Our HVAC Replacement Process
Replacing your HVAC system is a major decision, and Universe makes sure you have the information you need at every stage. Here is what replacement looks like when Universe handles it.
A technician comes to your home and looks at what you actually have: your current equipment, fuel source, ductwork condition, and how your home is laid out. Nassau County homes built in the 1950s and 1960s often have ductwork that was never designed for modern HVAC output, and that affects what system goes in. You receive upfront pricing with a clear explanation of what goes in, what it costs, and why it fits your home. Same-day and emergency scheduling are available for situations that cannot wait.
Licensed HVAC technicians handle the full replacement from start to finish, covering gas or oil connections, electrical, ductwork, and controls to manufacturer specifications and local codes. Gas or oil connections, ductwork, and electrical are all handled to manufacturer specs, and the work area is restored before the crew leaves.
Once installed, your system runs through a complete heating and cooling cycle to confirm reliable operation. Before we close the job, your system runs a full heating and cooling cycle and your technician confirms output matches what your home’s load requires.

What Changes When You Replace Your HVAC System
An aging HVAC system costs you every month it keeps running.
Long Island homeowners pay some of the highest energy costs in the country between PSEG electricity rates and fuel oil prices. A system that has aged past its efficiency peak is making an already expensive situation worse every month. A correctly sized replacement running at rated efficiency closes that gap from the first billing cycle.
If you have a bedroom that never gets cool in August or a back room that stays cold all winter, that is a system performance problem, not a structural fact of life. A replacement assessed against your home’s actual load and ductwork fixes uneven distribution. An HVAC system installed correctly for your home’s load reaches the thermostat setting and holds it, in every room.
Most HVAC failures happen at the worst possible time: the first cold snap of November, the hottest week of July. A new system with a manufacturer warranty behind it removes that uncertainty. You stop managing something that is running on borrowed time.
A significant share of Nassau County homes still run on oil heat. Replacement is when most homeowners make the switch to gas or a heat pump. You eliminate the delivery calendar, the tank on your property, and the exposure to oil price volatility in a single job. Universe handles the full conversion as part of the replacement.

Why Long Island Homeowners Choose Universe for HVAC Replacement
The company you choose for your HVAC replacement determines whether the job is done right and whether you have someone to call afterward.
Universe has been replacing HVAC systems in Nassau and Suffolk County since before most of the homes we work in were built. That longevity is earned.
Gas furnaces, oil furnaces, central AC, heat pumps, oil-to-gas conversions: your technician has done all of it in Nassau and Suffolk County homes. Long Island’s coastal salt air accelerates corrosion on outdoor equipment, and our technicians account for that during installation. Your technician has done this in Nassau and Suffolk County homes enough times that nothing about the job is unfamiliar.
Universe has been replacing HVAC systems in Levittown, Hicksville, Massapequa, and across Nassau and Suffolk County since 1954. Decades of HVAC work in Nassau and Suffolk County gives your technician a reference point for what these homes typically present and what solutions actually hold up.
No charge for the estimate. It covers your home’s actual heating and cooling load, your existing ductwork and fuel source, and all available options. You have the full picture on cost and system fit before a single appointment is booked.
HVAC replacements frequently surface related issues: an undersized electrical panel that needs upgrading before the new system can run, or plumbing work tied to the mechanical room. Universe covers all three trades. One call handles it.
HVAC systems fail at the worst times. Universe schedules same-day HVAC replacements for situations that cannot wait and maintains 24/7 emergency coverage throughout Nassau and Suffolk County. Levittown, Garden City, Smithtown, Lindenhurst: the same crew availability regardless of where you are on the island.
National Grid rebates apply to many HVAC installations, especially oil-to-gas conversions and high-efficiency equipment upgrades. Universe determines what National Grid rebates and energy incentives apply to your specific installation and manages the submission so you do not have to. You do not leave money on the table.
When your HVAC system is in and running, Universe stays your point of contact for service, maintenance, and any follow-up questions. Questions, service needs, maintenance scheduling: the same company that installed your system is the one you call.
Keep Your New System Running with the Home Comfort Club
A new system is worth maintaining properly from the start.
Most HVAC failures that become emergency calls started as something a fall or spring tune-up would have caught: a heat exchanger showing early stress, a capacitor near the end of its service life, a filter so restricted the system is working against itself.
The Home Comfort Club schedules those visits automatically, one before heating season and one before cooling season, before small issues become failures.
Members also get priority scheduling, a discount on repair work, a credit toward a new system installation, and no dispatch fee when work is performed. Contact us to learn what the membership covers.

Is It Time to Replace Your HVAC System?
Most systems give you a window before they fail. These are the signals to take seriously.
HVAC systems typically last 15 to 20 years, and Long Island’s coastal salt air accelerates wear on outdoor components. Many Nassau County homes built during the postwar era are still running equipment that is well past that window. A system at that age is not just losing efficiency. It is carrying real failure risk through every heating and cooling season that passes.
When the cumulative cost of keeping an aging system running approaches what a replacement costs, the financial calculation has already shifted. Homeowners in Merrick, Seaford, and Wantagh who schedule HVAC service every year are often past that threshold without realizing it.
When your bills keep rising with no change in how you use the system, your HVAC equipment is losing efficiency. On Long Island, where PSEG rates and fuel oil prices are among the highest in the country, that efficiency gap costs real money every month.
An HVAC system that runs constantly without bringing your home to the thermostat setting in August or January has stopped meeting your home’s demands. In Nassau County homes that have had additions or reconfigured layouts, an undersized or degraded system makes this problem worse with every passing season.

Frequently Asked Questions
Do I need to replace both the furnace and the AC at the same time?
Not always, but it is worth a serious conversation. If one system is significantly older or in worse condition than the other, replacing just the failing unit is reasonable. But when both are approaching 15 years, replacing together usually makes more financial sense: one installation, one set of permits, one disruption to your home. Your technician will give you an honest read on where each system stands before recommending anything.
What size HVAC system does my Long Island home need?
Sizing is calculated, not guessed. A technician performs a load calculation based on your home’s square footage, insulation quality, window placement, ceiling height, and ductwork condition. Many Long Island homes built in the postwar era have had additions or layout changes that affect what the current system can actually deliver. Installing an oversized system causes short-cycling, uneven temperatures, and premature wear. Installing an undersized one means your home never reaches the thermostat setting.
How long does an HVAC replacement take?
Most replacements are completed in a single day. Oil-to-gas conversions or installations that require electrical panel work may take longer depending on what is involved. Universe plans each job in advance so your home is not left without heat or cooling overnight when it can be avoided.
What HVAC rebates are available to Long Island homeowners?
National Grid offers rebates on qualifying high-efficiency heating and cooling equipment, and NYSERDA incentives may apply depending on the system tier and your home’s current setup. Oil-to-gas conversions often qualify for additional programs. Universe identifies what applies to your specific installation and handles the paperwork so you are not leaving money on the table.
