AC Repair
Our AC repair service addresses refrigerant leaks, compressor failures, thermostat issues, and electrical problems. Using advanced diagnostic tools, we identify root causes and implement lasting solutions. Technicians handle central air, ductless mini-splits, and window units, ensuring efficient cooling during San Jose's hottest months. Regular maintenance reduces breakdown risks and extends system lifespan.
Duct Cleaning
Professional duct cleaning removes dust, debris, and contaminants from residential and commercial HVAC systems. Our process improves indoor air quality, enhances system efficiency, and reduces energy costs. Using industrial vacuums and rotating brushes, we clean all duct sections, with optional sanitization to eliminate odors and microorganisms.
Heating System Replacement
We replace aging heating systems with energy-efficient models from Carrier, Trane, and Lennox. Our process includes system design, proper sizing, and professional installation. New systems lower energy bills, improve temperature control, and enhance safety. We handle permits, old unit removal, and post-installation testing for optimal performance.
