HVAC Solutions for Window & Wall Systems.

Window and thru-the-wall equipment comes with installation, access, sizing and replacement challenges that are very different from conventional central HVAC.

Jarman focuses on these systems specifically. From a straightforward window-unit replacement to a difficult high-rise retrofit, we evaluate the equipment, existing opening, support, sealing and surrounding conditions before recommending the appropriate approach.

No Mini-Splits. Our focus is window units and thru-the-wall heating and cooling equipment.
Why Specialized Service Matters

More Than Simply Putting a Unit in an Opening.

01

Proper Fit

Equipment dimensions need to work with the window, sleeve or wall opening already in the property.

02

Secure Support

Window and wall systems require appropriate support for safe, stable long-term installation.

03

Weather Sealing

Proper sealing helps reduce unwanted air and moisture infiltration around the installed equipment.

04

Building Conditions

Apartments, condos and high-rises can bring additional access and installation considerations.

Our Process

Clear Service. Practical Solutions.

We start with the existing equipment and space, then determine what makes sense for the property rather than forcing every customer into the same solution.

Service Questions

Common Questions About Window & Wall HVAC.

Window and thru-the-wall systems have different installation, replacement and maintenance requirements than conventional central HVAC. Here are answers to a few of the questions Jarman hears most often.

No. Jarman specializes in window and thru-the-wall heating and cooling systems rather than ductless mini-split equipment.

That focused approach allows the team to concentrate on the installation, fit, replacement and service challenges that are specific to these systems.

  • Window air conditioning units
  • Window heating and cooling systems
  • Thru-the-wall equipment
  • Existing wall sleeves and retrofits

For general information about room air conditioners, review guidance from the U.S. Department of Energy .

In many cases, yes. The existing sleeve and wall opening first need to be checked for dimensions, condition and compatibility with available equipment.

If a direct replacement is not available, Jarman can evaluate whether a retrofit or another installation approach is appropriate for the space.

  • Existing sleeve measurements
  • Wall-opening dimensions
  • Replacement-unit compatibility
  • Support and weather sealing
  • Finished fit around the new equipment

Proper sealing can also help control unwanted air leakage. The Department of Energy provides additional air-sealing guidance.

Yes. Jarman works with window and thru-the-wall systems in apartments, condominiums and high-rise residences as well as traditional houses.

Multi-unit buildings can involve access, sleeve, opening and installation conditions that differ from those found in a typical single-family home.

  • High-rise residences
  • Apartment buildings
  • Condominium communities
  • Existing wall-sleeve installations
  • Custom fitting when required

Customers researching residential efficiency can also find useful information through ENERGY STAR .

In many situations, an older opening or sleeve can be adapted for updated equipment. The dimensions and surrounding construction need to be evaluated before determining the appropriate approach.

A good retrofit addresses more than appearance. Support, equipment fit and weather sealing are all important parts of the finished installation.

  • Measure the existing wall opening
  • Evaluate the existing sleeve
  • Compare replacement dimensions
  • Address support where necessary
  • Seal and finish the installation cleanly

Learn more about controlling air leakage around building openings from the U.S. Department of Energy .

The right choice depends on the age, condition and performance of the existing unit as well as the type of repair it needs.

Jarman can evaluate the current setup and help determine whether repair, replacement or retrofitting is the more practical approach.

  • Age of the existing equipment
  • Repair history and current condition
  • Heating or cooling performance
  • Cost and practicality of the repair
  • Availability of compatible replacements

The Department of Energy also provides information about efficiency and proper room-air-conditioner sizing.
