21-Point Clinical Maintenance.

Preventative maintenance is the single highest-ROI investment you can make in your HVAC system. A system that receives annual clinical maintenance will last 15-20 years. A neglected system will fail in 8-10. At Aurora HVAC Services, our maintenance protocol is not a quick filter change and a handshake. It is a 21-point forensic audit of your entire mechanical system.

The 21-Point Protocol.

Our maintenance protocol begins outdoors. We chemically foam the condenser coil to dissolve the insulating layer of pollen, grass clippings, and cottonwood that dramatically reduces heat rejection efficiency. We test the run capacitor under load, measure compressor amp draw against the RLA (Rated Load Amperage) on the data plate, and inspect the contactor for pitted or burnt contact points. Moving indoors, we inspect the evaporator coil for biological growth, test the blower motor's amp draw and RPM, and measure Total External Static Pressure across the air handler. We pull and inspect the air filter, check the condensate drain for blockages (a leading cause of water damage), and test the thermostat's calibration against an independent temperature sensor.

The Cost of Neglect.

A dirty condenser coil forces the compressor to work significantly harder to reject heat, increasing electrical consumption by 20-30% and driving up discharge pressures. High discharge pressure superheats the compressor oil, breaking down its viscosity and reducing its ability to lubricate the internal scroll mechanism. This is the beginning of compressor death. Similarly, a dry condensate trap will expose your home to sewer gas, and a cracked condensate pan will dump gallons of water into your ceiling. Our clinical audit catches these failures months before they become catastrophic emergencies.

Seasonal Maintenance Plans.

We recommend biannual maintenance: a cooling-focused audit in spring (March-April) and a heating-focused audit in fall (September-October). Our service agreements include priority scheduling, discounted diagnostic fees, and written reports of all findings. For Aurora homeowners, this is the most cost-effective way to protect the $5,000-$15,000 investment sitting in your basement and backyard.
