Furnace repair in Franklin Square typically runs $150 – $700, with most fixes completed same-day when we have the part on the truck. If your heat is out on a cold January night near Rath Park or over by Polk Street School, you don’t want a callback queue. You want a live person, a written price, and a technician whose name you know before they ring the bell. That’s how we work. Call (845) 328-4955 and a real person answers, day or night. We dispatch crews into Franklin Square regularly, and we know the housing stock here: 1950s and 60s split-levels and capes, tight lots, rooftop furnaces, and original equipment that’s older than most of the technicians sent to fix it.
Why Brandt HVAC Co Queens Is Franklin Square’s Preferred Furnace Repair Company
Franklin Square homeowners call us for a reason that has little to do with coupons. They want certainty about who is walking through the door. Before every visit, we send the technician’s name and photo. When they arrive, they show a photo ID badge at the door. This is the Threshold Verified standard, and it matters here more than most places. Franklin Square is a community of families, older homeowners, and people home alone during the day. Opening the door to a stranger shouldn’t feel like a gamble.
Devin Marlowe leads our team, and he’s built the operation around a simple rule: a written price before any work starts, on every job. No exceptions. If a repair fails within 365 days, we return at no charge under our 365-Day Done Right Promise. That’s the guarantee, in writing, on every furnace repair we do in Franklin Square. We service Trane, Lennox, Goodman, and Rheem, among other major brands, and we stock common parts locally so a bad ignitor or gas valve doesn’t leave you waiting on a shipment.
Our Furnace Repair team knows this area’s quirks: rooftop units with water intrusion, 1960s heat exchangers on their last legs, and condensers wedged into walkways where runoff pools. That local knowledge means we diagnose faster and fix it right the first time.
Styles & brands we work with






Furnace Tune Up in Franklin Square
A Furnace Tune Up in Franklin Square runs $80 – $200 and is the single smartest way to avoid a no-heat call in February. It takes about an hour and covers what actually matters on the equipment in this part of Nassau County: burner assembly inspection, flame sensor cleaning, static pressure check, and combustion analysis where the unit allows it.
What a Tune-Up Catches on 1950s and 60s Equipment
Most Franklin Square homes were built between 1945 and 1970. That means original or early-retrofit furnaces with decades of wear. A tune-up on these systems isn’t routine maintenance, it’s a diagnostic pass. We look for hairline cracks in the heat exchanger, a corroded capacitor that’s about to fail, and rollout switches that trip because airflow has degraded over time.
Salt Air and Corrosion
Franklin Square sits close enough to the South Shore that salt air accelerates condenser and burner corrosion, especially on units mounted near foundations where runoff pools. During a tune-up, we check for rust on electrical connections and test the capacitor’s actual microfarad reading against its rating. Catching a weak capacitor in October costs $80 – $200. Ignoring it until December means a no-heat night and an emergency repair.
Emergency Furnace Repair in Franklin Square
Emergency Furnace Repair in Franklin Square is why our phones are answered by a live person 24 hours a day, 7 days a week. When a nor’easter pushes damp cold across the South Shore and your furnace quits at 11 p.m., you call (845) 328-4955. A person picks up. Not a voicemail tree. We dispatch a technician to Franklin Square with the parts likely needed for your system, and you get a written price before anything is touched.
Overnight and Weekend Calls
We run emergency calls into Franklin Square on nights, weekends, and holidays. The repair itself usually falls in the standard $150 – $700 range depending on the failure. An ignitor replacement on a rooftop Lennox might run $180 – $300. A seized blower motor with a corroded capacitor could push toward $450 – $700. You’ll know the exact number in writing before we start.
High-Tension and Dangerous Work
Some furnace failures involve live gas valves, cracked heat exchangers, or electrical components that can shock or start a fire. This is not a YouTube-DIY situation. A cracked heat exchanger can leak carbon monoxide into the house. If your carbon monoxide detector sounds or you smell gas, shut the unit off, ventilate, and call us immediately. Let a trained professional handle the rest.
Trusted Brands We Service in Franklin Square
We repair all major residential furnace brands, and in Franklin Square we see a lot of Trane, Lennox, Goodman, and Rheem equipment, much of it original to the house. On Adams Avenue and similar streets, you can still find 1960s Lennox furnaces running their original heat exchangers. We stock common parts for these systems locally, which means a gas valve or ignitor replacement is often same-day for Franklin Square customers. We also service Carrier, Bryant, York, Daikin, and American Standard. If your furnace has a badge we recognize, we can usually fix it without waiting on a distributor.
Common Furnace Repair Problems We See in Franklin Square Homes
- Corrosion-induced capacitor and contactor failure. Salt air off the South Shore accelerates electrical corrosion, especially on condensers mounted near foundations where runoff pools. These failures kill the blower or outdoor unit suddenly, often on the first cold night when the system runs hardest.
- Heat exchanger cracks in original 1960s Lennox and Carrier furnaces. Damp, cold winters and decades of cycling stress thin metal and open hairline cracks. Many of these units have never had a combustion analysis, so the crack goes unnoticed until carbon monoxide levels trigger an alarm or a failed inspection.
- Rooftop furnace ignitor failures from water intrusion. Franklin Square’s low-slope roofs and tight attic spaces mean furnaces often live in rooftop closets or mechanical niches. Clogged condensate drains or missing flashing let rain reach the burner assembly, shorting the ignitor.
- Seized blower motors from restricted return air. Finished basements and slab-on-grade additions in Franklin Square often choke return-air pathways. The blower works against high static pressure, overheats, and seizes. Then the rollout switch trips and the furnace shuts down.

FAQs About Furnace Repair in Franklin Square
The 1960s Lennox furnaces in Franklin Square were built with cast-iron heat exchangers that outlast anything made today. The first part to fail is almost always the capacitor, which degrades from salt air corrosion and heat cycling, followed by the blower motor. If your original Lennox is still running, a tune-up that tests the capacitor and checks the heat exchanger is the best money you’ll spend. Call (845) 328-4955 for an exact quote.
Check the condensate drain line for clogs and look for water stains around the burner assembly, both signs of water intrusion that shorts ignitors. Also check that the roof flashing around any vents or penetrations hasn’t pulled away. Franklin Square’s low-slope roofs move water slowly, and a small leak becomes a furnace failure fast. If the ignitor is wet or the unit won’t fire, call us rather than trying to dry it out. Water and live electrical components don’t mix.
Yes. Nassau County requires a permit for heat exchanger replacement, and the work must meet current mechanical code. We handle the permit paperwork as part of the job. Given Franklin Square’s rooftop and tight-clearance installations, we also verify the replacement meets manufacturer clearance specs and Nassau County setback rules before installation.
Franklin Square sits closer to the South Shore than Garden City, and salt air carries inland on prevailing winds, accelerating corrosion on burners, electrical connections, and condenser coils. Garden City’s inland position means less salt exposure. If your unit is mounted near a foundation where runoff pools, that compounds it. A tune-up with electrical testing catches the corrosion before it kills the furnace.
Yes. These retrofits are common in Franklin Square, where original hydronic systems were supplemented or replaced with forced-air units in additions built on slab. The challenges are restricted duct runs, limited return air, and tight clearances. We diagnose the system as it was actually installed, not as a textbook drawing. If the repair requires reworking duct pressure or relocating a component to meet code, you’ll get a written price before anything is done.
