St. Louis HVAC Company | Fix Uneven Cooling & System Sizing | Finley

Uneven cooling is a common issue in our area, often caused by improper ductwork design, leaking ducts, or an undersized system struggling in our humid summers. At Finley, we perform a detailed airflow and duct assessment to identify restrictions or leaks. Solutions can include duct sealing, rebalancing your system, or installing a zoning system to give you precise control over each area of your home.

Absolutely. Improper sizing—either too large or too small—is a frequent problem we see in St. Louis homes. An oversized system short-cycles, wasting energy and failing to dehumidify, while an undersized one runs non-stop. We conduct a Manual J load calculation, the industry standard, to determine the exact capacity your home needs for efficient and effective comfort.

Our evaluation is a thorough health check for your system. We inspect the entire system—thermostat, air handler, compressor, ductwork, vents, and insulation. We measure airflow, static pressure, and temperature differentials. This allows us to provide a clear, honest assessment of your system's performance and any issues causing uneven temperatures or high bills, along with prioritized repair or replacement options.
