Matching Condensing Units and Outdoor Coils
May 1, 2014
Imagine you have four old, worn-out tires on your car and you decide you only want to replace two of them. You can still drive your car, but you’ll soon be disappointed with the inconsistent handling and the poor mileage you get. The unmatched tires simply aren’t capable of the same level of performance. You could have these same kinds of problems with comfort and efficiency if the components of your central air conditioning or heat pump system are not properly matched.
It takes teamwork
Your central air conditioning or heat pump system is a split system. That means it consist of two parts: and indoor unit (coil) and outdoor (condensing) unit. These two parts are specifically designed to work together as a coordinated “team” to provide top performance and maximum efficiency and comfort. Plus, since both components are necessary for a working system, both parts of your existing system were originally installed at the same time — which means they both wear out at the same time. So if you install a new outdoor unit, be sure to include a new, equally efficient “matched” indoor unit.
When a bargain’s not a bargain
If you don’t replace your indoor unit, you won’t be getting what you paid for. In fact, your system could be up to 15% less efficient than stated — and you’ll be less comfortable, too. That’s why simply replacing just the outdoor unit isn’t a bargain in the long run.
Replacing the outdoor unit but leaving the old indoor unit may offer you the lowest price, but it won’t give you the best value. At best, when your air conditioning or heat pump components don’t match, you’ll be sacrificing comfort. The system may still “work,” but it won’t perform up to the promised energy efficiency. Over time, this will also cost you more money. At worst, when the components aren’t matched, it could create undue stress on your cooling system, resulting in unnecessary, premature failure.
Matched Systems Mean Maximum Satisfaction
When you consider the sacrifices and the added costs of repairing or replacing these unmatched units, installing a matched system the first time around makes good sense. You’ll get higher efficiencies, greater reliability and more comfort. And that’s a real bargain.
