When it comes to cooling a home, the size of the air conditioning unit is an important factor. In general, for every 600 square feet, 1 ton of air conditioning is needed. This means that a 1,201 to 1,500 square foot home requires 2.5 tons, while a house from 1,501 to 1,800 needs 3 tons. For a 2000 square foot home, the best air conditioning capacity is 3.5 tons.
To cool a 3,000-square-foot home, you'll need a 5-ton unit. However, this rule may not apply in the Northern U. S., where extremely cold temperatures can reduce the capacity of mini-split heat pumps when heating is most needed. Other factors can also influence the size of the air conditioner you need. For example, if your home has high ceilings or glass windows in the back that let in more sunlight, you may need a smaller unit than what is recommended by the general rule.
If your air conditioner operator thinks the unit is too large or has had problems when the temperature in one room is lower than in the others, it makes sense to install a smaller unit. Without the window unit turned on, running an oversized central air with 5-ton ducts can result in a duty cycle that never exceeds ~50%, even when outdoor temperatures are around 90°F. This implies a load ratio of one ton per 1000 feet at outdoor temperatures of 10°F or more above the design temperature of 1%.If you're having trouble deciding on the right size air conditioner for your home, consider consulting with an expert. First Defense is a Houston company that specializes in solving real problems before spending money on replacing mechanical components and ducts. For example, if you have a 2200-square-foot single-story ranch facing south in New York with no shade and high ceilings in two larger rooms, you may need less than 20 BTU per square foot - something in terms of 10 to 15 BTUs per square foot. The same goes for a house in Dallas with 1765 square feet and 8 feet ceilings that doesn't have insulation on the outside walls but has good attic insulation.
Or if you have an 1800 square foot house in North Florida with high humidity and heat in summer. Finally, if your house is located in South Texas and has 2000 square feet of living space with 9-foot ceilings around the edges and measuring up to 10 and 16 feet in the cathedral-style living room, you may need less than 20 BTU per square foot - something in terms of 10 to 15 BTUs per square foot. In conclusion, it's important to consider all factors when determining how many tons of AC you need for your home. The general rule is that for every 600 square feet, 1 ton of air conditioning is needed. However, this may not always be true depending on your location and other factors such as high ceilings or glass windows that let in more sunlight. If you're having trouble deciding on the right size air conditioner for your home, consider consulting with an expert.
