Older heating and cooling systems may run for years without major mechanical problems, but even so, they use so much energy that they become very expensive to operate. Equipment of fifteen years ago, like the automobiles of that era, is much less efficient than that of today.

In fact, most older furnaces are vastly less efficient than the models that Lennox now offers. For example, a typical gas furnace more than ten years old may operate at only half the efficiency of some new Lennox high-efficiency models.

Older heat pumps and air conditioners have the same drawback. Even units only five years old may operate at very low efficiencies, compared to today's Lennox models. In addition to costing you more to operate because of its low efficiency, every day you operate your old heating and cooling equipment, you run more of a risk of breakdown.

So whether you're faced with a breakdown or just know that your heating and cooling equipment is getting old, now is the time to replace it with a Lennox high-efficiency system.
