About HVAC service in Mineola
Mineola is an incorporated village, and its housing predates most of what we service elsewhere on the island — a lot of 1920s through 1940s homes, many still on hydronic or steam heat that was never converted. Work here means a comfort level with cast iron, not just sheet metal. ZIP 11501, 7.1 miles from our Levittown shop.

What we see in Mineola
Common HVAC issues by season
We regularly service Mineola year-round. Here's what tends to fail and when.
Summer in Mineola
- PTACs that blow but do not cool — Through-wall units near the LIRR station clog with lint and lose cooling capacity, and failing fan motors and low refrigerant are common.
- Water-source heat pump trouble — Closet units in condo buildings depend on a building water loop and strainers. Poor flow or a clogged coil leaves apartments warm.
- Ductless drain and sensor faults — Mini-splits in older units and rentals flash error codes or leak when condensate drains clog or sensors drift.
- Sudden warm air — A system that cooled fine yesterday and blows warm today is often a failed capacitor, contactor or fan motor during a heat wave, not a sign that the whole unit is finished.
Winter in Mineola
- Stuck steam vents — One and two-pipe steam in the older village homes needs working main and radiator vents. Stuck vents leave some radiators cold and others scalding.
- Low-water cutoff lockouts — A dirty cutoff trips the boiler off even when water is fine, leaving the house without heat until the control is flushed or replaced.
- Air-bound radiators — Two-pipe radiators that never fill with steam usually have trapped air or failed traps, which a proper vent and trap check can correct.
- PTAC heating faults — Condo through-wall units can lose heat when strips fail or controls misread the room, and the unit then blows only cool air.
Deep dive · Mineola
Your HVAC company in Mineola, NY
Mineola is unusual for Nassau: alongside the older village houses, a large share of the housing stock is mid-rise condos and rentals near the LIRR station. Those buildings run PTAC units, water-source heat pumps, or ductless splits instead of central systems — different parts, different diagnostics, and building access rules we already know.
Condo PTAC and water-source units
We replace and repair through-wall PTACs and closet water-source heat pumps, including sleeve and grille fit-ups so the exterior stays uniform.
Ductless mini-split repair
Blinking-light error codes on Mitsubishi, Daikin, LG, and Fujitsu heads. We read the code and fix the cause instead of resetting the board and leaving.
Village home steam boilers
Cast-iron and steam systems from Weil-McLain, Burnham, and Peerless — repair, near-boiler piping corrections, and full replacement.
Central AC and furnace repair
Same-day diagnosis is usually available, with a $199 fee that is waived when you approve the repair.
Steam, hydronic heat, and ductless cooling in Mineola
Our Mineola AC repair page covers cooling breakdowns. The heating side is where this village genuinely differs from the postwar tract towns around it, and where the wrong contractor does expensive damage.
Steam system service
One and two-pipe steam: main vents, radiator vents, low-water cutoffs, and near-boiler piping corrected rather than ignored.
Boiler replacement
Sized by measured heat loss. On steam we size to connected radiator load, which is not the same calculation.
Old boiler removal
When a boiler is replaced, the old cast-iron unit is removed and hauled away as part of the job rather than left in the basement.
Cooling without ducts
For homes with no duct system at all, high-wall and ducted-cassette mini-splits avoid tearing up prewar plaster.

"Had my furnace maintenance done and I’m very happy with the service. The technician was friendly, professional, and took the time to check everything carefully. He explained what he was doing and made sure the furnace was running properly before he left. I’m in Hicksville and it’s nice to find someone local who is reliable and does good work. I would definitely recommend them for furnace maintenance or HVAC service."

"I had a fantastic experience withLong Island HVAC Repair! My ac system was struggling to cool and I noticed a frozen line near the unit. I called for an emergency repair and they were at my home in 90 mins. The technician was professional, quickly located the leak, and had the system running perfectly in no time. Highly recommend for any local Levittown heating repairs!"

FAQs
Mineola HVAC questions, answered
My condo's PTAC runs but barely cools. What should I check first?+
Start with the filter and the coil, since lint and dust choke airflow fast, and make sure the unit's drain is not blocked. If it still runs weak, the problem may be a failing fan motor, refrigerant loss or a bad control board. In Mineola, check your building's rules for contractor access before work begins.
Can a steam boiler in a Mineola Village house be replaced with a smaller one?+
Possibly. Steam boilers are sized to the connected radiators, not the same heat loss calculation used for hot water or forced air. Too big a boiler short-cycles and wastes fuel. We measure the radiators and piping first, and fix near-boiler piping that was wrong the first time.
My ductless unit in a Mineola rental flashes an error light. What can I try before calling?+
Reset the power at the breaker, clean or replace the filter, and check that the outdoor unit is not blocked. A flashing light can also mean a condensate or sensor fault. If the code returns after a reset, note the pattern of flashes and share it when you call.
Do you provide HVAC service in Mineola, NY?+
Yes — Mineola (ZIP 11501) is well within our 9-mile service radius. We're just 7.1 miles away, so Mineola addresses usually get same-day appointments.

How much does AC or furnace repair cost in Mineola?+
Our diagnostic visit in Mineola is a flat $199, waived when you approve the repair. Most common AC and furnace repairs — capacitors, ignitors, flame sensors, contactors, blower motors — run $180–$650 all-in with upfront flat-rate pricing before any work starts. Bigger jobs like refrigerant leak repair or a blower replacement are quoted on the spot, and if a repair no longer makes sense on an older system we'll show you repair-vs-replace numbers side by side.
Do you offer financing for Mineola homeowners?+
Yes — through Synchrony Home Financing. Mineola homeowners can apply for $0 down on approved credit, with monthly plans and full terms in writing before you sign.
What rebates can I get on a new system in Mineola?+
