Four Suns Heating & Cooling, Inc.

I am a regular customer of Four Suns Heating and Cooling for maintenance and repair of my furnace and A/C. My units are older and can be a challenge. Each time they are called, the work is explained and completed as described. They are punctual, professional and thorough. I highly recommend Four Suns.

I needed my furnace humidifier repaired. The first place that came out tried to tell me I needed a new unit and it would likely set me back $400-$500. I called Four Suns and explained my situation over the phone and they told me it's very likely it's just the solenoid that needs to be replaced. They came out the same day and sure enough that's all it was. They replaced it, and the humidifier works great now. For prompt service from a company that knows their stuff and won't try to upsell you into something you don't need, I highly recommend Four Suns.

Our air conditioning went out and they came out the very next day. These guys were great! They explained everything that was wrong with our furnace, showed me what happened and replaced/fixed everything within the same day. Very informative and honest. We just moved to Naperville and I am glad we found them. They were highly recommended through Angie's List.

They said that we needed to replace our capacitor and so we had them do it for 40 extra dollars . However the capacitor that they installed was wired incorrectly and our air conditioner failed at least three times in the following 3 weeks failing to blow cold air. They miss wired the capacitor in a way that would likely cause further strain on the compressor which we hope was simply accidental and not done maliciously. After putting in many hours of research we were finally able to discover what the problem was and fix it. We had them out for a simple yearly inspection because everything says that's what you're supposed to do but our air conditioner ran perfectly for 9 years and we only had issues after they came out and inspected it and replaced the capacitor. On the plus side they were on time and very polite however we will not be calling them again.

Four Suns is a family owned business and we have had nothing but pleasant experience with them. This is the 3rd time we used their service.

Our AC broke down just before the first heat waver to hit Chicago at end of June. Called Four Suns and they came out the next morning to check the unit. As it turned out we needed a new AC. Four Suns managed to squeeze us in their busy schedule and installed a new unit the next day, just in time before the temperature went up to the 90's.

I am so very satisfied with this company. From the first phone call to a timely arrival to a job well done. The tech that came to the house was very friendly, told me what he was going to be doing and was very polite.
I would definitely recommend this company and will for sure call them again. Also, the prices were very fair. Thank you.

Jason and his team are prompt, offer quality service and are very knowledgeable on all things HVAC related. We have used them many times and are happy with their service.

I switched my business to Four Suns about five years ago and have always found them to excel in customer service at a fair price.

Quick response time in emergency situations as well!

Call them for your heating and air conditioning needs.

These guys are the best and that's why we have been using them for over ten years. We own a lingerie boutique (Elegance Underneath) and one morning there was no heat at opening time. Mind you, it's January in Naperville so you can't have women trying on bras when its 52 deg inside. One call to Four Suns and John & Jason were out in no time and had it nice and toasty warm. It was fixed right the first time and for a fair price.

Four Suns Heating & Cooling was professional, prompt and reasonably priced. They replaced our AC unit quickly and provided us with the product information we requested. I would highly recommend working with Four Suns.
