Dog Gone Cool Heating & Air Conditioning: Trusted HVAC Repair Serving Jacksonville 75766

In our Jacksonville climate, evaporator coils often freeze due to restricted airflow (like from a dirty filter), low refrigerant levels, or a malfunctioning blower fan. This ice buildup reduces cooling and can damage the compressor. Dog Gone Cool's technicians quickly diagnose the root cause—whether it's a simple filter change or a refrigerant leak repair—to restore efficient operation and prevent further issues.

A faulty reversing valve, crucial for switching between heating and cooling, often shows as the system blowing cool air in heat mode or warm air in cool mode, or getting stuck in one mode entirely. Given the workload of East Texas heat pumps, valve failure is a common local repair. We'll test the valve and electrical controls to determine if a repair or replacement is needed to restore your home's proper temperature control.

Absolutely. Many coil freeze-ups and valve issues start with minor, preventable problems like dirt buildup, wear, or refrigerant issues. Our Jacksonville-focused maintenance service includes coil cleaning, system pressure checks, component inspection, and filter changes. This proactive care helps your HVAC system handle our local temperature swings efficiently, reducing emergency breakdowns and extending your unit's lifespan.
