What we do
From a failed capacitor to a full system replacement, San Diego HVAC pros handle it all — AC, heating, air quality, residential and commercial.
Heating problems get worse when ignored — a dirty flame sensor becomes a dead furnace at 2 AM. Our San Diego furnace repair crews handle gas, electric, and oil systems with same-day service when it counts. Call (877) 317-0473.
Leaky, dirty ducts can waste 20–30% of your heating and cooling. Our San Diego duct cleaning crews clean supply and return runs, then flag leaks and insulation gaps worth fixing — because clean ducts attached to leaky ones only go so far.
No cooling in a heat wave or no heat in a freeze is an emergency — full stop. Our San Diego emergency HVAC line is answered 24/7, with techs dispatched around the clock for no-heat and no-cool calls.
Dust, allergens, wildfire smoke, pet dander — San Diego indoor air carries more than you think. We assess your home's air and install the right combination: high-MERV filtration, UV treatment, humidifiers, and dehumidifiers matched to your system.
A new AC is a 12–15 year decision. Our San Diego installation crews size by Manual J calculation, not rule of thumb, and set up airflow and charge correctly — the details that separate a system that lasts from one that limps.
Not every warm-air complaint needs a new system. Our San Diego AC repair techs test first — electrical, refrigerant charge, airflow, thermostat — and repair only what is actually failing. Free quote before any work begins.
From small offices to multi-unit properties, San Diego businesses get the same discipline: documented service, written scopes, and scheduling that works around your hours — not ours. Reach us at (877) 317-0473.
An energy audit in San Diego ends with a prioritized action list — the fixes that pay back fastest, in order. No upsell, just measured findings: leaky ducts, poor insulation, oversized equipment, bad airflow. Call (877) 317-0473 to schedule.

SEER2 is the seasonal cooling-efficiency rating — higher means cheaper to run. Current DOE minimums are 14.3 SEER2 in this region. Upgrading from an old 10-SEER unit to a 16-SEER2 system can cut cooling costs noticeably. Call (877) 317-0473 to compare options for your San Diego home. Your free quote includes documented findings on everything we check.
Typically 12–15 years for central AC, 15–20 for furnaces, with maintenance being the biggest variable. San Diego's climate works systems hard, so twice-yearly tune-ups pay off. Call (877) 317-0473 for a free system checkup. We will put the full scope in writing before work begins.
Older systems use R-410A, which manufacturers are phasing down in favor of R-454B and R-32 — and 2026 refrigerant prices are climbing. If your San Diego system needs frequent recharges, a leak repair or a matched-system replacement may beat endless top-offs. Call (877) 317-0473 for an honest assessment. Evening and weekend appointments are available across San Diego.
In 2026, installed central AC in San Diego typically runs $3,500–$12,000 depending on size, efficiency, and ductwork. A proper load calculation — not the old unit's nameplate — determines the right size. Free quotes at (877) 317-0473. Ask about current scheduling when you call (877) 317-0473.
Twice a year: AC tune-up in spring, furnace tune-up in fall. Regular service catches worn parts early, keeps efficiency up, and prevents most mid-season breakdowns. Maintenance visits run $80–$200 in San Diego — schedule at (877) 317-0473. Ask about current scheduling when you call (877) 317-0473.
Usually a dirty flame sensor, a failed igniter, or a tripped safety switch — all fixable. Do not keep resetting it repeatedly; if it will not stay lit after one reset, call (877) 317-0473 for same-day San Diego furnace repair. There is no obligation; the findings are yours to keep.
