Reliable Heating & Air Conditioning for Jericho Homes
Jericho sits on the high middle ground of northern Nassau, where the Expressway, the Northern State and two state routes meet. Summers are humid and warm, with a lot of paved retail frontage along Jericho Turnpike and Route 107 holding heat into the night. Winters bring steady north and west winds across open lots. Two-story colonials with second-floor bedrooms in hot attics push central air systems hardest in July.

Ductless Mini-Split Installation in Jericho
In Jericho, ductless mini-splits often fix the hot second floor or the addition that never got proper ductwork, and they cool finished basements and home offices without rebalancing the whole system.
Ductless mini-split installation: zones, costs and how it works →Housing Stock & HVAC Constraints in Jericho
Most of Jericho was built after World War II, starting with ranches, capes and split-levels on quarter-acre lots and continuing with larger colonials and expanded homes through later decades. Gas is widely available, and a typical Jericho house has a gas furnace with central air, sometimes split into two zones with a second air handler in the attic. Older ranches and splits may still have a boiler and baseboard. Many homes have been expanded or rebuilt, and equipment that was sized for the original house often struggles with the larger one.
Common HVAC Problems in Jericho Homes
Common Jericho calls include second-floor zones that cannot keep up in summer, attic air handlers with clogged condensate drains, gas furnaces with failed ignitors or flame sensors, and older condensers losing capacitors and fan motors. In expanded homes, uneven temperatures between the original rooms and the additions are a regular complaint, usually traced to ducts or zones that were never resized.
Utility Coverage & PSEG Clean Heat Rebates in Jericho
Jericho homes use PSEG Long Island for electricity and National Grid for natural gas, which reaches most streets. For heat pump rebates, PSEG Long Island runs the program; the claim goes through a participating contractor or directly with PSEG, and psegliny.com has the latest terms.

Local Presence in Jericho, NY
We come west on the Expressway or the Northern State and work the neighborhoods on both sides of Jericho Turnpike, the streets off North Broadway and Route 107, and the homes near the Jericho Public Library and the old Quaker meeting house. Because a few Jericho mailing addresses fall inside incorporated villages, we check which permit office applies before quoting a replacement. Two-system houses are common, with a furnace and air handler in the basement for the first floor and a second air handler in the attic for the bedrooms, each with its own thermostat.

Mechanical permits are governed by the Town of Oyster Bay Department of Planning and Development (74 Audrey Avenue, Oyster Bay, NY 11771); village addresses such as Muttontown file with their village.
Most of Jericho is an unincorporated hamlet in the Town of Oyster Bay, so equipment permits go through the Town of Oyster Bay Department of Planning and Development at 74 Audrey Avenue.

Frequently Asked Questions in Jericho, NY
Which town handles HVAC permits in Jericho?
Most of Jericho is in the Town of Oyster Bay, so the Department of Planning and Development at 74 Audrey Avenue handles permits. A few Jericho addresses are in villages such as Muttontown, which have their own offices. K2 does not file permits.
Why is the upstairs of my Jericho colonial so hot?
Second-floor bedrooms sit under a hot attic, and many systems were not sized or balanced for them. A second zone, duct changes or a ductless unit upstairs usually solves it.
My Jericho house was expanded. Why are some rooms colder?
Additions are often tied into ducts or zones sized for the original house. We check airflow and sizing and suggest duct changes or a separate zone.
