An older HVAC system can cost your family money and create uncomfortable conditions in your home. This infographic, originally published by Davis Heating and Air Conditioning, reveals that modern HVAC (heating, ventilating, and air conditioning) systems use up to 50 percent less energy than the ones built in the 1970s. This is especially true when you pay attention to ratings, such as the SEER (seasonal energy efficiency rating) and EER (energy efficiency rating), which describe the efficiency of your air conditioner or furnace respectively.
Your air conditioning choices start with single-stage and multi-stage systems. Most single-stage systems cost less than their multi-stage counterparts, but they typically offer less energy efficiency. A multi-stage system sometimes costs more to purchase and install, but it will save you money over the long term thanks to decreased cooling bills. This is because a multi-stage air conditioner can run at both low and high power, so you won’t pay for extra energy consumption when you don’t need it. Regardless of the type of system you choose, look for a SEER of 14 or higher, which represents the modern energy-efficiency standard.
Furnaces and heat pumps are also critical components of your HVAC system. You’ll want an energy-efficient way to keep your home warm during the winter months. You can have a heating and cooling expert install a whole-house dehumidifier if you notice high humidity levels, and an air purification system might help you improve your home’s indoor air quality (IAQ) by removing allergens, pathogens, and other contaminants from the air you breathe. All of these components work together to keep your home efficient and comfortable.
