What type of AC replacement is right for you?

A common question is whether or not the ductwork needs to be replaced. If your home already has ductwork, then you’ll likely want to go with another central AC replacement option. Especially if your existing ductwork is still in good shape.

Central air conditioning is what most people think of when researching AC replacement and installation in Houston. A central air system features an outdoor condenser unit, an indoor coil and furnace, and interior ductwork, which is usually hidden in the attic. Central air conditioning systems – especially our Lennox XC25 with variable speed – are great for lowering humidity and improving air quality. They have other benefits, too:

    • Keep the whole house cool
  • Improve the value of your home
  • Are virtually invisible (Just a few vents are all you see.)
  • Offer easy installation if you have existing ductwork
  • Eliminate the need for an open window – a big safety risk!

Ductless Systems

However, some homes don’t have ductwork because the home has had window units. In that case, a ductless system might be the better choice.

The most common form of ductless AC system is the mini-split-system. These units feature an outdoor condenser unit and an indoor air-handling unit connected by a conduit. These are great AC replacement options for older buildings with thick walls, home additions, small apartments or any place where putting in ductwork isn’t an option.

A ductless mini-split-system offers a wide range of benefits:

Lets you cool one room or zone, or up to five at a time

Small size

Mounts to wall

Offers remote-control functionality

Does not require ductwork

Because quality and efficiency matter, we proudly carry the Daikin brand, which offers an efficiency rating of up to 25 SEER.
