5 Benefits of Replacing Your Furnace and AC Unit Together Some of the few benefits of replacing both your furnace and air conditioning units together are 1. It’s More Energy-Efficient One of the best advantages of replacing both your furnace and air conditioning unit is that it’s more energy efficient. Older residential and commercial HVAC systems take a lot more power to operate as compared to newer models. Newer furnaces and air conditioning units have many energy-saving components and features, this is why they can provide better performance at less power. If you replace one unit, you’ll be paying the same installation fee but still get an increased utility bill just because one system is not energy efficient. If both your furnace and AC units are more than 10 years old, we highly recommend replacing both HVAC systems so you can take proper advantage of their energy-saving features
