Eight services.
One number.
From emergency AC repair to full-system installs — heating, cooling and air quality across Nassau and Western Suffolk.
AC Repair & Maintenance
Long Island's humid summers push air conditioners to their limits. Salt-air corrosion from the coast degrades condenser coils and copper refrigerant lines faster than in inland regions. Our NATE-certified technicians diagnose and repair all makes — including Carrier, Lennox, and Trane central air systems — with same-day service and no overtime fees.
AC & Central Air Installation
Replacing or installing a new central air system on Long Island? We perform Manual J load calculations to size your equipment correctly — not guesswork. New AC installations range from $7,500 to $18,000 depending on SEER2 efficiency ratings and home size. We install Carrier, Lennox, Goodman, and Trane systems with full manufacturer warranty registration.
Mini-Split & Ductless AC Systems
Ideal for older Long Island homes without existing ductwork — Cape Cods, colonials, and converted attics. We're authorized installers of Mitsubishi Electric (up to 33.1 SEER2) and Fujitsu (up to 33.0 SEER2) ductless systems. Mini-split installation starts at $3,000 per zone, with multi-zone configurations for whole-home comfort without invasive duct renovation.
Furnace & Heating Repair
When temperatures drop across Nassau and Suffolk counties, a broken furnace is an emergency. We service gas furnaces from Carrier, Lennox, Trane, and Goodman — including diagnostics for ignition failures, blower motor issues, and cracked heat exchangers. Our technicians carry common replacement parts to complete most repairs on the first visit.
Boiler Repair & Service
Long Island has a high concentration of pre-1980 homes with oil and gas boiler heating systems. We service, repair, and replace all boiler types — cast iron, condensing, and steam — from brands like Weil-McLain, Burnham, and Navien. Whether it's a leaking pressure valve, circulator pump failure, or a full boiler replacement, we handle it.
Heat Pump Installation
Heat pumps deliver year-round heating and cooling in a single system — and modern cold-climate models operate efficiently down to -13°F, making them a strong fit for Long Island's Climate Zone 4A winters. We install Carrier, Mitsubishi, and Fujitsu heat pumps. Federal IRA tax credits of up to $2,000 make this the most cost-effective time to upgrade.
AC Tune-Up & Maintenance
Annual AC maintenance prevents 90% of breakdowns and keeps your system running at peak efficiency. Our 21-point tune-up includes refrigerant check, coil inspection, electrical testing, and thermostat calibration. Starting at $89 for spring specials — most tune-ups completed in under 90 minutes.
24/7 Emergency HVAC Service
No heat at 2 AM? AC dies during a July heatwave? We respond to emergency calls 24 hours a day, 7 days a week across Nassau County and Western Suffolk County — with a 90-minute average response time and absolutely no overtime fees. Same rate day or night, because your family's comfort and safety shouldn't cost extra.

Brands we trust.
In our own words.
Independent brand reviews based on 35+ years of field experience installing and servicing every major system on Long Island.
Salt air. Cold snaps.
Designed for both.
Generic advice doesn't work here. Coastal climate, aging housing stock, and sky-high energy costs create challenges only local expertise can solve.
Climate Zone 4A
90°F+ summers. Teens in winter.
Long Island's extreme seasonal swings demand systems rated for both high cooling loads and reliable heating. Undersized or aging equipment fails at the extremes.
Salt-Air Corrosion
Most of Nassau County is within 15 mi of the coast.
Coastal salt air accelerates corrosion on condensers, copper lines, and electrical connections. We spec coil coatings and corrosion-resistant units for every shore-area install.
Unique Housing Stock
Post-war Cape Cods. Pre-war colonials. No two are alike.
Many Long Island homes lack ductwork entirely — making ductless mini-splits the best retrofit. We assess each home individually instead of guessing.
40–60% Higher Energy Costs
PSEG rates are well above the national average.
Upgrading from 14 SEER to 20+ SEER2 can cut cooling costs by 30%. We calculate real payback periods so the upgrade makes financial sense.

"They even followed up the next day to make sure everything was working perfectly."
We've used Home+ for both our furnace tune-up and a new ductless mini-split installation. Both times the team was punctual, clean, and thorough. They even followed up the next day to make sure everything was working perfectly.
