Hicksville’s HVAC work is shaped by the homes themselves – mostly 1950s and 1960s split-levels, ranches, and expanded Capes, many still running ductwork sized for a heating-only system. That means the useful answer to “who should I call for HVAC in Hicksville” is a company that does not blink at an AC retrofit, a high-velocity install, or a cramped-attic mini-split solution. Dalton Heating & Air handles all three of the big jobs Hicksville homeowners call about – AC repair, heat pump installation, and furnace repair – with a written price before anything starts and a full-year written guarantee on every repair. Call (516) 559-4840 and a live person answers.
Why Hicksville Homes Are Different
Hicksville was built fast in the postwar years, and the mechanical systems in those homes have been adapting ever since. Many original duct systems were sized for a furnace only – they move enough warm air through freezing Januaries, but they stall against a Long Island August. When a homeowner here asks about central air for the first time, the job is rarely as simple as dropping a condenser outside. The ducts may be too small, the attic too tight, the return path too weak. So the conversation turns to high-velocity systems, mini-splits, or duct corrections – work that is far more common in Hicksville than in Levittown, where the smaller Cape Cods are simpler to heat and cool.
Then there are the boilers. Some Hicksville homes still carry their original cast iron units – sixty years old, heavy, and reliable until they are not. A technician who works this area knows to check the conversion history, because many of those systems were switched from oil to gas decades ago, and not every conversion was done cleanly. The low-slope “Hicksville split” roof is another tell: tight attic clearances mean running new ductwork is a genuine fight, which is why mini-splits have become the go-to fix for so many homeowners here. Summers lean hot and humid, winters run cold, and the ocean moderates things just enough that high-efficiency heat pumps make sense year-round for a growing share of homes.
Styles & brands we work with







Our Main Hicksville Services
Three jobs account for most of what Hicksville homeowners call us about: diagnosing and fixing a failed AC, putting in a heat pump sized correctly for a mid-century split-level, and repairing a furnace that quit on a cold night. Each has its own page with local detail and pricing, linked below.
AC Repair in Hicksville
Hicksville AC failures hit hard in July and August, when humidity sits on top of them. The common calls here involve undersized ductwork choking airflow, older condensing units short-cycling, and condensate lines backing up in humid weeks. Repairs in this market typically land between $150 and $650 depending on what failed. We carry common parts for the brands Hicksville homes run, and every repair gets a written one-year guarantee. AC Repair in Hicksville covers what we check, what it costs, and what same-day service actually looks like here.

Heat Pump Installation in Hicksville
Heat pumps make sense in Hicksville because the ocean knocks the edges off the winter cold without making summers humid-free – and a mid-century ranch with no existing AC gains cooling and heating in one system. The job here often means working around a low-slope roof, a cramped attic, or a boiler that is staying put for backup. We quote a written fixed price, set an install date, and handle the paperwork for any rebate that applies. Heat Pump Installation in Hicksville goes through the brands, the sizing, and the local install realities.

Furnace Repair in Hicksville
When a Hicksville furnace quits in January, the house gets cold fast, and many of these furnaces are older units serving ductwork that was never oversized. The most common failures we see are failed ignitors, cracked heat exchangers, and blower motors that give out without warning. Furnace repairs here typically run $150 to $700 depending on the part. We stock ignitors, pressure switches, and blower motors for the brands most common in this area, and we come back at no charge if a repair does not hold. Furnace Repair in Hicksville lists the symptoms we diagnose most here and the prices for the common repairs.

FAQs About HVAC Company in Hicksville
Most HVAC repair calls in Hicksville get a same-day or next-day appointment, depending on when you call and how many techs we have in the area that day. Heat pump installations are scheduled ahead with a fixed install date, since equipment gets ordered and sized for your home.
Yes, most HVAC installs and some larger repairs in Hicksville require a permit through the Town of Oyster Bay. We pull the permit as part of the job, coordinate the inspection, and do not start anything until the paperwork is in order.
We do, and those jobs are common in Hicksville. Most homes built here in the 1950s and 1960s still have original ductwork sized for heat only, so adding AC often means high-velocity systems, mini-splits, or duct corrections rather than a simple coil and condenser swap.
