The most frequent sign we see in San Leandro homes is your AC running constantly but not cooling effectively. You might also notice higher-than-normal energy bills or ice forming on the refrigerant lines or evaporator coil.

Absolutely, and it's a smart move for San Leandro homeowners looking to maximize their solar investment. However, proper integration is key.

We handle the electrical compatibility and can even help configure smart thermostats to prioritize solar-powered operation, helping you slash grid energy use and get the most from your renewable power.

Simply adding refrigerant without fixing the leak is illegal, wasteful, and ineffective. EPA regulations require the leak to be repaired first. More importantly, a leak means there's a flaw in the system—often due to vibration, corrosion, or faulty joints common in our area. At Big Cities Mechanical, we locate and seal the leak, then perform a vacuum test to ensure the system is airtight before recharging it with the precise amount of refrigerant. This corrects the root cause, restores efficiency, and prevents further damage to your compressor.
