Air Conditioner Buying Guide

Air Conditioner Size

  • Bigger isn't always better
  • An air conditioner that is too small can't keep up with your cooling requirements
  • An air conditioner that is too big will cycle on and off too frequently and struggle to dehumidify the air
  • An improperly sized air conditioner will not operate efficiently and will increase energy costs
  • Your air conditioner should be sized by a warrantied AC contractor

Air Conditioner Costs

  • Installation costs vary depending on your home
  • Select an air conditioner you can afford, but remember it is an investment
  • Air conditioner financing is available with approved credit

Air Conditioner Efficiency

  • Running your air conditioner in the summer will increase your energy bill
  • The more energy-efficient your air conditioner is the more you will save
  • Be sure to replace the outdoor condensing unit and the indoor evaporator for maximum efficiency
  • Higher SEER = higher efficiency

Air Conditioner SizingAir Conditioner Sizing

Getting the right size AC unit for your home is critical. When we say “size,” we’re referring to the BTU rating, not the actual physical size of the unit. There’s more to determining the right size than just totaling up the square footage of your house. That’s really just a starting point.

To properly size an AC system, the layout of your house, its age and airtightness, the number of windows, how much sunlight your home gets, and the existing duct system in your house all have to be taken into account. These factors are all part of what’s known in the industry as a “Manual-J” load calculation, and any competent HVAC contractor will consider these details when sizing an AC system.

Why You Need an AC Sized to Your Home

An AC system that’s too big or too small for your home causes all kinds of problems, from high electric bills to premature wear and inadequate cooling. You might be tempted to think a larger than necessary system will ensure your home stays cool on the hottest days. That would be wrong. Here’s why:

When you run an AC system, it doesn’t just lower the air temperature in your home. It also removes moisture in the air—essential during a hot and humid Wisconsin summer. For the AC system to remove moisture in the air, it has to run for a while. Trouble is, an oversized AC system never runs long enough to remove moisture in the air. Instead, it powers on in short, powerful bursts and shuts off a few minutes later. Besides causing uncomfortable temperature swings, these multiple start-ups and shut-downs also put more wear and tear on the equipment.

The flip side of an oversized AC system is one that’s undersized. In a worst case scenario, a too-small air conditioning system is never able to adequately cool your home. Because it’s running almost constantly to maintain the temperature you set on your thermostat, your energy bills skyrocket. An undersized system is also subject to premature wear from running so much.

Central Air Conditioner Replacement Costs

AC replacement costs can go up or down depending on the kind of air conditioner you buy, the quality of service, and the location of the air conditioner and more. Whether you just bought a new house or your old unit just decided to give up the ghost, that number can seem daunting. No matter how cheap or expensive it is to get your new air conditioner, that price is sure to beat sweating through a harsh summer. When you trust Southport to install or replace your air conditioner you get the best service available. All of our air conditioner contractors are prescreened and dedicated to delivering the highest service possible. All of work comes backed with Carrier's warranty and our 100% satisfaction guarantee.
