Staten Island's 24/7 Heating & Cooling Team
EM Mechanical NY LLC is a licensed, insured HVAC contractor based in Mariners Harbor — serving Staten Island, Brooklyn & surrounding areas within 30 miles with honest diagnostics and free, written estimates.
An HVAC contractor that measures before it quotes
EM Mechanical NY LLC is owned and run by Enrique Martínez, and works out of a shop in Mariners Harbor on Staten Island. That location matters more than it sounds: when a furnace quits in January or a compressor fails in July, we are already on the island rather than routing a technician in from another county.
We handle heating and cooling under one roof — furnaces, steam and hot-water boilers, central air, heat pumps, ductless mini-splits, thermostats, and ductwork. Homeowners here should not have to keep one contractor for the winter problem and a different one for the summer problem.
The part of the work we take most seriously is the diagnosis. Plenty of HVAC failures get "fixed" by swapping parts until something changes, and the customer pays for every guess. We test refrigerant pressures, electrical draw, airflow, combustion, and temperature rise first, so the repair addresses what actually broke.
Every job starts with a free, written estimate you approve before work begins, and ends with measured readings proving the system performs. When replacement genuinely beats repair, we show you the numbers for both and tell you which one we would choose ourselves — including when that is the cheaper one.
What we hold ourselves to
Six habits that apply to a $200 capacitor swap and a full system replacement alike.
Diagnose Before Quoting
Pressures, temperature split, and combustion get measured — so you pay to fix the real fault, not a guess.
Plain-English Answers
You hear what failed, why it failed, and what the options cost, without the jargon or the pressure.
Respect for Your Home
Drop cloths, shoe covers, and a clean work area. The basement looks the way we found it.
Answering at 2 A.M.
Genuine round-the-clock dispatch. A no-heat call in January reaches a person, not a voicemail box.
The Price We Quoted
Written, itemized, approved before work starts — and it does not grow once the job is underway.
Verified Before We Leave
Every job closes with performance readings proving the system genuinely heats or cools as it should.
Four steps from first call to verified fix
A predictable process, so you always know what happens next.
You Call
Describe the symptoms. We schedule you — including nights, weekends, and holidays.
We Diagnose
A full test of the system finds the actual cause, then you get a written, itemized price.
We Repair
Trucks carry the common failure parts, so most jobs are finished in a single visit.
We Verify
Measured readings confirm the system works before we pack up and clean the area.
