What is an rooftop unit?

Many buildings – apartments, businesses, etc – use rooftop units for heating and cooling. They usually come with all the amenities: heating, ventilating, air conditioning, and anything in between, granting them the abbreviation HVAC. They’re usually referred to as an “air handling unit”, or “air handler”, (abbreviated to AHU) that contains the HVAC system. The air handling unit contains a blower, heating or cooling elements, a filter rack or chamber, dampers, and sound attenuators. They come in many different sizes, the larger ones usually used in commercial buildings such as schools or office buildings, and smaller ones can be used for private homes, like A/C units.

Air Handling Units come in other variants; makeup air units (MAU), packaged units (PU), and rooftop units (RU). These are the larger units, whereas the smaller ones are referred to as terminal units. Some of the smaller ones are incredibly simple and may contain only an air filter, coil, and blower, and are called fan coil units or blower units. These are the kinds you could get for a private home or office, or a small building that doesn’t require a larger AHU. The larger AHUs work with both recirculated air and outdoor air. The MAUs work with recirculated air, while the RUs and PUs use outside air. The rest of this article will be focusing on rooftop units.

Rooftop units come in heating units, A/C units, and HVAC units that do both. Heating units come in three different types: gas heating, heat pumps, and electric heat. Most of these sound pretty straightforward. Gas heat uses mainly natural gas to heat the air pumped through it but can also be designed for propane. Electric heat uses heating coils that are, as stated, heated using electricity. The heat pump types take heat from the outside air and, through a series of pipes and valves, heat the inside air with it. The A/C units generally come with one type that only cools. There is another type called a year-round air conditioner (YAC) that provides both heating and cooling.

 

Rooftop Unit Maintenance and Repair

With all AHUs, upkeep is a necessity to keep your units working properly. Air filters need changing or cleaning every 3 to 4 weeks for optimal performance. Refrigerant levels need to be kept at a reasonable level if relevant. Any dirt, leaves, or debris need to be cleaned out of the outdoor units. Any damage should be noted and reported and then fixed, usually by calling the company who installed the AHU. Watch for leaks or unusual sounds, blocked air flow, or any changes in the performance of your unit. If you have any questions, call your AHU provider for information and repairs.
