Updated October 2026
Heating season is here. (Furnace already acting up? Start with our furnace repair guide for Northern Virginia.) If your furnace hasn’t run since March or your heat pump is getting older, now is the time to book a tune-up, before the first freeze fills up every company’s schedule.
Below are 30 local heating and air conditioning contractors serving Northern Virginia, grouped by area so you can find someone close by. Most handle furnace repair, heat pump service, system replacement and maintenance plans; a few specialize in boilers and older homes.
How this list was put together: every company here is an independent, locally operated HVAC business we verified against its own website or a public business record. Nobody paid to be included, and the order within each area is not a ranking. Each name links to the company’s free DMV Business Connect listing with contact details, services and a map.

Before you book: a quick fall heating checklist
- Swap the air filter. A clogged filter is the most common reason a furnace short-cycles or a heat pump struggles on the first cold night.
- Run the heat for 15 minutes before it gets cold. A burning-dust smell for a few minutes is normal; a smell that sticks around is not.
- Test your carbon monoxide detectors if you have any gas appliances, a fireplace or an attached garage.
- Clear leaves and debris from around the outdoor heat pump unit and keep at least two feet of space around it.
- Book a tune-up in October or early November. Most local companies get booked out once the first hard freeze hits.
- Ask about maintenance plans. Many of the companies below offer priority scheduling and waived after-hours fees for plan members.
How to choose an HVAC company
- License and insurance. Virginia HVAC contractors need a contractor license from the Department of Professional and Occupational Regulation (DPOR), and the technicians doing the work need an HVAC tradesman license. You can look both up on the DPOR website.
- Written estimates. Get at least two for any replacement. A good estimate names the equipment brand, model, efficiency rating and what’s included (removal, permits, thermostat, warranty).
- Load calculation. For a new system, the company should size it with a Manual J load calculation, not just match the old unit.
- Emergency service. Ask whether they answer nights and weekends in winter and what the after-hours fee is.
- Warranty and plans. Ask how long labor is covered, and what a yearly maintenance plan costs and includes.
