Seasonal start-up and tune-up
Get the system checked before the first hot or cold week hits. We do a full system inspection, replace the filter, clean and tune the equipment, and tell you honestly what shape it's in. If something needs attention, you'll get a price before we touch it.
Repairs, replacements and maintenance for every kind of system
Homes, restaurants, bars and small commercial buildings. If it heats, cools or keeps something cold on Long Island or in the city, we've probably worked on it.
-
Heating Furnaces · Boilers · Heat pumps
No-heat calls, short cycling, cold rooms, pilot and ignition problems. We repair what's fixable and give you a straight answer when a replacement makes more sense than another repair.
Gas and oil furnaces, hot-water and steam boilers, heat pump systems.
-
Air conditioning Central air · Condensers
Systems that run but don't cool, frozen coils, refrigerant leaks, failed capacitors and compressors. Full condenser and air-handler replacements sized for your house, not a guess.

Maintenance plans Spring & fall
A tune-up before each season catches the small stuff before it becomes a July breakdown. Filter changes, coil cleaning, electrical checks and a written note of anything to keep an eye on.
Ask about a yearly plan when you call.
-
Emergency repair Nights & weekends
Heat out in January or AC dead in a heat wave doesn't wait for Monday. Call the emergency line and we'll get someone out as fast as we can.

Every review we have is on Google, where we can't edit or filter them. The two things people mention most are fair pricing and quality work. Read them all, and if we've done a job for you, we'd appreciate a review of your own.
A local heating and cooling company, not a call center
J.R. Mechanical has been keeping homes and businesses comfortable across Long Island and New York City for more than fifteen years.
We keep it simple. You call, you get a person, and you get honest answers. Our technicians are EPA certified, the company is fully licensed and insured, and we price the job up front so you can decide without pressure. Most of our work comes from customers who call us back and from neighbors they send our way.
We work on residential systems of every age and on the commercial side too. For restaurants and bars that means walk-in coolers, ice machines and reach-ins as well as the HVAC, because when the walk-in dies on a Friday night you need one number to call, not three.
