HVAC Services Tulsa OK | Call Combs Heating & Air Conditioning

This is a common issue in our area, often caused by Wi-Fi signal interference, outdated firmware, or incorrect wiring during installation. Our technicians can diagnose the specific problem, which may involve reconfiguring your home network settings for the thermostat, performing a firmware update, or ensuring all connections are secure and compatible with your specific HVAC equipment.

Listen for unusual squealing or grinding noises from your air handler, weak airflow from your vents, or your system frequently overheating and shutting off. A failing blower motor puts extra strain on your entire system. We recommend addressing it immediately to prevent a complete breakdown, especially before extreme Tulsa weather hits. We can often repair the motor, but if a replacement is needed, we use durable, OEM-quality parts.

Absolutely. This 'no communication' problem is a frequent service call. Our process involves checking the thermostat's power (often a C-wire issue), testing the control board in your furnace or air handler, and verifying all system compatibility. We'll troubleshoot the entire control circuit to pinpoint whether the issue is with the thermostat itself, the wiring, or your HVAC unit, and provide a clear, fixed-price solution to restore control.
