  I had a great experience with Deljo HVAC Services. They came out quickly and repaired both my AC unit and my tenant’s AC without any hassle. We were dealing with low coolant and dirty fan issues, and the technician thoroughly cleaned everything and got both systems running properly again. Jonathan McLin spent about three hours making sure everything was taken care of. He was professional, friendly, and incredibly attentive throughout the entire visit. What I appreciated most was that he explained every step of the process, so I always knew what was being done and why. It’s hard to find service companies that combine speed, quality, and excellent customer service, but Deljo HVAC Services delivered on all three. I truly felt taken care of, and I highly recommend asking for Jonathan McLin if you need HVAC service. I wouldn’t hesitate to use Deljo HVAC Services again.

  Marek Slomba was the senior technician in charge of my complicated furnace replacement and his work is excellent! And he is pleasant and a terrific whistler. The more difficult the work, the better the whistling. He is highly recommended. In addition to being an excellent installer, he is a kind person who listened to my concerns and understood my needs.

  We had a great experience with this heating and cooling company! After our air conditioner unexpectedly stopped working during a heatwave, they were quick to respond and walked us through our options without any pressure. The installation team was professional, punctual, and respectful of our home. They replaced our entire AC system efficiently, answered all of our questions, and made sure everything was working perfectly before they left. The new system is running great, and our home is finally cool again. We really appreciated the excellent communication and quality workmanship throughout the entire process. I would definitely recommend them to anyone looking for honest, reliable HVAC service!

  Wanted a review, evaluation and maintenance of our air conditioning system. Deljo technician Gregory was exceptional in his service, taking apart the compressor, checking the thermostat, the return and delivery vents and everything in between, explaining how it all works. The system has emitted a low grumbling noise recently and Gregory explained how the ball bearings in the motor are wearing down, with an estimate of the cost to replace the motor.

  We had a very positive experience with Deljo. Everyone we worked with: Jesus, Tyler, DJ & Adrian were so helpful and knowledgeable. They arrived on time, were courteous and took the time to answer all our questions and explain everything clearly. The service was thorough and the installation by DJ and his team went smoothly. We appreciated the honesty and professionalism throughout the visit. It’s refreshing to work with a company that is responsive, reliable, and focused on customer satisfaction. We would definitely recommend Deljo to anyone looking for trustworthy HVAC service and will use them again in the future.
