What determines the correct AC size for a home?

Cooling load calculation accounts for insulated ceiling area, wall exposure, window placement and type, infiltration rates through doors and penetrations, and internal heat generation from occupants and appliances. These factors are measured and totaled to determine tonnage, which is then matched to equipment that operates efficiently at that load.

How does ductwork condition affect a new AC installation?

Leaky or undersized ducts reduce airflow to living spaces and force the system to work harder than necessary. If existing ducts can't deliver the new equipment's designed airflow volume, sealing or resizing becomes part of the installation to prevent performance loss.

When should I replace an AC system rather than continue repairing it?

If your current equipment is over 12 years old, requires refrigerant that's no longer manufactured, or needs a second major component repair within a year, replacement typically becomes more practical than investing in aging infrastructure that will continue to degrade.

What happens during the installation process from start to finish?

The existing system is disconnected and removed, the new indoor and outdoor units are positioned and secured, refrigerant lines are connected and pressure-tested, electrical circuits are verified for proper voltage and amperage, and the system is charged with refrigerant according to manufacturer specifications before final testing confirms operation.

Why does Amarillo's climate affect equipment selection decisions?

Extended periods above 95 degrees mean the system operates at peak capacity for weeks at a time, which requires components rated for continuous-duty cycles and refrigerant charges calibrated for high ambient temperatures. Equipment selected for milder climates may struggle under sustained Panhandle heat.

AC Installation and Replacement

Properly planned cooling begins with evaluating the complete system—existing ductwork condition, home layout, insulation levels, and current equipment performance—rather than treating replacement as a straightforward swap. Amarillo Pro-Air handles AC installation and replacement in Amarillo for homeowners facing aging equipment that no longer maintains consistent temperatures or requires frequent repair. The process accounts for the home's actual cooling load, which varies based on square footage, window orientation, insulation quality, and how many occupants generate heat during the day.

Installation decisions depend on whether the existing duct system can support the new equipment's airflow requirements, whether the electrical service panel has capacity for the selected unit, and whether the outdoor placement allows adequate clearance for airflow and service access. A system that's undersized runs continuously without reaching set temperature, while an oversized unit short-cycles and fails to dehumidify properly. Load calculation determines the correct tonnage based on measured variables rather than assumptions.

Request an evaluation that includes duct inspection and load analysis before committing to a replacement system.

The evaluation measures duct leakage rates, insulation R-values, window solar gain, and current airflow distribution to calculate the home's peak cooling demand. This data determines the appropriate equipment size and whether duct modifications are needed to handle the new system's airflow volume. Electrical requirements are verified against the home's service panel capacity, and outdoor unit placement is assessed for drainage, vibration control, and service clearance.

After installation, you'll notice the system reaches your set temperature without running constantly, humidity levels stabilize as the unit completes full cycles, and air distribution becomes more even across rooms that previously felt warmer or cooler than others. The outdoor unit sits level on a stable pad, refrigerant lines are insulated to prevent condensation, and the thermostat communicates accurately with the new equipment. Startup testing confirms refrigerant charge, electrical draw, and airflow rates match manufacturer specifications.

Installation includes connecting the new equipment to existing ductwork or modifying ducts if the airflow requirements have changed. The work also addresses condensate drainage, which must slope continuously away from the indoor unit, and verifies that the outdoor disconnect and electrical circuit match the new system's amperage draw. Some installations require panel upgrades if the existing electrical service can't support the added load.
