AC Installation and Replacement in McLean

Replacing an air conditioner is a large decision, so we explain the options before any work starts. We look at the age and condition of your current equipment, the ductwork and the thermostat, and we give you the full cost in writing. Call for a free replacement estimate, and ask about financing, including 0% APR for up to 18 months on select units. See our AC repair cost guide for typical repair prices, and call to compare against a replacement.

Heating Installation and Maintenance in McLean

Heating installation and maintenance searches are a steady part of McLean demand. Maintenance finds small problems before the first cold night, and a new heating system is best planned in the off-season, not during a breakdown. We install and service furnaces and heat pumps, and our VIP Program covers a high-efficiency system, annual maintenance and 24/7 emergency service for one monthly payment. See our heating installation and heat pump maintenance pages.

Thermostat Repair and Installation in McLean

A thermostat that is blank, unresponsive or reading the wrong temperature can look like an AC or furnace failure, and it is often a quick fix. We repair, replace and install thermostats, and we check that the new thermostat works with your system before we leave.

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 McLean, 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 We do not quote a fixed arrival time, because it depends on the day and where our technicians are, so call us and we will give you a time when you book.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

Permits and Local Rules in McLean (Fairfax County)

McLean is in Fairfax County. The county lists new, replacement, repair or conversion of HVAC systems among the projects that need a mechanical building permit, and replacing a gas or oil appliance such as a furnace or boiler needs a Household Appliance permit and an inspection, even for a like-for-like swap. The county recommends that a properly licensed contractor pull the permit, and Land Development Services can be reached at 703-222-0801. We confirm permit requirements before we start work.
