Restoring Lost Cooling Power in an Aging System
Output restoration is for a system that used to cool your home fine and has gradually lost that capacity over time, not a system that was ever undersized. This is the most common pattern we see in systems 8-15 years old that have gone without regular maintenance: gradually declining performance that homeowners often attribute to 'it's just getting old' when the real causes are usually fixable.
Georgetown's pollen season, particularly the heavy cedar pollen from December through February, contributes to coil fouling faster than in many other regions. A coil that would stay reasonably clean for two years in a low-pollen climate can build up meaningfully faster here, which is part of why output restoration is a more common call in Central Texas than elsewhere.
Signs of Gradual Output Loss
- The system used to keep the house comfortably cool and now runs longer to achieve the same result
- You've noticed the decline happen gradually over a year or more, not suddenly
- The coils haven't been professionally cleaned in the system's lifetime
- You suspect a slow refrigerant leak but haven't had it confirmed
- The system is old enough to have real wear but young enough that replacement doesn't feel justified yet
How We Restore Output
We check the three biggest causes of gradual output loss in order: coil condition (a dirty evaporator or condenser coil is like a layer of insulation blocking heat transfer), refrigerant charge (a slow leak can drop charge over months or years without a sudden failure), and compressor health (measured through amperage draw compared to the nameplate rating).
Coil cleaning and refrigerant correction restore most of the lost output on systems where the compressor is still healthy. If compressor wear is the limiting factor, we'll tell you honestly what kind of improvement to expect and whether that repair is worth it relative to the system's remaining life.
We also check the blower motor's amperage draw against its nameplate rating during this process, since a motor working harder than it should to move the same air is an early warning sign worth catching before it fails outright.
