Do you know what an HVAC contractor should test for when installing new high efficiency equipment? Before investing in a new high efficiency heating and cooling system, you need to make sure you select a contractor that installs equipment based on facts, testing, and science. Unfortunately, many HVAC contractors offer advice on new high efficiency heating and cooling systems based on opinions and guesses. When selecting an HVAC contractor, make sure the contractor meets the minimum criteria listed below:

  • Computerized “Manuel J” Load Calculation – This is a room by room scientific test that will determine the right size equipment for your home.
  • Room by Room Airflow Calculation – This is a scientific measurement of the amount of air coming out of the air vent in each room. This will ensure your new system heats and cools your home evenly.
  • Air Duct Leakage Calculation – The typical duct system in a home leaks 25-40%. The air duct leakage test identifies where the leaks are located so repairs can be made.
  • Air Flow Leakage Reduction Guarantee – Get a written guarantee that the duct system will leak less than 10%, or that they will guarantee 75% less air leakage once the new system is installed.
  • Infiltrometer Blower Door Test – This is a scientific test that measures the level of air leakage in the entire home. Understanding this will help solve high utility bills, unhealthy indoor air, musty odors, excessive dust, humidity issues and hot and cold spots throughout the home.
