The cost to install a new AC and furnace with Moffett Plumbing & Air is set by a straightforward quote after an in‑home assessment, because price depends on your home and the system you choose. The biggest drivers are the size of the space and whether you select central AC with a gas furnace or a heat pump solution, along with efficiency ratings. We design the system after evaluating your home’s size, insulation, and comfort goals, then install to manufacturer specs and complete a quality check and walk‑through. Our team regularly installs HVAC systems across Orange County, including work near Placentia, bringing local know‑how to site placement and duct details. One thing we see a lot: right‑sizing equipment often lowers total cost of ownership more than chasing the highest tonnage.
When we price your project, we consider:
- Home size and insulation level
- System type (central AC + furnace, heat pump, or ductless)
- Efficiency rating and thermostat/IAQ add‑ons
- Ductwork condition or changes needed
Schedule an assessment so we can size the system correctly and confirm duct needs before giving you the exact price.
