Most furnace repairs in Uniondale run between $150 and $700 depending on the part that failed, and our crews typically reach homes here inside a two-hour window. If your heat is down on a January night with the wind coming off Hempstead Bay, that response time matters. We know Uniondale’s housing stock, we know what salt air does to equipment, and we put the price in writing before any work starts. Call (516) 559-4840 and a live person answers, day or night.
Why Dalton Heating & Air Hempstead Is Uniondale’s Preferred Furnace Repair Company
Uniondale homeowners call us because we show up inside the window we give you, write the price down before touching a screwdriver, and hand you a guarantee on the repair itself, not a handshake promise. Every tech who arrives at your door is background-checked and uniformed, and you’ll know their name before they ring the bell. That’s The Garrison Standard, the operating rules our parent company has held since 2003.
Marco Benitez runs our Uniondale service operation. He trains our techs to check what other crews skip: the uninsulated attic ductwork in 1960s split-levels, the corrosion patterns on condenser coils near the coast, the static pressure on systems that were never sized right in the first place. Our Furnace Repair team deals with these specific failures every week. When a furnace in Uniondale short-cycles, we don’t just swap a part and leave. We find why it failed, so it doesn’t fail again in March.
Styles & brands we work with







Emergency Furnace Repair in Uniondale
Emergency Furnace Repair in Uniondale means a furnace that won’t fire on a night when the temperature dips into the teens and the northeast wind is pushing damp air through every gap in a 1960s ranch. Our dispatch line is answered by a real person 24/7, and our Uniondale techs carry ignitors, gas valves, flame sensors, and blower motors on the truck so most emergency calls get fixed in one visit. A typical emergency repair here runs $150 to $700 depending on the part, and you’ll see every dollar in writing before work begins. The repair is guaranteed in writing for a full year; if it fails in that time, we return at no charge.
No-Heat Calls From Frozen Condensate
High-efficiency furnaces in Uniondale crawlspaces develop ice blockages in their condensate drains during freeze-thaw cycles. The furnace shuts itself down as a safety measure, and the house drops to 50 degrees before you notice. Our techs thaw the line, re-route it to prevent re-freezing, and verify the drain flows before restarting the burner.
Short-Cycling Burners on Cold Mornings
When a furnace fires up, runs for three minutes, then shuts off and repeats, it’s usually a dirty flame sensor or an overheating heat exchanger. This gets worse fast in Uniondale homes where uninsulated attic ductwork forces the furnace to run continuously. The constant cycling stresses the blower motor and the high-limit switch. We test the full sequence and replace the failed component, not just the symptom part.
Furnace Maintenance in Uniondale
Furnace Maintenance in Uniondale means an $80 to $200 service call that catches the corrosion, airflow, and drainage problems that kill furnaces early in this climate. Coastal air here cuts years off uncovered coils. Ductwork in uninsulated attics loses enough heat to cook a blower motor. A twice-yearly inspection, fall and spring, is the cheapest insurance a Uniondale homeowner can buy for a system that runs hard through damp winters and humid summers. We inspect the heat exchanger for cracks, test the ignitor, clean the flame sensor, and check condensate drainage. Every maintenance visit ends with a written report of what we found and what remains.
Fall Pre-Heat Inspection
Before the first cold snap, we check the heat exchanger for hairline cracks, the burner for even flame, and the ignitor for carbon buildup. In Uniondale, we also check the outdoor coil on any heat pump system for salt corrosion before heating season starts. Catching a corroded coil in October beats waking up to a dead system in February.
Spring Condensate and Duct Check
After winter, the freeze-thaw cycle has stressed every outdoor condensate connection. We inspect drains for hairline splits, check the blower wheel for dirt buildup from months of running against damp air from the ocean, and flag any ductwork that’s sagging or leaking. A small duct seal now saves hundreds in wasted fuel next winter.
Trusted Brands We Service in Uniondale
Our techs are factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. We service every one of them here in Uniondale, and we stock the repair parts that fail most often in this specific climate: coated condenser coils, flame sensors, ignitors, gas valves, blower motors, and pressure switches. If your Uniondale furnace needs a Carrier ignitor or a Bryant blower motor, chances are the part is on the truck when we arrive, not ordered and backordered. Dalton Heating & Air Hempstead carries what Uniondale homes actually need, not what the nearest warehouse decides to ship next week.

AfterCommon Furnace Repair Problems We See in Uniondale Homes
- Corroded condenser coils from salt-laden air. Homes within a few miles of the Atlantic see condenser coils fail years faster than inland Nassau County towns. A corroded coil loses refrigerant, the heat pump can’t pull heat, and the furnace runs longer to compensate, overheating the heat exchanger.
- Premature blower motor failure from uninsulated attic ductwork. Many original 1960s homes in Uniondale route ducts through uninsulated attics. In winter, hot supply air loses 15 to 20 degrees before it reaches the rooms, so the furnace runs nearly continuously. The blower motor was never designed for that duty cycle, and it burns out.
- Frozen condensate drains in crawlspaces. High-efficiency furnaces installed in Uniondale’s slab-foundation and crawlspace homes push condensate outside through narrow PVC lines. Spring freeze-thaw cycles plug those lines with ice, tripping the safety switch and shutting the furnace down.
- Tripped high-pressure switches from restricted airflow. Dirty coils, collapsed ducts, and clogged filters all increase static pressure inside the system. The furnace’s pressure switch trips as a safety measure, and the burner won’t stay lit. It looks like an electrical problem, but it’s usually airflow.
Pricing for Furnace Repair in Uniondale, NY
Most furnace repair jobs in Uniondale run $150 to $700. That covers common failures like ignitors, flame sensors, gas valves, blower motors, and pressure switches. A full maintenance tune-up runs $80 to $200. Here’s the line-item breakdown:
| Service | Price Range |
|---|---|
| Furnace Repair | $150 – $700 |
| Tune-Up | $80 – $200 |
What moves a repair from $150 to $700 is the part itself and whether we’re addressing one failure or a chain of them. A corroded condenser coil on a heat pump in Uniondale costs more than a flame sensor because the part is bigger, the labor is longer, and we recommend a coastal-rated, coated replacement that will hold up against salt air. You’ll get the exact number before we start, on paper, and that number won’t change at the door. Estimates are free. Call (516) 559-4840 for a specific quote on your system.

FAQs About Furnace Repair in Uniondale
Salt-laden air from the Atlantic deposits a fine corrosive film on bare aluminum condenser coils, and over three to five years that film breaks down the metal fins and tube walls. In Uniondale this happens substantially faster than inland towns like Garden City, which sit farther from the marine influence. A corroded coil leaks refrigerant, and the system loses heating capacity. The fix is a coated, coastal-rated coil, which costs more upfront but lasts roughly twice as long in this environment. Call (516) 559-4840 to have your coil inspected before you lose heat.
Yes, and it does so in a specific way. Ductwork running through an uninsulated attic loses so much heat in winter that the furnace runs near-continuously trying to reach the thermostat setting. That duty cycle wears out the blower motor years ahead of schedule, and it can also overheat the heat exchanger. Our crew was called to a split-level on Nassau Road in Uniondale where a Carrier furnace was short-cycling and blowing lukewarm air. We found the condenser coil heavily corroded from years of salt air, causing a refrigerant charge loss and tripping the high-pressure switch. We replaced the coil with a coastal-rated, coated version and verified the static pressure to restore proper heat output. Call (516) 559-4840 for an inspection.
No-heat calls from frozen condensate drains are the most common winter emergency in Uniondale’s crawlspace and slab-foundation homes. Freeze-thaw cycles plug the drain line, the furnace’s safety switch trips, and the unit shuts down completely. The second most common is a failed ignitor, which is easy to fix with a stocked replacement part. Both run $150 to $450 in Uniondale. We carry ignitors and condensate repair parts on the truck, so most emergency calls are done in one visit. Call (516) 559-4840 any time.
If your current coil is bare aluminum and your system is more than five years old in Uniondale, talk to us about a coated replacement before it fails. The coastal air here corrodes coils to the point of refrigerant loss, and a planned replacement during a maintenance visit is always cheaper than an emergency repair in February. Coated coils cost more up front, but they hold up roughly twice as long in salt-laden air. We’ll give you a written price and let you decide on your schedule, not the weather’s. Call (516) 559-4840 for a quote.
Twice a year, fall and spring. The salt-laden coastal air in Uniondale corrodes coils and components faster than inland Nassau County, and the freeze-thaw cycles stress condensate lines and outdoor connections every spring. A fall inspection catches coil corrosion before heating season, and a spring visit addresses drainage and airflow issues caused by winter. Each maintenance call runs $80 to $200 and ends with a written report. Call (516) 559-4840 to schedule the next available slot.
