HVAC Company in Hicksville, NY
Most Hicksville homes were built between 1947 and 1965 with oil-fired boilers and cast-iron radiators, not central air or forced-air heat. That single fact shapes nearly every HVAC job we take here, whether it’s threading ductwork through plaster walls or installing a ductless mini-split for first-time cooling. We’re Coldharbour Heating & Air, and our technicians work on the specific problems these postwar Cape Cods and ranches present every day. If you need help now, call us at (817) 402-2972 and a live person will pick up, 24 hours a day.
Why Hicksville Homes Are Different
Hicksville’s housing stock is almost entirely 800-1,400 square foot Cape Cods and one-story ranches, built fast and close together on small lots. Plaster walls, minimal attic clearance, and slab or crawl-space foundations make duct runs difficult and expensive. Many homes still run on original oil burners with gravity or forced hot-water radiator loops, so we’re often doing oil-to-gas conversions and first-time cooling installations at the same time.
The location matters too. Hicksville sits inland in Nassau County, close enough to the Atlantic and Long Island Sound to pull in heavy summer humidity. That latent load means proper equipment sizing isn’t about comfort alone, it’s about whether your system can actually dehumidify while it cools. And PSEG Long Island’s electricity rates are among the highest in the continental US, so SEER ratings and heat-pump efficiency math become a real part of the conversation, not a footnote.
Salt air off the South Shore and Long Island Sound accelerates corrosion on outdoor condenser units. We regularly find 8-10 year old units with fin and coil damage you’d expect at 15 years. Annual coil cleaning and corrosion-resistant coating aren’t upsells here, they’re standard practice if you want equipment to last.
Our Main Hicksville Services
Here are the three services Hicksville homeowners call us about most often. Each one has its own dedicated page with full details on pricing, common problems, and what to expect.
AC Repair in Hicksville
AC repair in Hicksville usually means addressing systems that are working harder than they should, either because they’re undersized for the humidity load or because salt corrosion has damaged the condenser coils. We see a lot of refrigerant leaks and compressor strain on systems that were never properly maintained for coastal conditions. Our technicians carry common parts for Rheem, York, and Bryant systems, and most repairs are completed same day. AC Repair in Hicksville covers typical costs, what fails most often, and how our 365-Day Done Right Promise works on every repair.

Furnace Repair in Hicksville
Furnace repair here often means working on oil-to-gas conversions that aren’t quite right, or fixing ignition and burner problems in aging systems that have been patched too many times. Many Hicksville homes still heat with oil-fired boilers feeding original radiator loops, so we diagnose whether the problem is the burner, the circulator pump, or the control system. We don’t push replacement unless it’s actually the better option. Furnace Repair in Hicksville explains our diagnostic process and pricing.

AC Installation in Hicksville
AC installation in Hicksville is usually a retrofit job. Homes without existing ductwork need either creative duct routing through finished walls and cramped attics, or more commonly, ductless mini-split systems that deliver cooling without tearing the house apart. We size every system to handle both temperature and humidity loads, and we factor in PSEG’s high rates when recommending SEER ratings and heat-pump options. AC Installation in Hicksville covers equipment choices, rebates, and how we handle the permitting.

What Hicksville Customers Say
"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
