Everything You Need to Know

Why is my AC blowing warm air?

Warm air from your AC can indicate a few issues: a dirty air filter blocking airflow, low refrigerant levels (which may suggest a leak), or a failing compressor. In San Jose's summer heat, it's best to shut the system off to prevent further damage and call for a professional diagnostic.

How much does HVAC replacement cost in San Jose?

Replacement costs vary widely based on the system size, efficiency rating (SEER2), and if ductwork modifications are needed. A standard AC and furnace replacement in the South Bay typically ranges from $8,000 to $15,000+. We offer free estimates to give you exact pricing for your specific home layout.

Are heat pumps efficient in California?

Yes, heat pumps are incredibly efficient in the Bay Area's moderate climate. Because they move ambient heat rather than generating it from combustion, they can be over 300% efficient. They also help homeowners transition away from gas, aligning with California's clean energy goals while often qualifying for local and state rebates.

Why are my PG&E bills so high in the summer?

High summer energy bills are often caused by an aging, inefficient AC unit or poor duct insulation. Upgrading to a variable-speed compressor or a higher SEER2 rated system can significantly reduce your cooling costs compared to single-stage units built 15 years ago.

How often should HVAC systems be serviced?

We recommend bi-annual service: an AC tune-up in the spring before the hot San Jose summers, and a furnace safety check in the fall. Regular maintenance prevents unexpected breakdowns and keeps the system running at peak efficiency.

What is SEER2 and does it matter for San Jose homes?

SEER2 is the new efficiency standard for air conditioners. Higher ratings mean better efficiency. In the South Bay, where we have high electricity rates, a SEER2 rating of 16+ can pay for itself through energy savings within a few seasons.

Do you offer emergency HVAC repair on weekends?

Yes, we provide 24/7 emergency service throughout San Jose and the South Bay. We know that AC failure during a Silicon Valley heatwave is more than an inconvenience—it's a safety issue. Call us directly for immediate dispatch.
