Client Testimonials

I always use Deljo. The entire staff is amazing from intake calls to install. They were fast, professional and gave us a fair price.

~ Monica OConnor

Joe was great. We came home to a cold house on a Sunday night and he came out to diagnose the issue right away. Very knowledgeable, very friendly.

~ Kyle Sant

We’ve been using Deljo for several years and have had a great experience with them. They’re prompt, reliable, and trustworthy. The technicians (David was the most recent) have been great.

~ Ari Telisman

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working. Called Deljo back immediately and they sent out Matt and Aaron that same evening and they were able to resolve the issue without having to order a new part. They were professional and courteous and didn’t stop until they figured out the problem.
