Common AC Problems We Fix

Air conditioning systems are precision machines that balance refrigerant pressures, airflow, and electrical controls to cool your home. When any part of that system fails, cooling suffers. Here are the most common AC problems San Francisco homeowners call us about:

• AC not cooling — Your system runs but the air coming from the vents isn't cold. This is the most common AC complaint and can stem from low refrigerant due to a leak, a dirty or failing evaporator coil, a malfunctioning compressor, or a bad expansion valve. Sometimes the outdoor condenser unit is clogged with debris and can't reject heat effectively.
• Weak airflow from vents — When you can barely feel air coming from your registers, the problem is often a clogged air filter that hasn't been changed in months. Other causes include a failing blower motor, a loose or damaged blower wheel, collapsed ductwork, or a frozen evaporator coil that's blocking airflow entirely.
• Water leaking from indoor unit — Air conditioners produce condensation as part of the cooling process, and that water is supposed to drain away through a condensate line. When the drain line clogs with algae, dust, or debris, water backs up and leaks onto your floor or into your ceiling. A cracked drain pan can also cause leaks.
• Frozen evaporator coils — Ice forming on your indoor coils is a sign that something is restricting airflow or that refrigerant levels are low. A dirty filter, a failing blower, closed vents, or a refrigerant leak can all cause the evaporator to freeze. Running the system in this state damages the compressor over time.
• Strange smells from the AC — A musty smell usually indicates mold or mildew growth on the evaporator coil or in the ductwork, common in San Francisco's damp climate. A burning or electrical smell suggests an overheating motor or electrical issue. A rotten egg smell from a heat pump system could indicate a dead animal in the ductwork.
• AC won't turn on — When your air conditioner is completely unresponsive, check your thermostat settings and circuit breaker first. If those are fine, the issue may be a blown fuse in the disconnect box, a failed contactor in the outdoor unit, a burned-out compressor, or a tripped safety switch.
• Loud or unusual noises — Grinding sounds often point to a failing compressor or fan motor bearing. Buzzing may indicate an electrical issue or a loose component. Rattling usually means a loose panel, loose hardware, or debris inside the unit. Hissing or bubbling can signal a refrigerant leak.
• Thermostat not responding — If adjusting your thermostat doesn't change what the AC does, the thermostat itself may be faulty, miscalibrated, or improperly wired. On smart thermostats, Wi-Fi connectivity issues or software glitches can also disrupt communication with your AC system.

Our AC Repair Process

PrimoPeak follows a systematic approach to air conditioning repair that ensures accuracy, transparency, and lasting results:

Step 1: Schedule your repair. Call (415) 555-0199 or book online. Describe the symptoms you're experiencing — not cooling, leaking, noisy, or something else — so our technician arrives prepared with the right tools and parts.

Step 2: Full system evaluation. Our technician inspects both the indoor and outdoor components of your AC system. We check refrigerant pressures, measure airflow and supply temperatures, test electrical components, inspect the condensate drainage, and evaluate the condition of coils and filters. This thorough approach ensures we find the real problem, not just the obvious symptom.

Step 3: Honest diagnosis and quote. We explain what we found and present your repair options with clear pricing. You see the cost before we begin. If the repair doesn't make financial sense given the age and condition of your system, we'll tell you directly and discuss alternatives.

Step 4: Professional repair. Once you approve, we complete the repair using quality parts that meet manufacturer specifications. Our technicians are trained on the specific designs and common failure modes of every major AC brand, from Carrier central air systems to Mitsubishi ductless mini-splits.

Step 5: Performance testing. After the repair, we measure supply and return air temperatures, check refrigerant pressures, verify proper drainage, and confirm that the thermostat communicates correctly with the system. We don't leave until your AC is cooling properly.

AC Repair Cost in San Francisco

Air conditioning repair in San Francisco typically costs between $150 and $500, depending on the nature of the problem and the parts required. Here's what you can expect for common repairs:

• Diagnostic fee: $89, waived if you proceed with the repair
• Capacitor replacement: $150–$250
• Refrigerant recharge (with leak check): $200–$450
• Contactor replacement: $150–$250
• Condensate drain cleaning: $100–$175
• Blower motor replacement: $250–$450
• Fan motor replacement (outdoor unit): $200–$400
• Evaporator coil cleaning or replacement: $300–$700
• Compressor replacement: $500–$900+

Note that systems still running R-22 refrigerant (common in units manufactured before 2010) face higher refrigerant costs due to the EPA phase-out. If your system uses R-22 and needs a significant repair, we may recommend upgrading to a newer, more efficient unit that uses R-410A or R-454B refrigerant.

A full AC system replacement in San Francisco ranges from $4,000 to $12,000 or more depending on the system type and size, so a $200–$500 repair on a relatively young system is almost always the more cost-effective path.
