Commercial Packaged Rooftop Units

Designed with streamlined installation in mind, Day & Night commercial packaged rooftop units have everything you need from handled access doors to certified and pre-engineered factory-installed options as well as field-installed accessories.

Day & Night rooftop units are available in gas heating/electric cooling or packaged heat pumps and deliver SEER ratings as high as 13.4 and EER ratings up to 11.3 on standard efficiency units and SEER ratings as high as 15.8 and EER ratings up to 12.4on high efficiency models.

Day & Night rooftop units have the capability for vertical or horizontal airflow for fast and easy installation. The high-efficiency gas heating (up to 82% efficiency) with induced draft design facilitated long life and safe operation. Day & Night rooftop units can easily satisfy any light commercial application need.

Easy To Service – Scroll Compressor
Day & Night rooftop units utilize fully hermetic scroll compressors.

Compressors are designed with internal isolation and have internal thermal line break, current overload, and high-pressure differential protection.

Central Terminal Board
The integrated terminal simplifies the installation of pre-engineered and certified field-installed accessories including economizers by providing clearly labeled connection points for easy plug-in connection. It is standard on every unit.

Easy Access Handles
Handles located on all major access panels provide quick, convenient and safe access to components for easy maintenance and service.

No-Strip Screw Collars
To prevent misalignment and stripped metal panels, screws are guided into collars. The addition of these Screw Collars makes panels faster and easier to remove and install.

Unit Safety Protection
Heat pump models come standard with a refrigerant suction line accumulator in each refrigerant circuit. This preventative measure interrupts the natural tendency of liquid refrigerant from entering the compressor in heat pumps as they switch in and out of defrost and between heating and cooling modes. This dramatically increases the reliability of Day & Night heat pump units. In addition, heat pump models come with high pressure and temperature protection as well as low pressure or loss of charge protection.

When Should You Repair Your Unit?
When your heating and cooling system is working properly, your building is comfortable and you’re probably not experiencing any significant increase in your utility bills. So when a part malfunctions or your unit stops working, how do you decide if it’s time to repair or replace it? Your local Day & Night® dealer can provide a thorough diagnosis of your system and make a professional recommendation. To help you decide, we’ve put together a list of factors to consider.

Here are some reasons to repair the unit:

  • The cost of repairs is less than one-third the cost of a replacement
  • The unit is less than 10 years old

The unit is still under warranty (see your warranty terms)

When Should You Replace Your Unit?
Replacing all or part of a heating and cooling system can be a big investment. When an older unit has continuous issues or shows signs of reduced energy efficiency, it could be more economical to upgrade your HVAC system. A Day & Night dealer can help you diagnose your heating and cooling system, as well as help you choose a replacement that fits your needs and budget.

Here are some reasons for replacing your heating or cooling unit:

  • The cost of repairs is near 50% of the cost of a replacement
  • The unit requires frequent repairs.
  • Humidity problems that signal operating issues
  • Warranty expirations
  • High dust and low air quality problems

The furnace is more than 15 years old, and the heat pump or AC is more than 10 years old

Air Quality
Pollutants are everywhere indoors and are frequently two to five times more prevalent than in outdoor air. Day & Night high-efficiency air purifiers help you breathe easier by treating 100% of the air flowing through your building’s comfort system with their patented technology that both filters and kills or inactivates airborne irritants, such as pollen, pet dander and other air irritants.

The summer months bring hot and muggy temperatures in many parts of the country. Day & Night multi-stage heat pumps and air conditioners offer enhanced dehumidification to ensure that extra moisture doesn’t stick around. Day & Night’s efficient furnaces with variable-speed blowers also help pull moisture out of the air during the cooling season.

Day & Night® products includes the extra care and technology to create quiet operation for your office or home. From design to operation, sound reduction ensures a comfortable experience with your heating and cooling systems. Day & Night products deliver low decibel sound levels and sound-barrier technology to create a relaxing comfort experience.

The Observer wall control allows you to customize temperature, humidity and fan speed in up to six zones of your office or home. The Smart Recovery feature smoothly and efficiently adjusts zones to your customized comfort levels throughout the day and week.

Remote Access
Convenience and versatility are key to Day & Night complete comfort systems. Our Observer® wall control with Wi-Fi® capability provides the ideal way to control your home or office comfort from your computer or mobile device. Simply access your Internet browser and log on to our easy-to-use, personalized Web portal that displays just like the Observer control to adjust your comfort.

Programmable Control
Set your preferred temperatures throughout the week with our Observer® communicating control with advanced touchscreen technology. Our seven-day programming lets you set different temperatures for different times of day for the ultimate comfort control.

Variable Speed
When you combine a Day & Night variable-speed product with an Observer® communicating control, you have more control over the comfort and humidity in your office or home. Variable speed is different than single speed because it can move air at optimal speeds to keep the temperature in your office or home more consistent, minimize hot and cold spots and also increase efficiency and air quality.

Energy Savings
Day & Night® products are made with energy efficiency in mind. If your units are 10–15 years old, you may be paying an extra 20% or more than you need to for your heating and cooling.
Newer products are governed by higher energy efficiency standards created by the Department of Energy (DOE), and the Environmental Protection Agency (EPA) promotes high efficiency products through its ENERGY STAR® program.

All Day & Night® heating and cooling products currently meet or exceed the DOE minimum efficiency standards. We offer ultra-high efficiency products that exceed the minimum qualifications of the ENERGY STAR program. And many of our product lines are ENERGY STAR qualified with some of the highest efficiency products available today.

Total Cost Savings
The total savings of your current system and a new one depend on many factors such as the weather where you work or live, utility costs, your building’s energy efficiency, and your temperature setting preferences.

Many state governments and utility companies offer incentives for installing energy-efficient heating and cooling units. Incentives vary widely, but typically include tax credits, low interest loans, grants and rebates.

In warmer climates or areas with higher electric costs, most buildings can benefit from a higher-SEER cooling unit. In colder climates or areas with higher fuel costs, a higher-AFUE gas furnace can be more economical. You may be able to compare annual operating costs of two systems just by knowing their efficiency ratings. Here are the measurement standards the DOE has provided for measuring efficiency:

Glossary of Terms
AFUE Rating: Gas furnaces use Annual Fuel Utilization Efficiency (AFUE) as their measurement. The higher the AFUE, the greater the efficiency and the greater your energy savings potential.
HSPF: Heat pumps use Heating Seasonal Performance Factor (HSPF) as their measurement of heating efficiency. The higher the HSPF, the greater the efficiency and the greater your energy savings potential.
SEER: SEER stands for Seasonal Energy Efficiency Ratio and applies to central air conditioners and heat pumps during cooling operation. The higher the SEER, the greater the energy economy.
EER: EER stands for the Energy Efficiency Ratio that calculates the efficiency provided by a central air conditioner or heat pump while cooling at a specific outdoor temperature. It can be found by dividing a unit’s Btu output by its wattage.
ENERGY STAR® : ENERGY STAR® qualified earn the U.S. government’s designation for superior energy efficiency to help save costs on energy bills.
Decibel (db) : Unit used to measure sound level by comparing it with a given level on a logarithmic scale.
