COMMERCIAL PREVENTIVE MAINTENANCE

Planned Maintenance for Rooftop & Packaged HVAC Equipment

 

Commercial HVAC equipment often operates for long hours under demanding conditions. Routine preventive maintenance can help identify developing problems, maintain proper airflow and operation, and reduce the likelihood of unexpected equipment failures.


Commercial maintenance may include:

  • Filter inspection and replacement
  • Belt inspection, adjustment and replacement as needed
  • Coil inspection and cleaning as needed
  • Condensate drain inspection and clearing
  • Electrical component and connection inspection
  • Motor, blower and fan inspection
  • Thermostat and control verification
  • Refrigeration-system evaluation
  • Heating and cooling operation checks
  • Lubrication of accessible serviceable components where applicable


Scheduled Maintenance Agreements

L & J Cooling and Heating can develop recurring preventive-maintenance schedules for businesses with individual systems or multiple rooftop units. Maintenance frequency and scope can be tailored to the equipment, operating conditions and needs of the property.

COMMERCIAL HVAC EXPERIENCE

Multi-Unit Commercial HVAC Service

L & J Cooling and Heating services commercial properties with multiple rooftop and packaged HVAC systems. Our work includes diagnostics, repairs, preventive maintenance and equipment-condition evaluation. 

Rooftop Unit Service & Maintenance

From routine filter and belt service to refrigeration, electrical and airflow diagnostics, we provide hands-on commercial HVAC service designed around the needs of the property and its equipment. 

COMMERCIAL HVAC REPAIR & REPLACEMENT

Repair When Practical. Replace When It Makes Sense.

Commercial HVAC problems do not always require equipment replacement. L & J Cooling and Heating evaluates the system, identifies the cause of the problem and explains the available options before recommending the next step.


Repair may make sense when:

  • The problem is isolated
  • Replacement parts are available
  • The equipment is otherwise in good condition
  • Repair cost is reasonable compared with overall system condition


Replacement may be worth considering when:

  • Breakdowns are becoming frequent
  • Major components are failing
  • Equipment is aging or unreliable
  • Operating costs are increasing
  • Comfort or performance has declined
  • Repair costs are becoming difficult to justify


When replacement is appropriate, we can help compare equipment options, efficiency, controls and long-term operating costs for the property.
