Reliable, High-Quality AC Repair to Restore Comfort Fast

AC Repair and Reading MA’s Trusted Heating & Cooling Professionals — Your Local Experts

At SumZero Energy Systems, our AC Repair begins with a precise, multi-point diagnostic to quickly pinpoint issues and get cool air flowing again. We check thermostats and controls, air filters and airflow, electrical components (capacitors, contactors, relays), refrigerant pressures and potential leaks, coil condition, drain lines, and ductwork to resolve common problems like warm air, short cycling, weak airflow, unusual noises, odors, frozen coils, water leaks, and tripped breakers. Once identified, we make targeted repairs—cleaning and restoring coils, clearing condensate drains, replacing failed parts, sealing and verifying refrigerant leaks with proper recharge, balancing airflow, recalibrating thermostats, and verifying performance under load. Beyond repairs, we offer comprehensive solutions including seasonal maintenance and tune-ups, new system installation and replacement, ductless mini-splits and heat pumps, furnace and boiler service, indoor air quality upgrades, smart thermostats, ductwork design and sealing, and efficiency improvements. Expect exceptional service, quality craftsmanship, clear communication, and work done right the first time. Proudly and professionally serving the Reading, MA area.
