When your heating stops working in January or your AC fails in August, the last thing you need is a Long Island company estimating a two-hour drive, a national hotline with a four-hour window, or a contractor who handles water heaters between drain jobs and does not know what system you have until they walk in the door.
Forest Hills HVAC & Air Conditioning is Queens-based. Our technicians work in Jamaica regularly. We provide heating, air conditioning, and plumbing service throughout Jamaica, NY — zip codes 11432, 11433, 11434, 11435, and 11436 — with NYC-licensed technicians, 24/7 emergency response, a written flat-rate price before any work begins, and no after-hours surcharge on any call.
No heat when outdoor temperatures are at or below freezing. Under New York City law, building owners must maintain indoor temperatures of at least 68°F between 6am and 10pm from October 1 through May 31 when outdoor temperatures drop below 55°F. A heating failure during this period is both a comfort emergency and a legal compliance issue. We treat every no-heat call as a priority dispatch — no voicemail, no callback queue.
Gas smell near your furnace, boiler, or water heater. Leave the area immediately, do not operate any switches, call 911 and Con Edison first — then us. This is a life-safety situation above all else.
Carbon monoxide alarm triggered. Evacuate and call 911. Once emergency services clear the property, call us to identify the source — cracked heat exchanger, blocked flue, or incomplete combustion.
Active water leak from any appliance or pipe. Water spreads fast. An hour of delay is flooring damage, drywall damage, and mold risk.
Complete AC failure during a heat advisory. NYC heat events are a health emergency. We dispatch immediately throughout Jamaica — no after-hours surcharge, no wait until the next available appointment.
Burning smell from any HVAC unit. Shut the system off at the thermostat and breaker immediately. A burning smell indicates an electrical failure with fire risk.
Jamaica is one of the most housing-diverse neighborhoods in Queens. A single block in Jamaica Estates might have a 1920s brick home on a one-pipe steam system sitting next to a 1970s colonial on a forced-air gas furnace sitting next to a newer construction on a heat pump. Every system heats differently, fails differently, and requires different parts and expertise.
Most HVAC companies dispatched from outside Queens arrive without knowing which system they are about to work on. We service every heating system configuration found in Jamaica homes — steam boilers, hot water boilers, gas and oil furnaces, heat pumps, and electric baseboard systems — with parts for all of them on every truck.
Jamaica summers are brutal. The combination of Queens heat and high humidity pushes cooling systems to their operating limits from July through August. When your AC fails during a heat advisory, every hour matters.
AC running but producing warm air.
Refrigerant has depleted below operating level from a leak. The compressor and fan run — the system appears to be working — but it cannot transfer heat without adequate refrigerant charge. We find the leak, repair it, and recharge. A recharge without fixing the leak depletes again within weeks. → View AC repair service
AC completely unresponsive.
A failed capacitor stops the compressor and condenser fan simultaneously. Same-visit replacement in most cases. A breaker that will not reset indicates an underlying electrical fault that needs diagnosis first. We determine which situation you are in before touching anything. → View AC repair service
AC freezing up — ice on the lines or unit.
Shut the system off immediately if you see ice. Running a frozen system damages the compressor. The cause is restricted airflow from a severely clogged filter or failing blower motor — or low refrigerant charge. → View AC repair service
Ductless mini split not cooling or throwing error codes.
Error codes identify the failure precisely — refrigerant pressure fault, thermistor failure, communication error, drain pan overflow. We diagnose from the code, confirm with instruments, and repair the same visit in most cases. → View mini split repair service
Emergency AC replacement.
Compressor failed on a unit over 12 years old, or system uses R-22 refrigerant — replacement is the right call. We carry units on every truck and complete most emergency replacements the same day. → View AC replacement · View emergency AC repair
Steam boiler — no heat or uneven heat.
Steam boilers are the dominant heating system in Jamaica's pre-war and older two-family homes. When a steam boiler stops heating — or heats some rooms but not others — the cause is almost always a failed low-water cutoff, clogged steam traps preventing condensate from returning, failed main vents slowing steam distribution, or pressure control failure causing the boiler to cycle off early. Water hammer — the banging and clanking in steam pipes — is caused by condensate not returning properly. All of these are diagnosable and repairable the same visit. A steam boiler not producing heat is almost never a boiler that needs full replacement. → View boiler repair service
Hot water boiler — no heat or cold zones.
Hot water boilers with baseboard radiation are common in Jamaica's post-war and renovated properties. Circulator pump failure, zone valve failure, waterlogged expansion tank, and air-locked distribution lines are the most frequent causes of heat loss. All are same-visit repairs in most cases. → View boiler repair service
Gas furnace — not firing or blowing cold air.
A furnace that will not fire is almost always an ignition failure — burned-out hot surface igniter, failed flame sensor shutting the gas valve off as a safety response, or a pressure switch not detecting proper draft. A furnace running but producing cold air has tripped its limit switch due to restricted airflow, has a failed gas valve, or — most seriously — has a cracked heat exchanger creating a carbon monoxide risk. We identify which cause is present before recommending any action. → View furnace repair service
Oil furnace — lockout or no ignition.
Oil-fired systems in Jamaica's older housing stock have their own failure language — nozzle wear, pump failures, clogged fuel filters, and burner lockouts that repeat until the root cause is found. We carry oil furnace components and handle these calls with the same urgency as gas system emergencies. → View furnace repair service
Heat pump not heating in cold weather.
Standard heat pumps lose heating capacity below 35°F. If yours is running but not warming the space in winter, the reversing valve may have failed, refrigerant charge may be low, or the system may be undersized for cold-climate operation. We diagnose which and give you a real repair versus replacement assessment with actual numbers. → View heat pump repair service
Emergency boiler or furnace replacement.
When a system is beyond repair — cracked boiler sections, seized compressor on a heat pump, failed heat exchanger — we replace it the same day in most cases. NYC permit and old unit disposal included. → View furnace replacement · View boiler replacement · View emergency heating repair
No hot water.
Electric unit — burned-out heating element. Gas unit — failed thermocouple or gas valve. Both are same-visit repairs. We confirm the cause before quoting anything. → View water heater repair
Water heater leaking.
Leak from a fitting or valve — repairable same day. Leak from the tank body itself — the tank has corroded internally and will fail completely. We replace it the same day with NYC permit included. → View water heater repair · View water heater replacement
Burst pipe or active water leak.
Dispatched immediately. Locate, isolate, and repair the same visit. → View pipe repair service
Sewer backup.
Health hazard and property damage emergency. We clear the blockage and identify whether it is isolated or a sign of a deeper line failure. → View sewer line repair · View emergency plumbing
Jamaica is the transportation and commercial hub of southeast Queens. Jamaica Avenue, Sutphin Boulevard, and the Jamaica Center corridor serve as major commercial arteries with a high concentration of mixed-use buildings, retail properties, and multi-family housing that run commercial HVAC configurations — packaged rooftop units, VRF multi-zone systems, and commercial boilers — alongside residential systems. A complete rooftop unit failure on Jamaica Avenue affects a business's ability to operate, not just its occupants' comfort.
We provide the same emergency response for commercial HVAC failures in Jamaica as we do for residential — 24/7, same-day, with technicians trained on commercial packaged units and VRF systems that most residential HVAC companies cannot service. → View commercial HVAC service · View packaged unit repair
Jamaica also has a significant concentration of two-family and three-family homes — a housing type where a heating or plumbing failure affects multiple households simultaneously and creates pressure for faster resolution than a single-family call. We understand this and dispatch with that urgency.
AC maintenance — before summer pushes your system to its limit. → View AC maintenance
Heating maintenance — annual boiler and furnace service before winter. Heat exchanger inspection, combustion analysis, and safety device testing included. → View heating maintenance
Ductless mini split installation — single and multi-zone systems for Jamaica homes and apartments without ductwork. Sized for Queens winter temperatures. NYC permit included. → View mini split installation
Boiler installation — sized for your building's radiation load, NYC permit included. → View boiler installation
Furnace installation — Manual J load calculation completed before any equipment is recommended. → View furnace installation
Heat pump installation — hyper-heat models for primary heating in Jamaica homes without gas access or seeking to reduce fuel costs. → View heat pump installation
Tankless water heater installation — endless hot water, 30–40% lower energy costs, 30% federal tax credit up to $2,000 on qualifying units in 2026. → View tankless installation

No after-hours surcharge — ever. Every competitor serving Jamaica either charges a premium for evening, weekend, and holiday calls or does not answer at all. Our flat-rate price does not change based on when you call. A midnight emergency costs the same as a noon appointment.
Queens-based, not Long Island. Hart Home Comfort has a 631 number. We have a Queens number and Queens-based technicians. When you call at midnight in January, the technician dispatched is minutes away — not crossing Nassau County.
Written price before we start. Complete cost — parts, labor, permit — before we open a single tool. No diagnostic fee followed by a separate quote once the system is already open. The number you approve is the number on your invoice.
Every system type covered. Steam boilers, hot water boilers, oil furnaces, gas furnaces, heat pumps, central AC, ductless mini splits, commercial HVAC, VRF systems, and full plumbing. One call, one company, everything covered.
NYC permit on every job that requires one. Every HVAC installation and water heater replacement requires a DOB permit. We file it, schedule the inspection, and get the sign-off — included in your price.
NYC licensed on every job. Every technician holds the required New York City HVAC certification. Every plumber is a licensed NYC Master Plumber.
