How Hammond Businesses Use Our Maintenance Plans
Most of our Hammond plan clients run quarterly visits. That spacing catches refrigerant drift, dirty coils, and weak capacitors before the summer or winter peak. For restaurants and grocery operations we add monthly walk-in inspections during the hot months because a single failed evaporator fan in July can dump thousands of dollars of inventory.
What Plan Clients Tell Us
The two things Hammond plan clients consistently say after their first year: their average repair bill dropped, and they stopped getting surprised by failures. That is the whole point. Documented readings let our techs spot a slow leak or a weak compressor while it is still cheap to fix.
