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

Carrier Dealer in Logan Square

Since opening our doors nearly a century ago, Deljo has provided heating services throughout the Chicagoland area. When home cooling became widely available in the early 1950s, we began offering that service, too. And today we’re proud to be your Factory Authorized Carrier dealer in Logan Square and other areas of metropolitan Chicago.

In addition to selling Carrier’s wide line of heating and cooling systems, we also offer Carrier furnace repair in Chicago and beyond. But we don’t stop at just heating repair. Air conditioning repair in Chicago is another one of our specialties. With nearly 100 years of experience, Deljo is the only name you need to know for Carrier HVAC systems and repairs.

A Quick Lesson on SEER Ratings

Before covering some of the Carrier systems we sell, let’s clear up a common point of confusion. Namely, what is that SEER rating that’s often mentioned when you’re in the market for new AC units?

SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating of an air conditioning system offers a measure of its efficiency. To determine the rating, simply divide the system’s cooling output during a typical cooling season by its energy usage. The higher the SEER rating, the more efficient the unit.

Modern AC systems typically have a SEER rating ranging from 13 up to a maximum of about 25. To put this value in context, older systems offered significantly lower SEER ratings, often hovering around just 8 or 9. With that knowledge in tow, let’s take a look at a few of the superb Carrier systems available from Deljo Heating, Cooling & Plumbing, your one-stop-shop for HVAC in Chicago.

Infinity® Series Central Air Conditioner

These high-efficiency systems are built for total home comfort and are engineered to be the very best available. Some of the features of this impressive system include:

  • SEER rating up to 18
  • Superior humidity and temperature control
  • Silencer System II™ for quiet operation
  • Environmentally-sound Puron® refrigerant
  • 10-year parts limited warranty when properly registered

Comfort/Base Air Conditioners

This is another Carrier option to consider. These reliable, quiet, and efficient units provide economical cooling comfort with a SEER rating up to 18. This system runs as quietly as a dishwasher and resists the elements to run reliably for years.

Performance Series Compact Air Conditioner

The small footprint of the Compact Air Conditioner allows you to install it as close as six inches from your home. Or you can place it on your roof or even on your deck. And these superb, compact units have a SEER rating up to 15.

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.
