Frequently Asked Questions
Is it worth upgrading my old AC for the new efficiency standards?
The 2026 federal minimum is now 14.3 SEER2, a significant jump from older units often rated at 10 SEER or less. At PG&E's current $0.44 per kWh rate, a modern system can cut cooling costs by nearly half. The active Inflation Reduction Act rebates, with a cap of $8,000, directly offset the premium for high-efficiency models, making the payback period in San Carlos exceptionally short.
My AC just stopped on a hot day. How fast can you get here?
For a no-cool emergency in White Oaks, our dispatch routing from Burton Park via US-101 ensures a technician arrives within 10 to 15 minutes. We prioritize these calls to prevent heat buildup and potential compressor damage. The initial diagnosis often involves checking for a tripped breaker or a clogged condensate safety switch, which are quick first steps upon arrival.
My Ecobee thermostat is showing an E132 alert. What does that mean?
The Ecobee E132 code specifically indicates a loss of communication with the outdoor heat pump unit. In San Carlos, this often points to a condensate drain line blockage triggering a safety float switch, which cuts power to the outdoor unit. It can also signal a failed control board or a wiring issue. This alert allows for targeted diagnostics, preventing a full system failure during critical cooling periods.
Can my current ducts handle a better filter for wildfire smoke and pollen?
Upgrading filtration to MERV-13 is critical for San Carlos's April pollen peak and wildfire PM2.5 risk. Your existing flexible R-6 insulated ducting may not handle the increased static pressure from a dense filter without airflow loss. A technician must measure static pressure to confirm; often, sealing duct leaks is required first to enable effective high-MERV filtration without straining the blower motor.
I have gas heat. Should I consider a heat pump?
Switching from gas heat to a modern heat pump in San Carlos is increasingly advantageous. Our winter lows are mild, well within a heat pump's efficient operating range. Utilizing the heat pump during PG&E's off-peak hours outside of 4 PM to 9 PM avoids the highest electricity rates, and the technology qualifies for the same federal rebates, making it a cost-effective year-round solution.
Why does my AC struggle on the hottest days of the year?
San Carlos systems are engineered for a peak load at 85°F outdoor design temperature. When temperatures exceed this, the system's capacity drops. The newer R-454B refrigerant standard for 2026 helps by maintaining better pressure-temperature relationships and efficiency in these high-heat scenarios compared to older R-410A, but no system can overcome a design limit it wasn't sized for.
What should I know about permits and safety for a new AC install?
All HVAC replacements in San Carlos require a permit from the City of San Carlos Building Division. Since 2026, new systems use mildly flammable A2L refrigerants like R-454B. The permit process now includes verification of mandated safety features: leak detectors, updated electrical disconnects, and proper equipment room ventilation. This ensures the installation meets current California building and fire codes for your safety.
My system is original to the house. Should I expect problems?
Systems from the average 1961 San Carlos build year are now 65 years old, which exceeds the typical 15-20 year service life. In White Oaks, this age makes the flexible R-6 ducting and internal components highly susceptible to the common condensate drain line biofilm blockage. Older PVC drain lines develop a slimy microbial layer from constant use, which can cause water backup and system shutdowns, especially during our humid spring periods.
