WHAT SETS DAY & NIGHT® AIR CONDITIONERS
AND HEAT PUMPS APART?
1. Durable galvanized steel construction with baked-on paint finish weathers
seasonal extremes.
2. Post-painted fin stock and coated wire grille guard against corrosion.
The grille spacing protects the coil but allows for easy cleaning.
3. Scroll compressor operates with proven efficiency and reliability.
4. Control panel allows for easier, quicker service access.
5. Compressor is housed in an extra-thick shell for added protection
and durability.
6. Top-discharge design improves airflow and minimizes noise.
7. Durable copper tubing, aluminum fin coil, and fins that are post-painted
for protection help maintain efficiency.
8. Integrated solid state controls make the change from heating to cooling go
smoothly. (Heat pump only)

EFFICIENCY RATINGS—WHAT DO THEY MEAN?
Minimum Air Conditioner Efficiencies
Seasonal Energy Efficiency Ratio (SEER)—Measures the
cooling efficiency of air conditioners and heat pumps during an
average cooling season. The higher the SEER, the greater the
energy economy.
13 SEER
Heating Seasonal Performance Factor (HSPF)—Measures
the heating efficiency of heat pumps. The higher the HSPF, the
greater the efficiency and energy savings potential during heat
pump heating.
14 SEER+EER*
14 SEER
Energy Efficiency Rating (EER)—Measures the cooling
efficiency of air conditioners and heat pumps during a set
temperature (95° F).
ENERGY STAR —A U.S. Environmental Protection Agency
program to identify and promote energy-efficient products in order
to reduce energy consumption.

On January 1, 2015, a new set of minimum efficiency standards took effect. Under the new standards,
there are different efficiency minimums for air conditioners in each of three regions—North, Southeast
and Southwest. The national minimum efficiency standard for heat pumps is 14 SEER/8.2 HSPF.

Many models are ENERGY STAR® qualified. Proper sizing and installation of equipment is critical to achieve
optimal performance. Split system air conditioners and heat pumps (excluding ductless systems) must be
matched with appropriate coil components to meet ENERGY STAR criteria. Ask your contractor for details or
visit www.energystar.gov.
Timely registration required for 10-year parts limited warranty. Limited warranty period is 5 years for parts if not
registered within 90 days of installation. Jurisdictions where warranty benefits cannot be conditioned on registration
will receive the registered limited warranty periods. Please see warranty certificate for further details and restrictions.
