According to the government's Energy Star website, this is the base capacity needed for a 1,200 to 1,400 square feet house. Each indoor unit can then be programmed to maintain a different temperature, thus creating separate cooling zones. Some sit in the home and are mounted on the walls and some can be mounted in the ceiling. The air handler uses 2 conductors plus ground (no neutral) for each circuit and I have not seen or been able to find 2-conductor copper plus ground in 1 AWG or larger. Many of the same rules of thumb that apply for larger commercial spaces also apply for residential ones. One of the best rules of thumb for residential fresh air requirements is 100 cfm for every 600 to 900 sq.ft. Tonnage ratings are typically expressed in increments of .5 tons, so residential air conditioners are usually rated as 1.5, 2, 2.5, 3, 3.5, 4, 4.5 or 5 ton units. function rH(m){if(isNaN(parseInt(m.data.useHeight,10))){return}
But what size do you need? A small hole of less than 3 inches in diameter is made in the wall to accommodate electrical wiring and copper tubing that connects the outdoor unit to the indoor unit. The return vent is normally bigger than your supply vents since it’s exactly how the air handler sucks the air right into the HVAC system. The Manual J calculation is the most precise measurement available because it considers factors like: that will provide you with your Manual J calculation — just ask. The air handler cabinet houses indoor components of your HVAC system and can fit additional devices that improve air quality and ventilation. What this means is that if your home needs 6-tons of cooling power for instance, then you’d need two, 3-ton units installed (instead of a single 6-ton unit). 1 ton of cooling is equal to 12,000 BTUs. A gas or electric furnace is a more effective way to heat the location.How do I select an air handler?If you live in a warm climate, where the combination of an air handler and air conditioner or heat pump provides sufficient heating and cooling, it's time to look at air handlers. Do the math. Then multiply that by hours of operation annually and finally by cost of Kwh for that particular unit. Refer to the air handler rating plate for maximum overcurrent protection, minimum circuit ampacity, as well as operating voltage. It should be noted that there is a distinct difference between BTU and BTUh.
In the worst case, the mismatched system may not work at all. As a result, your outdoor unit doesn’t have to work as hard. Well I’m not going to lie and tell you the answer is easy like so many other sites will. This will let you know how many tons per square feet your air condenser needs to be. in. How to check the temperature of the air around your AC unit: With the AC unit running, measure the intake air temperature at the midpoint of the intake (a few inches from the AC coil). var ifr=d.createElement('iframe');var itr=0;var inv;
Take the BTUs divided by the SEER and then divide that by 1000 to see how many Kwh consumed each hour. You can also get a rough estimate by looking at the square footage of your house. An air handler is a common part of a split-system AC or heat pump. protection are to be supplied by the installer. The final question is how much fresh air is needed? A ton, as used in the HVAC field, is a term that describes how much heat the AC unit can remove from a home in one hour. How long do you plan staying in your current home? If you have an electric heat pump, you probably have only an air handler. The excess air needs somewhere to go, which area is the return vent.

Anything over 5-tons is generally considered a light commercial HVAC unit (not available for residential projects) and if your house requires an AC unit of this size, then you’ll need to install multiple AC units in tandem.
