HVAC Preventive Maintenance
HVAC Preventive MaintenanceImproved Efficiency
Mechanical systems don’t fail all at once. Performance slips first: comfort complaints rise, energy use creeps up, valves and actuators drift, drains clog, sensors fall out of calibration, and minor leaks turn into shutdowns. Ahern’s Mechanical Preventive Maintenance Agreement is a proactive program for HVAC that reduces breakdowns, extends equipment life, and improves efficiency. Your time is important, which is why Ahern’s teams come prepared to make common repairs due to your HVAC preventive maintenance agreement.
Nearly 28,000 clients have a primary technician assigned to their facility.
Every one of your techs that have been here for us has always been courteous and professional. They always let me know what is going on in a manner that I can understand before they leave.

HVAC Preventive Maintenance Benefits
- Reduced downtime through scheduled inspections, tune-ups, and early issue detection.
- Extended equipment life and improved reliability.
- Clear visibility into equipment condition, deficiencies, and recommended next steps.

Your agreement is built around your equipment and operating conditions—not a one-size-fits-all checklist.
Tasking is customized based on:
- Environmental conditions (dusty, dirty, humid, rooftop exposure, process environments)
- Run times and occupancy patterns.
- Age, type, and application of the equipment.
- Customer priorities for comfort, reliability, energy efficiency, and uptime.
In the last 18 months, we have completed 7,085 mechanical PM inspections.
We are very pleased with the quality of work, attention to detail, and the value of maintaining a schedule that your personnel demonstrated.
Planned HVAC maintenance is structured to prevent comfort issues, protect critical components, and identify failure risks early.
Common task categories include:
- Unit inspections (casing/panels, curb/flashing, safety labels, power checks)
- Airside performance (filters, dampers, economizers, drainage, cleanliness around units)
- Blowers & motors (belts, sheaves, bearings, vibration/noise, electrical connections, volts/amps recorded)
- Cooling checks (leaks, controls/safeties, coils, refrigerant charge indicators, pressures, subcooling/superheat)
- Heating checks (gas train/leak checks, ignition, burners, safeties, sequence of operation, smooth light-off)
- All tasking is recorded per unit, with deficiencies and recommendations documented for action and planning.
How Ahern Customizes Your HVAC Preventative Maintenance
1) Know your equipment & risks
A qualified technician surveys your systems, documents make/model/serial information, confirms access and safety requirements, and learns how the building operates—run times, occupancy patterns, and comfort priorities.
2) Build the right scope
Tasking is tailored by equipment type, age, manufacturer guidance, environment, and operational application.
3) Prevent breakdowns early
Your assigned technician completes planned inspections and tune-ups with consistent tasking and clear documentation—flagging deficiencies early, before they become outages.
4) Turn findings into a clear plan
You receive straightforward documentation and visibility into deficiencies and recommendations—supported by your customer portal for ongoing tracking and planning.
5) Get priority help when it counts
If issues arise, agreement customers receive priority scheduling—and free quotes for repairs and improvements to support approvals and budgeting.
Documentation that makes budgeting and planning easier
- Equipment list/inventory (as scoped) and service history.
- Deficiency tracking with recommended corrective actions.
- Repair and improvement proposals at no cost.
- Equipment grading and life-expectancy insights for capital forecasting.
- A practical roadmap to improve reliability and efficiency.
