Get answers to common questions about hvac services in Cotati, California.
For a standard single-family home in Cotati, a full AC replacement typically ranges from $5,000 to $12,000. This cost is influenced by the system's size (tonnage), efficiency rating (SEER2), and the complexity of the installation, such as ductwork modifications. Given California's Title 24 energy regulations, investing in a higher SEER2 unit (16+) is often recommended for long-term savings, despite a higher upfront cost, due to our hot, dry summers.
The ideal times are during the mild shoulder seasons of spring (March-May) and fall (September-November). Scheduling service in spring ensures your AC is ready for Cotati's summer heatwaves, while fall service prepares your heating system for cool nights and occasional winter frost. This timing avoids the peak summer rush, leading to better availability and potential off-season promotions from local contractors.
Yes, most significant HVAC installations, like replacing a furnace or air conditioner, require a permit from the City of Cotati or Sonoma County Building Division. This ensures the work complies with California's strict mechanical, electrical, and energy codes (Title 24). A reputable local HVAC contractor will typically pull these permits on your behalf, which is a key sign of a professional and compliant installation.
Prioritize contractors who are locally established, licensed (California CSLB C-20 license), insured, and familiar with Cotati's specific climate and housing styles. Check for strong reviews and ask for references from recent installations in Sonoma County. A trustworthy provider will perform a detailed load calculation (Manual J) for your home, not just size by square footage, to ensure optimal system performance and efficiency.
This is a common concern. Standard air-source heat pumps can lose efficiency when temperatures drop near or below freezing, which occurs on clear winter nights in Cotati. Options include installing a newer cold-climate heat pump model designed for lower temperatures or adding a hybrid system with a gas furnace (dual-fuel) for supplemental heat during the coldest periods. A local technician can assess your specific system and home insulation.
