AC Maintenance
AC Maintenance Built Around Measured System Condition
A useful tune-up is more than a quick visual check. CMB HVAC evaluates operation, electrical condition, airflow, drainage, controls, and cooling performance so the homeowner understands what is working, what needs attention, and what can wait.

AC Maintenance Built Around Measured System Condition
Our AC tune-up is a scheduled inspection and performance check — not a guarantee that nothing will ever fail. The visit covers controls, electrical condition, motors, condensate drainage, filters, coils, airflow, and cooling operation, with actual readings taken at each step so the report says something real about your system.
Findings come back sorted into three buckets: what needs attention now, what's worth planning for, and what can simply be monitored. That report is the difference between a tune-up and a glance — and it's what lets you fix a weakening capacitor in May instead of meeting it during a July no-cool call.
Measured, Cleaned, Reported
You'll see what we saw: the readings, the photos, and the priorities — whether the answer is 'all clear' or a short list.
A real checklist
Every item below is actually performed and initialed — no vague '21-point' number with no definitions behind it.
Findings in writing
Measurements and photos come home with you, so next year's visit has a baseline to compare against.
Cleaning included where it counts
Condensate line treatment and standard coil rinsing are part of the visit; heavy restoration work is quoted separately, never silently skipped.
Booked before the rush
Membership visits go on the calendar ahead of peak season — spring for cooling, fall for heating.
When to Schedule AC Maintenance
Spring, before the heat
April through early June is the sweet spot along the Wasatch Front: comfortable working conditions and open appointment slots before the first heat wave.
Cooling has gotten uneven
Rooms that used to keep up and now don't often trace back to airflow and coil condition — exactly what the tune-up measures.
Bills creeping upward
A system working against a dirty coil or a failing motor draws more power for the same cooling. Maintenance won't fix everything, but it will tell you what changed.
After any repair
A repair fixes one part; the visit's report covers the rest of the system so the next call isn't a surprise.
What an AC Tune-Up Includes
Stated plainly, so you know what you're getting — and what would be quoted separately.
- Thermostat and controls — settings, calibration, and the call for cooling
- Electrical connections tightened and components readings-recorded: capacitors and contactor under load
- Blower motor and condenser fan motor — amp draw measured against nameplate
- Condensate drain flushed and treated; float switch tested
- Filter condition checked (standard sizes available on request)
- Evaporator and condenser coil condition inspected; outdoor coil rinsed
- Temperature split and airflow measured across the system
- Refrigerant readings taken when the numbers indicate — with any anomaly explained, not sold
How the Tune-Up Visit Runs
Thermostat & startup
We confirm controls and calibration, run the system, and watch it start — hard starts tell on weak capacitors immediately.
Electrical under load
Capacitors and contactor are measured while running, not just eyeballed. Readings go on the report whether they're good or not.
Water & airflow
Drain flushed and switch tested, filter checked, blower and temperature split measured — the pair that decides whether cooling reaches the rooms.
Coils & cabinet
Both coils inspected, the outdoor coil rinsed, cabinet panels sealed — where Utah's dust and cottonwood do their annual damage.
Report & priorities
You get the findings sorted: fix now, plan for it, keep an eye on it. Photos and measurements included.
One-Time Tune-Up or Membership
Both get the same checklist and the same report. The difference is what happens next season.
One-time tune-up
Book a single cooling check whenever it suits. Same checklist, same written report, and a baseline on file for future visits.
Best for: newer systems, recent inspections, or try-it-first homeowners
Maintenance membership
Scheduled seasonal visits — furnace before winter, AC before summer — booked ahead of the rush, with the report history building year over year.
Best for: systems you plan to keep running for years, busy calendars
Wait for a breakdown
The honest third option: some systems run years without a tune-up. The trade-off is that weak capacitors and clogged drains announce themselves at the worst possible hour.
Best for: nobody, if we're honest — but the report will tell you if your system is the exception
What a Tune-Up Covers — and What It Doesn't
Maintenance and repair are different jobs, and pretending otherwise is how tune-ups get a bad name.
The visit price covers the inspection, standard cleaning, and the report. Here's the line between that and quoted work.
Included: inspection & measurement
Every check on the list above, with readings recorded and explained.
Included: standard cleaning
Condensate line flush and treatment, outdoor coil rinse, and cabinet cleaning are part of the visit.
Quoted separately: heavy restoration
A coil matted with years of cottonwood, or a drain line needing more than a flush, gets its own flat-rate quote before any of that work starts.
Quoted separately: worn parts
If the readings show a capacitor on its way out, replacing it is a repair with its own written price — your call, never auto-billed.
Maintenance improves the odds and documents the condition — it does not prevent every breakdown or guarantee lower utility bills, and anyone promising both is selling. Refrigerant is not part of a tune-up: a healthy sealed system doesn't consume it, so 'adding refrigerant' is a leak repair quoted on its own.
From Doorstep to Report
Protect & connect
Floor protection down, system running, and a quick conversation about anything you've noticed — your observations steer the inspection.
Inspect & measure
The full checklist, with a meter and gauges doing the talking. Readings recorded as we go.
Clean & adjust
Drain flushed, coils rinsed, connections tightened, and anything minor corrected on the spot within the visit's scope.
Report & next steps
Findings sorted into now / plan / monitor, with photos. If anything needs a repair, it's a written flat-rate option — not a surprise.
Why Wasatch Front Coils Need Their Spring Rinse
Our dry climate is gentle on people and rough on outdoor units. Fine dust rides every breeze, cottonwood season coats condensers in white seed for a few weeks each June, and new construction along the corridor throws drywall dust and dirt into the air for years at a stretch. An outdoor coil that breathes freely is the difference between a system that cruises through August and one that limps — so the spring rinse is the single highest-value item on the checklist.
- Best scheduling window: April through early June, before sustained heat
- Homes near busy roads or active construction collect dust faster — mention it when you book
- Fall works too, paired with the furnace tune-up — one visit, both seasons covered
