Fast, Reliable Furnace Repair Across Hicksville

Call (817) 402-2972

We’re Coldharbour Heating & Air, and we’ve been dispatching crews to Hicksville from our New York City office since 2003. We know the postwar Cape Cods south of the LIRR main line, the ranches along Newbridge Road, and the split-levels near the Broadway Mall. These houses were built fast between 1947 and 1965, and many still run the original oil-fired boiler that the builder installed when Harry Truman was president. That matters because a technician who doesn’t recognize a gravity hot-water loop or a tankless coil can misdiagnose the problem and cost you a second service call.

Our phones are answered by a live person 24 hours a day, 7 days a week. Call (817) 402-2972 and we’ll give you a firm arrival window, a written price before any work starts, and our Furnace Repair guarantee in writing.

Why Coldharbour Heating & Air Is Hicksville’s Preferred Furnace Repair Company

We don’t ask homeowners to take our word for anything. Every repair comes with a written price before the first tool comes out, and a written 365-Day Done Right Promise before the technician leaves. If the repair fails inside that full year, we come back and correct it at no charge. That’s The Kingswell Way, and it’s how every independently owned and operated member of the Kingswell network works, including ours.

Our technicians are background-checked and uniformed, and they’re trained to service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Hicksville homeowners, that means the technician who shows up can work on whatever system is already in your home, whether it’s a 30-year-old oil boiler in a Cape Cod off Division Avenue or a newer gas furnace in a renovated ranch near Jerusalem Avenue.

We answer the phone live around the clock. No voicemail trees, no “press 1 for service,” no waiting until morning when your boiler quits at midnight on a February Sunday. Dispatch is coordinated from our New York City office, but crews serve Hicksville locally and carry the parts that fail most often in this market.

Gas Furnace Repair in Hicksville

Gas Furnace Repair in Hicksville covers everything from igniter failures and dirty flame sensors to cracked heat exchangers and failing gas valves. Most gas furnace repairs we handle in Hicksville fall in the $150-$700 range, with simpler fixes like igniter replacements running toward the lower end and heat exchanger work toward the upper end. We see more gas conversions now than a decade ago, as homeowners along South Oyster Bay Road and in the Levittown-adjacent blocks switch off oil, but gas furnaces still represent a minority of the heating stock in the older Cape Cods.

Igniter and Flame Sensor Service

A hot-surface igniter (the ceramic element that lights the gas) typically fails after 3-5 years of seasonal cycling. In Hicksville, where many furnaces sit in damp basements with stone foundations, we see premature failure from moisture corrosion. The fix is straightforward: diagnosis, replacement, and combustion analysis to confirm safe operation. Most run $150-$280, parts and labor included.

Heat Exchanger Inspection and Replacement

The heat exchanger is the metal chamber that separates combustion gases from the air you breathe. Cracks are a safety issue, not a maintenance item, and we shut the system down until they’re resolved. In Hicksville’s older homes with poor return-air pathways, oversized furnaces cycle on high-limit and stress the exchanger metal. Replacement is a significant repair, often at the upper end of our range, and we always document the crack with a photo for the homeowner.

Furnace Tune Up in Hicksville

Furnace Tune Up in Hicksville means combustion analysis, safety control testing, and a written report of what we actually found, not a sales pitch. Our tune-ups run $80-$200, and the technician is not paid on what he sells you afterward. That’s a core part of The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails.

What the Tune-Up Includes

We test gas pressure or oil nozzle flow, check draft and CO levels, inspect the heat exchanger with a borescope, clean the burner assembly, and test every safety control from the high-limit switch to the rollout. For oil systems, we check the filter, nozzle, and pump strainer. You get a written report with readings, photos if we find something, and a clear recommendation with no pressure.

When to Schedule

We recommend a tune-up in early fall, before the first cold snap has every HVAC company in Nassau County booked solid. For oil-fired systems, which still heat a significant share of Hicksville’s postwar housing, annual service is not optional, it’s how you avoid a mid-winter nozzle clog or filter blockage that leaves you with no heat and a house full of frozen pipes.

Trusted Brands We Service in Hicksville

Our trucks carry parts and diagnostic tools for Trane, Lennox, Goodman, and Rheem, plus five other major residential brands. We don’t have to order a igniter for your Lennox Elite series or a control board for your Rheem Classic and make you wait three days. That matters in Hicksville, where a January cold front can drop temperatures into the single digits and a house with no heat is not a comfort problem, it’s a safety problem. For oil-fired Carrier units, which we see regularly in the Cape Cods south of the LIRR, we stock aquastats, primary controls, and nozzle assemblies. Fast turnaround is part of the job.

Common Furnace Repair Problems We See in Hicksville Homes

• Short-cycling oil-fired boilers in drafty postwar Capes. These houses were never sized for modern wind exposure and have no wind shelter. The boiler heats up fast, satisfies the thermostat, shuts off, then loses heat through single-pane windows and uninsulated walls, forcing a restart minutes later. The fix is rarely the boiler itself, it’s addressing the heat loss or adding a buffer tank.
• Cracked heat exchangers from oversized furnaces cycling on high-limit. Older Hicksville homes with poor attic insulation and no return-air pathways force the furnace to work harder than designed. The heat builds up, the high-limit switch trips, and the metal fatigues over years of thermal stress.
• Capacitor and blower motor failures in corroded condensers. Salt-laden air off the South Shore and Long Island Sound ages outdoor units 8-10 years faster than inland climates. Homeowners often mistake the symptom, poor airflow or no cooling, for a simple thermostat calibration issue when the real problem is a seized blower or swollen capacitor.
• Aquastat failures in oil-fired Carrier units with tankless coils. The aquastat controls water temperature in a boiler that also makes your domestic hot water. When it drifts out of calibration, you get scalding tap water or none at all, and the boiler short-cycles trying to maintain two temperatures at once.
