“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.”
Yes — modern cold-climate heat pumps (like Mitsubishi Hyper-Heat) produce full heating capacity down to -13°F. They easily handle New England winters and often replace oil or propane heat entirely.
Depends on square footage and layout. A typical 2,000 sq ft colonial runs 3–4 zones; a ranch with open living may only need 2. We do a free in-home assessment and design.
Not with our installs. We plan line-set routing carefully, use low-profile or ceiling-cassette heads where appropriate, and always color-match covers. Most clients are surprised how unobtrusive they are.
Most whole-home Fairfield County installs land between $14,000–$28,000 depending on zones and equipment — before the CT rebates and federal tax credit, which typically cover 20–40%.
