What is a commercial rooftop unit?
A commercial rooftop unit is an all-in-one heating and cooling system for commercial or multifamily buildings that can be installed on a building’s roof. These systems provide cooling, heating, air filtration, and ventilation, and connect to the building’s existing ductwork. As these RTUs can be easily zoned, they are perfect for retail spaces, food service buildings, and workspaces. Each RTU has compressors and coils, a blower fan to move the heated or cooled air, and heating elements and air filters on board. The typical RTU covers between 400 and 500 square feet per 1 ton of cooling capacity, and commercial rooftop units range from 3 to over 100 tons of cooling capacity per unit.
What are the Benefits of a Rooftop Unit?
Rooftop Unit Installation, Repair, & Replacement Company in Ann Arbor, MI
RTUs have a ton of benefits to building owners and tenants alike. For instance, as the compressors and fans are on the roof, heating and cooling operations are quiet and will not interrupt normal operations or disrupt tenants. As rooftop units can clean, heat, cool, and filter the air circulating within the building, the building itself will be cleaner, with less dirt and debris moving through the ductwork. On top of this, RTU installation and maintenance are straightforward, as your commercial HVAC technicians will only need roof access to complete the job. Finally, one of the biggest benefits for our clients is the cost savings that come with installing a rooftop unit. The initial capital investment can be significant, but operating with a single unit that handles both heating and cooling will help lower your building’s operating costs over time and streamline repairs and maintenance visits.

Types of Rooftop Unit Systems in Ann Arbor
There are five core types of RTUs, along with a variety of operational configurations to choose from.
There are more than a handful of commercial rooftop units that are on the market today. With options from Schneider, ABB, Siemens, Carrier, Trane, and York, today’s RTUs are not only efficient but also among the best capital investments you can make in your building.
- Cooling-Only
Cooling-only RTUs are similar to larger air conditioners because they lack a built-in heating function. These RTUs are perfect for those who are just looking for a cooling solution for their multifamily or commercial building or for buildings with high internal heat loads where only cooling is needed.
- Gas/Electric Packaged Units
Gas/Electric packaged units are the most popular RTUs due to their flexibility for heating and cooling. These units use electrical refrigeration for cooling and are paired with a natural gas- or propane-powered furnace for heating.
- Heat Pump Rooftop Units
Commercial rooftop heat pump units use a reversing valve system to move heat to and from the building, providing heating and cooling. These systems are purely electric and have grown in popularity over the years due to their relatively low operating costs.
- Hybrid Systems
Hybrid systems, also known as dual-fuel systems, combine the efficiency of an electric heat pump with a gas furnace. These systems are a great fit for Ann Arbor, MI, as they can handle the frigid winters while also providing maximum energy efficiency by balancing the gas furnace and the electric heat pump.
- 100% Outside Unit
100% outside units, or make-up air units, draw in fresh air and replenish the exhaust air to manage the building’s pressure. These DOAS units are great for larger buildings and can be a cost-effective HVAC solution for larger buildings and multi-use complexes.

HVAC Services
We can handle all aspects of heating and cooling, including furnaces, A/C, and split units. With a focus on eco-efficiency and smart installations, our HVAC services will help bring improved indoor air quality through a well-thought-out vent and duct design customized to your layout.

Your Commercial Rooftop Unit FAQs...
Answered by FRY!
How often do I need to maintain an RTU?
According to Fry professional HVAC technicians you should look to do routine inspections and maintenance services on your RTU at least once a year. However, depending on your specific equipment and warranty, you may need maintenance more often than that.
What RTU is right for my building?
There is no one-size-fits-all approach to RTUs, but due to their modular designs, Fry can provide you with a detailed and well-thought-through heating and cooling load calculation to determine what RTU is right for your needs.
Do I need a separate air conditioning and heating RTU?
No, the beauty of a rooftop unit is that it can heat and cool from a single unit. So, there is no need for separate air conditioning and heating when you invest in an RTU. Plus, RTUs can even do single and multi-zone heating, making them a versatile piece of tech that will be perfect for your building.
How are rooftop units installed in Ann Arbor, MI?
Our installation methods will depend on the specific building that we are working on. However, in general, our installation process involves using a mobile crane to move the rooftop unit into position and install it on the roof. Our HVAC technicians and electricians will install it perfectly and connect it to your duct and electrical systems in no time.
How does a rooftop unit provide both heating and cooling?
Rooftop units use the same process as a commercial furnace and air conditioner, combining them into a single unit. For dual-fuel systems, a gas furnace and an electric heat pump are included in the RTU. For gas-and-electric packaged units, these RTUs use a propane or natural gas furnace and an electric air conditioning unit.
What types of commercial buildings are best suited for rooftop units?
RTUs are a flexible, all-in-one solution that are a perfect fit for single-story or low-rise commercial buildings. An ideal building for a rooftop unit should have a strong load-bearing flat roof, be between one and ten stories and have an open layout that would benefit from high-volume airflow for heating and cooling.
Can rooftop units be zoned for different areas of a building?
Yes, you can zone a rooftop unit with ease. For zoning, the team at Fry will install motorized zone dampers that will open and close automatically to regulate airflow. To enable zoning, each zone is assigned a local thermostat with individual sensors, all controlled by a central control panel to properly align damper positions and modulate the RTU’s output to keep the room at the ideal temperature.
