AC Installation for Lake San Marcos homes, done by vetted San Diego County technicians. A useful AC quote identifies the exact indoor and outdoor equipment, explains how capacity was selected, and states what happens with ducts, wiring, line sets, drainage, permits, testing, and old-equipment removal. The matched company should confirm which local requirements apply to the address and scope.
Inland heat loads need a real Manual J, not a rule of thumb. A system that fits Encinitas will not automatically fit San Marcos. The matched company sizes for that house's hottest afternoon, not an average.

Quoted after assessment; equipment, capacity, efficiency, ducts, electrical work, access, permits, and controls affect price. That's the same approach across San Diego County, and the contractor confirms the number for Lake San Marcos before any work starts.
Lake San Marcos is a private golf community with a heavy retiree demographic, original HVAC systems are well past their replacement window, and heat pump conversion with smart-thermostat integration is the dominant upgrade path. HOA architectural standards require coordination on visible equipment placement. Inland heat loads need a real Manual J, not a rule of thumb.
Compare model numbers, matched-system ratings, sizing method, duct and electrical allowances, line-set and drain work, permit responsibility, commissioning, removal, payment schedule, exclusions, and separate labor and parts warranty terms.
Ask how the contractor evaluated the home load, including insulation, windows, orientation, air leakage, occupancy, and ducts. The company should explain the calculation and any assumptions instead of relying only on floor area.
