Kelvex Heating & Air

Preventative maintenance agreements

Most HVAC failures are things somebody could have seen coming. A maintenance agreement is how you find them in April instead of during a July dinner rush — or a January cold snap.

How it works

  1. Walkthrough. We inventory every unit on the property — make, model, serial, age, refrigerant type, and current condition.
  2. Written proposal. You get a per-unit, per-visit price and a recommended schedule based on the equipment, not a flat package we sell everyone.
  3. Scheduled visits. Typically twice a year — cooling season and heating season — or quarterly for kitchens, breweries and other hard-duty environments.
  4. Report every visit. Checklist, readings, and photos for each unit, delivered after the visit. Repairs found are quoted separately and never done without approval.

What a cooling visit covers

  • Filters replaced, coils inspected and cleaned as needed
  • Refrigerant performance verified by superheat and subcooling
  • Compressor and motor amp draw against nameplate
  • Contactors, capacitors and electrical connections inspected
  • Condensate drain cleared and pan checked
  • Belts, bearings and blower wheel inspected
  • Economizer operation and damper travel verified
  • Supply and return temperature split recorded
  • Evaporative sections: pump, media, water level, sump condition

What a heating visit covers

  • Burner and ignition system operation
  • Flame sensor cleaning and microamp reading
  • Gas pressure verified at manifold
  • Heat exchanger inspection
  • Safety circuit testing — limits, rollouts, pressure switches
  • Blower operation and temperature rise against nameplate
  • Evaporative sections: winterization, drain and blow-down

Why the report matters

If you manage a property, the report is the point. It gives you a documented equipment history for budgeting, a paper trail for ownership, and evidence when a unit needs replacing rather than another repair. It also means when someone else works on that roof, there's a record of what condition things were in.

Pricing

Maintenance is priced per unit, per visit, and depends on equipment type and count. Multi-unit properties are priced lower per unit. See pricing for how our rates are structured, or request a walkthrough for a written number.
