Heating and Air Conditioning



Heating and Air Conditioning technology and equipment have evolved into highly efficient systems. Our local service technicians maintain the knowledge to repair today’s systems through industry certifications.
TEK7 is committed, dedicated and takes pride in same day repairs. With service vehicles in Annandale, Ashburn, and Manassas we can offer the lowest repair rates in all of Northern Virginia.
No heat on the coldest night of the year is not an option. Our furnace repair service is fast, dependable, and always low prices. And when your air conditioning can’t keep up with triple digit summer heat, an a/c tune-up might be the answer, not a costly repair.

Our growing customer base in Fairfax and Prince William County have trusted TEK7 for all of their climate control needs…keeping them warm in the dead of winter and cool and comfortable during the hot and humid days of summer. We believe that our quality products, reliable service and competitive rates, combined with honesty, integrity and professionalism is why our customers have kept TEK7 on speed dial!

In addition to conventional heating and cooling systems and service, we offer a complete line of air purification products, power generators, the latest in geothermal (ground source) heating and cooling systems, plus air duct cleaning services and home energy audits that could help you save hundreds or even thousands of dollars in energy costs.

That’s what we strive for but, in addition to keeping you warm in winter and cool in the summer we offer you, the homeowner, a variety of affordable and economical products and services to keep the air in your home clean, safe to breathe and environmentally friendly.

Whether you are considering upgrading your HVAC system, looking for ways to get more efficiency from your current system or in need of maintenance or repair, our professional staff can provide all your HVAC needs in a prompt and affordable manner.
