AC Repair
Our NATE-certified technicians handle all AC repair needs, from minor fixes to major system restoration. We diagnose issues like refrigerant leaks, electrical failures, and compressor problems while maintaining strict cleanliness standards during service. With 24/7 emergency availability and upfront pricing estimates, we ensure rapid restoration of cooling systems during San Diego's extreme heat. Our repairs come with a 100% satisfaction guarantee and include thorough post-service verification.
Ductless Mini-Split
We specialize in ductless mini-split systems for homes without existing ductwork. Our experts calculate precise BTU requirements for each zone and perform clean installations with minimal home disruption. Services include wall-mounted unit installation, refrigerant line routing, and smart thermostat integration. Systems offer zoned temperature control and energy efficiency benefits, with financing options available for qualified customers seeking modern cooling solutions.
Indoor Air Quality
Our IAQ specialists address allergens, mold, and pollutants through advanced filtration and UV purification systems. We conduct comprehensive home assessments to identify contamination sources, then implement solutions like high-MERV filters and UV germicidal lights. The Phenomenal Aire system reduces particulates through ionization technology without ozone production, creating healthier living environments while improving HVAC system efficiency.
Heater Installation
We provide energy-efficient furnace installations with SEER-rated equipment and precise sizing calculations. Our process includes load calculations to prevent undersized or oversized systems, ensuring optimal performance and longevity. All installations meet local code requirements with lifetime workmanship guarantees. We offer free consultations to evaluate replacement needs based on system age, repair frequency, and energy consumption patterns.
Air Duct Repair
Our certified technicians inspect and repair ductwork for leaks, punctures, and mold contamination. We use metal Y-branches and airflow dampers for improved distribution and offer eco-performance duct options. Services address common issues like uneven cooling, high energy bills, and poor airflow while maintaining clean work environments with shoe covers and drop cloths during all service visits.
