HVAC Repair Grand Prairie TX | Call Sanchez Service HVAC

A professional installation by our team ensures all connections in your new system are properly sealed and torqued to manufacturer specifications. This critical step significantly reduces the risk of the vibration-induced leaks common in our area. We also perform a thorough pressure test to confirm system integrity before charging it with the correct refrigerant type and amount for optimal, leak-free performance.

Reduced cooling capacity is a classic sign of a refrigerant leak, a frequent issue here. We start with electronic leak detection to pinpoint the exact location—whether in the coil, line set, or connections. Our repair involves sealing the leak, replacing the faulty component if necessary, and then evacuating and recharging the system to the precise level. This restores full cooling power and efficiency to your home.

Absolutely. During a maintenance visit, we don't just clean the physical system; we check the control wiring and voltage at the thermostat terminal. Many connectivity issues stem from faulty wiring or power interruptions at the HVAC unit itself. We ensure the system provides a stable base signal, update firmware if applicable, and help reconfigure your thermostat's Wi-Fi connection for reliable, remote control from your phone.
