The Low-Bid Temptation
HVAC quotes can vary by 50% or more. The lowest bid is tempting, but it usually reflects corners being cut somewhere.
Improper Sizing
Cheap installers skip Manual J calculations. Oversized equipment short-cycles, wastes energy, and wears out faster. Undersized equipment never reaches comfort goals.
Poor Ductwork Connection
Leaky, kinked, or improperly connected ductwork wastes 25-40% of conditioned air. Quality installation includes duct testing and sealing.
Skipped Electrical Work
Undersized wiring, improper disconnects, and code violations create safety hazards and may void warranties.
Voided Warranties
Most manufacturers require certified installation for warranty coverage. Unlicensed installers may void your 10-year compressor warranty.
Reduced Equipment Life
Poor installation causes premature wear. Equipment that should last 20 years may fail in 10, costing you another replacement.
