Residential HVAC Questions
How much does a new AC cost in California?
Most central AC installations in the Bay Area and Central Valley run between $4,000 and $12,000, depending on system size, efficiency rating, and brand. We provide a free, itemized estimate so you know exactly what you're paying for.
How often should I service my AC?
At least once a year, ideally in spring before the summer heat. Annual maintenance keeps your system efficient, prevents breakdowns, and protects your manufacturer warranty.
Do you offer emergency AC repair?
Yes 24/7. If your AC fails during a heat wave, call 408-841-4588 and we'll dispatch the nearest technician as fast as possible.
What brands do you service?
Carrier, Trane, Lennox, Rheem, Goodman, Daikin, Mitsubishi Electric, Bosch, and more. Our technicians are factory-trained on all major residential brands.
How long does an AC installation take?
A standard central AC replacement typically takes one day. Full system installations with new ductwork may take two to three days. We'll give you a clear timeline before we start.
Do you handle permits and inspections?
Yes. We pull all required permits and schedule final inspections for installations across San Jose, Sacramento, Modesto, and surrounding cities, so your new system is fully code-compliant.
What is a SEER rating and why does it matter?
SEER stands for Seasonal Energy Efficiency Ratio, and it measures how efficiently an AC cools. Higher is better, and modern units run 14 to 21 SEER. Swapping an old 10-SEER unit for a high-SEER model can cut your cooling bill by a third, so we size and spec every install to your home.
How do I know if I need duct sealing?
If some rooms are always hot or cold, your energy bills keep climbing, or dust builds up faster than normal, your ducts are probably leaking. We test airflow, find the leaks, and seal them with Aeroseal or mastic to stop the waste.
Do you offer financing for furnace replacement?
Yes. We offer 0% APR financing on qualifying furnace replacements, and we help you claim California utility rebates and federal tax credits on high-efficiency models so a new furnace fits your monthly budget.
Are you licensed to work in Sacramento County?
Yes, we are fully licensed and insured to perform HVAC work across Sacramento County and the surrounding area, and we pull all required permits for installations so your job stays code-compliant and worry-free.
How fast can you arrive for an emergency?
For true emergencies, we target 60 minutes in the Bay Area, 90 minutes in Sacramento, and 2 hours in Modesto and the Central Valley. Call 408-841-4588 and we will dispatch the nearest available technician.
