A system that runs constantly but leaves one Fairfax room hot, feels humid indoors, or drives your bill up isn't broken — it's underperforming. We measure instead of guess.
Not every Air Conditioning Repair call in Fairfax is a broken system — plenty run constantly, cool unevenly, or leave the air feeling clammy. We check static pressure, return sizing, and refrigerant charge together, since comfort complaints are rarely caused by just one thing.
