GM: Tell us the history behind Design Aire and your role at the company
Seth: Design Aire was started in 1904 when my great grandfather, Frank Fischer, began installing steam heating systems in South St. Louis. I started working at the company delivering duct systems for new construction during my high school and college summers. Currently, I am in charge of sales and marketing for our residential and replacement division.
GM: What regular maintenance do heating and air conditioning systems need?
Seth: The main task performed for furnace maintenance is the inspection of the heat exchanger. If a heat exchanger is cracked, carbon monoxide or other harmful flue gases can enter your conditioned air. A licensed service technician should check your furnace every fall to make sure that your heat exchanger is operating safely. The technician will also clean your furnace and make sure it is operating efficiently.
The two primary functions of air conditioner maintenance are to clean the AC/condenser coil and check the refrigerant charge. Both a dirty coil and low refrigerant levels will negatively impact the efficiency of the system which will result in elevated electric bills.
GM: How often should an air filter be replaced?
Seth: The most important HVAC maintenance that almost every homeowner can perform is replacing the furnace filter. Most inexpensive filters should be changed every 30 days. Upgraded, pleated filters are designed to last 3-6 months.
GM: How important is air quality and what factors need to be considered?
Seth: The most important indoor air quality improvement that any St. Louis homeowner should consider is a whole-house humidifier. Both the reduced outdoor relative humidity and the process of heating your indoor air combine to lower the humidity levels in some home’s to uncomfortable levels. To protect your home’s woodwork, your family’s sinuses, and to eliminate those annoying electric shocks, I recommend every St. Louis home have a whole-house humidifier.
GM: What is two-stage heating?
Seth: Two-stage heating and air conditioning is a relatively recent advancement in the HVAC industry. The idea is that most systems are designed for the extreme temperature days. You want your home to be cool when it is 95 degrees outside, and warm when it is 5 degrees. Your home’s heating and air conditioning capacity should be sized to handle these days, but the vast majority of our temperatures are not that extreme. Often you don’t need the full capacity of your system to adequately condition your home. Two-stage furnaces and air conditioners are capable of operating primarily in a 50-70% capacity while still offering 100% capacity when necessary. Two-stage systems are both more efficient and more comfortable.
GM: Any current trends in the HVAC industry?
Seth: The main trend in the HVAC industry parallels a larger trend: home automation. Wi-Fi thermostats are the most requested system upgrade of the year, and they are just the beginning of automation in home air conditioning.
