Heating or plumbing emergency? We’ve got you covered!

Edgewater HVAC Services for All Your Heating & Cooling Needs

When your heater or air conditioner stops working, the last thing you want to do is interrupt your day with a search for trusted HVAC companies. It’s so much easier when you have the number stored in your phone and know that when you make the call, your certified technician will arrive promptly and do the job right the first time.

Deljo Heating, Cooling & Plumbing has been providing superior HVAC services to Chicago residents for over 100 years. Our technicians have the experience and skill needed to efficiently and effectively diagnose and repair your HVAC issues.

HVAC Inspections & Maintenance Services

Annual or biannual HVAC maintenance is highly recommended during spring or fall months. These visits allow your technician to clean, repair, or replace any worn or broken components in your system that might prevent it from running properly throughout seasons of extreme weather.

Regular heating and cooling inspections are the best chance your HVAC system has for a prolonged, efficient lifespan. Consistent efficiency allows you to keep your utility bill from spiking, as well.

Edgewater HVAC Repair

Any time your heater or air conditioner stops working properly or indicates a problem, call immediately to schedule a service visit. Our NATE-certified technicians will quickly assess the issue and fix the problem, allowing you to return to your normal routine without worrying about how long your HVAC system will hold out. The longer you delay heat or AC repair, the greater the likelihood of a small problem becoming a large one.

Heating and Cooling Installation

Most heating and cooling systems last between 10-15 years, depending on the technology and maintenance history. When your HVAC system needs to be replaced, rely on Deljo Heating, Cooling & Plumbing for prompt, professional service. We carry only the most respected brands and guarantee customer satisfaction with every visit.

When you want to upgrade your heater or AC unit, or would like to install a brand-new one, we can help with that, too. If you are unsure as to which type would be best for you and your family, we will be happy to provide a professional recommendation to suit your needs and budget.

24-Hour Emergency Heating and Cooling

Because we truly care about our customers, we offer emergency HVAC repair services 24 hours a day, 7 days a week, 365 days a year. HVAC problems don’t cater to business hours so neither do we.

A heater failure in the middle of winter can especially be a cause for concern. We never want your safety to be at risk, so Dejo Heating and Cooling is only a phone call away. You can rely on us to be there for you when you need us.

This was my first time as a Deljo customer, and I was very pleased. My technician, Giovanni, was very thorough and diligent. He serviced my furnace and identified a faulty sensor that was causing the unit to shut itself down. Deljo ordered the part, and Giovanni replaced it a few days later. Overall, the team at Deljo was great. The dispatcher kept me informed about Giovanni’s arrival time, and the supervisor assisted Giovanni when he was diagnosing the problem with the furnace. I highly recommend Deljo.

I’ve used Deljo for over 10 years now and they always do a good job. Izzy was the technician for this visit and he did an excellent job with my winter maintenance on my multiple units in the household. He also addressed an issue while cleaning the furnace blower wheel. His communication was clear and concise with what he planned to do to address the issue quickly. He was confident and I had 0 concerns or questions. Great job Izzy!

Paul was great! Arrived on time and completed maintenance on my humidifier, tankless water heater, and two furnaces. All work was performed under my Gold Star maintenance program, so all maintenance charges were covered. Paul did provide a few proposals for additional services on furnace & tankless water heater, but those were emailed to me for further consideration. Paul was friendly, knowledgeable, and answered all my questions.

Gabe did an excellent job with our annual service visit. He arrived in the early part of our service window, was friendly and knowledgeable, and got the work done in a very reasonable amount of time. I have great confidence in Deljo, and am a long-time customer.

I’ve been using Deljo for 20 years for HVAC but now venture into enlisting their plumbing services. Bashar was very courteous, efficient & informative, and I’d definitely request him again for the next plumbing job. Great experience!

Working with Deljo is always a good experience, and today’s appointment with Izzy was no different. He was able to come early which actually worked better with our schedules, but called me ahead of time to make sure that was okay. He was friendly and knowledgeable when he explained the work he had done during his visit and our options for fixes. He was also able to schedule a quote appointment for us while he was still here. We would highly recommend working with Izzy and the Deljo team!

Drew performed the seasonal maintenance on my AC. It needed some repairs and updates and he was able to fix everything at the same appointment. He also noticed issues with the hot water heater and we were able to get ahead of that, as well.

I would leave six out of five stars if I could! My technician Jorge went above and beyond on his service. There was buildup in the rental property’s toilet from the previous tenant. One maintenance person did a surface level job of cleaning but did not fully remove the obstruction. Jorge went above and beyond and came to a solution and even explained the perpetual problems older toilet models can cause. Moving forward with this insight, I can perform my own upkeep the previous tenant did not. Thank you kindly!

We just had our new boiler installed by Jonathan and Carlos. First rate work! They arrived on time, removed the old boiler, installed the new unit, and explained the features. Both guys were pleasant. Bring on the cold this winter! We are ready thanks to the team from Deljo.
