We carry a workmanship guarantee on every HVAC job, so you are not left wondering whether the repair will hold.
We work with homeowners dealing with a system that stopped working, property managers keeping rental units comfortable, and commercial clients who need reliable heating and cooling to keep their operations running. AC repair and service, furnace repair and service, heat pump installation and repair, full HVAC system replacement, preventive maintenance, and airflow and uneven-temperature troubleshooting are all part of what we do every day.
Give us a call and we'll get the comfort back.
From aging systems to brand-new installs, we handle every AC situation a Lynbrook home or business runs into. If your air conditioner stopped cooling, is making unusual sounds, or simply is not keeping up on a humid August afternoon, we diagnose the problem and walk you through the fix.
A typical service visit covers a full system diagnosis, refrigerant leak check, condenser and compressor inspection, evaporator coil cleaning and assessment, and an airflow evaluation. We tell you what we found, what it will take to fix it, and what it will cost before any work begins. For systems that have reached the end of their useful life, we handle central air installation and full AC replacement as well. Same-day and emergency no-cool service is available when you cannot wait.
Pricing on AC repair and replacement is discussed upfront. Pick up the phone and we'll handle the system.
Nassau County winters are not mild. When a furnace stops working or starts blowing cold air, getting it fixed quickly is not optional. We handle emergency no-heat calls, furnace repair and replacement, heating system installation, and fall pre-season tune-ups and inspections.
Before a small issue turns into a full breakdown, a furnace inspection can catch worn components, ignition problems, and airflow restrictions that shorten equipment life. We check heat exchangers, burners, filters, and controls and give you a clear picture of where your system stands. If replacement makes more sense than repair, we help you select the right system and install it to manufacturer and code standards.
We're one phone call from getting your comfort right.
Not every HVAC company works the same way when it comes to heat pumps. We service and install them for both residential and commercial customers, covering heat pump repair, heat pump replacement, and new heat pump installation as an energy-efficiency upgrade.
A heat pump handles both heating and cooling from a single system, which makes it a strong fit for properties that want to simplify their equipment and reduce fuel costs. If your heat pump is not heating in winter or not cooling in summer, we diagnose the issue and get it back in service. Emergency heat pump repair is available when the system goes down at the wrong time.

Long Island's climate is demanding in both directions: cold, humid winters that put real strain on heating systems and warm, humid summers that push cooling equipment hard. Add in some of the oldest housing stock in the region, and you get a specific set of HVAC needs that come up again and again in Lynbrook. The three services below reflect what we see most often and what we are built to handle.
A large share of Nassau County homes still run on boiler systems, and many of those systems have been in service for decades. Steam and hot-water radiator setups are reliable when they are maintained, but annual service before the heating season is not optional. We handle boiler repair, boiler service, boiler installation, and full boiler replacement. If your boiler is not working, we offer emergency boiler repair and will diagnose the problem fast. Repair and replacement costs are discussed before any work begins.
The Northeast carries the overwhelming majority of the country's oil-heat homes, and Long Island is no exception. Many Lynbrook homeowners are making the shift away from oil, either to natural gas or to a modern heat pump system. We handle the full process: system assessment, equipment selection, and installation. The result is a more consistent heat source and a long-term change in how the home manages energy. We approach every conversion as a full HVAC system replacement and make sure the new equipment is installed to code.
Many older Lynbrook homes were built without ductwork, and adding it is not always practical or cost-effective. A ductless mini-split system solves that problem cleanly. We install mini-splits for whole-home comfort, room additions, converted spaces, and zoning situations where different areas need different temperature control. Mini-splits handle both heating and cooling, which makes them a year-round solution. We also service and repair existing mini-split systems when they stop working.
We're one phone call from getting your comfort right.
Every home's heating and cooling setup tells a different story, and the equipment is only part of it. Leaking or poorly sealed ductwork can undercut even a well-maintained system, sending conditioned air into walls and attics instead of living spaces. We handle duct repair, duct sealing, and ductwork installation, and we check airflow and pressure as part of any ductwork job.
Thermostat problems are more common than most people expect. If your thermostat is not reading correctly, not communicating with the system, or simply needs an upgrade, we handle thermostat replacement and smart thermostat installation. A properly calibrated control makes a real difference in how consistently a system performs.
For indoor air quality, we install air filtration systems and whole-home air purifiers that reduce allergens, dust, and airborne contaminants. We protect your floors and finishes while we work, so the house is left the way we found it.
Give us a call and we'll get the comfort back.
Before a small issue turns into a full breakdown, a quick call can save the day. But when the system is already down, speed is everything. We offer same-day and after-hours emergency HVAC service for no-heat, no-cool, and full system-down situations. That covers emergency furnace repair, emergency AC repair, emergency boiler repair, and emergency heat pump service for both residential and commercial customers.
When you call, you reach someone who can get a technician to your door. We ask a few questions about the situation, give you a realistic time window, and show up ready to work. We pull the permit. We install it to code. We stand behind it.

We serve the full range of customers across Nassau County, from single-family homeowners to landlords managing multiple rental units to property managers and commercial accounts. On the residential side, that means home HVAC repair, home HVAC installation, seasonal maintenance, and rental property HVAC service that keeps tenants comfortable and units up to code.
On the commercial side, we handle commercial HVAC repair, commercial heating repair, commercial AC repair, commercial HVAC installation, and new construction HVAC work. We understand that a commercial system going down affects more than just comfort, and we respond accordingly. We are a local HVAC company homeowners rely on, and commercial clients come back to us for the same reason: the work is done right and we stand behind it.
Pick up the phone and we'll handle the system.
Every home's heating and cooling setup tells a different story, but the case for regular maintenance is the same everywhere. A spring AC tune-up and a fall furnace tune-up catch problems before they become expensive repairs and keep equipment running efficiently through the season.
A standard tune-up covers filter inspection and replacement, coil cleaning, refrigerant level check, thermostat calibration, airflow assessment, and a general inspection of components for wear or early failure. Annual HVAC inspections and diagnostics also give you a clear picture of where your system stands before a warranty question or an unexpected breakdown comes up. Regular maintenance extends equipment life and protects the investment you have already made in your system.
We're one phone call from getting your comfort right.
Not every HVAC company works the same way when it comes to pricing. We discuss costs before work begins, whether that is a repair, a diagnostic, a service call, or a full system replacement. There are no surprises after the job is done.
HVAC repair costs, replacement costs, and diagnostic fees vary depending on the system, the problem, and the scope of work. The right way to get a number that applies to your situation is to call for a quote. We will ask about your system, talk through what you are experiencing, and give you a clear picture of what to expect. We keep the process simple and the communication honest.
Pick up the phone and we'll get started.
A boiler that is losing pressure frequently, heating unevenly, or requiring repeated repairs is telling you it is near the end of its useful life. We will inspect the system and give you an honest assessment of whether a repair makes financial sense or whether a replacement is the better investment at this point.
We handle the full HVAC equipment side of the transition: system assessment, equipment selection, and installation of the new heating unit along with any ductwork or hydronic connections it requires. For any gas-line or fuel-supply work, we coordinate with the appropriate trades so the full project comes together correctly.
For homes built without central ductwork, a mini-split is often the cleanest and most cost-effective solution. We install single-zone and multi-zone systems that handle both heating and cooling year-round, and we position the equipment to minimize visual impact while maximizing efficiency.
A boiler service visit includes an inspection of the heat exchanger, burner, circulator pump, zone valves, and pressure relief components, along with a check of the controls and a test run of the full system. We also look for signs of uneven heat distribution and address them as part of the visit.
A system that is completely down with no heat in winter, no cooling during a heat wave, or a boiler that has shut off entirely qualifies as an emergency. We offer same-day and after-hours response for those situations and prioritize them at the top of our schedule.
If you have no heat, use space heaters in the rooms you are occupying and keep interior doors closed to hold warmth. If you have no cooling, close blinds on sun-facing windows and avoid running heat-generating appliances. Do not try to force a system to run if it has shut down on its own, as that can cause additional damage.
We inspect the evaporator coil, blower motor, filter, drain pan and condensate line, refrigerant lines, and electrical connections at the unit. We also check airflow through the system and look for signs of ice buildup, which can indicate a refrigerant or airflow problem.
Warm or barely cool air from the vents, frequent short cycling, unusual sounds during operation, ice on the refrigerant lines, or a significant increase in energy use without a change in comfort level are all signs the system needs attention. Catching these early usually means a repair rather than a replacement.
Banging or clanking usually points to something loose or broken inside the unit. Squealing often means a belt or bearing issue. Rattling can be debris in the system or loose panels. None of these sounds are normal, and all of them are worth a diagnostic call before the problem gets worse.
If certain rooms are always too hot or too cold while others are comfortable, leaking or poorly sealed ductwork is often the cause. If the whole home is uncomfortable, the equipment itself is more likely the issue. We diagnose both as part of a service visit and give you a clear answer before recommending any work.

How do I know if my system needs a repair or a full replacement?
Age and repair history are the clearest indicators. A system that is 15 years or older, has needed repeated repairs in recent seasons, or can no longer keep the home at a comfortable temperature is often a better candidate for replacement than another fix. We give you an honest assessment of where the equipment stands and what makes financial sense for your situation before recommending anything.
What are the signs of a refrigerant or airflow problem?
Warm air blowing from the vents on a cooling call, ice forming on the evaporator coil, a system that runs constantly without reaching the set temperature, or noticeably weak airflow from the registers are all signs worth calling about. Refrigerant and airflow problems tend to get worse with time, so catching them early usually means a simpler repair.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures are usually caused by duct leaks, blocked or undersized registers, poor insulation in one part of the home, or a system that was not properly sized for the layout. In older Nassau County homes, it can also point to a zone valve issue in a hydronic system. We diagnose the cause before recommending a fix, whether that is duct sealing, a zoning adjustment, or a mini-split for a problem area.
Experienced With Older and Newer Systems
Nassau County's housing stock spans more than a century, and we have worked on all of it. From cast-iron boilers in pre-war colonials to modern heat pump systems in newer construction, we know what we are looking at when we arrive.
How often should I schedule maintenance and tune-ups?
Once a year for each system is the standard. A spring tune-up prepares the AC for summer demand, and a fall tune-up gets the heating system ready before the cold arrives. Annual maintenance keeps equipment running efficiently, reduces the chance of a mid-season breakdown, and gives us a chance to catch small issues before they become expensive ones.
What does a seasonal tune-up actually cover?
A spring AC tune-up includes checking refrigerant levels, cleaning the condenser and evaporator coils, inspecting the condensate drain, and confirming airflow and electrical connections at the equipment. A fall heating tune-up covers the heat exchanger, burners, filters, and controls. We leave you with a clear picture of where the system stands and flag anything that needs attention.
What can cause a system to short-cycle?
Short-cycling, where the system turns on and off every few minutes without completing a full run, is usually caused by an oversized system, a refrigerant problem, a dirty coil or filter restricting airflow, or a failing component like a pressure switch or capacitor. It puts extra wear on the equipment and should be diagnosed before it leads to a larger repair.
Upfront Quotes With No Surprise Fees
We give you a clear cost before any work starts, and we do not add charges without talking to you first. If something changes the scope once we are on site, we explain it and get your approval before moving forward.
Is the installation work permitted and inspected?
Yes. For installations and replacements, we pull the required permits and the work is done to code. That protects you when it comes time to sell the home and ensures the equipment is installed correctly from the start.
What does a strange noise from my HVAC unit usually mean?
Banging or clanking often points to a loose or broken component inside the unit. Squealing can indicate a worn belt or a bearing issue in the blower motor. Rattling may be something as simple as loose panels or as significant as debris in the system. Any new or unusual noise is worth a call, because running a unit with a mechanical problem usually makes the repair more involved.
Workmanship We Stand Behind
Every job we take on comes with a workmanship guarantee. We protect your floors and finishes while we work, we clean up before we leave, and if something is not right, we make it right.
Do I need to be home when the technician arrives?
Someone should be present to let the technician in and to hear the findings before any work begins. We explain what we find in plain language and give you a cost before starting. If scheduling is a challenge, call us and we will work out an arrangement that fits your situation.
How does pricing work, and will I know the cost before work starts?
We discuss costs before any work begins, whether the job is a diagnostic visit, a repair, or a full system replacement. If a technician opens up a system and finds something that changes the scope, we explain it and get your approval before moving forward. The right way to get a number that applies to your specific situation is to call for a quote.
What makes a heat pump a good option for a Lynbrook home?
A heat pump handles both heating and cooling from a single system, which simplifies equipment and can lower operating costs compared to a separate furnace and AC setup. Modern cold-climate heat pumps perform well even in the temperatures Nassau County sees in January and February. For homes moving off oil heat, a heat pump is often a strong candidate alongside a gas-fired replacement. We can walk you through what makes sense for your home's layout and current setup.
Call (363) 999-8289 and we will talk through your system, answer your questions, and get you scheduled for a visit.
