American Standard Central Heat Pump Installation for a Ranch-Style Home in Pinole
Completed July 23, 2026
Upgraded a 2,300-square-foot ranch-style home with an American Standard 4-ton inverter heat pump and matching horizontal evaporator coil. The project included a Nest WiFi thermostat, enlarged return filter grille, new refrigerant line set, and electrical and attic installation improvements.
Galaxy Heating & Air Conditioning installed an American Standard central heat pump system at a 2,300-square-foot ranch-style home. The homeowner had central HVAC with gas heating and wanted to transition to heat pump heating and cooling.
The project included a 4-ton American Standard inverter heat pump, model 5A6H7048A1000, and a matching horizontal evaporator coil. The selected outdoor unit was listed at 17.2 SEER2. Its variable-speed inverter operation allows output to adjust to changing demand, supporting more consistent indoor temperatures. A Nest WiFi thermostat provided updated system controls.
We enlarged the return air filter grille to 30 × 20 inches and provided a new filter while reusing the existing return duct. In the attic, the scope included extending the equipment platform, installing a new safety drain pan, and connecting the drain line to the existing condensate pump.
Outdoor work included a vibration-isolation pad and leveling and securing the heat pump. We also installed a new electrical supply from the panel, an outdoor disconnect and electrical whip, and a new refrigerant line set with control wiring and protective line set cover. Refrigerant piping work included brazing, nitrogen pressure testing, and evacuation.
Permits and Title 24 compliance work were included in the project scope. Warranty coverage included a five-year Galaxy labor warranty and ten-year manufacturer parts and compressor warranties, subject to applicable terms. The existing furnace was excluded from the new warranty coverage.
Project details
Customer problem
The homeowner wanted to upgrade the central HVAC system in a 2,300-square-foot ranch-style home from gas-based heating to a central heat pump solution, while continuing to use a ducted system to serve the home.
Previous system
An existing central ducted HVAC system with a gas furnace. The installation scope retained the existing return duct and condensate pump and did not include a replacement furnace.
Recommendation and why
We recommended an American Standard 4-ton inverter heat pump with a matching horizontal evaporator coil to introduce heat pump heating and cooling into the home’s central ducted system.
The inverter design allows the heat pump to adjust its output as demand changes. The recommendation also addressed installation needs beyond the outdoor equipment: a larger return filter grille, an extended attic platform, a new safety drain pan, new refrigerant piping, and a dedicated electrical supply.
A Nest WiFi thermostat added convenient temperature control and remote access. Together, these improvements supported the homeowner’s goal of upgrading to central heat pump operation.
