Gibbs Heating and Air Conditioning provides complete AC replacement with small-team assessments that ensure your new system is properly sized and installed for long-term performance.

Each installation is completed with full system testing and clear guidance on how to use and maintain your new equipment.

Plan your replacement before the high-demand summer months to ensure availability and avoid last-minute disruptions in Mill Valley.

Details That Matter Most

Replacement begins with an in-home assessment where we evaluate your current system, measure your home's cooling load, and discuss your comfort priorities. Proper sizing is critical to ensuring your new AC doesn't overwork or underperform. In Mill Valley, where home styles range from single-level ranches to hillside multi-stories, getting the sizing right is essential for balanced cooling and energy efficiency.

Gibbs Heating and Air Conditioning removes your old unit, installs the new system, and connects it to your existing ductwork or makes modifications as needed. We test airflow, refrigerant charge, and thermostat function before we leave. Your new system is ready to deliver reliable cooling from day one.

We also provide recommendations on maintenance schedules and filter changes to help you get the most out of your investment. Replacements are available throughout Mill Valley and nearby towns, and we encourage homeowners to schedule early to avoid peak-season delays.

What to Expect When You Book

Homeowners often ask how to choose the right system, what the installation timeline looks like, and whether their ductwork needs updating before replacement.

How do I know what size AC system I need?
We perform a load calculation based on your home's square footage, insulation, window placement, and layout. Proper sizing prevents short cycling and ensures even cooling throughout your space.
How long does AC replacement take?
Most replacements are completed in one day. If ductwork modifications or electrical upgrades are needed, the timeline may extend to two days.
Can I replace my AC without replacing my furnace?
Yes, as long as your furnace is in good condition and compatible with the new AC system. We'll evaluate both and let you know if any adjustments are needed.
Will a new AC system lower my energy bills?
Modern systems are significantly more efficient than older models, especially if your current unit is over 10 years old. You'll likely see a noticeable reduction in cooling costs during the summer months in Mill Valley.
Do you handle permit requirements for AC replacement?
Yes. We manage all local code and permit requirements to ensure your installation meets safety and compliance standards.

Replacing your AC system improves comfort, reduces energy waste, and provides peace of mind through the warmest months of the year. Contact Gibbs Heating and Air Conditioning to schedule your air conditioning replacement in Mill Valley and start planning your upgrade today.
