McKinney's HVAC Replacement & Service Specialists
Metroplex Air & Heat serves McKinney out of our Frisco location — where our duct-sealing and rebalancing jobs are most requested.
about 15 minutes from our Frisco base
McKinney generates our highest volume of duct-sealing and rebalancing work, especially in Stonebridge Ranch and Craig Ranch, where long duct runs to back-of-house additions lose airflow before it ever reaches the vent. Historic Downtown McKinney's older homes usually need something different: a full duct redesign, since the original ductwork wasn't built for a modern high-efficiency system.
"They found and sealed duct leaks two other companies never mentioned. Wish we'd called them years ago."
Stonebridge Ranch and Craig Ranch AC replacements often reveal duct issues we catch during the same visit.
Historic Downtown McKinney homes usually need a full ductwork assessment alongside any furnace replacement, since original ductwork rarely matches modern system airflow requirements.
McKinney generates our highest volume of duct-sealing and rebalancing work in the entire service area.
Solving a Craig Ranch Home's Weak Back-Bedroom Airflow
A Craig Ranch homeowner convinced their AC unit was failing because two back bedrooms barely got any airflow.
Diagnostic testing found significant duct leakage in the attic run feeding those rooms, not a failing unit.
Sealing and rebalancing the ductwork solved the airflow problem entirely, at a fraction of the cost of a new system.
In most cases we've diagnosed, it's duct leakage or an undersized run feeding a room addition, not a failing unit, which is why a duct-sealing and rebalancing visit often solves it without a new system.
Frequently, yes, original ductwork in pre-1980s downtown McKinney homes usually can't move the airflow a modern high-efficiency system is rated for, so we assess duct capacity as part of any replacement quote.
Not usually. In most McKinney homes we've diagnosed, weak airflow in specific rooms comes from duct leakage or an undersized run, not a failing unit, which is why we run diagnostics before recommending replacement.
Duct sealing and rebalancing in McKinney typically runs a few hundred to just over a thousand dollars depending on how much of the duct system needs work, far less than a full replacement.
