There’s no rule of thumb regarding HVAC systems, though many customers think there is. While one ton of air conditioning can cool anywhere from 300 to 800 square feet of a home or business, there are other factors to consider. Fortunately, we have 40 years of experience selling and installing furnaces and air conditioners to Maryland and Delaware neighbors. We can come to your home or business and inspect the property, allowing us to make an accurate recommendation. From there, we can help you choose the unit best for your budget and heating and cooling needs.
