The place you share with those you love most;
your haven in a busy world.
A place whose comfort we're here to protect.
From winter's chill through the dog days of summer, our primary goal at CUSTOM DESIGN is to keep your home comfortable for you and your family.
But, that's just the beginning. We also offer you peace of mind, ensuring your equipment operates safely. We help you save money on your fuel bills. And, we help deliver relief to those with allergies and many others concerned with the quality of the air they breathe.
You'll find we take our job seriously and value highly the trust that is placed in us. To understand why we go so far beyond what others do by investing in the extra training and equipment we believe necessary to protect your home and family properly, take a moment to view our short 30 second video that best explains "why we do it"...and "why it matters."
By doing what it takes to ensure each customer's complete satisfaction, CUSTOM DESIGN is welcome in more homes in Nassau and Suffolk Counties than any other contractor. We invite you to give us a call.
