Four Suns Heating & Cooling, Inc.

This company was awesome. Rich was thorough and didn't mind answering all of my many questions. He explained what he was going to be doing as well as detailing why we needed a new AC unit and what steps to take next. They worked with our home warranty company and scheduled an appointment for the installation right away. I would highly recommend this company.

Called another company that starts with the first letters of the alphabet and they told us we needed to replace our 50 gallon water heater. The “technician” who was sent pointed his flashlight at it and said we needed a new one. Ours had been heating inconsistently but had worked off and on the past week. They charged me $60 for him to look at it and tell us $3800 to replace it. Said thank you, paid the $60 for nothing, and showed their “tech” the door. Called Four Suns who has done work before - not sure why I didn’t call them first. Their technician Tim came out same day, cleaned it, fired it up and all good. No need to replace, just $85 for his time to actually fix the problem while diagnosing it. Plus his quote to replace is TWO THOUSAND LESS than XYZ (other alphabet letters actually) at only $1800. I will always call Four Suns first!!!

We recently moved to the area and needed our new (to us) furnace looked at. We hoped when we called Four Suns that they wouldn't take our money and leave us high and dry. Our furnace was working well when it worked, it would just stop working sometimes making it difficult to find the problem. I called, they told me how to work with it and then proceeded to be even more amazing every step of the journey. They came out and when they needed to look further into the problem, they worked with our past payment and home warranty. They are above and beyond an honest, dependable, competent company. Absolutely call them if you need any heating or cooling work!

I've been using Four Suns for all of my HVAC needs for ten years, over the ownership of two homes in Naperville. They replaced the furnace in my old home and just recently replaced the furnace and the entire AC system in my new home. I've never had any reason for a single complaint with them. They're always on time, they always do the work well, and they're always incredibly polite. Jason will take the time to explain everything to your full satisfaction. Most importantly, in all the work they've done for me over the years, I've never had to have them back to fix anything up! Even more importantly, I have the utmost confidence that should any problems arise, they'd be there in a heartbeat. This group takes great pride in their work, and it shows.

I just switched to Four Suns for my annual furnace cleaning based on a neighbor's recommendation. Everything I heard about the company was true. The company I used to work with was "suggesting" that a new furnace might be in order. It is only 15 years old. Rich from Four Suns did a thorough check and assured me it was in good working order. He also discovered an issue with my humidistat that I was unaware of. It was apparently not working at all through the last heating season, something the prior vendor did not detect. I will be staying with Four Suns from now on.

This is my second house that I have used Four Suns for and they are quick and most importantly honest. A simple door switch was the issue and in addition they quickly cleaned the burner on both my units and kept my out of pocket to a minimum. Rich was also able to explain why the issue occurred. I will only use them for all my HVAC needs.

We have used Four Suns a few times now for repairs and routine maintenance. They are always very helpful and professional. They show up when they say they will and completely explain the service they are performing. Our air went out this summer on one of the hottest days and they were there in a couple hours. Can't beat the service!!

Great people to work with! We have been very pleased with their service over the past few years that we decided to have them install a new AC & Furnance. The whole crew was great and did an amazing job. We are very happy! I highly recommend!

Great group of guys, honest, reliable and affordable. Called them last night and they were here first thing in the morning. They have always serviced my furnace and ac.. will never call anyone else.. If you want great service call Four Suns (Jason and Rich), you will get great service.

We've been using Four Suns now for many years, and John and his entire crew are hands-down the fairest and fastest and nicest HVAC folks we've ever hired. We warmly and without reservation recommend Four Suns to everyone in need of an HVAC company they can count on!
