Each ton corresponds to 12,000 British thermal units (BTUs).
Be careful when calculating this, because bigger isn't necessarily better.
If your unit is too large for the space of your home, it will switch on and off repeatedly, wasting energy and costing you money.
If you’re lucky, your home has current ducts set up and central air conditioning is a possibility.
An air conditioner’s power is measured by BTUs, which are defined as the amount of energy needed to cool or heat up one pound of water by a Fahrenheit.
All in all, it measures and ultimately determines what size your air conditioner must be to cool the entire home.
You can see all costs at Types of Air Conditioners.
Another factor that will affect the cost of central air installation is whether or not you need to install ducks and vents.
Finally, besides the unit itself, the cost of materials, supplies and equipment allowance will run you another to 0.If your home is 1,600 square feet, a 2.5 ton air conditioner will cool it well and cost between ,000 and ,000.There are platinum models that could potentially cost ,000, but these are rarely necessary.The best EER rating you can have is 80db/67wb inside.The seasonal energy-efficiency ratio (SEER) looks at how efficient your system is through all four seasons.
