Joe was very professional on the phone. He was helpful and got us scheduled quickly. Thank you.

Chaz was great!! Showed up on time, took care of our issue, and explained what he did. was extremely knowledgeable, polite, professional.

Will use them again when I have an issue!”

New furnace and ac installed in a day and a half
Jason Reid was absolutely awesome great technician knowledgeable professional and hard worker
We are very happy with the installation and the care we received from the company
Highly recommend them
When I discovered my furnace wasn’t working Chaz was here right away to diagnose and fix the problem. He was very professional and I will recommend him to everyone! Thank you again!!

Absolutely outstanding! We called them at 7:30am after finding out our furnace had gone out overnight and they had a tech their before 10am. Chaz, was SO amazing! Not only was he extremely professional but missed their office party to personally pick up our part and come install it before the end of his shift so we would have heat over the weekend. I cannot recommend them enough! Additionally, pricing was extremely reasonable and appropriate!

I can’t say enough positive things about my experience with Custom Engineering! Our furnace went out in the coldest time of early February & they responded immediately to us. Not only were they out to our house within two hours, they loaned us heaters when it was determined we would need a new furnace. They had the new furnace in stock and were back out to install it right away. Our dead furnace was old and a bit crazy to deal with, the guys were so professional, and worked all day until they had everything done to perfection and the old “octopus” like furnace gone and cleaned up! We had heat and it was amazing how much better it worked in our house! LOL Custom Engineering didn’t try to “up sell” anything, we had just what we needed and it has been great. Would recommend anytime!

Happy with my experience. Got a quote quick, didn’t take too long for them to get out and install my new furnace and air. Everything works great, definitely ready for summer!
