San Diego HVAC Guide
San Diego summers are getting hotter, and when the AC quits in August, you need a technician fast. These 15 HVAC companies handle everything from emergency AC repairs and seasonal tune-ups to furnace troubleshooting, heat-pump installations, and full system replacements across the county.

Quick answer: For same-day AC repair: Mauzy or Anderson. For full system replacement: Carini or Semper Solaris. For mini-splits/heat pumps: West Coast Heating & Air. For heating or furnace repair: Bob Jenson, Air Ace, or Anderson. Emergency service calls run $150–$300; common AC repairs are $150–$1,200, furnace repairs $150–$900, and full replacement $6,000–$15,000 depending on system size and efficiency.
If the system runs but the house stays warm, check the thermostat setting, replace a clogged filter, and look for ice on the indoor coil or a tripped breaker. Stop and call a licensed technician if you smell burning, hear a hard-starting compressor, see refrigerant leaking, or the breaker trips again. A diagnostic visit commonly runs $125–$225 before parts and labor. Ask for the diagnosis in writing and compare the repair price with the unit's age, warranty, and replacement cost before approving a compressor or coil job.
Heating failures are less frequent here than cooling failures, but a cold inland night still makes a broken furnace urgent. Common calls include failed igniters, dirty flame sensors, blower motors, thermostat faults, and duct leaks. Never keep operating a furnace that produces a gas smell, soot, unusual yellow flames, or a carbon-monoxide alarm — leave the home and contact the gas utility or emergency services as appropriate. For a routine furnace visit, ask whether the technician checked combustion, venting, the heat exchanger, and carbon-monoxide levels rather than only resetting the thermostat.
Repair usually makes sense when the equipment is younger, the failure is isolated, and the fix is comfortably below the cost of a new system. Replacement deserves a quote when a system is near the end of its expected life, needs repeated refrigerant or major component work, or cannot cool rooms evenly. Get two or three written proposals that separate equipment, labor, permits, duct changes, warranty, and disposal. For inland homes, compare a high-efficiency AC with a heat pump; coastal homes should also ask about salt-air protection and condenser placement.

Replace filters every 30–90 days. San Diego dust and pollen load is moderate, but coastal salt and inland dust both shorten filter life.
Get annual tune-ups. A spring AC check and fall furnace check catch issues before peak season and keep warranties valid.
Check SEER ratings. Modern systems start at 14 SEER in California; higher SEER costs more upfront but saves on summer bills.
Ask about heat-pump incentives. Federal and state rebates can offset heat-pump and mini-split installation costs significantly.
Don't ignore salt-air corrosion. Coastal condos and homes near the ocean should have condenser coils cleaned annually to prevent corrosion.
Get multiple quotes for replacement. A full AC replacement is a major purchase; quotes from 2–3 contractors often vary by $2,000+.
Verify CSLB license and insurance. California HVAC work requires a licensed contractor (C-20 Warm-Air Heating, Ventilating, and Air-Conditioning).
A standard service call is $125–$225. Common repairs like capacitor or contactor replacement run $150–$300. Fan motor or compressor repairs are $400–$1,200+. Full AC replacement is $6,500–$10,000 for a standard 3–5 ton system.
For emergency service, Mauzy, Anderson, and Bill Howe all offer 24/7 support. For full-system replacement, Carini, Bob Jenson, and Mauzy are solid. For ductless mini-splits and heat pumps, West Coast Heating & Air is a strong choice.
At least once per year, ideally in spring before summer heat. Homes with pets, allergies, or coastal exposure benefit from twice-yearly service.
Yes. Most cities and the county require a permit for AC replacement and any electrical or refrigerant line work. Reputable contractors pull the permit for you and schedule inspections.
California minimum is currently 14 SEER for new systems. In San Diego's mild climate, 14–16 SEER is usually cost-effective. Higher SEER (18+) makes sense if you run AC heavily or want maximum rebates.
Yes. San Diego's mild climate is ideal for heat pumps, which provide efficient heating and cooling. Combined with rebates and rising summer temperatures, heat pumps are increasingly popular.
Common causes include low refrigerant, dirty filter, frozen evaporator coil, faulty capacitor, or blocked condenser. A $125–$225 diagnostic call will pinpoint the issue.
