Stop settling for a 17-week pool season
An unheated Long Island pool is only truly comfortable for part of the summer. A heater changes that.
Here on the South Shore, the water is warm enough to enjoy for a surprisingly narrow window. You wait all spring for it to warm up, get a few good months, then watch it cool off before Labor Day is even behind you.
A properly sized heater adds weeks on both ends — swim earlier in the spring and later into the fall. And on cool evenings or a chilly spa night, you get warm water on demand instead of waiting on the weather. The right heater depends on how you want to use your pool, which is exactly what we sort out next.
Choose Your Heater
Which pool heater is right for you?
Two great options for two different priorities. Here's the honest breakdown.
Lead option — season extension
Heat Pump
A heat pump pulls warmth from the air to heat your pool, which makes it most efficient in the spring and fall shoulder temperatures — exactly when you want those extra weeks.
- ✓ Best for extending the season efficiently
- ✓ Lower running cost over a long season
- – Heats gradually and needs adequate electrical service
Fast heat / spa / on-demand
Gas Heater
A gas heater heats fast regardless of the air temperature — ideal for spas and for homeowners who want to heat it now rather than run a heater constantly.
- ✓ Fastest heat-up, great for spas and quick sessions
- ✓ Works in any temperature
- – Higher run cost; needs a gas supply (natural gas or propane)
Our honest recommendation: for most Long Island homeowners who want a longer season, a heat pump is the smart anchor. If fast spa heat or on-demand warmth is your priority, gas is the answer. We'll confirm the right fit during your on-site visit.

Local Expertise
Built for Eastern Long Island conditions
Our climate is the whole reason heaters pay off here. The spring-and-fall shoulder window is when a heat pump does its best work, turning cool-but-close weather into real swimming days.
Gas availability varies across the South Shore — some properties have natural gas, others run on propane — and heat pumps depend on your home's electrical service. Equipment-pad layouts on typical Eastern Suffolk properties also affect placement. Knowing all of this locally is what lets us size and site the heater right the first time.
How much does a pool heater cost?
Rather than quote a number that turns out to be wrong, here's what actually drives the price:
- + Heater type (heat pump vs. gas)
- + Pool size and water volume
- + Any new gas line or electrical work required
- + Placement on the equipment pad
- + Brand and unit capacity
The on-site visit produces your exact number — and it's worth weighing against what you get back: more usable weeks in the water every single year.

Pool heater FAQs
Gas heater vs. heat pump — which should I get?
It depends on how you use your pool. A heat pump is the efficient anchor for extending the season — it pulls heat from the air and costs less to run over a long season, but heats gradually. A gas heater heats fast and is ideal for spas or 'heat it now' use, but costs more per hour to run and needs a gas supply. During the on-site visit, Kevin will recommend the right fit for how you actually swim.
How much does a pool heater cost on Long Island?
The total depends on the heater type, your pool's size and volume, any gas line or electrical work needed, placement on the equipment pad, and the brand. Because those factors vary from yard to yard, we give you an exact, written quote after the on-site assessment rather than a guess over the phone.
How many extra weeks of swimming will a heater add?
A heater comfortably adds several weeks on both ends of the season — swimming earlier in spring and later into fall — turning a short Long Island summer into a much longer usable season. The exact gain depends on the heater, your target temperature, and how much wind and shade your pool gets.
How long does a heater installation take?
Most straightforward installations are completed in a day once the unit is on hand and any gas or electrical work is prepared. Jobs that need a new gas line, an electrical upgrade for a heat pump, or equipment-pad changes can take longer — we scope that during the assessment so there are no surprises.
Do I need a permit for a pool heater in Suffolk County?
Permit and inspection requirements vary by township, especially for gas and electrical work. We handle permits and code-compliant connections where they're required so the install is done right and passes inspection.
Can you replace or repair my existing heater?
Yes. We replace failed or inefficient units and repair heat pumps and gas heaters across all major brands. If a repair is the smart call, we'll tell you — we don't push a replacement when a fix makes sense.
Will a heat pump work in spring and fall here?
Yes — the spring and fall shoulder seasons are exactly where a heat pump shines on Eastern Long Island. It's most efficient in the milder air temperatures of those months, which is when most homeowners want those extra swimming weeks.
