Great Neck HVAC work comes down to old houses, strict village rules, and coastal air that eats condenser coils. Brandt HVAC handles all of it with a written price before any work starts, and a technician you know by name and photo before the door opens. If your AC quits in July or your boiler acts up in February, call (845) 328-4955 and a live person answers, day or night. This page explains what makes Great Neck jobs different, what repairs and maintenance actually cost here, and where we work.
Why Great Neck Homes Are Different
Great Neck’s housing stock is mostly pre-1980 single-family homes, and a lot of them were built between the 1920s and 1980s. That means we see Tudors with steam heat, mid-century colonials with retrofitted central air, and tight mechanical closets that were never designed for modern equipment. Many homes have finished basements, which pushes HVAC equipment into corners where airflow and access get complicated. A standard condenser won’t always fit where the old one sat, and a furnace swap can turn into custom ductwork faster than in newer construction.
The coastal climate adds another layer. Humid summers and salt air from the Long Island Sound accelerate coil corrosion on outdoor condensers, so units that might last 15 years inland often need attention sooner here. Winters bring freeze-thaw cycles that stress older boiler systems, and many Great Neck homeowners run humidifiers to keep wood floors and trim from drying out. Technicians who work Great Neck regularly also know that some jobs, particularly in Kings Point, involve coordinating with property managers and working around strict noise rules for early morning or late evening service. It’s a different kind of HVAC market, and the work has to account for it.
Styles & brands we work with






Our Main Great Neck Services
The two calls we get most from Great Neck homeowners are for air conditioning failures in summer and furnace or boiler trouble in winter, with seasonal maintenance keeping both systems alive in between.
AC Repair in Great Neck
When a central air system fails in Great Neck during a humid July stretch, the usual culprits are salt-corroded condenser coils, capacitor failures, or low refrigerant from slow leaks in aging line sets. Older retrofitted systems often hide surprises: undersized returns, mismatched air handlers, or duct runs through finished basements that make access tight. We diagnose the specific fault, show you a written price before any work begins, and complete most repairs in a single visit. Every repair includes a written guarantee, and if it fails within the coverage period, we return free under the 365-Day Done Right Promise. Full detail on our AC Repair in Great Neck page.

Furnace Repair in Great Neck
Great Neck’s older heating systems split between steam boilers and forced-air furnaces, and each fails in its own way. Steam systems develop leaks, air vents clog, and pressure controls wear out; forced-air units struggle with failed igniters, blower motors, and cracked heat exchangers. Freeze-thaw cycles put real stress on these systems from December through March, and when heat goes out in a house with a finished basement or young children, waiting isn’t an option. We carry common parts for most major brands and give you a written price before touching anything. Details on our Furnace Repair in Great Neck page.

AC Maintenance in Great Neck
In a coastal climate like Great Neck’s, skipping annual AC maintenance is expensive. Salt air corrodes condenser fins and coil surfaces, and a dirty, corroded unit works harder, runs longer, and fails earlier than it should. Our maintenance visits include a full inspection, coil cleaning where accessible, electrical checks, and a written report of what we found and what it means. We tell you what’s failing before it fails, and what it will cost to fix. Maintenance is $80 – $200 for most Great Neck homes, and our technicians are not paid on what they sell. The full checklist is on our AC Maintenance in Great Neck page.

AfterPricing for HVAC Company in Great Neck, NY
These are the price ranges we typically charge in Great Neck. You’ll always see a written price before any work starts, and that price doesn’t change unless you approve a change in scope.

| Full AC installation or replacement | $3,500 – $7,500 |
| AC or furnace tune-up | $80 – $200 |
Prices in Great Neck run toward the middle and upper end of these ranges for two reasons: access is often tight in older homes with finished basements, and village permit requirements can add paperwork and coordination time.

FAQs About HVAC Company in Great Neck
