Preventative Maintenance

Most commercial facilities budget for repairs. The ones that run smoothly budget for maintenance instead. Wolfe Mechanical provides structured PM contracts for commercial and residential clients across Santa Clara County — quarterly, biannual, and annual plans that keep systems running and repair bills predictable.

You Change the Oil in Your Fleet. Do the Same for Your HVAC

Prevent problems before it's too late

Preventative maintenance works on the same logic as any scheduled service interval. Skip it long enough and what would have been a $200 fix becomes a $3,000 repair or a full system replacement. Commercial HVAC systems that run without structured maintenance don't last as long, fail more often, and cost more to operate — and the breakdowns rarely happen at a convenient time.


A PM contract with Wolfe Mechanical means your system gets serviced on schedule, every time, without you having to initiate it. We track the intervals, schedule the visits, and document what we find. You stay focused on running your facility. Serving Santa Clara County, San Mateo County, and Alameda County — including San Jose, Campbell, Los Gatos, Gilroy, Morgan Hill, Sunnyvale, Gilroy, San Mateo, San Carlos, San Bruno, Fremont, and Livermore.

A Thorough Visit. Not a Checkbox

WHAT GETS CHECKED
Every scheduled maintenance visit from Wolfe Mechanical covers the components that actually cause failures when neglected. This isn't a visual inspection and a signature — it's a working service call.
What our technicians check and service on every PM visit:


  • Filter inspection and replacement
  • Refrigerant pressure checks and leak inspection
  • Evaporator and condenser coil cleaning
  • Belt tension and motor bearing inspection
  • Thermostat calibration and programming verification
  • Electrical connection checks and voltage readings
  • Drain pan and condensate line clearing
  • Overall unit cleaning and visual assessment of wear components


After every visit, you receive a written summary of findings — what was serviced, what was flagged, and what to watch going forward. No guesswork about what happened during the visit.

The Facilities That Can't Afford a Surprise Breakdown

WHO WE MAINTAIN FOR

Commercial PM contracts aren't one-size-fits-all. The stakes are different depending on what your facility runs and what goes wrong when it stops.

  • Restaurants and Commercial Kitchens
  • School Districts and Educational Facilities
  • Commercial Buildings and Property Management
  • Industrial and Technical Facilities

Quarterly Maintenance

Four visits per year. Recommended for high-use commercial facilities — restaurants, school districts, data centers, and any building where HVAC or refrigeration runs continuously or near-continuously. At this frequency, filter loading, refrigerant drift, and wear on moving components get caught before they compound into larger failures. Quarterly contracts are the foundation of a proactive maintenance program.

Biannual Maintenance

Two visits per year, typically scheduled at the seasonal transitions — spring before cooling season and fall before heating season. Well-suited for schools, homes, light industrial facilities, and properties where systems run at moderate load. Biannual service keeps systems calibrated for seasonal demand shifts and catches off-season wear before peak load hits.

Annual Maintenance

One comprehensive visit per year. Appropriate for lower-load residential systems and light commercial applications where usage is limited and risk tolerance is higher. Annual contracts establish a documented service baseline and ensure systems meet manufacturer maintenance requirements for warranty compliance.

What Facility Managers Ask About PM Contracts

  • How often should commercial HVAC be serviced?

    High-use commercial facilities — restaurants, schools, data centers — benefit most from quarterly service. Office buildings and light commercial properties are well-served by biannual plans. Annual service is appropriate for lower-load residential systems and light commercial applications. If you're unsure which interval fits your facility, call us and we'll walk through it with you.

  • What is included in a commercial HVAC preventative maintenance contract?

    Every visit includes filter inspection and replacement, refrigerant pressure checks, coil cleaning, belt and motor inspection, thermostat calibration, electrical connection verification, drain line clearing, and a written service summary. Scope can be adjusted based on system type and facility requirements.

  • What does a PM contract cost?

    Pricing depends on your system count, equipment type, service frequency, and facility size. We don't publish flat rates because the right contract is built around what you actually run. Contact us for a quote and we'll give you a straightforward number.

  • Can I get HVAC and refrigeration covered under one contract?

    Yes. We maintain both HVAC and commercial refrigeration systems, which means we can structure a single contract that covers all mechanical systems in your facility. Most commercial clients find this simpler to manage than separate vendor relationships.
