Get answers to common questions about hvac services in Washington, California.
In Washington, CA, a full central AC replacement typically ranges from $5,000 to $12,000. Key factors include the system's size (tonnage) needed for our hot Central Valley summers, the efficiency rating (SEER), and the complexity of the installation with your existing ductwork. Local regulations, like California's Title 24 energy standards, also mandate high-efficiency units, which can increase upfront cost but offer long-term savings and potential rebates.
The optimal time is during the mild spring (March-May) or fall (September-October) seasons. Scheduling service before the intense summer heat, which regularly exceeds 100°F, ensures your system is reliable when you need it most and helps avoid the peak demand rush. This timing also provides better availability for contractors and can sometimes lead to promotional pricing outside the peak season.
Yes, California has strict regulations that directly impact HVAC installations. Most notably, Title 24 mandates minimum efficiency standards (currently 15 SEER for ACs), and you may need a permit from the City of Washington or Yolo County. Furthermore, for furnaces, California law requires they be ultra-low NOx models to reduce air pollution, which is a critical consideration in the Central Valley.
Always verify the contractor holds a valid California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license with the CSLB and carries proper insurance. Look for local companies with strong reviews and deep experience with the specific demands of our climate, such as managing hard water scale in units and designing systems for extreme heat. Getting multiple detailed estimates is also highly recommended.
During extended heatwaves with temperatures over 105°F, it is normal for your system to run in longer cycles to maintain your set temperature. However, you should be concerned if it never shuts off, fails to cool the house adequately, or causes a significant spike in your PG&E bill. This could indicate an undersized unit, refrigerant issues, or poor insulation—all common concerns in our region that require professional diagnosis.
