Typically yes with Power Management modules that stagger compressor starts. Three condensers usually push you to a 36kW unit in Springfield, Illinois climates.
+How long does a whole-house generator install take in Springfield, Illinois?
Permit + utility coordination is usually 2–4 weeks. On-site install in Springfield, Illinois is typically 1–2 days for the pad, gas, ATS, and panel work, plus a commissioning visit.
