HVAC Services Fountain Valley CA | Call Maxtec Heating & Air Conditioning Service

A sudden drop in cooling power is a common sign of a refrigerant leak. First, check your air filter and ensure vents are open. If the issue persists, turn off the system to prevent compressor damage and call Maxtec. Our technicians use electronic leak detectors to find the exact source, even in hard-to-reach spots, and we repair the leak before recharging the system to the manufacturer's exact specification, ensuring efficient operation for your Fountain Valley home.

Thermostat connectivity problems in Fountain Valley often stem from a few key issues: a faulty common 'C' wire providing inconsistent power, compatibility issues between older HVAC equipment and new smart thermostats, or Wi-Fi signal interference. At Maxtec, we diagnose the root cause by checking your wiring, system compatibility, and even your home's network setup. We'll ensure your thermostat has stable power and communicates flawlessly with your HVAC equipment for reliable comfort control.

A professional repair for an AC refrigerant leak is a multi-step process to ensure safety and longevity. Our Maxtec technicians will first recover any remaining refrigerant according to EPA regulations. Then, we use specialized tools to locate the precise leak—often in coils, joints, or valves. After repairing the leak with brazing or component replacement, we perform a pressure test to confirm the seal is perfect. Finally, we evacuate the system to remove moisture and air before recharging it with the exact amount of refrigerant specified for your unit, restoring optimal efficiency and cooling to your home.
