If you own a home or commercial building with a central HVAC system, you might be curious about a few things—and that’s a good thing! By arming yourself with HVAC knowledge, you have a better chance of steering clear of costly repair and replacement expenses. The following are some of the most common questions asked about central heaters and air conditioners and HVAC repair in Lexington, KY.
What does HVAC mean?
HVAC is short for “heating, ventilation and air conditioning.” These three functions are lumped together because they are very closely interrelated, and they all work together to bring indoor comfort your way. When installed and maintained properly, your HVAC system is able to function well and provide everything from good indoor air quality to comfortable temperatures on a daily basis.
How often should the air filter be replaced?
Air filters are extremely important components of HVAC systems. They need to be checked regularly and replaced when dirty to ensure healthy, clean air is coming through the ducts and into your living space. Keep in mind that the type, size and frequency at which it should be replaced varies from system to system—read your owner’s manual or contact an HVAC technician for this information. The average disposable air filter needs to be changed once a month, while high-efficiency filters can last up to three or four months depending on HVAC use and other factors. If you have a reusable filter, clean it thoroughly every month.
How does an HVAC system move air throughout a home?
There are many parts to HVAC systems. Some components are in place to power the system, others to protect delicate circuits, but they all work together to bring hot or cold air into your home every time the thermostat kicks on. So, how does the system move air throughout a building? A fan draws in indoor air through the return grills (or vents) that are placed throughout your home or business. This air travels through the ductwork running to your system’s air handler, then it’s returned into the conditioned space through air supply vents in your walls, floors or ceilings.
Are newer systems more efficient?
You might be wondering whether it makes sense to get a new HVAC system or just keep using your older working furnace or air conditioner. First, how old is your current system? If it’s more than 12 years old, consider replacing it with a new, higher efficiency system. This can help you save up to 50 percent on energy costs, as well as money on increasingly frequent HVAC repairs. What’s more is that high efficiency heating and air conditioning units offer better indoor comfort.
What is a SEER rating?
SEER stands for Seasonal Energy Efficiency Ratio, a government standard energy rating that reflects overall cooling system efficiency. It is a ratio of the cooling output divided by the power consumption and measures the performance of the system. Your system must have a SEER of at least 14 to qualify for the Energy Star program.
