Buying an air conditioning system for your Dayton-area home is a big investment. You’ll want to make sure that the money you spend pays you back with the highest level of home comfort and the lowest monthly operating costs possible. To make sure you’re getting a cooling system that fits your needs and your home, schedule an expert consultation with an experienced contractor qualified to properly size, install and maintain a home comfort system.
In order for your A/C system to operate efficiently and keep you cool – without wasting energy and money – it must be the correct size for your home. Too much or too little cooling capacity and you’re headed for breakdowns and high utility bills. You could also end up with poor humidity control and a clammy feeling to the air in your house.
Most older homes have air conditioners that are too large. This is either because they were sized incorrectly initially or the home has become more airtight over time with added caulking, weatherstripping, energy-efficient windows or insulation. This being the case, it usually doesn’t work to go out and purchase the same-capacity equipment as you have now. A too-large unit is going to cost you more to buy, so there’s another reason to make sure you don’t go overboard on sizing.
A reputable contractor will determine the correct air conditioner by calculating the size according to Air Conditioning Contractors of America (ACCA) industry standards published in Manual J. Ductwork should be sized according to Manual D. These complex calculations take into account all the following factors to arrive at the proper sizing:
- Insulation R-value (thermal resistance)
- Shape, size and position of the home on the property
- Efficiency level of lighting and appliances that generate or radiate heat
- Window glass: amount, location, and type, plus any overhangs shading windows
- Air leakage
- Number and ages of household occupants
- Your comfort preferences
