Customer Reviews

This was my second time using Kulacz and Sons! Both times were emergencies. I am so pleased with this company. They are honest and will not try to sell you something you don't need, unlike one company in this area. Their prices are great and again they won't over charged you. 

John went above and beyond expectations! I'm putting this review on social media! This is the go to company for your HVAC needs!

New Air Conditioner & Furnace

After meeting with 3 heating & cooling companies, we selected Kulacz & Sons to replace both our air conditioner and furnace. The professionalism and courtesy were exceptional from the estimate to the installation. 

The technicians arrived at the exact time I was told, and they worked efficiently and neatly. With the exception of the shiny new furnace and air conditioning unit, there was no trace that they were there at all. I highly recommend this company!

Furnace Replacement

I recently had my furnace go out and Kulacz and Sons were at my house within a few hours. Come to find out it was beyond repair so after a great explanation from there service tech we decided to go with a new furnace after I got a few estimates. 

I decided to go with them they were the most reasonable priced. They installed the next day and were very professional and left our house the same way it was. 

Very respectful and professional through it all. I highly recommend them!!

New Furnace and Air Conditioner

So glad to have found Jake who was beyond professional through the entire process of having a new furnace and AC installed. He met with me personally to discuss every detail of the products and my choices/options and his crew did an excellent job on every aspect of the installation. 

Was quick to answer calls and very helpful on the financing side as well. Appreciate the great customer service!

New Furnace and Air Conditioner

We started using Kulacz & Sons last year based on my married daughter's recommendation. This year Jake came out and serviced our AC and said it would probably last through the summer but it was 18 years old and not running efficiently. Over the course of a couple of weeks we decided now was a good time for us to replace the furnace and AC.

Jake came back and showed us the various systems we could have installed and left it to us to make our choice. A few days later Jake and Austin installed the new furnace and AC in a very efficient and professional manner. The installation looks like the equipment has always been there. They cleaned up after themselves and removed the old units.

 We have already recommended Kulacz & Sons to several of our relatives and friends.

Kulacz & Sons is a company I am so glad I found and will use for years to come. Jake came to my home and worked his heart out. On both service occasions I was extremely happy with the outcome. 

I had been using a different company for years until I met Kulacz & Sons - there is no comparison. I have been treated well, fairly and the company is most professional . You will not be disappointed! They are a 5 Star company with 5 Star employees - CUDOS! Barb K.

I called Kulacz and Sons for service for my central air conditioner unit. I spoke with Jake on the phone and he was very friendly and able to come out the same day for the service call. He is a complete professional and very knowledgeable.

 He was able to service my air conditioner without any issues and was very helpful explaining everything that I needed to know. Will definitely not hesitate to call this company again for any other heating and air service needs.

I just moved to Chicago from California and know nothing about heating and cooling. To be honest I never had to use either. My first winter in Chicago has been extremely challenging and I am learning more about the frigid cold than ever before. The past week I have noticed that my heat did not seem to be heating as well as it did in the beginning of the winter. I didn't know if it was from the colder temperatures or if my heater was slowly dying on me! I started to call around to local companies and it was like everyone was almost laughing at me...this girl just wasn't used to the cold. No one offered to come out they just tried to fix the problem over the phone. HELLO, I know how to use a thermostat. Thank You.

Then I called Kulacz and Sons and talked to a wonderful woman who gave me some troubleshooting ideas. After those things were unsuccessful she offered to send someone over right away. RIGHT AWAY. All the other services were offering me next week service!!! An extremely helpful and caring gentlemen came over and found that there actually WAS a problem with my heater. I wasn't crazy!! He fixed it right away. Now I am sitting nicely in this below zero freezing-ness with a nice warm furnace. It was very inexpensive and to be honest I would have paid a lot more for the efficiency and the service.

I totally recommend Kulacz and Sons for your heating and cooling. I have already recommended them to all my co-workers. You can tell they are a family run business because they actually care.
