Custom Air - Memphis's Expert HVAC Services

An improperly sized unit is a common issue here. One that's too small runs constantly, struggling to keep up, while an oversized unit 'short cycles'—turning on and off rapidly. Both waste energy, cause uneven temperatures, and wear out your system fast. At Custom Air, we perform a Manual J load calculation, the industry standard, to determine the exact capacity your home needs. This ensures your new system runs efficiently, providing consistent comfort and lower utility bills.

Yes, that's classic short cycling, and it's hard on your compressor and your wallet. In Memphis, this is often caused by an oversized unit, a refrigerant issue, or a faulty sensor. Our technicians will diagnose the exact cause. Often, the permanent solution is replacing an incorrectly sized system with one we've precisely calculated for your home's layout, insulation, and windows. We fix the symptom and the root problem for long-term reliability.

For us, proper installation starts long before we bring in the new equipment. It begins with a thorough assessment of your home's unique characteristics and a precise sizing calculation. On installation day, our certified technicians ensure perfect airflow, correct refrigerant charge, secure electrical connections, and a clean, sealed duct system. We don't cut corners, because a meticulous installation is what guarantees efficiency, prevents short cycling, and delivers the comfort and savings you expect for years to come.
