TheirSameDay repair commitment and upfront pricing model set them apart from competitors who quote vague timelines.

Andrew Peters faced a Christmas-weekend breakdown where two larger companies quoted excessive prices and unavailable parts; Kim diagnosed and repaired the system in under two hours at a fraction of the cost. Nury Turkel described a sweltering summer scenario where Kim arrived early, diagnosed a failing AC unit, and restored comfort within hours.
