Heat Pump Maintenance from SumZero Energy Systems keeps your home comfortable and your system running efficiently by combining thorough diagnostics with proactive care: we inspect airflow and ducting, measure refrigerant charge and pressures, test electrical components and safeties, calibrate thermostats, clean coils, clear condensate drains, verify the defrost cycle, tighten connections, and perform a complete performance check. This process identifies and resolves common problems such as weak airflow, uneven temperatures, dirty coils, clogged filters, refrigerant leaks, icing, noisy operation, short cycling, high energy bills, and nuisance error codes—often before they become costly breakdowns. Beyond maintenance, we provide expert repairs, new system installations and replacements, ductless mini-splits, indoor air quality solutions, ductwork improvements, smart thermostats, energy-efficiency upgrades, and maintenance plans.
