When picking central air conditioning – size matters. Underestimate your cooling needs, and you could be sweating. Buy more power than you need and your living space may become cold and clammy. We take the time to calculate your cooling needs by using such recognized methods as the Air Conditioning Contractors of America (ACCA) Manual J. We also use duct-sizing method from the ACCA Manual D. We check to make sure that all duct sections are properly sized and that there are enough supply registers to deliver sufficient air to the right spots. (Not only is the proper size ductwork essential for meeting each room’s cooling needs but also because undersized ductwork can make for noisy operation.) Leaky or uninsulated ducts can reduce system efficiency considerably. All joints and seams must be sealed–and not with duct tape that can dry and fall off.
Size, Design and Efficiency Also Matter:
Size is a synonym for the air conditioner’s cooling capacity, measured in British thermal units per hour (Btu/hr.) or in “tons.” One ton of cooling equals 12,000 Btu/hr. In a “split system,” the typical design, refrigerant circulates between an indoor fan-and-coil and a matching outdoor condenser with compressor. The refrigerant cools the air, dehumidifying it in the process; a blower circulates air through ducts throughout the house. Efficiency 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 is 13.)
We can help assist you pick the model that’s right for you and your home. We’ll calculate the annual estimated operating cost of each model you’re considering. We’ll plug in information on each unit’s Btu and electrical consumption, local utility rates, and characteristics of your home into our software to easily calculate very accurate estimates. Once the unit is installed, we offer cost-effective preventive maintenance (according to the manufacturer’s recommendations) to safeguard and extend the life of the equipment.
