Company Overview

Deljo Heating and Cooling boasts a rich heritage that spans more than a century in the local HVAC sector. Throughout this time, we have supported two generations of Chicagoland homeowners and businesses with outstanding HVAC products and services. Our dedication to quality ensures that our clients remain comfortable through the harsh winters and sweltering summers.

In 1922, Del-Nard Fuel Oil laid the groundwork for what would become Deljo Heating and Cooling. By delivering thorough furnace cleaning and repair services in the Chicago region, the company swiftly became known for its excellent customer service. For the next 60 years, it continued to meet the heating demands of its Chicagoland neighbors, paving the way for the next phase of the brand's growth.

In the early 1980s, Bob Clement entered the scene, acquiring the well-regarded company and taking charge. This modest five-person team upheld the tradition of excellent service that had defined the Del-Nard brand. Soon after, Bob welcomed his brother Bill to the team, and their partnership helped the business thrive. The cooperative effort between the Clement brothers gradually transformed into the large family-owned operation that Deljo Heating and Cooling is today. The foundational legacy established a solid groundwork for the company's future achievements.

As owners for over 30 years, Bob and Bill Clement have committed their lives to the HVAC business. Deljo, being family-owned and operated, ensures that both employees and customers are treated with familial care.

Tyler Bauers was most courteous and polite, showed up after hours and was delightful in manner and articulate and energetic and quick in his service. He explained in detail the issue and fixed it immediately. We greatly appreciated and enjoyed his showing up with all of his professional service so determined and complete; and his personal presence so thoroughly professional and informative. We also wish to acknowledge your elder service man/statesman Tony Sarrono. What great gentlemen these two. We are delighted to have them both in service to us in our home. May they be acknowledged as exemplary. Thank you.

Service tech called before he arrived, was super friendly, and completed AC maintenance work in professional manner as usual.

Your technician showed up on time, wore a mask, explained everything he was going to do, completed all the checks, and gave us recommendations for improvements we could make. All was done quickly and efficiently.
Good job!

We had an annual service agreement with a firm purchased by Deljo and carried it over. As part of the agreement we had our spring maintenance done the first week of May 2021. The technician was not thorough. After charging us $500 for sealant and refrigerant(on top of the $450 maintenance agreement), he left. The first hot day in mid- May- the unit blew only hot air. After calling Deljo, they scheduled another technician to come out, they tried to reschedule for several days later but we refused. That technician admitted that the first guy had overfilled the compressor and could have ruined the A/C unit. He indicated he didn't have the necessary equipment to fix the unit and we needed to rescheduled a third time. A different tech came, claimed to have fixed the issue ;and on the next hot day- no A/C. We will also add the we received no refund for the over charge, no call back and no request for feedback.
We hired another provider who had a much more competent approach and they recognized the issue immediately and after 2 hours or repair solved the problem.
Our sense is that the quality of Deljo's work is unfortunately not up to their competitors in the Chicago area.

Had AC lines that were freezing up so we called American Home Heating and Air that we have used for the past 15 years to send someone out. My wife handled setting up the appointment and I guess this place bought American's phone number when they closed up shop because they were the ones that showed up to look at the unit. Well we were quoted $375 to replace a capacitor (which runs about $8 on Amazon and is secured by 2 screws and 2 quick connect wires) and $708 to clean the blower fan motor. No breakdown of labor, parts, time etc...just a number. It was also suggested that we speak to a 'comfort specialist' about replacing our entire system as it was 'old'. Obviously we went a different direction.

Another company comes out takes 5 minutes to figure out the blower motor has some electrical issue and is running too slowly therefore not moving enough air and needs to be replaced. 60 minutes later the motor and mounting bracket are replaced the system is recharged and everything is once again running great. Cost us $380 for new motor, mount, capacitor and system recharge.

To be fair, the gentleman that made the service call from Deljo was extremely professional, neat, kind, punctual and well spoken. He was upfront about the costs as well but didn't really have any answers for why the prices quoted were so high. We paid the fee for the service visit and let him know we would not be moving forward with them.

There are far better options available in this trade space. Look for the guys with several hundred 5 stars Yelp reviews instead of this 3.5 star company. You'll save yourself a lot of money.

**I live in Chicago, IL. Don't know why it says San Fran on the review?

Have been a Deljo goldstar customer for many, many years. They are consistently helpful and professional. Everyone from the office staff to the maintenance/repair team to the sales support are well trained and courteous. The few problems we've had in 20+ years have been addressed promptly and completely. I trust the Deljo team and recommend them highly.

Tech tells me cleaning my unit was going to stop my furnace from shutting down. Quoted me $2,200. Blown away by the price but below zero temps so they take advantage knowing there's no choice. I asked if 100% sure that would fix my issue as I do not want to pay all that for nothing. I was told YES. after the cleaning I am told ""well looks like the issue might be something else""!!! Tech tells me he will call his boss to see if he can reduce the cost since he was wrong. Of course his greedy boss doesn't back up what his own tech guaranteed and says no. Here am below zero temps, $2,200 down the drain and freezing with kids in the house. It's disgusting how these clowns just steal by lying. Their justification was ""well your unit was going to need the cleaning eventually anyway"". I NEED HEAT NOW NOT WORRIED ABOUT EVENTUALLY!!

Update. New HVAC company fixed my furnace today within 30 min. All I needed was a $90 dampener. My unit is working perfect now. Service I received yesterday was not needed and what I was told was untrue. my heat exchanger wasn't fully cleaned yesterday even though 1150 of the 2200 I paid was for that. I had it checked. The written recommendation to have my unit replaced I was told is ridiculous. My unit was built in 2018. All excuses given to me by Deljo were after they charged me 2200. Had they said it before their ""guarantee"" I would have declined service.

Yes, they got my furnace up and running. But, it was highway robbery. I have used this company twice now and only in an emergency when I couldn't get any other HVAC company. Literally, not even from the suburbs. This vendor is the very last one I go with because every-time the rake me across the coals.

This time I was banged almost $300 for cleaning a flame sensor. You may ask...how hard is this? Let me tell you. Often, it is 1 screw, removal
of a metal prong sensor and then using a wire brush, sand paper or special cloth to clean soot off the sensor. Then re-install. The job takes all of 15 mins. 30 mins tops. To be generous it's 45 mins after arriving on-site and diagnosing. Had I been in town, I would have done this in my own. But, nope, got it busted off in my ass for being on site 35 minutes and wire brushing a metal rod the size of a paper clip.

Save your money and go with anyone else but this company u less you feel like paying a kings ransom.

Had a tech come come out to my home because I had no heat for 3 days. Tech proceeds to read previous notes from last repair and says he can not do anything because it's too dangerous and difficult to fix. Charged me $109 !!!! This could have been done before someone came out instead of on-site. I ask why.. tech tells me why by reading notes from previous tech. I ask for the notes because we just purchased home and information was held from us by previous owners. The owner of Deljo Bob refused to give info, only way would being subpoenaed by a lawyer. Then I ask them to have a sales person come out to give me quote because my family is without heat. They quote me a crazy price because they knew I was desperate.... I called another company had then come the next day and install the same quoted furnace for $3000 less. Stay away from this company !! They only care about their pockets. I am out $109 and no chance at getting money back from previous owners because of Bob. Hope you are happy by Treating families this was during these difficult times. Shame on you Deljo
