Refrigerant Charge Check
Superheat and subcool measured — not just 'pressures look okay.' A system 10% undercharged costs you 20% in efficiency.

Overview
The Valley kills unmaintained HVAC systems. Annual tune-ups keep yours running through July.
A residential AC in Phoenix runs 3–4x the hours of one in a moderate climate. Refrigerant charge drifts, capacitors weaken, blower wheels load up with dust, condenser coils fill with cottonwood and dryer lint. Skipping annual maintenance in the Valley isn't 'saving money' — it's guaranteeing a $600 emergency call in the middle of July.
We recommend two tune-ups a year: spring (cooling) and fall (heating). Both are multi-point inspections that catch small failures before they become emergency calls.
Every tune-up is documented — refrigerant pressures, capacitor readings, static pressure, temperature split, amperage draw. You get the numbers, not just 'looks good.'
Our maintenance plan customers get priority scheduling in peak season and a discount on any repairs identified during service.
What's Included
The scope of a Saguaro maintenance & tune-ups job.
Written scope, fixed pricing, and a real technician on every visit — not a subcontractor you've never met.
02
Capacitor Testing
Weak capacitors are the #1 cause of Valley summer no-cool calls. We measure, we don't guess.
03
Coil Cleaning
Condenser coils rinsed clear of dust, cottonwood and pet hair. Restricted coils crush efficiency and shorten compressor life.
04
Blower & Fan Inspection
Blower wheel condition, motor amperage, bearing check, belt condition where applicable.
05
Electrical Inspection
Contactor condition, wire tightness, disconnect condition — burned contacts kill compressors.
06
Drainage Check
Condensate line flushed, overflow switch tested. A clogged drain floods your attic in July.
07
Thermostat Calibration
Verify accurate temperature reading, verify staging, verify system controls.
08
Combustion Analysis (Fall)
Gas furnaces get CO testing, combustion analysis and heat exchanger inspection every fall.
Our Process
How a Saguaro Mechanical maintenance & tune-ups job actually goes.
- 01
Scheduled Visit
One appointment in spring, one in fall — booked in advance.
- 02
Multi-Point Inspection
Full documented inspection of every mechanical, electrical and refrigerant component.
- 03
Written Report
You get the numbers — pressures, readings, wear condition — not a vague thumbs-up.
- 04
Prioritized Findings
Anything needing attention is flagged as immediate, this-year or watch-item.
Why It Matters
What you actually get out of it.
Fewer Emergency Calls
Systems that are inspected twice a year fail dramatically less often — and almost never on the hottest week of the year.
Longer Equipment Life
Well-maintained residential systems last 15+ years. Neglected Valley systems often quit at 8–10.
Lower Utility Bills
A properly charged, clean-coil system can run 15–25% more efficiently than a neglected one.
Warranty Protection
Most manufacturer warranties require documented annual maintenance. We keep the paperwork so your claim stays valid.
Priority Scheduling
Maintenance plan customers get moved to the front of the line during peak-season no-cool calls.
Frequently Asked
Maintenance & Tune-Ups
questions.
How often should HVAC be serviced?
+
Twice a year in the Valley — spring for cooling, fall for heating. Systems here run far more hours than in most of the country, so annual-only maintenance is genuinely undermaintenance.
What's included in a tune-up?
+
Full multi-point inspection: refrigerant pressures, capacitor readings, coil condition, blower and fan check, electrical inspection, drainage check, thermostat verification. Fall visits add CO testing and combustion analysis on gas furnaces.
Do you offer a maintenance plan?
+
Yes — an annual plan covers both spring and fall visits, includes priority scheduling, and applies a discount on any repairs found during service.
How long does a tune-up take?
+
About 60–90 minutes per system for a thorough visit. We're not the 15-minute-check-a-box outfit.
Will you try to sell me repairs?
+
We'll show you what we find with actual measurements. Immediate safety issues are called out as such. Watch-items are labeled as watch-items. You decide.
