Retrofit Overview

There are many reasons you might need a retrofit. If your equipment is nearing the end of its lifetime and is in need of a large-scale repair, in most cases you can get more value out of replacing with new equipment under a new warranty.

 Or maybe your family has grown and it’s time for a bigger water heater to handle the extra washroom, laundry, and dish washer activity.

Perhaps you have small children and pets, and your home’s air quality could be improved with an air purification system.

Or, it’s the dead of winter and your furnace’s heat exchanger suddenly cracks, leaving you in the cold.

Not for long. No matter the situation – emergency or a planned upgrade – we can help you with a custom retrofit to your plumbing, gas, and HVAC systems.

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. Simple. Additional warranty coverage can be gained through registering your products with the manufacturer. Call our office to inquire about these programs.
