Frequently Asked Questions About Brooklyn HVAC Service
Common questions from Brooklyn homeowners and businesses
Do you handle commercial HVAC in Brooklyn?
Yes — commercial HVAC is a core part of our business. We install, repair, and maintain rooftop units, VRF systems, commercial boilers, and kitchen ventilation for Brooklyn offices, restaurants, retail spaces, and mixed-use buildings. We also offer commercial maintenance contracts with priority scheduling.
How quickly can you respond to an HVAC emergency in Brooklyn?
Most emergency calls in Brooklyn are answered within 60 minutes — for both homes and businesses. Our technicians are dispatched across all Brooklyn neighborhoods around the clock.
Do you service Brooklyn brownstones?
Absolutely. Brooklyn brownstones are our specialty. Most lack ductwork, making ductless mini-splits the ideal choice for cooling. For heating, we service and upgrade existing boiler/radiator systems. We preserve your brownstone's character while adding modern comfort.
What does a new AC installation cost in Brooklyn?
A central AC install for a typical Brooklyn home runs between $4,500 and $9,000 depending on size and ductwork. Ductless mini-split systems start around $3,200. Commercial installations vary by scope — we provide free on-site estimates with transparent pricing.
Are you licensed and insured for commercial and residential work?
Fully licensed by the NYC Department of Buildings and insured for residential and commercial HVAC work. EPA certified for refrigerant handling. We're familiar with Brooklyn building codes, landmark restrictions, and co-op/condo regulations.
