HVAC Services in Manassas, VA

Heating and Furnace Service in Manassas

Heating queries are a large part of Manassas demand: furnace repair, furnace replacement and heating contractors. When a furnace fails, the first question is whether it is a repair or a replacement, and we give you both numbers side by side. We explain gas and electric options before you commit, and financing is available, including 0% APR for up to 18 months on select units. See our furnace repair and furnace installation pages.

Heat Pump Installation in Manassas

A heat pump heats and cools your home from one system, so it can replace both a furnace and an air conditioner. We assess your house, the ductwork and the existing equipment, and we explain the full cost before any work starts. See our heat pump installation page for Manassas and our heat pump installation cost guide.

24/7 Emergency and Same-Day HVAC Service in Manassas

A system that fails in a heat wave or on a freezing night cannot wait. We provide same-day service and 24/7 emergency repair in Manassas, 365 days a year, with no extra charge for evenings, weekends or holidays. We do not quote a fixed arrival time, because it depends on the day and where our technicians are, so call us and we will give you a time when you book.

“In the middle of the worst heatwave in years, my air conditioner suddenly stopped working… I called AVS, and not only did they come out at 11:00 pm that very same evening, just a few hours after I called, they efficiently and professionally diagnosed the problem as a failed capacitor, replaced it, and had the air conditioner running again in just 15 minutes.” Rich, Google review

HVAC Repair and Replacement: What It Costs

City of Manassas or Prince William County?

Manassas is an independent city and the county seat of Prince William County, but the two are separate jurisdictions. Many addresses with a Manassas mailing city are in the county, not the city, and that matters because permits come from different offices. We serve both, and we check which jurisdiction your address is in before we start work.
