Brennan’s Heating & Air Conditioning has run out of Woodbridge since 1979, and it has stayed family-owned that entire stretch. Heating and cooling is the only business it does, and the work is weighted toward residential sales, service and installation.

Service reaches across Prince William and Fairfax counties, plus Stafford, Manassas, Gainesville, Alexandria and Arlington. Dedicated pages exist for Woodbridge, Alexandria, Arlington, Fairfax, Manassas and Springfield, and the company also lists Annandale, Dale City, Dumfries, Fairfax Station, Lake Ridge, Lorton, Oakton and Reston as covered.

Equipment coverage spans gas furnaces, heat pumps, air conditioners, water heaters, ductless and zoned systems, fan coils and evaporator coils, thermostats and controls, and ventilation. Ductwork is handled end to end: new duct installation, repair and cleaning. Indoor air quality is its own service line, with air cleaners, filters, purification systems, humidifiers and dehumidifiers offered against allergens, pet dander and pathogens. Planned maintenance agreements are available, and emergency service runs 24 hours a day.

The credentials are specific. The company holds a Class A Mechanical and Gas Fitters contractor license, Virginia number 2705 020470A, and is licensed, bonded and insured. Technicians are NATE-certified and EPA-licensed. Brennan’s is a Carrier Factory Authorized Dealer and has taken the Carrier Presidential Award every year from 2014 through 2026. It has been BBB accredited at an A+ rating since 2002. Trade affiliations include ACCA, the Quality 1 Service Network, the Washington Gas contractor program and the Dominion Power Contractor Network.

Two operating practices set expectations for a service call. Brennan’s charges by the job rather than by the hour, and technicians quote the price and lay out options before starting work, so there are no hourly surprises or last-minute add-on fees. And every technician puts on shoe covers before stepping inside a home, a small policy the company states plainly.

Financing is available, coupons and seasonal specials are posted, and the work is backed by a 100 percent satisfaction guarantee. Same-day service is offered across the Northern Virginia footprint. The office is at 2608 Morse Lane in Woodbridge.
