The minimum heat pump requirement on Long Island is SEER2 14.3. This was introduced by the Department of Energy on January 1, 2023. If it’s time to upgrade or install a heat pump, a high-SEER2 unit will be more energy efficient, ensuring comfortable heating with lower energy costs over time.

What is the New SEER2 Rating for Heating Installation?

Heat pump SEER2 is an efficiency rating that replaces the older SEER rating and is more consistent with real-world operating conditions.

• Unlike the older SEER rating, SEER2 considers full-load and partial-load performance to account for seasonal variations. It’s a more comprehensive overview of HVAC efficiency.

The numbers are slightly different, so you can’t directly compare the new SEER2 rating to your older unit. Long Island’s minimum SEER2 14.3 rating is equivalent to an older SEER 15 rating.

Is There a Different SEER2 Requirement for Ducted vs. Ductless Systems?

There is no difference in the federal legal minimum SEER2 rating for ducted and ductless heat pump systems. SEER2 14.3 is a baseline, or the minimum efficiency that you should consider for your home.

In reality, ducted and ductless systems have efficiency variations by design:

• Ducted heating installations are less efficient because they need to move air through restrictive ducts. They use more energy and may lose some thermal energy through the ducts.
• Ductless heating installations are the most efficient because there is no duct resistance. Air is delivered directly to the room.

The right system for you depends on your needs. If you already have ducts, then a central ducted heat pump is the best type of electric heating installation for your home. If you don’t have ducts, adding mini splits for zoned heating in your home will ensure comfort, convenience, and efficiency.

Understanding Cold Climate Performance

Suffolk County winters often hit single digits. Soundview HVAC is a highly-rated Long Island HVAC contractor near you. Our team will ensure that your heat pump system is suited to the climate.

Cold-weather heat pumps can operate in temperatures as low as -13°F, and generally maintain over 70% of heating performance at temperatures around 5°F. Average winter temperatures in Suffolk County range from the low 30s to the low 40s, so your heat pump will typically be operating in its most optimal range.

Heat Pumps Work Better in Well-Insulated Homes

Your home’s insulation (R-Value) is as important as the heat pump you choose.

• A home with a low R-Value of R-11 in the attic (unmodified pre-1980s) is the baseline for heating performance. There are no additional savings, and these homes don’t work well with electric heating.
• An average R-Value of around R-30 to R-38 (Most Mid-90s homes and later) can save around 15% to 20% on heating costs compared to the baseline.
• The most modern homes built to 2026 standards often have an R-Value above R-49, and can save over 30% on heating costs compared to the baseline.

If you are considering switching from gas to electric, your HVAC contractor will consider your home’s design and insulation. If your home has poor insulation, investing in an upgrade, especially in the attic and floor, will ensure significant cost savings and improved comfort.
