How often should I service my HVAC system?

We recommend servicing your HVAC system twice a year - once in spring for your AC and once in fall for your heating system. Regular maintenance extends equipment life, improves efficiency, and prevents costly breakdowns.

What's included in an HVAC tune-up?

Our comprehensive tune-up includes cleaning coils, checking refrigerant levels, inspecting electrical components, testing thermostat calibration, lubricating moving parts, changing filters, and a full system performance analysis.

How long does a typical HVAC system last?

With proper maintenance, air conditioners typically last 15-20 years, and furnaces can last 15-25 years. Regular servicing is key to maximizing your system's lifespan and efficiency.

Do you offer emergency HVAC services?

Yes! We provide 24/7 emergency HVAC service with a 90-minute response time. No overtime fees apply - we charge the same rate day or night because your comfort can't wait.

What areas do you service?

We serve all of Nassau County, NY including Long Island communities. Same-day service is available for most areas. Contact us to confirm service availability in your specific location.

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.

Cooling · Install

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.

Ductless · Install

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.

Heating · Repair

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.

Heating · Boilers

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.

Year-round · Install

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.

Cooling · Maintain

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. Most tune-ups are completed in under 90 minutes.
