Commercial RTU Maintenance in San Jose — Preventive HVAC Service Under $600

Commercial RTU Maintenance for a Dental Clinic

Preventive maintenance was completed for a commercial rooftop HVAC system serving a dental clinic. The RTU combines gas heating and electric cooling, requiring detailed inspection and regular servicing to ensure safe, reliable, and energy-efficient operation.

The maintenance included cleaning and inspection of condenser and evaporator coils, air filter replacement, drainage system inspection, electrical diagnostics, thermostat and control testing, gas heating service, refrigerant level checks, compressor inspection, fan and motor servicing, and complete operational testing in both heating and cooling modes.

Additional Work Included:

• belt and pulley inspection
• vibration and noise diagnostics
• tightening electrical connections
• inspection of equipment cabinet and mounting integrity
• testing of all safety and emergency shutoff controls

One of the biggest advantages of regular RTU maintenance is long-term cost savings. Early detection of minor issues helps prevent major breakdowns, emergency service calls, expensive repairs, and business downtime.

Cost efficiency: Total maintenance cost for this commercial project was under $600 — significantly lower than emergency rooftop HVAC repairs or equipment replacement.

Preventive maintenance helps extend equipment life, improve energy efficiency, reduce operating costs, and ensure stable HVAC performance during peak summer and winter seasons.
