Home Humidity Control | Why Its Important for Comfort & Health - Humidity is important to our home and health and it is important to maintain the correct humidity in our homes and workplaces for our health. What is humidity? Humidity is simply little water droplets in the air. Cold air is nearly saturated with these little water droplets because the contents of cold air allow the air to hold more water droplets or humidity. As air is heated it expands and holds less humidity. (more…)
HVAC Green Technology | Heating and Cooling - First of all, we need to define Green Technology before we compare it to HVAC and discuss how the HVAC industry is working to make the equipment and designs used in Green Technology, friendly to the environment. Green Technology uses evolving technology in utilizing methods and materials to develop techniques that are more friendly to the environment than previous methods and materials.(more…)
What is NATE? HVAC Education NATE Certification - NATE stands for North American Technician Excellence and NATE is a certification group that oversees the training, testing, and certification of HVACR technicians throughout North American. NATE is highly respected throughout the HVACR industry and an HVAC technician who achieves NATE certification is considered very knowledgeable and skilled in the HVAC trade or HVAC certification specialty. It is a step up in heating and cooling education for HVAC Techs. (more…)
SEER Definition: The Seasonal Energy Efficiency Ratio is a measure of the cooling efficiency of your air conditioner or heat pump. The higher the SEER number the better the system is at converting electricity into cooling your home. Simply put, manufacturers use it to differentiate between less efficient equipment to the more efficient equipment they sell.
Equipment is tested in a third-party laboratory and the results are certified by ARI. Furthermore, the result of the testing can be looked up in the ARI database for each of equipment if you have the model number. It should be noted that ARI uses strict testing parameters in testing HVAC equipment. Additionally, these standards are issued by ANSI or other respected organizations that issue standardization rules throughout the industry. (more…)
Variable Speed GE ECM Motors - When you look at buying a new HVAC system it will surely arise when the HVAC salesman or HVAC contractor who comes to give you an estimate will show an HVAC system that has a variable speed motor or the GE ECM (Electronically Commutated Motor) installed in it. These are systems that have a higher efficiency rating than the HVAC equipment that has the typical electric blower or condenser fan motor. (more…)
HVAC Professional Organizations | Heating and Cooling - Many people ask the question(s) what is ASHRAE? Or what is ARI? Or what is SMACNA? These organizations are all involved in HVAC and set the standards for the HVAC industry that most professional HVAC manufacturers and companies follow.
Engineers use standards by these and other professional organizations to write specifications for construction projects and government agencies use the standards produced by these organizations (and others) to define requirements for government construction projects. (more…)
HVAC Tip - Some people refer to refrigerant as Freon. So when something is wrong with their HVAC system they say, “I have a Freon leak”. Freon is a name trademarked by Dupont for R-22. R-22 is being phased out because it contains chlorine. While Freon will soon be a thing of the past, the name Freon has found its way in our lexicon as a reference to refrigerant, any type of refrigerant.
