HVAC Tune-Up in Columbia, Missouri

An HVAC tune-up isn’t a checklist — it’s a measurement protocol that documents equipment condition against manufacturer specification. PolarCore’s tune-up on either furnace or AC equipment records combustion analysis or refrigerant charge, static pressure, temperature rise or temperature split, ignition sequence or capacitor microfarad readings, amperage draw against nameplate, and other measurements that establish objective baseline for equipment condition. Measurements upload to the customer’s ServiceTitan record so equipment condition trends over years of service. Tune-up findings that require repair get quoted transparently; the customer decides whether to authorize on the same visit or schedule separately. A tune-up on well-maintained equipment typically takes 60–90 minutes; a tune-up that turns up problems takes longer and pivots into diagnostic mode.

Furnace Tune-Up Protocol

1. Visual inspection of equipment, venting, combustion air, condensate management, gas piping
2. Cabinet cleaning — burner assembly, blower compartment, controls area
3. Filter inspection and replacement
4. Ignition sequence verification — inducer draft, pressure switch, hot surface igniter or spark ignition, flame establishment, flame proving
5. Flame sensor cleaning with fine steel wool; microamp reading verification with Fieldpiece SC680 (target: >3.0 µA on well-maintained equipment)
6. Manifold gas pressure verification and adjustment against 3.5″WC natural gas or 10″WC LP specification using a manometer
7. Pressure switch operation verification — continuity, tubing inspection, actual draft measurement
8. Static pressure measurement across the air handler using a Testo 510 manometer
9. Temperature rise measurement across the heat exchanger (30–60°F rise per manufacturer specification)
10. Combustion analysis at the flue with a Bacharach Fyrite Insight — CO ppm, O⊂2 %, CO⊂2 %, stack temperature
11. Heat exchanger visual inspection — borescope inspection through burner ports on equipment 10+ years old
12. Blower motor amperage verification against nameplate FLA
13. Condensate drain flush on 90%+ AFUE equipment
14. Safety limit switch operation verification
15. Thermostat calibration and control voltage verification
16. Written tune-up report with measurements documented

AC Tune-Up Protocol

1. Visual inspection of outdoor condenser, refrigerant line insulation, evaporator coil, condensate management
2. Outdoor coil cleaning — fin cleaner and rinse
3. Evaporator coil inspection — biological growth, fin condition, refrigerant leaks
4. Filter inspection and replacement
5. Static pressure measurement across the air handler using a Testo 510 manometer
6. Superheat and subcooling measurement against nameplate specification — verifies refrigerant charge status
7. Temperature split measurement across the evaporator coil (typically 15–22°F drop between return and supply)
8. Dual-run and start capacitor microfarad measurement against nameplate rating using Fieldpiece capacitance meter
9. Contactor inspection — pitting on contacts, coil resistance measurement
10. Compressor amperage verification against nameplate FLA and LRA
11. Condenser fan motor amperage verification against nameplate FLA
12. Condensate drain flush and float switch verification
13. Refrigerant line insulation inspection
14. Thermostat calibration and control voltage verification
15. Written tune-up report with measurements documented

Heat Pump Tune-Up (Twice Annually)

Heat pump systems require service twice per year because they operate in both heating and cooling modes. Spring tune-up focuses on cooling mode (superheat/subcooling, temperature split, capacitors, contactor, condenser fan). Fall tune-up focuses on heating mode (defrost cycle verification, reversing valve operation, auxiliary strip heat function, low-ambient performance). Priority Maintenance Plan enrollment includes both tune-ups for heat pump systems.

Boiler Tune-Up

Hydronic boiler tune-ups add water quality testing and system pressure verification to the furnace-style diagnostic protocol. Cast iron sectional boilers benefit from annual sediment flush; wall-hung modulating condensing boilers benefit from annual heat exchanger inspection through service access panels and communicating control diagnostic readout. Water quality testing includes pH, hardness, and inhibitor level.

Documented Measurements

All tune-up measurements upload to the customer’s ServiceTitan record, providing trend data over years of service. This documentation:

• Establishes objective equipment condition baseline that can be compared year-over-year
• Identifies gradual degradation that isn’t visible in single measurements (manifold pressure creeping outside specification, refrigerant charge drift, capacitor value degradation)
• Supports warranty claims by documenting proper maintenance
• Transfers with the property when the home is sold, providing evidence of maintenance history to new homeowner
• Records efficiency indicators that guide replacement timing decisions

Frequently Asked Questions

How long does an HVAC tune-up take?

Furnace tune-up on well-maintained equipment typically 60–90 minutes. AC tune-up 60–90 minutes. Heat pump tune-up 90–120 minutes (both operating modes verified). Boiler tune-up 90–120 minutes including water quality testing. Tune-ups that identify problems requiring diagnostic mode take longer and typically produce specific repair recommendations. Priority Maintenance Plan tune-ups are scheduled for the full time budget so unexpected findings don’t compress the visit.

What does a tune-up cost?

Standalone furnace tune-up: $145–$225. Standalone AC tune-up: $145–$225. Standalone heat pump service (single mode): $185–$285. Boiler tune-up including water quality testing: $185–$285. Priority Maintenance Plan bundling annual furnace + annual AC + priority dispatch + waived after-hours fees + 15% repair discount: $185–$285 annual, which typically pays for itself in dispatch fee savings alone if any emergency dispatch is needed during the year.

What if the tune-up finds a problem?

Technician documents the finding, provides a repair quote, and the customer decides whether to authorize the repair. Common findings that get repaired on the same visit: flame sensor cleaning, capacitor replacement, filter cabinet reinstallation, condensate line flushing. Common findings that require separate scheduling: gas valve replacement (may need parts ordering), heat exchanger warranty coordination, major control board work. All repair authorizations are optional; the tune-up is complete regardless of whether additional repairs are authorized.

Do I need a tune-up if my equipment is running fine?

Yes. Equipment “running fine” from the homeowner’s perspective often masks issues that measurement reveals: manifold pressure drift causing 10–25% efficiency loss, static pressure elevation stressing the blower motor, refrigerant charge outside nameplate specification, gradual heat exchanger degradation. These issues don’t produce comfort complaints or equipment failures until they reach critical thresholds — often at the worst possible time (arctic outbreak or heat wave). Annual measurement catches these before critical failure, extending equipment service life and preventing emergency dispatch. It’s also required to maintain most manufacturer warranties.

Does PolarCore work on all HVAC equipment brands?

Yes. PolarCore services all major residential and light-commercial HVAC equipment brands including Trane, Carrier, Lennox, Rheem, Ruud, Bryant, Bosch, Payne, Goodman, Amana, York, Coleman, Heil, Tempstar, Comfortmaker, Weatherking, Ducane, Mitsubishi (heat pumps), Viessmann and Buderus (boilers), and more. Universal-fit replacement parts cover most tune-up-identified repair scenarios regardless of brand. Manufacturer-specific parts are typically available within 1–3 business days from regional distributors when specialty components are required.
