Annual HVAC Tune-Up & System Check

Pre-season system inspection: airflow, refrigerant, thermostat calibration, electrical, safety controls.

What This Service Covers

The Full Scope

A proper tune-up extends equipment life, catches small problems before failure, and restores rated efficiency. We measure static pressure, check refrigerant charge, calibrate the thermostat, tighten electrical connections, and clean accessible coils.

What's Included

  • check_circle Static pressure test
  • check_circle Refrigerant level check
  • check_circle Thermostat calibration
  • check_circle Electrical tightening + amp draw
  • check_circle Safety control verification
  • check_circle Filter inspection

21-point annual tune-up is the highest-ROI HVAC service you can buy. $99 to find a $129 capacitor before it kills the $800 compressor it's wired to. That's the math.

Who Calls Us Most

3 Households That Get the Biggest Win

01

Homeowners with newer HVAC (warranty-protected)

Most manufacturer warranties REQUIRE annual professional service. Skipping voids coverage.

02

Older systems (10+ years)

Tune-up catches small problems early — capacitor swap is $150, system replacement is $8,000+.

03

Allergy households

Tune-up includes filter check + airflow tune; both directly affect IAQ.

Utah Climate × This Service

Why HVAC Tune-Up Is a Different Job in Utah

Inversion. Wildfire smoke. Dry-air winters. Lake-effect dust. Each one shifts how this service performs — and when it pays off most.

thermostat Dec–Feb

Winter Furnace Peak Load

Sub-zero nights push furnaces to 100% runtime. Skipped tune-ups manifest as mid-blizzard failures — schedule fall tune-up to avoid emergency service rates.

wb_sunny Apr–May

Spring AC Pre-Season

Catch low refrigerant + weak capacitors before May 90°F days. Pre-season tune-up prevents the most expensive emergency call: AC failure on day 1 of summer.

local_fire_department Jul–Sep

Wildfire Filter Stress

Filters clog 3x faster during smoke events. Mid-summer tune-up confirms airflow + filter + coil are coping with elevated particulate load.

cyclone Dec–Feb

Inversion Combustion Quality

Stagnant outdoor air during inversion can affect gas furnace combustion. Tune-up combustion analysis catches incomplete burn before CO becomes an issue.

Best Time to Schedule

When to Book — by Season

Q1

Spring (April–May)

AC tune-up window. Catch refrigerant + capacitor issues before peak heat.

Q2

Summer (June–Aug)

Mid-season check on heavily used systems running 12+ hr/day.

Q3

Fall (Sep–Oct)

Furnace tune-up — heat exchanger crack check is critical safety.

Q4

Winter (Dec–Feb)

Mid-winter health-check on systems running constantly.

Set The Record Straight

Myths vs. Facts

Myth

"My system is new — it doesn't need a tune-up."

Fact

New systems need annual service to keep warranty active. Skip a year, lose coverage.

Myth

"Tune-ups are upsell traps."

Fact

Real tune-ups are 21-point with documented measurements. Ask for the static-pressure reading and the amp-draw on the blower — both written.

Myth

"I can DIY everything except gas."

Fact

Refrigerant access requires EPA 608 certification. Capacitor testing requires dual-cap meter. Combustion analysis needs a calibrated CO instrument.

Between Visits

HVAC Tune-Up — Homeowner Tips

Things you can do between Liberty visits to maximize the result. No upsell — just better outcomes.

tips_and_updates

Take a phone photo of the thermostat reading vs an indoor probe thermometer monthly — drift over 2°F means recalibration needed.

tips_and_updates

Listen for new sounds: a healthy system makes 1 sound (the blower). Squealing, clicking, hissing all indicate issues.

tips_and_updates

Check the outdoor condenser monthly during AC season — clear leaves, grass clippings, and snow.

tips_and_updates

Replace filter on a regular calendar reminder, not "when it looks dirty" — dirt is invisible until 30%+ blockage.

tips_and_updates

Notice runtime — if the AC is running 90 minutes for a 5° drop on a mild day, something is wrong.

tips_and_updates

Keep HVAC service records (PDF emails are fine) — manufacturer warranty requires this proof.

Stop & Call Us Same Day

If you see any of these, do not wait for your next scheduled visit.

priority_high

Furnace smells like rotten eggs — gas leak, leave the home and call utility immediately.

priority_high

AC outdoor unit makes loud humming but fan is not spinning — capacitor failure, system will overheat.

priority_high

Visible ice on refrigerant lines mid-summer — low charge or restricted airflow; turn off until serviced.

Honest Split

DIY vs. Liberty — Who Should Do What

Task DIY Pro Why
Thermostat battery + setting checks check_circle Annual.
Filter replacement check_circle Quarterly.
Outdoor unit cleaning (rinse + clear debris) check_circle Twice per AC season.
Refrigerant top-up check_circle EPA Section 608 certification required.
Capacitor + contactor testing check_circle High-voltage; needs dual-cap meter and PPE.
Combustion analysis check_circle Calibrated CO instrument + gas-line work.
