HOME / AC SERVICES / AC REPLACEMENT
AC replacement should start with the home's cooling and moisture-removal needs, not with the tonnage printed on the old unit. Blast Mechanical evaluates residential central AC and heat-pump options for Southeast Texas homes, explains the matched indoor and outdoor equipment, and provides a written system quote before installation is authorized.
Replacement deserves consideration when a major repair is combined with declining performance, repeated failures, refrigerant leaks, mismatched components, poor humidity control, or equipment that no longer meets the home's needs. Age matters, but condition, repair cost, comfort, refrigerant type, efficiency, and remaining component compatibility matter too.
SEER2 describes seasonal cooling efficiency, while EER2 describes performance at a specific high-temperature test condition. Single-stage, two-stage, and variable-capacity describe how the equipment adjusts output. A heat pump provides cooling and heating; a straight-cool system provides cooling and is paired with a separate heating source. The proposed outdoor unit, indoor coil or air handler, metering device, thermostat, and approved refrigerant must work as a compatible system.
A major failure on an older or poorly performing system may make replacement sensible, but age alone is not enough. Compare the repair, overall equipment condition, refrigerant type, comfort history, efficiency, and expected remaining service life before deciding.
Timing depends on the system type, equipment location, duct or electrical corrections, permits, inspections, and equipment availability. The written quote should state the expected schedule for that specific installation.
Yes. Proper sizing considers construction, insulation, windows, orientation, infiltration, duct location, internal loads, and local design conditions. Square footage and the old equipment label are not enough by themselves.
Many current residential systems use lower-GWP refrigerants such as R-32 or R-454B. The exact refrigerant is determined by the selected equipment. Components and refrigerants are not interchangeable, so the proposal should identify the complete matched system.
