R and K Heating & Cooling | Expert HVAC Services in Greenville, NC

This is a frequent issue in our summer heat. Often, it's due to low refrigerant from a leak, a frozen evaporator coil from a dirty air filter or airflow issue, or a failing compressor. Our technicians perform a thorough diagnostic to pinpoint the exact cause—like checking pressure levels and inspecting coils—and provide a clear, upfront repair plan to restore your cooling quickly.

Uneven cooling is often a sign of ductwork problems or an improperly balanced system. In many Greenville homes, ducts can become leaky, kinked, or poorly insulated, starving some rooms of cool air. It can also be due to a single thermostat struggling to read an accurate average temperature. We perform detailed airflow testing and duct inspections to identify restrictions or leaks and offer solutions like sealing, rebalancing, or adding zoning controls for consistent comfort in every room.

Preventative maintenance is key. We recommend a professional tune-up each spring to clean coils, check refrigerant levels, ensure electrical components are tight, and calibrate your thermostat. This proactive service helps your system run efficiently, prevents minor issues from becoming major breakdowns on the hottest days, and can extend the lifespan of your unit. Simple homeowner steps like changing your air filter monthly also make a big difference.
