Expert guides on choosing the right air conditioner size based on square footage, BTU requirements, tonnage, and climate conditions.
If you are trying to figure out what size AC you need in South Dakota, most homes land somewhere between 2 tons and 5 tons. But South Dakota is one of those states where the summer cooling problem often looks smaller on paper than it feels inside the hardest rooms. A house on an open…
If you are trying to figure out what size AC you need in West Virginia, most homes land somewhere between 2 tons and 5 tons. But West Virginia is one of those states where house layout and local topography can change the answer more than homeowners expect. A split-level home built into a hillside does…
If you are trying to figure out what size AC you need in Vermont, most homes land somewhere between 1.5 tons and 4 tons. But Vermont is one of those states where the question is often less about extreme statewide cooling demand and more about which rooms actually become uncomfortable in summer. A shaded farmhouse…
If you are trying to figure out what size AC you need in New Hampshire, most homes land somewhere between 1.5 tons and 5 tons. But New Hampshire is one of those states where the answer depends less on “how hot the state feels overall” and more on how the house behaves in summer. A…
If you are replacing your air conditioner, it is normal to focus on the new unit first. But one of the smartest questions you can ask is: Should you replace ductwork when replacing AC? The honest answer is: sometimes yes, sometimes no. You do not automatically need brand-new ductwork just because you are installing a…
If you are asking whether one AC unit for a two-story house can really work, the honest answer is: sometimes yes, but not always well. That is because a two-story house is rarely one simple cooling problem. The upper floor usually carries more summer load than the lower floor, and that creates a built-in imbalance….
If you are asking 5 ton AC for how many square feet, you are looking at one of the largest common residential system sizes. A 5 ton AC provides about 60,000 BTU of cooling capacity, which means the house either needs a lot of cooling or the installer believes it does. The problem is that…
If you are asking 3.5 ton AC for how many square feet, you are looking at a system with about 42,000 BTU of cooling capacity. That places it in the upper-middle part of typical residential sizing, where a half-ton difference can noticeably change how the house feels. But square footage alone never gives the whole…
If you are asking 3 ton AC for how many square feet, the rough planning range is usually around 1,600 to 2,200 square feet. But that is not the real answer by itself. A 3 ton AC can be perfect for one house and wrong for another house with the exact same square footage. Climate,…
If you are trying to figure out what size AC you need in Maine, most homes land somewhere between 1.5 tons and 5 tons. But Maine is one of those states where homeowners often underestimate cooling demand because the market is better known for heating than cooling. That does not mean cooling is irrelevant. In…
