Before you purchase a new Furnace, Air Conditioner, or Geothermal system, have an NCI certified contractor that can come to your home to test your existing system. There  is the real possibility that we can greatly improve the efficiency and comfort of your existing system without having to change out any of the equipment. There are several test methods available to you the consumer in the form of a Heatmaxx, Coolmax, or S.C.O.R.E. to help evaluate your current systems. Performance and help address concerns with any hot or cold rooms, high energy bills,  unneeded noise levels, or poor air circulation and air quality.                                    
Save Energy & Make Your Home More Comfortable                                                     Just because your heating and cooling system is operating doesn’t mean it’s working at peak efficiency.  Like your car; your heating and cooling equipment relies on many aspects to work together efficiently so that you get maximum comfort with a minimum energy cost.

National Comfort Institute trains heating and air conditioning contractors to test systems just like yours to determine existing efficiency and delivered comfortable air.   NCI also trains contractors how contractors can pinpoint troubles in your system and fix these problems.

Contractors that complete NCI’s Air Diagnostics and Balancing courses are certified to test your heating and cooling equipment and make the necessary recommendations and repairs to maximize the results in your home.

What is Air Balancing and Air Diagnostics?

ThermostatIf you are concerned about the efficiency or comfort provided by your heating and air conditioning system or if you are about to make a major purchase of a new heating or air conditioning system than you should learn about what air diagnostics and balancing can do for your home.

In its simplest form, air diagnostics and balancing is the process of testing and adjusting your air conditioning system to deliver the right amount of air to each room in your home. The actual Air Balancing process includes a number of related tests that determine the performance of your air conditioning and heating system.

House HeatAir balancing hoods are used to measure the amount of air at each grille. Manometers measure system pressures. Hygrometers measure system temperature and humidity. The
results of all these tests are compiled into a report to determine how well your system is functioning.

What Air Diagnostics & Balancing Can Do For Your System

It’s not uncommon to find a system 30% to 50% low on airflow. Air passes through the equipment and carries the heating or cooling inside. The effectiveness of the equipment is entirely dependent on the amount of airflow. When your certified technician measures the airflow he can "see" system performance.

Duct WorkWith this information, he can diagnose, repair and balance the duct system for maximum system performance. The end result is having rooms that are the same temperature, cleaner air, better humidity control and real energy savings.

Why This Service Is So Special

Air balancing is an ancient trade dating back to 1732 when a French Engineer named Henri Pitot created a method for measuring fluid pressure. Even though air balancing is critical to the performance of your air conditioning and heating system, less than 5000 individuals in the world are trained and certified in air balancing today. Make sure your contractor employs Certified Air Balancing Technicians.

Who can Do Air Diagnostics and Balancing?

Al with flowhoodYour heating and cooling system is a candidate for improvement. A contractor with the right tools and training can improve the performance of virtually any system. The more accessible your ductwork is, the easier it is to perform balancing and duct renovation work.

NCI Certified technicians are different than standard HVAC technicians. Most companies are in business to just fix or replace heating and cooling equipment. Your certified Air Balancing Technician considers the entire system and is qualified to test, diagnose, and repair your ducts as well as your equipment.

Don’t be fooled into thinking that replacing your furnace or air conditioner is the only way to lower your utility bills. Those big boxes that heat and cool are reliant upon the distribution system that delivers cold or warm air to each room. If a contractor doesn’t check them then they are only addressing part of the puzzle. Compare it to installing a brand-new race car engine on an old beat up sedan.

Al A heating contractor with diagnostic experience should always check the Static Pressure of your system whenever repairing or planning to replace your heating and/or cooling equipment. A familiar comparison is when you go to your doctor; someone always checks your blood pressure. Like blood pressure, Static Pressure is one of the key vital signs of your comfort system.

This test helps your contractor identify any significant blockage or leakage. With this initial testing along with an in-depth interview, your contractor can recommend the appropriate diagnostic tests followed by recommendations to correct existing issues and optimize your home’s comfort and energy efficiency.

Air balancing means measuring and adjusting the volume of airflow into each room. By doing this, every room in your home will be as comfortable as possible with the equipment you have on hand.
