Styles & brands we work with







Mini Split Installation in Uniondale
Mini Split Installation in Uniondale is the retrofit we recommend more than any other for homes built between 1950 and 1975, because the original ductwork in many of these houses simply was never sized for cooling. A 1968 split-level off Jerusalem Avenue taught us that lesson again recently. Our techs found the original ductwork in an uninsulated attic, which had caused the old AC’s evaporator coil to freeze every July. We installed a Daikin heat pump with a corrected refrigerant charge and upsized the return drop, and the homeowner finally held 72°F on the hottest day without tripping the blower motor.
A ductless mini split skips the ducts entirely. An outdoor condenser connects to slim indoor heads mounted on walls or ceilings, each with its own thermostat zone. For a Uniondale ranch or split-level where adding or replacing ductwork would mean tearing out ceilings, a mini split usually lands between $3,500 and $7,500 depending on how many indoor heads the home needs.
When a Mini Split Beats a Ducted System
If your home sits on a slab and the ducts are buried or nonexistent, a ducted heat pump is a nonstarter. Mini splits avoid the problem. They also let you cool only the rooms you use, which matters in split-levels where the lower level stays cold and the bedrooms bake.
Multi-Zone Options for Larger Homes
Garden apartments and expanded ranches often do well with a multi-zone mini split. One outdoor unit can feed up to four or five indoor heads, each set to its own temperature. The written quote itemizes every head and the outdoor unit, so there’s no surprise on install day.
Heat Pump Maintenance in Uniondale
Heat Pump Maintenance in Uniondale should happen at least once a year, and in this climate we recommend spring and fall checks. The salt air here is hard on outdoor condenser coils. Within six to eight years, pinhole corrosion can eat through the coil, the unit loses capacity, and humidity control drops off even though the system still runs. A tune-up runs $80 to $200 and catches that corrosion before it becomes a $4,000 replacement.
During a maintenance visit, our techs check the refrigerant charge, test the capacitor and contactor, clean the coil, inspect the condensate line for freeze-thaw damage, and measure static pressure against manufacturer spec. You get a written report of what was found and what it costs to fix, with no pressure to buy anything.
Spring Start-Up Check
Before the first heat wave, we verify that the reversing valve still shifts between heating and cooling and that the defrost cycle works. A heat pump that can’t defrost will ice over in winter, and by spring it’s often too late to save the compressor.
Post-Storm Inspection
After a nor’easter or a summer thunderstorm, we check for flooded components, debris in the coil, and surge damage to the control board. Don’t restart a flooded condenser on your own. We’ll get to that in the FAQ.
Trusted Brands We Service in Uniondale
Our crews are factory-trained on nine major residential HVAC brands, and in Uniondale we stock local parts for Daikin, Bryant, American Standard, and Carrier. That means faster turnarounds when a replacement coil or control board is needed, and it means we can match parts to the system you already have rather than selling you whatever’s on the truck. If you have an existing heat pump from any of these brands, we’ll service it and extend its life; if it’s time to replace, we’ll give you honest guidance on which brand fits your home and budget.

AfterCommon Heat Pump Installation Problems We See in Uniondale Homes
- Undersized ductwork that can’t support the heat pump’s airflow. Many 1950s – 1970s slab-on-grade homes in Uniondale were built with ducts sized for a furnace, not for cooling. A Manual J load calculation and static pressure test usually confirms the original ducts can’t handle a modern heat pump, which is why mini splits are often the better retrofit.
- Flooded condensers after coastal storms. Heavy rain and nor’easters can leave an outdoor unit sitting in a foot of water. If the compressor windings short when it’s switched back on, the whole unit needs replacement.
- Salt-air corrosion on condenser coils. The Atlantic influence means pinhole leaks in the outdoor coil within six to eight years. A heat pump sized correctly for the home still loses capacity and humidity control if that coil isn’t inspected and coated.
- Surge damage from summer thunderstorms. A lightning strike or power surge takes out the capacitor or control board, and homeowners without a whole-home surge protector face repeat $400 – $650 board replacements.

FAQs About Heat Pump Installation in Uniondale
No. Do not turn it back on. A flooded condenser with wet compressor windings will short the moment power hits it, and that’s a full replacement, not a repair. Call us at (516) 559-4840 before you touch the breaker. We’ll inspect the unit, dry the electrical components properly, and test the windings before any power is restored.
Because the ductwork in many of those homes was designed for a furnace, not for cooling. The original ducts are often undersized, routed through uninsulated attics, and leaky. A Manual J load calculation and static pressure test will tell us if your ducts can support the new heat pump’s airflow. Most of the time they can’t, and a ductless mini split solves the problem without tearing apart ceilings. Call (516) 559-4840 and we’ll run the numbers on your home for free.
Install a whole-home surge protector on your electrical panel. Uniondale gets hard summer thunderstorms, and a close lightning strike will take out the capacitor or control board fast. Without a surge protector, homeowners face repeat $400 – $650 board replacements. We’ll inspect your panel and recommend the right surge protection during any service call.
Not necessarily. Pinhole corrosion from Long Island salt air is common within six to eight years, but it doesn’t always kill the unit. If the coil can be cleaned and coated, and the system still holds refrigerant, you may get several more seasons. If the leaks are widespread, replacement is the smarter money. We’ll show you the coil condition and give you a written quote either way.
Yes. Heat pumps have a high start-up surge, so your generator needs to be sized for the locked rotor amps of the compressor, not just the running watts. An undersized generator will trip or damage the unit. If you’re planning to run your heat pump during an outage, tell us during the estimate and we’ll check the compatibility before installation.
