Furnace repair in Hempstead, NY typically costs $150 – $700 depending on the part that failed and how long it takes to access. Most calls we run in Hempstead are diagnosed in under an hour and repaired same day, because we carry common OEM parts on the truck. Dalton Heating & Air Hempstead has been doing our Furnace Repair in Hempstead since 2003, led by owner Marco Benitez, who holds the crew to The Garrison Standard: arrive inside the window, put the price in writing before touching the unit, and guarantee the repair in writing for a full year. When heat goes out in Hempstead in January, that’s a problem that can’t wait for a callback. Call (516) 559-4840 and a live person answers, 24/7, not a voice mailbox.
Furnace Maintenance
Furnace Maintenance is the scheduled service that catches small failures before they become a no-heat night. We recommend it once a year in Hempstead, ideally in late September or early October, before the first cold snap hits Nassau County. A Dalton maintenance visit runs $80 – $200 and includes cleaning the burners, testing the ignition, checking carbon monoxide output, and measuring the temperature rise across the heat exchanger. The written report tells you exactly what was found and what, if anything, can wait.
What Gets Cleaned and Tested
We clean the flame sensor, burner assembly, and condensate trap on 90%+ efficiency furnaces. A dirty flame sensor is the most common cause of a furnace that fires and shuts off after five seconds. Fixing that during maintenance costs a fraction of an emergency call later.
What the Report Tells You
Every tune-up ends with a written list of measurements and photos of anything we flagged. You’ll know the carbon monoxide reading, the amp draw on the blower motor, and whether the filter needs changing. No tech at Dalton is paid commission on what they sell, so the report is facts, not a sales script.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair covers the outdoor condenser unit that runs year-round to both heat and cool your home. In Hempstead, where winters hover near freezing, a heat pump losing refrigerant or a failing reversing valve shows up fast: the house won’t hold temperature, or the outdoor unit runs constantly and ices over. Repair costs run $150 – $700, right in line with furnace work, and our techs are factory-trained on Rheem, York, Daikin, and Bryant heat pumps. We stock reversing valves, defrost boards, and capacitors for these makes on the truck.
Reversing Valve and Defrost Board Failures
The reversing valve is what switches a heat pump between heating mode and cooling mode. When it sticks, the system may blow cold air in heating mode. A failed defrost control board means the outdoor coil ices up and the system never clears it, losing efficiency by the hour.
Why Ice on the Coil Matters
Some frost on the outdoor coil is normal in a Nassau County winter. A full block of ice, though, means the defrost cycle isn’t running. The heat pump then runs in a loop it can’t recover from, and the electric strip backup in the air handler kicks in, which shows up instantly on your electric bill. We diagnose this with a thermometer on the liquid line, not guesswork.
Heating Repair
Heating Repair is the catch-all for any system keeping your home warm that isn’t a standard forced-air furnace or boiler, from baseboard hydronic loops to gas-fired unit heaters in basements and garages. The first thing Dalton Heating & Air Hempstead does is confirm the fuel source, the control voltage, and what the thermostat is actually calling for, before opening a panel. Uniondale Furnace Repair and heating repair in Hempstead both run $150 – $700 for most component failures. We carry replacement thermostats, transformers, zone valves, and circulator pumps; if the problem needs a bigger part, we quote it in writing before ordering anything.
Zone Valves and Circulators
Homes with multiple thermostats use zone valves or circulator pumps to route hot water to the right rooms. When one fails, one floor might be warm while another stays cold even though the boiler runs. We test each zone’s end switch and motor separately, so you’re not paying for a new valve when a $4 thermostat wire is the fault.
Control Voltage Problems
A surprising number of heating calls turn out to be a low-voltage issue: a broken thermostat wire, a tripped safety switch, a transformer putting out 19 volts instead of 24. These are quick fixes when diagnosed correctly and maddening when not. That’s the difference a written diagnostic process makes.
Boiler Repair
Boiler Repair is for the hydronic systems many older Hempstead homes still use: water gets heated in a cast-iron or steel boiler and pumped to radiators or baseboards. Boilers run at higher water temperatures than furnaces, and the failures that take them down are pressure-related: a failed expansion tank, a leaking relief valve, a circulator that’s lost its prime. Dalton Heating & Air Hempstead repairs boilers at the same $150 – $700 range as furnaces. A leaking boiler relief valve in a Hempstead basement is the kind of call owner Marco Benitez treats as urgent: the water damage alone can outrun the repair bill if it’s left overnight.
Expansion Tank and Pressure Issues
When an expansion tank waterlogs, boiler pressure climbs on every heating cycle. The relief valve then drips, the floor gets wet, and eventually a pipe joint lets go. We check tank pre-charge with a tire gauge and replace failed tanks the same visit. It’s simple work, but it has to be done before the boiler eats itself.
Circulator and Zone Pump Failure
A circulator with a seized bearing or a failed capacitor is why one zone in the house gets hot while another stays at 60 degrees. Replacing a circulator pump or its motor assembly is a common Hempstead boiler repair that we can usually finish in under two hours with the right pump on the truck.
Gas Furnace Repair
Gas Furnace Repair is the core of what Dalton Heating & Air Hempstead does in Hempstead and our Furnace Repair in East Meadow between October and March. A natural-gas furnace is an appliance that burns fuel, so any repair we do always ends with a combustion test: manifold gas pressure verified, carbon monoxide checked at the vent, and the safety circuit tested. Gas furnace repair runs $150 – $700 in Hempstead, with the higher end covering inducer motors, gas valves, and heat exchangers that are labor-intensive to replace. Get the price in writing before we turn a wrench.
Ignitor and Flame Sensor Replacement
The ignitor is the part that glows to start the burner. When it cracks or weakens, the furnace tries to light and fails, sometimes for days before you notice on a cold morning. Flame sensors get coated with carbon and silica and stop proving the flame, so the gas valve cuts off as a safety measure. Both are quick, low-cost fixes that feel like a total breakdown when they happen.
Gas Valve and Inducer Motor Work
A gas valve that’s failing may not open on demand, or it may open and drop pressure mid-cycle. The inducer motor is what clears the vent and proves draft before the burner fires. Either one failing trips the safety circuit and shuts the system down. We always verify the failure with a manometer or amp clamp before quoting a replacement, because guesswork here is both expensive and unsafe.
Furnace Tune Up
Furnace Tune Up is the same service as Furnace Maintenance, structured as a flat-price visit that gets the system ready for the heating season. Most tune-ups in Hempstead run $80 – $200 and take 60 to 90 minutes. Dalton Heating & Air Hempstead uses a 21-point checklist: gas pressure, burner alignment, blower amp draw, temperature rise, CO levels, flue draft, and safety switches are all measured and written down. You get the report in hand before we leave, and the price is locked before we start.
What’s Included in the Price
The flat rate covers all cleaning, testing, filter check, and a written report. If we find something broken, we give you a separate written quote and you decide. You’re never backed into a repair just because a tech is already in the basement.
When to Schedule It
September and early October are the right months in Hempstead. By mid-November, emergency calls spike as furnaces get their first real run of the year. Scheduling before the rush gets you any date you want, and it means you’re not waiting when a cold front arrives.
Emergency Furnace Repair
Emergency Furnace Repair is what Dalton Heating & Air Hempstead does when a Hempstead home has no heat on a night below freezing. Calls are answered by a live person 24/7, and the on-call tech is a Dalton employee, not a third-party dispatcher. Emergency furnace repair pricing stays in the same $150 – $700 range as standard calls, because we don’t stack overtime charges onto a family already dealing with a cold house. Owner Marco Benitez has been running the emergency rotation since 2003, and the rule doesn’t change: written price before work, same as any call.
What Counts as an Emergency
No heat with temperatures near or below freezing, a gas smell by the furnace, or a carbon monoxide alarm going off are all calls to make immediately. If the alarm is sounding, evacuate first and call 911. We then work with the utility to find the source after the house is safe.
How Fast We Can Get There
In Hempstead, emergency response is usually under two hours depending on call volume and where you are in town. We cover Hempstead and the surrounding communities, and we always call ahead with the tech’s name and what vehicle they’re driving so you know who is walking up your driveway.
Brands We Service
Dalton Heating & Air Hempstead is factory-trained to service Rheem, York, and Daikin furnaces, plus three more of the major makes you’ll find around Nassau County. We service hundreds of Rheem units in Hempstead each year and stock their OEM ignitors, pressure switches, and flame sensors on the truck. York’s modulating furnaces run a different control board layout than most, and our techs have done the factory training to test those boards correctly rather than swapping parts on a hunch.
Daikin furnaces show up often in newer Hempstead installs, and we carry their most common inducer motors and gas valves. Bryant units are also common here, especially in homes built in the last decade. Whether you have Rheem, York, Daikin, Bryant, or any other make, we can diagnose it, quote it in writing, and repair it with the same full-year guarantee.

AfterSigns You Need a Pro Right Now
- The furnace runs but the air is cool. The burners may be cutting out on safety after ignition, or the gas pressure may be low. Guessing here burns fuel and money. A pro checks gas pressure and flame signal before touching anything else.
- The system short-cycles on and off. Usually a heat exchanger limit tripping or a clogged filter driving temperature too high. Each cycle is wear. Left alone, it walks the system toward a cracked heat exchanger.
- You smell gas or get a CO alarm. That is not a troubleshooting moment. Leave the house, call 911 if the CO alarm is sounding, then call us after the house is cleared. We’ll work with the utility on the source.
- The blower runs constantly, even with heat off. Often a stuck relay, a failed thermostat, or a limit switch that won’t reset. The blower motor burns 400 watts an hour; that adds up on a Con Ed bill in Hempstead.
- The pilot light won’t stay lit on older furnaces. A thermocouple gone weak or a pilot tube clogged. It’s an easy fix when diagnosed right, but too many homeowners try to clean it with a wire and end up with an unsafe flame. Let us test it properly.
Our Process, Step by Step
- 1
You call, a human answers. (516) 559-4840 is staffed 24/7 by a Dalton dispatcher in the service area. You get a two-hour arrival window and the name of the tech who’s coming. No automated callback queue, no “sometime between 8 and 6.”
- 2
The tech arrives and listens first. Before opening the furnace, we ask what changed, when you noticed it, and whether anyone in the house has allergies or respiratory trouble. That informs how we test combustion and whether we prioritize airflow or gas pressure.
- 3
Diagnosis on the spot, with tools. We carry a combustion analyzer, manometer, digital multimeter, and an inspection camera for heat exchanger checks. The diagnostic is measured, not guessed.
- 4
Written price, no work without a signature. You get the repair cost in writing. The price covers parts, labor, and the full-year guarantee, and it doesn’t change at the door or after the repair. You sign it, then we work.
- 5
Repair, cleanup, and a walkthrough. We finish the job, run the furnace through two full cycles, verify the carbon monoxide reading is safe, and clean up the work area. Then we show you what we fixed, why it failed, and how the written guarantee works. The van doesn’t leave until you’re satisfied.
How Much Does Furnace Repair Cost in Hempstead?
A furnace repair in Hempstead runs $150 – $700 for the large majority of calls. A flame sensor cleaning or replacement sits at the low end, around $150 – $250. An ignitor swap in a Rheem or York furnace typically lands between $200 and $400. Inducer motors and gas valves run $350 – $650, and a heat exchanger replacement, when it can be done at all, hits the top of that range. The diagnostic is always done first, so the price you get is the price for your actual failure, not a menu guess.
What drives the cost is the part itself, how long it takes to access, and whether the furnace is an 80% or 90%+ efficiency model with extra components like a condensate trap and secondary heat exchanger. What should not drive the cost is the time of day or the temperature outside: Dalton Heating & Air Hempstead does not charge overtime for evening or weekend emergency calls in Hempstead. The free estimate includes the on-site diagnosis. You can say no to any repair without paying a call-out fee for the visit when we do the work.
How to avoid overpaying: never let a tech replace a furnace without showing you the heat exchanger reading or the failed component test. Get the price in writing before any work starts, and ask if the repair is guaranteed for a year. At Dalton, both of those are standard, not an upcharge.
