Replacing your air conditioning system
To obtain optimum energy saving and comfort levels, the indoor and outdoor units should be replaced at the same time. Far too often homeowners only replace the outdoor unit and neglect replacing the indoor unit. As a result, the new system doesn't always live up to their expectations. They don't get the desired results because the indoor and outdoor units are designed to work as a team. They are matched in both capacity and efficiency when first installed and should be matched again when replaced.
Replacing an old outdoor unit with a new high efficiency model without replacing the indoor unit with an equally efficient model will simply not produce the desired performance. Replacing both units will increase the initial cost of replacing the system. However, Home Comfort Institute experts say the increase in energy savings, comfort level and overall reliability is well worth the investment.
This must be one of the most often asked question, when faced with so many brands. It is impossible to choose a brand on a scale from one to ten. There are however, some factors and tips you could consider:
Where is the money invested?
Many companies focus a lot of their time, research and money into reaching the targeted audience. Marketing is a powerful tool, but who really benefits from repetitive visual/audio exposure? You win, when your manufacturer invests their time and money in production quality.
What are unique features?
Although it is comforting when a manufacturer knows who it's targeted audience is, and they can design some features directly to your interest; isn't it more important that special features have actual benefits for you and not just product reputation. Make sure special features are really needed or important to you.
Who should I listen to?
It is always most wise to consult a third party non beneficial to your purchase. How about your neighbour or family member? Consumer Reports are dedicated to be buyer beware and actually test competitive brands. You can see their ratings at http://www.consumerreports.org
