Ductless Mini-Split Installation in Lindenhurst, NY

Winter wind off the Great South Bay pulls heat out of older Lindenhurst homes, and a standard heat pump loses output as the temperature falls. Low-temperature models are built to keep heating through the coldest weeks of a Long Island winter. That makes them a real heat source rather than summer cooling with a backup.

In a radiator home, many owners keep the boiler and let the mini split carry spring, fall and summer. In a small cottage with only electric heat or window units, a mini split can become the main system. We ask how you use each room before recommending either approach.

It depends on whether the house has, or can take, ductwork. One of our Lindenhurst jobs was a central heat pump system, which uses ducts like ordinary central air. Rebuilt and raised homes often have attic ducts already, so a ducted heat pump can replace an aging furnace and air conditioner in one project.

Homes without ducts, or with a few rooms the ducts never reached, suit wall-mounted heads better. Some houses end up with both: a ducted system for the main floor and a ductless head for an addition or sunroom.

Up and away from water whenever possible. Many canal streets flooded during Sandy, and an outdoor unit set on the ground can be ruined by a single storm surge. We mount units on wall brackets or raised stands, placed for airflow and service access and away from bedroom windows where fan noise would bother anyone.

Salt air is the long-term concern. We pick the most sheltered wall, keep the unit out of spray from the canal and suggest rinsing the coil with fresh water a few times a year. A line set cover protects the insulation from sun and salt far better than bare foam.

Your address decides it. Homes within the Village of Lindenhurst answer to the Village Building Department, and unincorporated sections answer to the Town of Babylon Building Division at 200 E Sunrise Highway. K2 does not file town or village permits. Please confirm what is required with the correct office before we schedule the work.

We provide manufacturer warranty registration help on new equipment, explained on our warranty page. Rheem KwikComfort financing, with credit provided by Synchrony Bank, subject to credit approval, is described on our financing page.

We protect the floors, mount the head's wall plate, drill one small hole through the wall for the line set, drain and wiring, and set the outdoor unit. Then we pressure-test the lines with nitrogen, pull a deep vacuum, release the refrigerant and test both heating and cooling before we pack up.

Before leaving, we show you how to use the remote, clean the filters and read the basic error lights. Our error code guide is a handy reference later. For yearly care, see maintenance, and for more on our ductless work, the mini split installation page.
