Why Work With Universe Home Services?

Seven decades of HVAC service across Long Island means we understand what works in Nassau and Suffolk County homes and what does not, including where ductless systems are the right answer and where they are not. That experience shapes every recommendation we make.

When a ductless system stops cooling in July or stops heating in January, you do not want to wait a week for a diagnostic. We respond quickly and work efficiently to restore comfort to the zones the system covers.

Our HVAC technicians are skilled, certified, and experienced across ductless mini split systems, including single-zone and multi-zone configurations from the major manufacturers. Every installation, repair, and tune-up is handled by someone who knows the equipment and the refrigerant handling it requires.

From heating and cooling to plumbing and electrical, we offer a full range of services to support your home’s needs. That matters on ductless projects where the installation touches the electrical panel, the exterior wall penetration, and the condensate line all at once.

We take the time to explain your options and provide straightforward recommendations so you can make informed decisions. If a repair solves the problem, that is what we recommend, not a replacement that is easier to sell.

Every job is completed with attention to detail and a focus on long-term performance, including clean refrigerant line routing, proper condensate drainage, and tidy electrical runs. The install has to look right and perform right for years, not just on commissioning day.

We treat your space with care, keeping work areas clean and minimizing disruption during every service. Ductless installations involve wall penetrations and line hide runs that are visible after the job is done, and we take the finish seriously.

As a trusted name on Long Island, we are committed to delivering dependable service and building lasting relationships with our customers. Homeowners across Nassau and Suffolk County rely on us because we know the homes here and we show up when we say we will.


An Easy, Stress-Free Scheduling Process

Getting ductless HVAC help should never feel complicated.

Universe Home Services makes the entire process easy from start to finish, so you are always able to get the help you need.

Call us or schedule service online at a time that works for you. We will gather a few details about your home, your existing system if there is one, and the comfort concern driving the call, then get your appointment set quickly.

Our technician assesses your space, your existing equipment or installation site, and the comfort zones you want to address. You receive a clear walkthrough of your options with honest recommendations and upfront pricing before any work begins.

We complete the work efficiently and with care, testing the system in both heating and cooling modes where applicable and verifying your home is comfortable before we leave. You get a ductless system that performs the way it was designed to.

Follow-up rating! 5 stars to Nick Serafino our tech who came out when we discovered water leaking from AC drain piping. He was super knowledgeable and a fast technician. Very happy with the service . Definitely recommend calling Universe Hone Services.
What fantastic service! First time using them for HVAC spring tune up and was very impressed! My technician Chester was very polite, thorough and a pleasure to deal with. Definitely will recommend them to anyone looking for a Home repair/service company. Very affordable and was easy to get an appointment. I would give them 10 stars if I could. Especially Chester !
I had Peter McAdam come and service our AC. He came ready with tools in hand, he was very professional and polite and courteous. He was very knowledgable and able to get my AC working. Highly recommend.
Extremely thoughtful and considerate of my property.

Efficient and personable
Peter is excellent. I'd give him 10 stars if I could
Great service. Knowledgeable professional courteous
Our techs were courteous and thorough in their approach to checking and restoring our tankless water heater system and our HVAC system more recently. The yearly Home Comfort membership program was helpful in keeping the tech fees lower or free and securing immediate service.
Nick S. came to do the yearly service for my air conditioning. Nick is great and very up front which I like. After almost 17 years I need a new system. Ugh! He brought me outside and showed me all the reasons why it should be replaced. I could wait & see but didnโ€™t want to risk it so Saturday Iโ€™ll be getting a new system. It just needs to be done. I was very happy Nick explained everything to me. Heโ€™s very knowledgeable & friendly.

I would also like to acknowledge the following employees from Universe who all had some part of the installation of my furnace, compressor and humidifier. Everyone who came to my house were so friendly and respectful. The guys all explained what was being done. They also installed an Air Scrubber which purifies my system of spores, etc. The employees are Tommy Ercolano, Matt Drury, Carlos Caceros, Justin Quan-Soon, Jamell Smith and Karl Rindfleisch. All were fabulous. And I can't forget Chester Sacknievich who came back to fix an issue I was having and figured out the solution. Chester is great.

I highly recommend Universe. Their employees go above and beyond!!
Jamie is the man! I reached out to Universe Home Service towards the tail-end of my research process to install a new 2-zone mini-split system in my home. i only learned about Universe after reading an unsolicited recommendation from someone on Reddit. I already had proposals/bids from 3 other vendors by the time Jamie visited my home. He did a good job of explaining things and answered my multiple questions (with logical explanations) which helped me to reach my decision. At the end of a two week process I decided to engage Universe to perform the work and I can honestly say Jamie was a big factor in my decision. The installation is scheduled for the end of this week and I will post another review regarding how that process went afterwards.
Very knowledgeable guys.
Repaired rattling pipes.
I am always happy with the professionalism and politeness of their technicians. Itโ€™s a real peace of mind.

Ductless Mini Split Installation

Adding a ductless system gives you control over comfort in spaces traditional systems cannot reach.

We design each installation around your home’s layout, making sure every indoor head is positioned for maximum effectiveness and every refrigerant line is routed cleanly. Our team handles everything from mounting to condensate management to system commissioning, so nothing is overlooked. You are left with a clean install and dependable comfort right where you need it.

Choosing the right size system is essential for performance and efficiency. A unit that is too small will not keep up on the hottest summer days or coldest winter nights, while an oversized system short cycles, wastes energy, and fails to remove humidity the way a correctly sized unit would.

Where the indoor heads are installed directly affects comfort and airflow across the zone. Proper placement avoids hot or cold spots, keeps the unit away from furniture and window lines, and uses the room’s geometry so the conditioned air actually reaches every corner.

Ductless systems allow for zoned comfort, but the right number of zones depends on how the home is actually used. A single-zone system handles one room efficiently, while a multi-zone outdoor unit serving three or four heads gives a whole floor or an addition its own independent control.

Ductless systems require a dedicated circuit and the right installation conditions. On older Nassau County homes with 100-amp panels, the electrical scope may include a panel evaluation before the install can move forward, and we handle that scope in-house.

Ductless Mini Split Replacement

Older ductless systems lose efficiency and struggle to keep up over time.

We guide you through selecting a replacement that improves performance while lowering energy use, and we handle the transition carefully to minimize disruption to your home. Once installed, you notice more consistent temperatures, better dehumidification in summer, and better cold-weather performance from a modern cold-climate-rated system.

If your system struggles to maintain consistent temperatures or no longer keeps up with demand on the hottest or coldest days, it may be losing effectiveness due to age, refrigerant loss, or compressor wear. Replacement restores performance with a newer, more capable unit.

Needing repairs more often than usual is a strong indicator the system is nearing the end of its lifespan. Replacement eliminates ongoing service costs and provides a fresh service life with updated technology and manufacturer warranty coverage.

An older or inefficient system uses more energy to do the same job. If your utility bills are climbing without a clear weather or usage explanation, an aging ductless unit running above its rated draw is a likely cause.

Strange sounds from the outdoor unit, persistent musty odors from the indoor heads, or both at once can signal internal issues that are not always worth repairing on an older system. Replacement is often the more reliable long-term solution.

Ductless Mini Split Repair

When something feels off with your ductless system, it is usually a sign it needs professional attention before the problem grows.

We take a diagnostic-first approach, pinpointing the issue before making any repairs so you are not paying for parts that were not the root cause. Our goal is to restore proper function quickly, whether the problem is at the indoor head, the outdoor condenser, the refrigerant lines, or the control board. We can help with:

Addressing issues right away brings your home back to a comfortable temperature without long disruptions, which matters most during a summer heat wave or a January cold snap when the ductless system is the primary source of comfort for its zone.

Small issues turn into major system failures if left unchecked. A minor refrigerant leak, a failing capacitor, or a clogged condensate drain all get worse until they force a shutdown, and prompt repair stops that progression before it spreads.

A system that is not working properly draws more energy to deliver less comfort. Fixing the problem early restores efficient operation and brings the unit back to the energy use it was designed for.

Taking care of repairs as they arise reduces strain on the compressor and the rest of the system, helping the unit last longer and perform more reliably across the years it should be running.

Ductless Mini Split Maintenance

Keeping your ductless system in top shape takes more than occasional use. It takes routine care.

During maintenance visits, we clean the indoor head filters and coils, check the condensate drain, verify refrigerant charge, and inspect the outdoor unit for debris, corrosion, and electrical integrity. This proactive approach keeps the system running efficiently through both heating and cooling seasons and catches small issues before they become service calls.

Regular maintenance keeps your system running at peak performance, so it uses less energy to heat and cool your home. A clean filter and a properly charged system can be the difference between a ductless unit running at rated efficiency and one working noticeably harder to deliver the same comfort.

Routine service catches small issues early, before they turn into costly or inconvenient system failures. A loose electrical connection, a clogged condensate line, or a dirty coil is a five-minute fix at a tune-up and a much bigger problem six months later.

Keeping components clean and properly adjusted reduces wear and tear, helping your system reach or exceed its expected service life. Salt air from Long Island’s coastal proximity accelerates corrosion on outdoor units, and regular maintenance is how that exposure gets caught and managed before it shortens the system’s life.

Cleaning filters and internal components reduces dust, allergens, and buildup, leading to cleaner air throughout the zones your ductless system serves. On mini splits, the indoor head is effectively the air handler for the room, so filter and coil cleanliness has a direct effect on what you are breathing.

Ductless Mini Split FAQs

How long do ductless mini split systems last?

Most ductless systems last between 15 and 20 years with proper maintenance. Regular service extends the lifespan and maintains performance across that window, and on Long Island, where salt air accelerates corrosion on outdoor units near the coast, consistent maintenance is how the system reaches the top of that range instead of the bottom.

Are ductless mini splits energy efficient?

Yes. Ductless systems are known for their high efficiency because they do not lose energy through ductwork, and many models offer inverter-driven compressors that ramp output up and down to match the load rather than cycling hard on and off. That efficiency shows up as meaningful savings on utility bills, especially on homes replacing window units or electric resistance heat in the same zones.

How many indoor units do I need?

The number of units depends on your home’s layout and how many areas you want to control. A professional assessment helps determine the right setup, whether that is a single-zone unit for a specific room or a multi-zone system covering several spaces from one outdoor condenser. We size the system to the home you actually have, not a generic square footage target.

Do ductless systems provide both heating and cooling?

Yes. Most ductless mini splits are heat pumps that provide both heating in the winter and cooling in the summer. Modern cold-climate-rated models perform well through Long Island winters, and qualifying heat pump installations may also be eligible for rebates through the New York State Clean Heat Program.
