The HVAC sizing estimator above is a great way to determine the HVAC size that you may need to keep your home more comfortable. What size HVAC do I need for a 2200 square foot home that has average insulation condition? Header What size HVAC unit do I need for an 1800 square foot home with average insulation condition? What size HVAC unit do I need for a 1500 square foot home with average insulation condition? We’re considering that the system will include central air conditioning and a furnace. Check Your Results: Sample HVAC Sizing Tablesįor the examples below, the zones are noted, the insulation condition is considered “average,” and the sun exposure is “very sunny” for the hot climate, “sunny” for the warm climate, and “heavily shaded” for the cold climate. Once everything is filled in on the calculator, it will crunch the numbers and give you the results – the size of both the air conditioner or heat pump and furnace BTUs if included in your HVAC system. Below 2,400 like Oregon and Michigan would be called a cloudy area. Between 2,400 and 3,000, like North Carolina and Maryland, is considered average. If the number is above 3,000, like Arizona and Colorado, you live in a sunny spot. How sunny is it where you live? This is a general question – or if you want to get specific, you can find the number of sunshine hours that is average for your state. Homes in “poor” condition tend to be drafty. The windows and doors are not sealed well and some rooms are either cooler or hotter than others, depending on the season. Poor Condition: Older homes that have not been updated would be considered to have “poor” insulation conditions. Some homes that were built pre-1990 with upgraded windows, doors, and/or insulation can also be considered to be in “average” insulation condition. Good Condition: To determine that your home’s insulation is in “good” condition you will need the following: a house wrap (Tyvek), ample insulation in your attic, and energy efficient windows and doors.Īverage Condition: If your home was built between 19 and has not been updated to make it “energy efficient,” you would consider the insulation of your home to be in “average” condition. Choose the one that works best for your house. You have three options to decide from when determining the insulation condition of your home. What about the basement? If you intend to heat it, include it in your square foot total. Simply determine the area of each room in your home and total the room sizes up to get the total square footage in your home. If that number is still unavailable, you can figure out the square footage yourself by using the area formula (length x width). If you don’t know the square footage, you can possibly find the square footage number on your home’s blueprints that would be located on closing documents. But it would be a big deal if the furnace were too small, so going up a Zone if you’re close to the edge will guarantee you get enough furnace to keep your home comfortable.įill in the square footage of your home, if you happen to know it. Why? Because you might end up with an AC that is slightly too large, and that’s not a big deal. If you happen to be close to two different zones, you should use the zone that is the higher number, which is the cooler zone. Looking on the map, locate the zone where you live. Four Steps to Understanding the HVAC Size Calculator But again, it depends on all the factors considered in the calculator. However, to get exact HVAC sizing for your home, fill out all the details in the calculator.Īccording to the calculator, a 2.5 to 3 ton AC will do the job along with an 80,000 BTU furnace. That’s in Zone 4 – a zone with average temperatures. The HVAC size is 2.5 to 3 tons for the AC and 70,000 BTU for the furnace.
