Thomas J. Fannon & Sons

Thomas J. Fannon and Sons has served Alexandria, Virginia and surrounding communities including Annandale for decades, earning a 4.1-star rating across 70 reviews. The family-owned contractor employs a team of technicians who handle heating, cooling, and ventilation work for residential customers throughout the Washington metropolitan area. Their weekday hours run from 7 AM to 4:30 PM, with Saturday and Sunday morning availability for urgent calls.

What distinguishes this contractor from larger corporate HVAC companies is their approach to repairs. Reviewers consistently note that technicians explore the most economical solution before recommending parts or replacements. One customer described how the team troubleshot several options before concluding a gas valve replacement was necessary, ordering the part from out of state and completing the repair promptly. Another mentioned technicians offered a safety device to prevent the problem from recurring, explaining the cost upfront. The shop prioritizes fixing existing systems rather than steering customers toward new equipment purchases.

Customer reviews highlight rapid emergency response during critical moments. When Brian Chaplin's gas furnace failed on a cold snap Sunday, a Fannon team member took the call and scheduled him for early Monday morning service, dispatching Jack Fannon's crew within hours of the part arriving mid-week. K C received a same-day Monday diagnosis and repair after an A/C breakdown during a hot summer weekend. Tom Reynolds reported being operational within two hours during a heat wave. Each reviewer emphasized respectful, competent technicians who communicated clearly about timelines and costs.
