S & D Heating And Air Conditioning | Best HVAC Services in Gaffney, SC

Common signs include the system blowing cold air in heating mode (or warm air in cooling mode), unusual hissing noises, or the unit struggling to reach the set temperature. Our Gaffney-based technicians are experts in diagnosing reversing valve issues. We'll perform a thorough inspection, check refrigerant pressures, and test the valve's electrical components. If repair or replacement is needed, we use high-quality parts and ensure your heat pump is restored to proper, efficient operation for our local climate.

For most Gaffney homes, we recommend checking your air filter every month and replacing standard 1-inch filters every 1-3 months. Factors like local pollen seasons, pets, or construction can require more frequent changes. A clogged filter restricts airflow, forcing your system to work harder, increasing energy bills, and potentially causing damage. As part of our maintenance services, we can advise on the best filter for your home and help establish a replacement schedule to keep your system running smoothly.

Absolutely. Our preventative maintenance service is designed specifically to catch and resolve common local issues before they lead to a breakdown. During a tune-up, we clean components, check refrigerant levels, inspect electrical connections, test the reversing valve operation, and ensure your system is free of airflow obstructions. This proactive care improves efficiency, extends the life of your equipment, and helps you avoid the discomfort and cost of unexpected repairs, especially during our peak heating and cooling seasons.
