Get answers to common questions about hvac services in Fairfield, California.
For a standard single-family home in Fairfield, a full AC replacement typically ranges from $5,000 to $12,000. The final cost depends heavily on the unit's efficiency (SEER rating), your home's size, and the complexity of the installation. Given our hot, dry summers, investing in a higher-efficiency unit (16 SEER or above) can offer significant long-term savings on Pacific Gas and Electric (PG&E) bills, and you may qualify for rebates.
The absolute best time is during the spring (March-May) or fall (September-November). Scheduling during these mild shoulder seasons ensures your system is serviced and ready for peak summer heat or winter chill, and you'll find greater technician availability and potentially better pricing. Waiting until the first 100-degree day in July often leads to emergency service calls, longer wait times, and higher costs.
Always verify the company holds a valid CSLB license (you can check online) and carries both liability and worker's compensation insurance. Look for established local companies with strong reviews specific to Solano County, as they understand our local climate and water quality issues that can affect systems. Be wary of door-to-door sales or quotes that seem drastically lower than others, as they may cut corners.
It is normal for the system to run longer during extreme heat (common in July/August), but it should still cycle on and off periodically. If it's running non-stop and not cooling your home adequately, it's a sign of a problem. Common local issues include refrigerant leaks, a dirty condenser coil clogged with pollen and dust, or an undersized unit. Prompt service is crucial to prevent a complete breakdown during a heatwave.
