AC Installation & Replacement On Long Island

From a load calculation, not from the size of the old unit. That means measuring square footage, insulation, window area and orientation, ceiling heights and duct capacity. Matching whatever tonnage was there before repeats whatever mistake was made last time, and oversizing is the most common one.

No, and it is the most common installation error. An oversized system cools the air fast and shuts off before it has removed the humidity, which leaves the house cold and clammy. It also short-cycles, which wears the compressor out early. Correctly sized equipment runs longer, quieter cycles and dehumidifies properly. Getting that right is what the load calculation is for, and we do it before quoting rather than after.

Under the EPA phasedown, residential systems manufactured from 2025 onward use lower global-warming-potential refrigerants such as R-454B instead of R-410A. If your existing system uses R-410A it still works and does not need replacing early. What it does mean is that a new installation today will be on the newer refrigerant, and the two cannot be mixed.

A newer system with one failed component is usually worth repairing. Replacement generally wins when the compressor fails on an older system, when a large refrigerant leak turns up on an ageing R-22 unit, or when repairs are becoming a yearly event. We will give you both numbers rather than steering you toward the bigger job — and because we handle both, you are not getting a repair quote from someone who only sells repairs.

Yes. Ductless mini-splits cool and heat individual rooms or zones without any ductwork, which is why they suit Long Island Capes, converted attics, additions and sunrooms so well. They can be single-zone for one room or multi-zone running several indoor heads from one outdoor unit.

Yes. We pull the permits the work requires and see the inspection through as part of the job. Licensed and insured, with a Master Plumber on staff and TASK 86/87 certification for gas work.

All major brands, including Lennox, Trane, Carrier, Mitsubishi and Daikin. We recommend equipment based on the house and how you use it rather than pushing one manufacturer.

Yes. This is the kind of job most people are not expecting to pay for all at once, particularly when the old one has just failed. Financing lets the work happen when it needs to rather than when the savings catch up. We finance through Synchrony, subject to credit approval. Ask when you call and we will go through the options for your job.

Yes, free and with no obligation. We look at the house, take the measurements the sizing depends on, and give you a straight number. Use the form and we will be in touch within 24 hours, or call 631-587-0085.
