Frequently Asked Questions About Installation in San Diego

How long does a full system install take?
Most residential projects wrap up within a single day. Larger homes, multi-zone systems, or jobs requiring ductwork modifications may run into a second day. The timeline is confirmed before work begins.
Can I replace just the outdoor unit?
In some situations, yes — but it carries real risk. Mismatched components reduce efficiency, can void manufacturer warranties, and often lead to additional system failures. We assess the full setup before recommending partial or complete replacement.
Do I need new ductwork with a new cooling system?
Not automatically. We inspect existing ductwork during the assessment. Ducts in good condition are reused with the new system. Significant leakage or damage may require targeted work on the affected sections.
What size system do I need for my home?
Size depends on square footage, insulation, ceiling height, window count, and local climate. An oversized unit short-cycles, wastes energy, and wears out faster. The Manual J calculation from the free estimate determines the correct tonnage for your home.
Should I replace a unit that's 10 years old?
It depends on service history, performance, and refrigerant type. A 10-year-old air conditioner with minimal service may have years left. A unit with repeated service calls, declining output, or discontinued R-22 refrigerant is a strong replacement candidate regardless of age.
What is the most energy-efficient system available today?
Inverter-driven heat pumps with SEER2 18+ ratings are the most efficient option available. These units operate on next-generation refrigerants like R-454B — far lower global warming potential than R-410A. R-22 (Freon) was phased out in 2020 and cannot be legally recharged; any system still running on it should be replaced promptly.
