Uneven cooling is a common issue we see in many Plano homes, especially larger ones. The cause can range from an undersized or aging HVAC system, ductwork that's leaky or poorly designed, to a malfunctioning component like a zoning damper. Our technicians are experts at diagnosing this local problem. We'll assess your entire system—from the air handler to the furthest vent—to identify the root cause, whether it requires a repair, duct sealing, or discussing a more appropriately sized, energy-efficient installation to evenly cool your entire home.
