All Points Air Conditioning & Heating inc - Deer Park's Top-Rated HVAC Repair

This is a common issue during our extreme Texas heat. Often, it's caused by a safety overload in the system due to dirty coils, low refrigerant, or a failing capacitor. The unit works overtime to cool your home and eventually shuts down to prevent damage. Our technicians can quickly diagnose the root cause—whether it's a simple cleaning, a recharge, or a part replacement—to get your AC running reliably again.

Absolutely. Incorrect or loose wiring at the thermostat is a frequent culprit for a non-responsive heating or cooling system in Deer Park homes. It can prevent the signal from reaching your AC or furnace. Our experts will carefully inspect the wiring connections, ensure compatibility with your system, and make any necessary repairs or corrections to restore proper communication and operation.

First, check the basics a neighbor might suggest: ensure the thermostat display is on (some have an on/off switch) and confirm the circuit breaker for your HVAC system hasn't tripped. If those are fine, the issue could be dead batteries in the thermostat itself or, more likely, a wiring problem that's cutting power. For persistent blank screens or unresponsiveness, it's best to call us. We can safely troubleshoot the wiring at the thermostat and the unit to find and fix the electrical fault.
