A copper tube aluminum fin coil, high and low pressure switches, and liquid line filter drier are additional components of this series.

As a commercial unit, the 38TDB Infinity has very few consumer reviews across the web. However, the Carrier Infinity air conditioning series has a strong presence on review sites and forums. Several review sites, including webhvac.com and hvacreview.net, recommend these systems for homeowners in warmer climates because of the unit's high efficiency and durability.
Homeowners and contractors on gardenweb.com also are pleased with Carrier’s top-of-the-line Infinity units. Although several homeowners mention the installation took more than a day and the unit’s high price point, other consumers report a noticeable decrease in their utility bill with the new unit. With minimal troubleshooting issues reported across the web, professionals also note very little issues with these systems when properly installed.
The Infinity 18 is available in different models which vary in efficiency and capacity.
