HVAC Contractor in Queens, NY — Heating & Cooling Done Right

We provide 24/7 emergency HVAC service, repair, installation, replacement, and maintenance. That covers central air conditioning, heat pumps, ductless mini-splits, furnaces, boilers, rooftop units, ventilation, ductwork, thermostats, condensate systems, indoor air quality, and commercial HVAC across Queens and the wider NYC metro.

As a planning range, emergency HVAC repair typically runs about $325–$1,550, AC repair about $200–$850, furnace repair about $200–$900, and boiler repair about $250–$1,175. These are non-binding estimates — your final price depends on the diagnosis, parts, labor, access, urgency, and any permits.

Research places a full HVAC installation at roughly $5,800–$20,500 and a full-system replacement around $9,800–$18,200. Heat-pump installation runs about $7,800–$23,400 and boiler installation about $7,800–$18,200. These are planning ranges, not quotes — ask for a line-by-line scope covering equipment, permits, access, and startup.

Yes. J&S HVAC Expert answers emergency calls around the clock for no heat, no cooling, active leaks, frozen coils, and boiler failures. If you smell gas or see smoke or sparking, leave the area and call your utility or 911 first, then call us for dispatch.

Call promptly for a gas odor, smoke, sparks, exposed wiring, an active water leak, a frozen building during a cold snap, or loss of cooling during dangerous heat. For any immediate danger, leave the area and contact the appropriate emergency service first. Never repeatedly reset a system when the same safety fault keeps returning.

Turn the system off if it's safe to reach the switch, contain the water, and photograph the equipment and affected surfaces before cleanup. A blocked condensate drain or frozen coil is often involved. Begin drying promptly — the EPA recommends drying wet materials within 24–48 hours — then call us for diagnosis.

NYC requires a DCWP Home Improvement Contractor license for applicable residential work over $200, and we work within NYC DOB permit requirements.

Yes. NYC requires a DCWP Home Improvement Contractor license for applicable residential home-improvement work over $200, including central-air or heating installation.

A good estimate identifies the equipment, capacity, and efficiency; labor and parts; any ductwork, line-set, electrical, or venting work; refrigerant handling; permits; roof, crane, elevator, or delivery assumptions; disposal; startup testing; cleanup; warranties; and payment milestones. It should also state exclusions and the change-order process — not just one headline number.

Yes. J&S HVAC Expert is a bilingual company. Our team communicates clearly in English and Spanish so every homeowner, tenant, co-op board, and property manager fully understands the diagnosis, the options, and the written estimate before any work begins.

Weigh age, repair history, parts availability, efficiency, comfort, safety, and total installed cost. When there's no immediate safety issue, ask for a written diagnosis and at least two line-by-line proposals. Repair often makes sense when the failure is clearly defined and the system is otherwise reliable.

Yes. We document observable equipment and water-damage facts — photos, model and serial numbers, written diagnostic findings, estimates, invoices, and dates — so you have a clear file. Your insurer and adjuster decide coverage; the EPA recommends drying wet materials within 24–48 hours.

We serve Queens and the surrounding NYC metro, including Brooklyn, Manhattan, the Bronx, and Staten Island, plus Nassau County, Suffolk County on Long Island, and Westchester County. Call us to confirm same-day availability for your specific neighborhood.
