Get answers to common questions about hvac services in Aliso Viejo, California.
For a standard single-family home in Aliso Viejo, a full AC replacement typically ranges from $5,000 to $12,000. This cost is influenced by the system's size (measured in tons), the SEER (Seasonal Energy Efficiency Ratio) rating, and the complexity of the installation. Given our hot, dry summers, investing in a higher SEER unit (like 16+) can offer significant long-term savings on electricity bills, and you may qualify for state or utility rebates from providers like Southern California Edison.
The optimal time is during the mild spring (March-May) or fall (September-November) seasons. Scheduling service during these shoulder seasons ensures your system is fully tuned up before the peak summer heat arrives, and you'll find greater technician availability and potentially better pricing. Waiting until the first major heatwave in June or July often leads to emergency service calls, longer wait times, and higher costs.
Yes, California has strict regulations. Most notably, for replacements, you must hire a licensed contractor who will pull a permit with the City of Aliso Viejo Building Division. Furthermore, state law requires a Title 24 energy calculation (a Manual J load calculation) to ensure your new system is correctly sized. Also, as of 2023, California has begun phasing out high-GWP refrigerants, so your new system will likely use a more environmentally friendly refrigerant like R-410A or the newer R-454B.
Always verify the contractor holds a valid California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license and carries both liability and worker's compensation insurance. Look for companies with strong local reviews and a long-standing presence in South Orange County, as they understand our specific microclimate and common home styles. A trustworthy provider will perform a detailed home assessment and provide a written, itemized quote—not just a phone estimate.
It is common for systems to run more frequently during peak afternoon heat, especially in older homes with standard insulation. However, if it's running non-stop for hours without adequately cooling your home, it indicates an issue. Common local causes include an undersized unit, refrigerant leaks, dirty coils from our dusty Santa Ana winds, or inadequate attic insulation. A professional evaluation can determine if repair, maintenance, or an upgrade is needed to improve efficiency.
