Installed a Lennox variable-speed heat pump system (model EL20XCV with variable-speed air handler) in a 3,200 sq ft custom home in Ruby Hill, Pleasanton. The new 20 SEER2 system replaced an aging 14 SEER AC and gas furnace, providing whisper-quiet operation, precise humidity control, and reducing energy costs by approximately 45%. The homeowner qualified for $2,400 in combined Bay Area rebates and federal tax credits.
Replaced a 16-year-old 13 SEER AC with a high-efficiency 18 SEER2 Carrier variable-speed heat pump in a 2,400 sq ft Mohr Park home. The old system struggled during Pleasanton's hottest summer days. The new heat pump maintains consistent 72°F comfort even during 95°F heat waves while reducing cooling costs by 38% and providing efficient heating during winter.
Installed a Mitsubishi ductless multi-zone system (model MXZ-4C36 with 4 zones) for a renovated historic home near downtown Pleasanton.
