“Our water heater died on a Sunday. APEX was at the door in under two hours, had a new unit installed the same afternoon, and the price matched the quote exactly. Zero surprises.”
“Replaced our old central AC with a Mitsubishi ductless system in our 1920s home. Clean install, respectful of the property, and our electric bill dropped 30% the first month.”
“Commercial property manager here — APEX handles our whole portfolio now. Fast, licensed, and their invoicing is clean. Can’t recommend them enough.”
A standard 50-gallon gas tank install typically runs $2,200–$3,400 turnkey; tankless installs $4,500–$7,500 depending on sizing and gas/vent work. Every quote is flat-rate and in writing before we begin.
It depends on your household size, hot-water usage, gas supply, and budget. Tankless lasts longer and saves on standby losses; tanks are cheaper up front. We’ll walk you through both on your free estimate.
