Size
A synonym for the air conditioner’s cooling capacity, size is measured in British thermal units per hour (Btu/hr.) or in “tons.” One ton of cooling equals 12,000 Btu/hr.For sizing guidance, check our VENTECH(Vcare) type.
Efficiency
This describes how much cooling the unit delivers for each watt of electricity. Efficiency is expressed as the seasonal energy-efficiency rating, or SEER. The minimum SEER for a split system central air conditioner allowed today is 14, so look for units with SEER ratings of 15 or greater. The higher the SEER, the more you can lower your energy costs.
Maintenance
Central AC systems need regular maintenance for optimal performance. When you negotiate your installation, it's worth negotiating a service plan that combines regular inspections with discounts on repairs and a labor warranty into the overall price. Prices for such a service can vary widely.
Programmable thermostats
Setting your smart or programmable thermostat at the right temperature can reduce your cooling costs by about 10 percent. The right temperature varies on your comfort level, but start by setting it at 78° F and experiment until you find the sweet spot. You’ll save about 3 percent on your utility bill for every degree you raise the set temperature for your central air, according to the Department of Energy. And keep in mind that using a box or ceiling fan, which costs little to run, can make you feel 3° F to 4° F cooler.
