“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.”
We’re factory-trained on Mitsubishi, Daikin, Carrier, Trane, Lennox, and Rheem. We’ll recommend the right system for your home’s size, insulation, and budget — not just the brand with the biggest incentive.
