What's an HVAC Unit on the Roof?

A rooftop HVAC unit, often called a rooftop package unit, is a heating and cooling system that is built into the roof of your home or building. Everything is housed in one small cabinet, which connects directly to your existing ductwork. This format is different from standard split systems.

These systems are ideal for homes with little inside space, flat or low-slope roofs, or anyone who wants a heating and conditioning system that works well and is simple to keep up with.

Is a Rooftop Unit a Good Fit for Your Property?

Are you thinking about getting a rooftop system? It could be the best answer, if:

  • You want to make the most of the space inside
  • Your property has a flat roof or a roof that you can get to from the ground
  • You're putting in a new HVAC unit on the roof
  • You want a single system to handle both heating and cooling
  • For more comfort, you need zonal temperature control
  • You want an HVAC system that is quiet and easy to care for

At AES Heating and Air Conditioning, we look at your property and suggest the best rooftop system for your building depending on its layout, size, and energy consumption.

Advantages of Installing a Rooftop Unit

Installing an HVAC unit on the roof of a home or light commercial building offers several specific benefits:

  • Keep the inside of your house clear
    All components are installed outdoors, preserving interior space.
  • A single unit that can both heat and chill
    Rooftop systems provide all-in-one temperature control for year-round comfort.
  • Easy to maintain
    Technicians can access all system components easily from the roof.
  • Cleaner indoor appearance
    There is no need for bulky indoor equipment to clutter rooms or utility areas.
  • Less noise when running
    Since the unit is outside, most operational noise stays out of earshot.
  • Great for homeowners and small businesses
    This unit is particularly suitable for properties that have flat roofs and have limited indoor mechanical space.

We proudly install systems from top companies like Carrier, Trane, Goodman, and Rheem to make sure they last and work well. These systems use current, energy-saving technologies to improve efficiency.

What Our Rooftop Unit Installation Service Includes

We handle all the little things:

  • Free advice and suggestions on the best system from an expert

  • Optional zone system setup for more comfort

Frequently Asked Questions About Rooftop Unit Installation

What’s the benefit of using a rooftop unit instead of a split system?

Rooftop units save indoor space, reduce noise, and simplify maintenance because everything is in one outdoor cabinet.

Do rooftop units last as long as traditional systems?

Yes — with proper maintenance, most rooftop systems last 15–20 years, just like split systems.

Do I need a crane to install a rooftop unit?

Possibly. For most installations, a crane is needed to lift the unit onto the roof. We handle scheduling, permits, and safety protocols if required.

Can I install a rooftop unit on a pitched roof?

Not typically. These systems are best suited for flat or gently sloped roofs. We’ll inspect your structure and offer alternatives if needed.

Are rooftop systems more expensive to install?

They can involve more logistics (like cranes and permits), but they also save on indoor remodeling and long-term maintenance.

Do you offer rooftop unit repair or maintenance?

Yes — we offer repairs, inspections, and maintenance for existing rooftop units, even if we didn’t install them.
