HVAC Repair Denton TX | Call Strittmatter Air Conditioning

Common signs include reduced cooling capacity (your home never feels cool enough), longer run times, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound near the indoor unit. If you suspect a leak, it's important to call for service promptly, as low refrigerant strains the compressor and leads to higher energy bills.

Erratic cooling or heating is often due to faulty thermostat wiring, which is a common issue in older Denton homes. Loose, corroded, or incorrectly connected wires can send the wrong signals to your HVAC system. Our technicians perform thorough wiring diagnostics to identify the fault—whether at the thermostat, in the wall, or at the system control board—and make secure, code-compliant repairs to restore proper communication and control.

Our preventative maintenance service is designed for North Texas conditions. We check refrigerant levels to catch small leaks early, inspect and tighten all electrical connections (including thermostat wiring) to prevent future faults, clean coils to maintain efficiency, and ensure all components are in top shape. This proactive care helps prevent the most common breakdowns, extends system life, and keeps your energy costs in check through our hot summers.
