Alberto is courteous and very skilled and knowledgable. We are pleased to have him as our service man.
2/4/17 – Mario
John was GREAT! He answered all my questions & gave me some ideals to take care of some problems. He went as far as following up by having some one set an appointment for possible corrections.
2/2/17 – Heather
Javier was fantastic. Called ahead and gave us heads up for arrival time and extensively took care of our HVAC. Highly recommended!
2/2/17 – Francisco
Pleased with the prompt response to our repair needs. They are always very professional on the phone be it a secretary or a technician.
2/1/17 – Robert
Tony showed up right on time and did an excellent job. He was very good at explaining what needed to be done.
1/26/17 – Ronna
Mike was an excellent technician, as usual. He performed his job efficiently and answered all my questions.
1/11/17 – Jared
Dave Estes was extremely professional, nice, and did a great job. He worked fast and answered all of my crazy questions. I would recommend Deljo to all of my friends and family. Thanks!
1/10/17 – Kim
Chris is a great tech. Very thorough; explains issues and options well.
1/2/17 – Kevin
Deljo just replaced my furnace, Steven and Alex did a phenomenal job, extremely happy with my new top of the line furnace!
12/15/16 – Suzy
Deljo was not the cheapest option for me, but I decided to go with them for two reasons. 1) Deljo has always been honest and they don’t try to sell me parts I don’t need when they come to service my equipment. I trust them. 2) The product they provided had a better rating on Consumer Reports.
12/15/16 – John
Excellent service from Deljo, as I have come to expect. Brandon and Casey were most helpful in installing two new furnaces, which seem to be working well in this deep freeze weather. Brandon was patient and clear in explaining about new thermostats and filters.
11/22/16 – Eric
Javier was thorough, efficient, cordial and honest. Fixed our furnace with a simple workaround, explaining that although it didn’t address the root cause of a busted intake pipe where it met the alley, it was equally effective and much more affordable (no extra charge) than replacing it.
10/26/16 – KT
Professional, competent, thorough, timely, easy to work with — Jay, David, Brandon, Mike, and Beth were all so friendly and responsive to our needs. I especially appreciate the time taken to explain choices and to get the job done right. We’d been limping along with “the guy in the white van” for years. Deljo is the real deal.
10/26/16 – Kathy
Could not be more pleased with the installation and communications between myself and Deljo. The entire TEAM was in sync. I have 3 other properties in Illinois which means I have been involved with several installations of various kinds and can truthfully say that in this case you DO GET WHAT YOU PAY FOR and more… professionalism and courtesy!
10/18/16 – Rose
Tony, Charlie, Chris, Bob….all these people were fantastic. And so very very prompt! They made sure things were working properly and wouldn’t quit until they were. I’m very glad I found Deljo.
10/4/16 – Robin
The technician was on time and very polite. He also explained things clearly
10/1/16 – Scott
The service person who showed up was professional, nice and thorough in his work.
9/30/16 – Cindy
Steve, Alex and Bob were amazing! We had two quotes for a complete new furnace and AC unit, replacing a 60 year old furnace. Deljo was slightly more expensive but you do get what you pay for. Their knowledge, expertise and helpful attitude exceeded our expectations. Such nice people, not only do you not mind having them in your house to do the work, I would have loved to have them for dinner! Honestly, home improvement can be so difficult and Steve, Alex and Bob made it easy! Robinson also did an excellent job cleaning our ducts. I would not hesitate for a second to refer you. You did what you said you would do and with big smiles on your faces. Thanks for making our first major project in our new home a success!
9/30/16 – Lowell
The Best. When I was in the HVAC business 40 years ago I knew what good Techs where. The two that installed my system were great , Kudos to DelJO
9/14/16 – Larry

9/9/16 – Tim
Mike called to let me know know he was on site and followed up afterward to tell me all was well with my HVAC.
9/4/16 – Howard
Deljo recently replaced the HVAC in my condo. Dave Urso, the sales rep was prompt, communicated clearly and gave me the info necessary to buy the correct equipment. He solved a problem with the prior installation that caused an impediment to opening the door to the deck so that now, there’s no issue and the deck look is improved. Steve and David, the install team were terrific. They protected the areas within the apartment from damage and debris, did a very professional job on the installation and clearly communicated the necessary info about the new equipment to my satisfaction. All in all, this was a great experience compared to others that I’ve had with HVAC contractors.
9/1/16 – Thomas M
Dave was thorough and helpful in going over our HVAC and was gracious in putting up with distractions from the large family dog and the three year old grandson, who wanted to play “catch” !
8/29/16 – Ken

Alan was very knowledgable, explained what he was going to do and provided information and recommendations about my units that allowed me to make an informed decision.
8/18/16 – Richard
Amidst a hot spell, I called Deljo to investigate an issue with my AC. I took pictures, sent them in and Stephanie responded that a Technician could come out the next day to address the issue. As planned, we received a call that Josh was on his way. He came out, inspected and assessed the unit and resolved our problem. We have used Deljo on many occasions, but I will say that Josh was SUPER NICE, walked me through what might be going on, assured me about the condition of my unit and how we use it and left the home C-O-O-L….thank you Josh and Deljo
7/22/16 – Jim
Alberto is professional, methodical, courteous, and punctual. He did not leave my loft until he was convinced the problem was solved.
7/20/16 – Krystal
Chris, the service person who came out was very professional. He explained the process for inside and out, and offered tips for recommended filters. He was very courteous and explained next steps once we learned that our compressor was not working. He even called to schedule an appointment for us to have an engineer come out tomorrow! Very impressed with his customer service.
7/15/16 – Sam

7/8/16 – Tyler

We had Deljo Heating & Cooling replace our ancient hot water heater. They showed up when they said they would, replaced the hot water heater, and were careful to clean up after themselves. Great company to do business with.
