There are very few places on earth where people are comfortable living without heating and air conditioning, and the United States is not usually considered one of them. Weather you live in a state with hot and sticky summers, or freezing cold, snowy winters, you are going to want an efficient HVAC unit. But how much will it cost?

The price of residential HVAC depends on the size of the house, the quality and brand of the unit, the region in which it’s being built, and the type of fuel it will use. Initial installation cost is one thing, but it’s important to consider the cost of fuel in the long run as well. High-efficiency systems can be more expensive to install, but will pay off over time. Maintenance costs are also something to consider. A complete overhaul or entirely new system with new ducts will cost more.

Installing an air conditioning system in your home can range from $3,000 to $6,000 depending on the situation of the home and the duct work. For a 1,900 square foot home, an new unit may cost around $3,500-$4,500, not counting the cost of installation.

The region in which you live will play a big factor in your final cost. If you live in the Midwest, the South, or the country, you will pay less than if you live in the Northeast or West Coast regions. In Raleigh, North Carolina, for example, a reasonable estimate would be somewhere around $3,800-$4,200 for changing a 2-ton system. This price would be a bargain if you lived in Maryland or New York, where prices are on average closer to $10,000 or more. Estimates can range closer to $20,000 for a complete HVAC overhaul on a large house. Every project is different, so it is difficult to say exactly what the cost will be. As a nationwide average, homeowners should expect to pay somewhere around $5,000 on new heating, cooling, and ventilation systems, then factor in the labor.

The cost of your project will also depend greatly on which contractor you choose. Estimates for the same project can differ by thousands of dollars, so it is definitely to your advantage to obtain several before choosing between HVAC contractors. When reviewing an estimate, make sure you understand exactly what it includes and what it does not include. It always helps to get as much information as possible from your perspective contractors.
