Call about a system that is not working and you get a straight answer about what it probably needs, what the visit covers, and what it will cost before anything is scheduled. That is how every call goes, whether the question is about a furnace that quit overnight, an AC running but not cooling, or a boiler that has lost pressure in one zone. We handle the full range of residential and commercial heating and cooling work across Port Washington and the surrounding area in Nassau County.
Port Washington is a town built largely on older housing stock, and that shapes the work. Boiler systems, oil heat, and homes without any ductwork at all are common here. So are additions that were never properly connected to the main system, and equipment that has been running for years without a service visit. We work on all of it.
Call (475) 239-2878 to talk through what your system needs. We take calls every day from 6:30 AM to 9:30 PM.
Before any visit is scheduled, the call covers what the system is doing, what type of equipment you have, and roughly how old it is. That is usually enough to scope the job and confirm the rate. If the situation is more involved, we ask a few more questions before settling the price.
What helps on that first call: the equipment type (furnace, boiler, heat pump, central AC, ductless unit), the symptom as specifically as you can describe it, and whether the problem is in one area of the home or the whole system. A boiler that is not heating one zone is a different conversation from a furnace that will not ignite at all. The more specific the description, the faster we can confirm what the visit covers.
We confirm the price before anything is booked. You know what it covers and what it costs before the person who comes out arrives.
Pricing on an HVAC call depends on what the fault turns out to be, what has to be accessed to reach it, and whether a repair or a replacement is the more practical answer. A capacitor swap on a unit that is otherwise in good condition is a straightforward job. A heat exchanger that has cracked on a furnace near the end of its useful life puts the repair cost and the replacement cost close enough together that the honest answer is to explain both and let you decide.
Older equipment is assessed on its own merits. You get told when a repair is not going to hold, and what the alternative looks like, before any commitment is made. That applies to boilers, furnaces, heat pumps, and ductless systems alike.
What can change a quote after the diagnostic: a fault that turns out to be deeper in the system than the symptom suggested, a component that requires a part to be ordered, or a code-related correction that the existing installation needs before the new work can proceed. Any of those gets explained before the bill changes.
Homes in this part of Nassau County range from post-war construction to properties that predate central air entirely. Equipment installed in those homes was sized and connected to what existed at the time, which does not always match what the house needs now. A system that has never been serviced, ductwork that was added in sections over the years, or a boiler that is still on its original controls all present their own version of the same challenge: the diagnostic has to account for the whole system, not just the part that stopped working.
Access matters on older properties. A boiler tucked into a utility room with low clearance, a furnace in a finished basement, or an outdoor unit that has been partially enclosed by later construction all affect how a job is approached. We work through those situations on the call so the visit does not produce surprises.
When there is no heat or no cooling at all, that call goes to the front of the line. We take short-notice and emergency work every day from 6:30 AM to 9:30 PM. The scope and the price are confirmed on the phone before anyone is dispatched, so the visit starts with a clear picture of what is being done and what it costs.
For rental properties and commercial spaces that need to stay occupied or open, we discuss timing on the call. A boiler repair in a multi-unit building and a furnace replacement in an occupied home both require a conversation about access and scheduling before the visit is booked.
Property managers dealing with a tenant's no-heat or no-cool call get the same process as a homeowner: the fault diagnosed, the repair scoped, the price confirmed before work starts. If the property needs to stay accessible during the visit, that gets worked out before anyone comes out. We service heating and cooling in every season, and short-notice calls are part of what we handle.
When the job is done, we leave the space clean and the system tested. The person who comes out walks through what was found, what was done, and what the system is doing now before the visit ends. If a follow-up is needed or a part had to be ordered, that is explained before anyone leaves.
A furnace that will not turn on, one that runs but blows cold air, or one that cannot hold the setpoint on a cold night all point to specific components. The diagnostic covers the ignition system, the heat exchanger, the airflow path, and the controls. Each of those can cause the same symptom through a different failure, which is why the diagnostic comes before any recommendation.
A boiler that has lost pressure, a zone that is not heating, or a circulator pump that has stopped moving water are among the most common calls in this part of the Northeast. The visit covers the full hydronic loop: zone valves, circulator, expansion tank, pressure relief, and heat output at each zone. Steam systems carry their own set of failure points, and we work on those too.
An igniter that is failing intermittently or a flame sensor coated with residue will cause a furnace to attempt a start, fail, and lock out. The result is a system that seems to try and then stops, often with a fault code on the board. Cleaning or replacing the sensor is one of the more common furnace repairs in a region where heating systems run hard through a long season.
These are the components most likely to cause an AC or heat pump to fail at the start of the cooling season after sitting idle through winter. A capacitor that can no longer hold a charge will prevent the compressor or fan motor from starting. A contactor that has pitted or burned will do the same. A control board fault can produce almost any symptom, which is why the diagnostic works through the simpler components first.
An addition that was built without extending the duct system properly will always run warmer or cooler than the rest of the home. The fix depends on what the existing system can support and how the addition is connected. Sometimes the answer is extending the existing ductwork and resizing the runs. In homes without any ductwork at all, a ductless mini-split is often the cleaner solution, and we handle both.
An older thermostat reads the temperature at one point in the home and cycles the system on and off based on that reading alone. A modern programmable or smart control adjusts to schedules, learns patterns, and communicates faults before they become failures. In a home with a boiler and zone valves, a smart thermostat per zone gives a level of control that a single setpoint never could.
Replacing a thermostat on its own is worth it when the existing control is causing the system to cycle incorrectly, when it cannot communicate with newer equipment, or when the property is ready for scheduling and remote access. The wiring involved stays on the low-voltage control side of the HVAC system. We go through the options on the call.

Homes without a central duct system have a few practical options for adding heating and cooling: extending existing ductwork where it exists and the system can support it, installing a ductless mini-split for a specific room or zone, or replacing a whole-home system with a ductless multi-zone setup. The right answer depends on the home's layout, what the existing equipment can support, and what the goal is. We go through the options on the call before anything is scheduled.
Duct leaks are identified through a combination of airflow measurement at the registers, pressure testing, and a visual inspection of accessible sections. The results tell us where the losses are occurring and what it will take to address them.
Coverage is based on the address, not the town boundary.

Boiler systems and oil-fired heating are among the most common setups in older homes throughout Nassau County, and Port Washington has a significant share of both. We service and repair boilers, hydronic systems, and oil-fired equipment, and we handle oil-to-gas and oil-to-heat-pump conversions for homeowners considering a change.
Call (475) 239-2878 to describe what your system is doing and we will go through what the visit covers.
Yes. A clogged filter is one of the most common causes of reduced airflow, poor cooling, and short cycling, and replacing it costs nothing. If the system is still not performing correctly after a filter change, that is useful information for the diagnostic and worth describing when you call.
Whether the equipment is a boiler that has been running since the house was built, a heat pump that stopped working at the start of the season, or a furnace that has developed a fault nobody has had time to chase down, the first step is the same: call (475) 239-2878, describe what the system is doing, and we will go from there. We take calls every day from 6:30 AM to 9:30 PM.

Every heating and cooling call starts the same way: the scope discussed on the phone, the price confirmed before anything is scheduled. We handle the full range of residential and commercial HVAC work across Port Washington and Nassau County, from a seasonal tune-up on a boiler to a full ductless mini-split installation in a home without existing ductwork. The table below lays out what each service covers, who it fits best, and what is worth knowing before you call.
| Service Type | What the Service Includes | Best For | Helpful Details |
|---|---|---|---|
| Heat Pump Repair & Service | Refrigerant charge and reversing valve check, Coil and defrost cycle inspection, Electrical controls on the unit, Heating and cooling mode tested | Properties relying on a heat pump year-round for both heating and cooling | A heat pump that struggles in one mode but not the other often points to the reversing valve, which is checked as part of every diagnostic. |
| Boiler & Hydronic Heating Service | Circulator pump and expansion tank check, Heat exchanger inspection, Pressure and controls diagnostic, Boiler repair and replacement | Port Washington homes with radiator-based hot water or steam heating systems | Boiler systems are common in older Nassau County homes and require a diagnostic approach that differs from forced-air equipment. The full system is assessed, not just the unit. |
| Full System Installation & ReplacementMost Popular | Load calculation and equipment sizing, Full system removal and installation, Residential and commercial scope, Price confirmed before work begins | Homeowners, landlords, and commercial clients replacing aging or failed equipment | Sizing the replacement to the actual load of the space matters as much as the equipment brand. An oversized system short-cycles and an undersized one runs constantly. |
