What to Expect

Our dedicated Retrofit department staff will help you through the complete process of replacing or upgrading your equipment. We will ask the right questions and even visit your home ahead of time to customize the equipment for your unique residential needs.

And you never have to worry about cleaning up; on the day of installation we take care of removing and disposing of the old equipment.


Hy-Mark offers several industry-leading warranty coverage programs to cover any future parts and labour service costs on your equipment. Once we install your equipment, we keep track of your warranty coverage period for you. Additional warranty coverage can be gained through registering your products with the manufacturer.
