Rheem KwikComfort financing, with credit provided by Synchrony Bank, for Long Island homeowners.
Homeowners within 15 miles of Deer Park can finance a new furnace, boiler, central air conditioner, heat pump or ductless system with K2 through Rheem KwikComfort, with credit provided by Synchrony Bank. You apply online or during your estimate, Synchrony Bank sets the terms, and we schedule the installation once you are approved.
When Financing Makes Sense for a Home
Most homeowners who finance with us are in one of three situations. The first is an emergency: a boiler that cracks in January or a central air system that fails in a July heat wave, where waiting to save up is not an option. The second is a planned upgrade, such as replacing a 25-year-old oil boiler or adding a ductless mini-split to rooms the original system never reached. The third is a whole-home change, such as moving from oil to a cold-climate heat pump, where spreading the cost makes a better long-term choice affordable now.
In each case we start with an honest repair-or-replace assessment. If a repair makes more sense than a new system, we will tell you, and many repairs do not need financing at all.
Equipment Homeowners Commonly Finance
- Central air conditioners sized with a Manual J load calculation, including replacements for undersized or failing systems; see AC installation
- Gas and oil furnaces, hot-water and steam boilers, and combination boilers that also supply hot water; see heating installation
- Single-zone and multi-zone ductless mini-splits for additions, attics, sunrooms and homes without ducts
- Ducted and ductless cold-climate heat pumps, often with the existing boiler kept as backup
- Whole-home indoor air quality equipment and major repairs

Planning Your Project
Once you are approved and accept the estimate, we schedule the installation based on equipment availability and our schedule at the time. Most furnace, boiler and central air replacements take one to two days; multi-zone ductless and oil-to-heat-pump projects can take longer. Many Long Island towns and villages require a permit for new heating and cooling equipment. K2 does not file town permits, so confirm the requirements with your building department before the installation is scheduled.
If you are replacing an oil system, think about the oil tank and the chimney early. A tank that is no longer needed must be removed or properly abandoned by a licensed tank contractor under county rules, and a new high-efficiency appliance may vent differently from the old one. We explain these steps during the estimate so the financed amount covers what the project actually needs.
Rebates and Financing
Rebates and financing are separate. Qualifying cold-climate heat pumps may be eligible for PSEG Long Island Clean Heat rebates, which are claimed through a PSEG Long Island participating contractor or directly with PSEG Long Island; amounts and eligibility change, so confirm current terms at psegliny.com. K2 is not a PSEG participating contractor and does not file rebate applications. See our main financing page for how KwikComfort works in more detail.

Do I need financing approval before getting an estimate?
No. We can visit, assess your home and give you a written estimate first. Many homeowners apply once they know which system they want and what it will cost.
Can I finance a repair instead of a new system?
Major repairs, such as compressor or heat exchanger work, can be financed, subject to approval. We give you an honest repair-or-replace recommendation first, and smaller repairs are usually paid directly.
How long after approval can the work start?
We schedule the installation once you are approved and have accepted the estimate, based on equipment availability and our schedule at the time. We do not promise specific installation dates, but we will give you the expected timing when you book.
