We have designed hundreds of HVAC systems and know what it takes to meet Chicago’s ever-changing weather demands.

An Accurately Designed HVAC System Will:

Save Energy & Money

The heating and cooling equipment will NOT perform better if it is BIGGER than it needs to be. Research has shown that when the HVAC is too large for the home, it can cause structural damage due to excess humidity. And let’s not forget the bigger price tag for the unit itself and the subsequent operating costs for the larger fan and compressor. An accurate and efficient  system will run steadily without stopping and starting for better comfort and lower utility costs.

Deliver Year-Round Comfort & Better Structural Durability

Relative humidity levels in residential houses should be around 50% in the cooling season (summer) for the Chicago area; if you have higher levels, it could indicate a problem. This often happens when an AC system is too large.

During the heating season (winter), comfort is impacted by oversized mechanical systems as well, especially with heat pumps. A heat pump has to move more air around in order for it to maintain even temperatures. If it is too large, it will have to move even more air, creating chilly drafts. Priority Energy’s HVAC design services will make sure you are comfortably cool, cozy and warm when you need it.

Did you know that too much or too little indoor humidity is not only uncomfortable, but it can also be damaging to your home? We will develop a balanced system that will prevent moisture problems and maintain relative humidity levels of 40 to 60 percent for optimal comfort and structural durability.

Provide Healthier Indoor Air

Strange odors, mold, mildew and dust mites have been traced back to HVAC systems that are not effectively dehumidifying a home or building. Allergy and asthma symptoms have also been linked to exposure to these indoor contaminates. Priority Energy’s accurate load calculations (Manual J & D) and ductwork design (Manual S) will help ensure adequate airflow, ventilation and humidity control is reaching all the rooms in your home or building for a safe and comfortable environment.

HVAC Commercial Design, Test & Balance

Priority Energy, HVAC design & test commerical, IL

The mechanical system that heats, cools and ventilates your business is typically one of the most expensive line items business owners face, be it new construction, replacing an old system or simply the operating costs for the heating and cooling of your space.

If only expensive equated to better!  For many business owners, it seems to be a never-ending battle to keep your business (and, more importantly, your customer) comfortable. Is this a battle you may be losing? Do any of the following problems sound familiar?

  • Thank you again and you will be the first person I call if I need additional part or service from your company.
  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • Thanks for a super intelligent and deep seminar expertly handled by a staff which was a pleasure to be around. Lunch was superbly and subtly handled.

  • Anytime I can be a reference for all the great work on my (new) house, please let me know.  Priority Energy is outstanding at what they do!

    Executive at Medline Industries, IL
  • I have a two story home built in the mid seventies. Lots of temperature fluctuation between the floors. The Aeroseal process dramatically increased the air flow to the second floor. Good experience. The company was very informative, answered a lot of questions.
