Scheduled attention on every unit, written down, so failures stop arriving as surprises and replacement becomes a budget line instead of a bad afternoon.
Why it pays
Nearly every emergency was visible months earlier
A condenser coil packed with valley dust raises head pressure, which raises amp draw, which cooks a compressor in August. A belt that was glazed in March shreds in July. A blocked condensate drain floods a ceiling long before anyone hears about it.
None of that is dramatic on the day it is found. All of it is expensive on the day it fails — usually at the worst possible moment, because equipment fails when it is working hardest.
A maintenance agreement is not a magic contract. It is somebody competent looking at your equipment on a schedule and writing down what they saw.

What a visit covers
The actual checklist
Not every item applies to every unit. What does apply gets done, measured and recorded — and you get the numbers, not just a tick.
Airside
Filters changed and sizes recorded
Evaporator and condenser coils inspected and cleaned
Blower wheel condition, belt tension and alignment
Bearings, motor mounts and vibration
Economizer dampers, actuator and linkage
Supply and return temperature split

Suction and discharge pressures logged
Superheat and subcooling calculated
Visual leak inspection at joints and service ports
Compressor amp draw against nameplate
Defrost operation and termination (refrigeration)
Line insulation condition
Electrical & controls
Contactors, relays and pitting
Capacitor readings against rating
Terminal tightness and wire condition
Safety and limit controls proven
Thermostat operation and schedule verified

Site left clean, panels secured, roof hatch closed
Agreement levels
Three shapes of agreement
Which one fits depends on how much downtime actually costs you and how dirty the environment is. We quote per site after the condition survey — equipment count, access and run hours all change the number.

Cooling & heating
No prices are shown anywhere on this site. A commercial maintenance price depends on the
unit count, equipment type, roof access and run hours, and quoting it blind would be guessing.
Asset listEvery unit, tagged and recordedLocation, make, model, serial, year, refrigerant type, filter sizes and belt sizes. Plain format, yours to keep — including if you ever move to another contractor.
Visit recordReadings, not ticksPressures, temperatures, amp draws and what was replaced, so the trend across visits is visible instead of each visit standing alone.
Repair forecastWhat is coming, and roughly whenUnits flagged as healthy, watch, or plan-to-replace, with the reasoning. This is the document that turns a capital replacement into a budget decision.

Questions
About agreements
How many maintenance visits a year does a commercial unit need?
Two is the usual baseline for packaged rooftop equipment — once before the cooling season and once before heating. Kitchen exhaust, refrigeration and units in dusty agricultural environments generally need quarterly attention, because the condensers load up far faster than they do elsewhere.
What happens on the very first visit?
The first visit is a condition survey rather than a service. We locate and tag every unit, record model, serial, age, refrigerant type and condition, note anything unsafe or already failing, and hand you a written asset list. That list is yours to keep, whoever services the equipment afterwards.
Does an agreement include repairs?
The agreement covers the scheduled visits and the consumables listed in it — filters, belts, coil cleaning, drain treatment. Repairs are quoted separately and always approved by you before they are carried out. Nothing is done silently and added to an invoice.
Can you maintain equipment that another contractor installed?
Yes, and that is most of the work. Who installed it does not matter; its condition does. The condition survey on the first visit gives us, and you, an accurate starting point.
What if a unit is too far gone to keep maintaining?
We tell you. A unit with a failing compressor, a leaking coil and an obsolete refrigerant is a replacement conversation, not a maintenance one. You get the repair figure and the replacement figure and you choose — we do not keep charging to maintain something that should be changed out.
