Air Conditioning (AC) Maintenance and Sutton MA’s Trusted Heating & Cooling Professionals — Your Local Experts

SumZero Energy Systems delivers proactive AC maintenance that keeps your system running efficiently and prevents breakdowns when you need cooling most. Our certified technicians perform a thorough inspection and tune-up: we check thermostat calibration, measure airflow and temperature split, clean condenser and evaporator coils, replace or wash filters, clear the condensate drain, verify refrigerant charge, tighten electrical connections, test capacitors and contactors, lubricate moving parts, assess ductwork, and confirm safe, reliable operation. This process identifies and resolves common issues—reduced airflow, warm spots, unusual noises, foul odors, frozen coils, drainage clogs, dirty coils, low refrigerant, failing capacitors, and short cycling—so problems are fixed fast and comfort is restored.
