Improve Building Efficiency With Modern RTU Systems

Reduce energy costs. Improve your indoor comfort with expert rooftop HVAC installation in Chicago. Older units often struggle with:
  • Outdated internal components
  • Inefficient operations

They work twice as hard to produce less heat or cool air.

Rooftop units use advanced motors and high-SEER2 technology to save on energy costs. Because they adapt to temperature shifts in real time, these systems reduce unnecessary cycling that drives up your monthly utilities.

Enhance your property’s sustainability. Ensure long-term reliability. These are just two of the many advantages you’ll see when you install a precision-engineered RTU system.

Repair & Installation

Freqently Asked Questions

1
What is a rooftop package unit?

An RTU is a complete heating and cooling system. All components are kept in a single weather-protected cabinet to save space.

We install these systems directly on the roof to:

  • Save interior space
  • Simplify your property’s comfort
2
How long does rooftop HVAC installation take?
Standard residential rooftop HVAC installation projects typically take one to two days. New systems that need extensive ductwork or structural reinforcement of the roof often take longer. We coordinate permits and crane services beforehand to reduce downtime for your home or business.
3
How much does rooftop package unit installation cost?

Prices for RTU installation depend on several factors:

  • The unit’s tonnage
  • The system’s SEER2 rating
  • The complexity of the roof crane list

We perform a site evaluation to give you an accurate quote.

4
Are rooftop HVAC systems energy efficient?

Yes. These units use advanced compressors and fan technology to meet or exceed federal energy standards. They consolidate heating and cooling into a single cabinet to reduce energy loss.

A system with a high-SEER2 rating significantly lowers monthly utility overhead.

5
Can rooftop HVAC units be installed on homes?

Absolutely. These systems are ideal for flat roofs or residences with limited yard space.

We specialize in rooftop unit installation for residential properties. Call us to see how we can help transform your indoor comfort.

6
How long do rooftop HVAC systems last?

15-20 years if the unit receives consistent professional maintenance. Rooftop systems receive constant exposure to the elements.

That’s why we recommend bi-annual inspections to maximize the operational efficiency and lifespan of your investment.

7
Do you service commercial rooftop HVAC systems?
Yes. We provide maintenance services as well as repair and replacement. Our technicians handle systems of all sizes and ensure your business stays compliant with local building codes.
8
What are the signs I need RTU replacement?

Consider a new RTU installation if you notice any of the following:

  • A sudden spike in energy costs. This is often a sign of a failed compressor or motor.
  • You frequently repair your unit (more than twice a year).
  • Grinding or banging sounds. These are signs that the internal components are failing.
  • Some rooms are freezing while others are hot. Your unit may no longer be able to handle the load.
