We repair central air conditioning systems — the ducted split systems that cool most houses and townhouses in Queens, Staten Island, Brooklyn and Nassau County: an outdoor condenser unit connected to an indoor air handler or a coil on the furnace, moving cooled air through ducts. HVAC diagnostics are $99 + tax, credited in full toward your approved repair. You approve a fixed repair price before work begins, and every repair is backed by our 90-day labor warranty.
Not sure what you have? If one outdoor unit cools the whole home through vents in every room, that is a central AC. Individual wall units are ductless mini-splits, and through-wall units in apartment buildings are PTAC or water-source systems — we repair those too, on their own service pages.
Common Central AC Problems We Repair
The system does not cool; it cools some rooms but not others; the outdoor unit runs but the air stays warm; the system short-cycles; ice forms on the refrigerant lines or the indoor coil; water leaks near the air handler; the outdoor fan or compressor does not start; the electric bill jumps without better cooling. The same symptom can come from a refrigerant leak, a failing capacitor, a dirty or frozen coil, a blower problem, a clogged condensate drain or a control fault — so we diagnose before quoting, and we do not replace parts on a guess.
How Central AC Diagnostics Work
We test the full cooling sequence: thermostat call for cooling, airflow and filter condition, evaporator and condenser coil condition, refrigerant pressures with superheat and subcooling readings, capacitor and contactor, compressor amp draw, blower motor operation, condensate drain condition, and duct connections at the air handler. HVAC diagnostics are $99 + tax, credited in full toward your approved repair. You receive an estimate with labor and parts shown separately before any repair begins.
Central AC Repairs We Perform
Capacitor and contactor replacement; condenser fan motor replacement; blower motor and capacitor replacement; refrigerant leak search, repair and recharge (refrigerant work performed under EPA Section 608 Universal certification); evaporator coil cleaning and replacement; condensate drain clearing and condensate pump replacement; control board repair and replacement; thermostat replacement and wiring repair. We work on central systems from Carrier, Lennox, Trane, Goodman, Bryant, Rheem, York and other major manufacturers.
Central AC Repair FAQ
How much does central AC repair cost?
Diagnostics are $99 + tax, credited in full toward your approved repair. The repair is quoted after diagnostics as a fixed price, with labor and parts shown separately, and starts only with your approval. Labor carries a 90-day warranty; parts are covered by the manufacturer or supplier as specified on your receipt.
Do you install and maintain central AC systems too?
Yes. Installation estimates are free, and seasonal maintenance is available — see the Air Conditioning Installation and Air Conditioning Maintenance pages on this site, or call (917) 997-4525 and describe your home and system.
My outdoor unit runs but the house stays warm. What does that usually mean?
Common causes are low refrigerant from a leak, a dirty condenser coil, a weak capacitor or failing airflow at the indoor unit. Each cause has a different fix and a different price, which is why we test first and quote a fixed price after diagnostics.
How do I book a central AC diagnostic?
Call (917) 997-4525, Monday through Friday, 10 AM to 6 PM, or use the Request Service page on this site — we reply to confirm scheduling; an online request is not a confirmed appointment.
