AC sizing depends on multiple factors: square footage, ceiling height, insulation quality, window count/orientation, and local climate conditions. In Lodi's climate zone, we typically see homes requiring 1 ton of cooling per 400-600 square feet. However, older homes may need larger units due to less insulation. We perform detailed load calculations using Manual J methodology to ensure proper sizing - oversized units waste energy and undersized units can't maintain comfort.

Key strategies include upgrading to a high-SEER AC unit, sealing ductwork (we find 20-30% efficiency gains from duct sealing in older Lodi homes), improving insulation, installing programmable thermostats, and regular maintenance. Consider zoning systems for multi-story homes common in Lodi. We also recommend whole-house energy audits to identify the most cost-effective improvements for your specific home.

Our installation process includes: in-home consultation and load calculation, equipment selection and permitting (when required by Lodi regulations), removal of old equipment, installation of new indoor and outdoor units, electrical connections, refrigerant lines, condensate drainage, system testing, and customer education. Most residential installations complete in 1-2 days. We handle all permits and ensure compliance with local codes and manufacturer specifications for warranty protection.
