What Are Your Best HVAC Options for Old Houses?

May 20, 2021

Old houses can be charming and beautiful. They can also be very difficult to cool and heat comfortably. There may not be adequate space to install a conventional central HVAC system without substantial and unsightly modifications. Furthermore, the cost of modifying older homes to accommodate ductwork may not be within your budget (or desire). Read on to learn about the best HVAC options for old houses and what you may expect for the installation process.

HVAC Options for Old Houses: Traditional Central Air

Traditional central air systems use a network of air ducts to convey the cooled and heated air to a home. Ducted central air conditioners and heat pumps have become the standard in American homes for indoor climate control.

However, the typical central air system may not be your best option for an old home, because installing a ductwork system may require substantial and expensive modifications to floors, walls, and ceilings.

HVAC Options for Old Houses: Ductless Mini-Split

Ductless mini-splits are great HVAC options for old houses. A ductless mini-split doesn't need bulky ductwork. Rather than air being cooled and heated for the entire home at a central air handler, a ductless mini-split cools and heats indoor air via small air handlers installed in the floor, wall, or ceiling in each room that needs air conditioning. A thin flexible tube connects each indoor air handler to a low-profile outdoor unit.

HVAC Options for Old Houses: High-Velocity Systems

Another indoor climate-control system to consider for best HVAC options for old houses is a high-velocity HVAC system. This type of cooling and heating system is a hybrid of a traditional, ducted central air system and a ductless mini-split system.

Rather than installing bulky air ducts, a high-velocity HVAC system uses an insulated two-inch air-supply tube to deliver cooled and heated air. The insulated tubing can be snaked through hidden spaces in walls, floors, and ceilings. The only visible component inside your old home would be small and unobtrusive disc-shaped registers.
