We install replacement equipment from Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and American Standard. Heat pump conversions most commonly use Carrier, Trane, or Lennox in the right capacity for the home. On the indoor side, matched coils and air handlers from the same manufacturer protect the warranty and the AHRI-rated efficiency number. Mixing a Carrier outdoor with a Goodman indoor saves money on paper but voids the matched-system efficiency rating and often the warranty.
Our replacement work follows ACCA Manual J for the load calculation, ACCA Manual S for the equipment selection, and EPA Section 608 for the refrigerant recovery and handling. New equipment installed in 2025 and later runs the R-454B refrigerant per the EPA transition. Older R-410A equipment is still installable through existing supply chain, but most new installs from this point forward use R-454B. We carry the right gauges and certifications for both.
On the tooling side, every replacement crew runs digital recovery scales, vacuum micron gauges, and the same start-up instrumentation we use on new installs. Refrigerant charge is verified by subcooling against the manufacturer's data plate, not by gauge pressure alone. Static pressure across the air handler is measured and documented. Where the line set is reused, we triple-evacuate to make sure no residual oil from the old refrigerant remains in the lines.
