Licensed HVAC Repair in Concord, NC 28027 - D&D Heating And Cooling

This is a common issue here in Concord, especially during peak summer. Often, the culprit is a dirty evaporator coil, which restricts airflow and prevents proper cooling. It can also be caused by low refrigerant levels, a faulty compressor, or a clogged air filter. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause and explain your repair options clearly.

We recommend a professional tune-up twice a year—once in the spring for your cooling system and once in the fall for your heater. Concord's hot, humid summers and variable winters put extra strain on HVAC systems. Regular maintenance cleans critical components like the evaporator coil, checks refrigerant levels, and ensures efficient operation, helping prevent costly breakdowns when you need your system most.

Absolutely. A dirty coil makes your air conditioner work much harder to remove heat and humidity from your home. This forces the system to run longer cycles, consuming significantly more electricity. Keeping your evaporator coil clean through regular maintenance is one of the most effective ways for Concord homeowners to maintain cooling efficiency and control summer energy costs.
