National Comfort Institute (NCI) Just because your heating and cooling system is operating doesn’t mean it’s working at peak efficiency. Like your body, your home heating and cooling equipment relies on many things to work together efficiently so you get maximum comfort with a minimum energy cost. Typical installed equipment only operates at 55% to 70% of rated capacity. Think of the airflow through your house like blood through your veins. Proper blood flow, or air flow, will cause optimal environments. Most contractors don’t even know how to diagnose all the parts of your HVAC system, let alone measure and show you actual numbers representing the blood pressure of your HVAC system. Your heating and cooling system is a candidate for improvement. An HVAC professional with the right tools and training can improve the performance of virtually any system. At Hopkins Air, we provide our technicians with such tools and training. Nearly all of our in field technicians are NCI Certified. What does that mean for you, the consumer? NCI Certified Professionals are different than standard HVAC technicians. Most companies are in business to just fix or replace heating and cooling equipment. Our Hopkins Air Conditioning technicians consider the entire system and are qualified to test, diagnose, and repair your ducts as well as your equipment. Don't be fooled into thinking that replacing your air conditioning unit is the only way to lower utility bills. The units that heat and cool your home are reliant upon the distribution system to deliver cold or warm air to each room. If a contractor doesn't check that distribution system, or the ductwork, then they are only addressing part of the puzzle. Compare it to installing a brand-new race car engine into an old sedan.
