1. Question: What is a retrofit PTAC unit?
Answer: A retrofit PTAC unit is a replacement PTAC unit that has been designed to match older PTAC units that are obselete. This allows the installer to utilize the existing wall openings, saving major renovation costs.

2. Question: How do I determine if I need a retrofit PTAC or a standard PTAC?
Answer: Retrofit PTAC units are for replacing old PTAC units with unique dimensions or accessories. If you are replacing an existing PTAC unit, measure the existing wall sleeve. If your existing wall sleeve is approximately 42-1/4"W x 16-1/4"H, most standard PTAC units will work fine. If your existing wall sleeve dimensions are different, you can either rip apart your wall and re-frame the opening, or install a retrofit PTAC unit.

3. Question: Are other replacement PTAC units available that are not shown on your list?
Answer: Yes, we can have a custom PTAC unit built to match your application. Minimum order quantities may apply.
