Preventative Maintenance Programs for Commercial HVAC Systems in Waukesha & Milwaukee
Protect your investment and keep your facility running smoothly year-round with a professional commercial HVAC maintenance program from Advanced Chiller Services. Our preventative maintenance plans are designed for busy facility managers, building owners, and anyone responsible for the reliability of comfort systems in offices, schools, retail, or industrial sites. Regular HVAC maintenance isn’t just a best practice—it’s the key to avoiding costly breakdowns, extending equipment lifespan, and ensuring your systems operate at peak efficiency.
Why Choose a Preventative Maintenance Plan?
HVAC systems are significant capital investments, and downtime can disrupt your business, drive up costs, and cause discomfort for occupants. Scheduled maintenance helps you:
Prevent unexpected failures and reduce emergency repairs
Maximize energy efficiency—saving money on utility bills
Extend the usable life of expensive equipment
Meet warranty requirements for major manufacturers
Ensure safe operation, compliance, and air quality
Enjoy priority scheduling and peace of mind year-round
What’s Included in Our Maintenance Programs?
We offer comprehensive service contracts customized to your facility’s equipment and needs. Typical maintenance visits include:
Seasonal Inspections
Dedicated cooling and heating system checkups—catching issues before summer or winter peaks.
Cleaning & Tune-Ups
Coil cleaning, filter replacements, lubricating moving parts, checking belts, and tightening electrical connections.
Performance Checks
Measuring refrigerant levels, verifying thermostat calibration, airflow balancing, checking boiler safety controls, and more.
Safety & Compliance
Inspecting for carbon monoxide risks, pressure irregularities, and verifying compliance with all codes.
Documentation & Reporting
You receive a detailed report after each visit, outlining work performed, equipment condition, and any recommended actions or repairs.
Our plans can cover all your critical HVAC assets: chillers, boilers, rooftop units, split systems, controls, and ventilation systems.

Flexible Service to Match Your Operation
No two facilities are the same, so we tailor maintenance plans to your unique requirements—monthly, quarterly, or bi-annual service schedules are available. We work around your hours, offering off-peak visits for schools or 24/7 operations to minimize disruption. If you need only seasonal tune-ups or want comprehensive, all-inclusive care, we’ll design the right program for you.
