TopNotch Heating & Air | Best HVAC Services in North Augusta, SC

In our hot, humid climate, the most common culprits are often simple. We first check for a dirty air filter, which severely restricts airflow, and then inspect the outdoor condenser unit for debris like grass clippings or leaves. Low refrigerant levels due to a leak are another frequent issue we diagnose. Our thorough inspection aims to identify and resolve the problem quickly to restore your comfort.

We recommend professional maintenance twice a year—once in the spring for your cooling system and once in the fall for your heating system. This proactive schedule is crucial in our area to catch minor issues before they become major repairs, ensure peak efficiency for our seasonal temperature swings, and extend the overall lifespan of your equipment.

A faulty reversing valve, which switches your system between heating and cooling, often shows itself as the system getting 'stuck' in one mode. You might have the thermostat set to cool, but only warm air comes out, or vice versa. You may also hear a faint hissing noise. As local specialists familiar with this common issue, we can accurately diagnose and replace the valve to restore your system's proper function.
