Product Information


One of the industry’s most reliable air conditioners, the Trane XV18 TruComfort™ variable speed air conditioning unit offers up to 18.00 SEER2. It is available in sizes of 2, 3, 4, and 5-ton models. The XV18 features the Climatuff™ variable-speed inverter compressor, woven Spine Fin™ condenser coil, swept fan blade, and Trane Link connectivity. It’s been tested to stand up to the elements, while running as efficiently and cost effectively as possible, giving you peace of mind while lowering cooling costs in your home.

Looking for the same comfort level of a Trane XV20i, but on a budget? The functional components of the Trane XV18 variable speed air conditioner are identical to the XV20i. In order to offer a similar air conditioner at a lower price point, Trane removed the Weatherguard top and reduced the total coil surface area – just slightly lowering the rating to an 18 SEER2 efficiency

The XV18 still qualifies for the Air Conditioner tax credit, meaning that it can maintain high heat output even in northern climates such as Dayton, Ohio. Powered by an inverter-driven compressor, its variable capacity in tiny increments to perfectly match capacity to the current heating and cooling needs of your home. Longer runtime at a lower speed reduces wear and tear from starting and stopping. This enables the XV18 air conditioning system to deliver incredible humidity removal, super quiet operation, and unmatched comfort in both summer and winter.

Our estimated price of the Trane XV18 TruComfort™ air conditioner is $9,300 to $12,300 including installation. It’s important to note – it’s very difficult to find exact pricing online because it’s very difficult to estimate without seeing your house. Every home and installation comes with its own challenges. Our goal is to educate homeowners, equipping them to make the best decision for their home and budget. If your home needs a smaller 2 ton unit, and your current ductwork was engineered and installed correctly, you can expect an installed cost on the low end of this range. Obviously, a large 5 ton AC unit and/or difficult installation will put you at the higher end of the range. Get a free quote for your home here.

Compatible Matching Furnaces

The advanced technology in the XV18 only works with tight cooperation between the furnace, air conditioner, and thermostat. Therefore, the XV18 requires installation with matching indoor equipment, either a compatible Trane communicating air handler or gas furnace with evaporator coil. Our recommendation is either the Trane TAMX Hyperion Air Handler or the Trane XC95m Gas Furnace. For an exact, personalized recommendation, consult with our experts.
