Commercial HVAC Preventive Maintenance

Equipment rarely fails without warning. It fails after a season of running on a loaded filter bank, a slipping belt, or a charge that has been drifting for a year. Dual Temp Commercial Services builds preventive maintenance programs around your actual equipment list and operating calendar, catching those conditions before they become emergency calls.

Maintenance Programs Across Eastern PA

Tasking You Can Actually Verify

Plenty of maintenance agreements amount to a technician walking the roof twice a year. Ours specify what gets done per unit per visit: filters and belts, coil condition, refrigerant charge verified against superheat and subcooling, combustion analysis on gas equipment, amp draw compared to nameplate, economizer stroke and sensor calibration, and control sequence spot checks.

Every visit produces a written report tied to your equipment list, including deficiencies found, work performed, and anything that should be budgeted for the next cycle. Facility managers use those reports for capital planning, not just for the file.

What a Program Includes

Built Around Your Equipment, Not a Template

Program scope scales with what you run and how critical it is. A single-tenant office and a hospital do not need the same visit frequency.

Scheduled Maintenance Visits

Quarterly, semiannual, or monthly visits depending on equipment type and criticality. Each visit follows equipment-specific tasking, not a generic checklist, and covers the mechanical, electrical, and controls side of each unit.

Seasonal Changeover

Spring cooling startup and fall heating startup, timed ahead of the first stretch of demand. Cooling changeover covers coils, charge, economizers, and condensate. Heating changeover covers combustion, safety circuits, and heat exchanger inspection, which is when cracked exchangers and weak flame signal get caught.

Filters, Belts & Consumables

Filter and belt programs sized to your equipment and run hours, stocked and replaced on schedule. Restricted airflow is the single most common cause of capacity complaints, and it is the cheapest one to prevent.
