At Reed Heating and Air, here in Alabama, we want to make sure you have a clear understanding of heating and air conditioning terminology. Here are some important phrases, words, and acronyms you may need to know.
First, let’s talk about the heat exchanger. This component of your heating system transfers heat to the air that circulates throughout your home. It is the largest part of your furnace, and over time, it can develop cracks. This can cause incomplete fuel combustion and release dangerous carbon monoxide into the air in your home. That’s why it’s important to have regular maintenance and inspections from a trusted technician.
- You may have heard the acronym HVAC before. It stands for Heating, Ventilation, and Air Conditioning. This term refers to a system that includes a furnace, air conditioner, and some method of circulating warm and cool air throughout your home. The industry as a whole is referred to as H-VAC, which is good to know when speaking with professionals in the field.
- MERV, or Minimum Efficiency Reporting Value, is a rating for air filters. Air filters have tiny holes that allow air to pass through while trapping small particles in the air. The higher the MERV rating, the more efficient the filter is at trapping small particles like mold, viruses, dust, and dander. This is important to keep in mind for those who suffer from allergies or respiratory issues.
- Micron – When it comes to measuring small particles, we use the unit of measurement known as a micron. One micron is one-millionth of a meter or 1/25,000th of an inch. Tiny particles like mold, viruses, dust, and dander can circulate with your home’s air, and an air filter can trap these tiny one-micron particles. If these particles are allowed to circulate, they can have harmful effects on your health.
- It’s also important to know about NATE Certification. NATE stands for North American Technician Excellence, and it is an industry training and testing organization that certifies that service technicians have passed rigorous testing and are certified experts in the HVAC industry. Homeowners can have peace of mind knowing that NATE-certified technicians are installing and servicing their heating and cooling equipment.
- Refrigerants are chemical compounds that produce a cooling effect while expanding. R22 refrigerant, also known as Freon, is still found in many home air conditioners but has been banned from new systems due to its harmful effects on the ozone layer. R410-A refrigerant is the most common replacement for R22. It does not contain the ozone-depleting qualities of R22 and is a more environmentally friendly option.
- A ton is a unit of measurement for cooling capacity. One ton of air conditioning can remove 12,000 BTUs of heat in one hour. Home air conditioners or heat pumps typically come in the 2-ton to 5-ton range.
- Finally, let’s talk about some advanced technologies in heating and air conditioning. A smart thermostat is a device that can observe your daily routine and adjust its settings accordingly. It can even detect when you’re away from home for extended periods and adjust your home’s temperature accordingly. With online connectivity, you can even control your thermostat remotely, so your home is always the perfect temperature when you arrive.
- Another advanced technology is zoned HVAC. This system allows you to direct air to specific areas of your home using dampers in the ductwork. This customization can help you save energy and money by only heating or cooling the areas of your home that need it.
