HVAC Repair FAQs in Castro Valley, CA

We strongly advise against it. Handling refrigerants requires EPA certification, and overcharging your system can cause catastrophic compressor failure. Professional leak detection and recharging is the safest method.
Water pooling around the indoor unit is a strong indicator that your condensate drain line is clogged or the drain pan is cracked. We can resolve this quickly for homes in Castro Valley, CA by clearing the line and ensuring proper drainage to prevent water damage.
Our experts are highly trained to service and install every major brand, including Carrier, Trane, Lennox, Goodman, and Rheem. We have the parts and experience for standard AC units, gas furnaces, and heat pumps.
If your system is relatively new and the issue is minor—such as a bad capacitor or contactor—repairing is highly cost-effective. However, if the unit is over 10-15 years old, uses outdated R-22 refrigerant, or requires frequent expensive repairs, replacement is your best option.
A well-maintained air conditioning unit typically lasts 10 to 15 years, while a gas furnace can last 15 to 20 years. Regular annual tune-ups are key to maximizing the lifespan of your equipment.
