Multi-zone central air, heat pumps, and full-system replacements for Old Westbury’s larger homes. Right-sized equipment, written quotes, rebates handled.
Book a Free AssessmentOld Westbury homes are big — and big homes punish undersized or badly zoned cooling. A single-zone system fighting to cool 5,000 square feet across three floors runs constantly, costs a fortune, and still leaves bedrooms warm. We design and install multi-zone central air and variable-speed systems matched to the actual load of the house: separate zones for sleeping and living areas, capacity calculated from measurements, and equipment tiers quoted side by side so you choose the trade-off, not us.
Central air, mini-splits, and heat pumps — sized from measurements, installed in 1–2 days.
Same-day diagnosis and repair on all major brands, with upfront pricing before work starts.
Furnace and boiler repair, replacement, and 24/7 no-heat emergency response.
Larger Old Westbury properties often need what most contractors don’t bother to design: true zoning. Two or three condensers or a variable-capacity system, dampered ductwork, and independent thermostats mean the primary suite, guest wing, and main floor each hold their own temperature — without one giant unit short-cycling. We also install cold-climate heat pumps that qualify for federal tax credits and utility incentives, which on systems this size can be a five-figure difference. Paperwork included.

Multi-zone systems for larger homes vary widely with capacity, zoning, and ductwork condition — which is exactly why we quote from an on-site assessment, itemized, with options at different tiers. The assessment and the written quote are free.
Yes — cold-climate heat pumps handle Long Island winters and unlock federal tax credits plus utility incentives. On estate-sized systems those incentives are substantial, and we identify every one you qualify for in the quote.
Yes. Permits and inspections are part of every installation we do — included in the quote, never an add-on.
