Four Suns Heating & Cooling, Inc.

If they work anything like they drive, I wouldn't recommend them to my worst enemy. Thankfully I was at least paying attention and able to avoid an accident.

I am truly impressed with Four Suns Heating and Cooling, Inc. I have an under grad degree in Mechanical Engineering and find Four Suns to be knowledgeable, trustworthy, honest and fair in their pricing. Even when I thought we needed to replace a problematic furnace, they recommended against it. When I explained the history of the furnace prior to their looking at it, they still felt they could repair it. It was my decision to stop repairing the less than 10 year old furnace and they provided excellent input on choosing a new, less expensive, more reliable replacement. I will continue to use their excellent services. I recommend them highly to anyone looking for good, honest, fairly priced HVAC work.

I contacted Four Suns to perform my first annual inspection and tuneup on my home's three heating systems. The technician was extremely professional and took great care to explain to me the operations of my three systems. One humidifier required ordering a part and a return visit for installation. A couple of days later the same technician installed the part and insured all systems were operating properly. Again he assured that all my questions were answered before he left. I highly recommend this professional and caring company. Their rates were very reasonable for the time and work involved.

I Was recommended Four Suns from a friend in Downers Grove, I’m in Glen Ellyn. I Called Four Suns yesterday 7/2, had an appointment set up for the morning of 7/3 (today). Rich came out and took care of my AC unit. Very professional, very knowledgeable and just overall stand up person. He walked me through each step of the process and explained everything He was doing. From the first contact face to face with a handshake, putting on the covers on the bottom of his shoes to come inside my house, to having my AC unit blowing cold air. He not only fixed my AC unit, but also gave me tips on how to maintain the unit as best I can. 5/5 would recommend Four Suns to every single person I can. Stop doubting and stop comparing, I’d they are available in your area please go with them. The quality and service is top notch. Thank you Rich and thank you Four Suns!

First of all, let me start by saying that I don't normally take time to write reviews, however, a review of this company is definitely needed. I run a property management company and have had the pleasure of dealing with Four Suns twice now. Some of our owners use home warranty companies (which can be difficult to get quality vendors out in a timely manner) and this is how we were introduced to Four Suns. They are not only VERY responsive (were out the same day for a home warranty call) but took care of the problem right away and were VERY professional, honest and courteous to our clients. We will be using them going forward for ALL of our HVAC calls! A lot of HVAC companies come and go but I know this company will be around for a long time due to their customer philosophy. Thank you Four Suns!

We have used Four Suns now for about 10 years and are extremely satisfied for the great work , honesty, charges, and products. We have bought our last heater and water heater from them. We have recommended them very highly to others and family. They are so great to work with and are so reliable.

I have used Four Suns Heating and Cooling for over 8 years now. They installed a new furnace here 8 years ago, my new AC unit last October., and a new water heater in January. A family run business, you'll deal with the same guys every time. It's nice to have familiar faces who know your house, and remember the history of any repairs or installations. They are extremely responsive when there are any issues. When something does go wrong, once it is fixed it is fixed. They are reliable and I have never had to call them back once they've repaired something because it wasn't done right. They are courteous, friendly, and will never try to sell you into anything you don't need. When you do need a replacement, they recommend reliable and cost effective equipment that will last. All this has kept me a customer since 2009 and I would highly recommend them.

I use Four Suns for my home and business HVAC, and they are always courteous, responsive, professional and their pricing is fair. I recently had to have my entire AC/Furnace system replaced (it was 30 years old) and they helped me review my options, make the best choices, went the extra mile during installation and helped me register my new unit for Warranty Coverage before they left that day. I highly recommend them!

We have used Four Sons several times now and can recommend them without reservation! Justin and his father were attentive, honest, responsive, and took the time to explain our options. Their pricing is fair and we appreciate that they maintain reasonable pricing in contrast to some of the other companies we have dealt with in the past.

Four Suns installed my new AC and Furnace and they have operated flawlessly for the past 7 years! But, about a week ago we woke up in the middle of the deep freeze we all experienced here in the Chicago area and the furnace would not kick on. Called Four Suns at about 8 AM, phone picked up immediately, and promises of a technician between 8:30-10:30, which seemed pretty darn good, considering the weather. At 8:15 Rich showed up, diagnosed the problem, went back for the part, installed and we were good to go! The expense was very reasonable for such prompt and expert service! I will continue to call them when the need arises.
