Best HVAC Services in San Diego, CA 92128 - Ninin A/C Supply

Short-cycling is a common issue here, often caused by refrigerant leaks, a dirty evaporator coil, or an oversized unit. Our expert technicians will diagnose the root cause. In many cases, a repair like sealing a leak or cleaning components resolves it. We only recommend a replacement if the system is inefficient or beyond repair, ensuring you get the right, cost-effective solution for your home.

Signs of a leak include reduced cooling, hissing sounds, ice on the refrigerant lines, and higher energy bills. Our repair process starts with a precise leak detection test using specialized tools. Once located, we repair the leak, evacuate the system to remove moisture and air, and then recharge it with the correct amount of refrigerant. This restores efficiency and cooling power, which is crucial for our San Diego summers.

For our coastal climate with mild winters and dry summers, we recommend a high-efficiency heat pump or an AC with a compatible furnace. Proper sizing is critical—an oversized unit will short-cycle. We perform a detailed load calculation for your home to ensure the new system is perfectly sized for efficiency and comfort, helping you save on energy bills while providing reliable temperature control.
