HVAC reviews in Naperville, Illinois

I have nothing but good things to say about Josh and the team. From scheduling, to communication we have been very pleased with our service. Highly recommend.

Josh called to find out if he could come early, we were more than happy to have him. Came to clean the furnace, always courteous when he’s here. Love seeing him wear pink!

I like that Josh let’s me know when he is on his way to my home for my appointment. Today he had Bill with him to do check-ups on both furnace and air conditioner (I forgot to call for that).
They put their shoe covers on and had both systems cleaned up without a problem.
It’s nice to see the same person at my house every year.

Mike and Nik did a great job. Both were very friendly and did a great job explaining everything. Spent extra time to make sure everything was working correctly. Did a great job cleaning up afterwards. Extremely happy with the service they provided.

Our furnace went out during sub freezing temperatures. They responded quickly within a couple of hours and got our furnace back up and running. Very happy with the service and the pricing. Highly recommend.

We had the absolute best experience! This company is honest, reliable and professional! Their customer service is exceptional, often times handled by the owners themselves!
Our two installers were polite, kept us informed along the way, extremely tidy and just generally two great guys to have in your home😃

Everyone at A All Temp was very helpful! They were willing to work with us on a new furnace and the repair men (Layth and Nick) and Michael who can out to diagnose the problem were all very friendly and professional!

Josh S was an overall great tech. I asked him a few questions on my HVAC unit and he gave me the info and pointed out what I needed to be aware of. Super helpful and nice guy. Would definitely recommend Josh and A-All Temp over your typical giant heating and cooling companies.

Mike was able to get to us much earlier than promised and identified the problem. We moved into our home 8 weeks ago and have lost heat 3 times. I worked in the trades years ago and thought that there may have been some problems with the installation (done by another company). Without any prompting, Mike pointed those same issues out to me. We agreed on the price and he made the repairs.
I absolutely will use A-All Temp again!

Mary was great with scheduling me right away. Josh showed up and was great explaining the problem and made the repair quickly. I recieve texts when the technician is on his/her way and once the service has been completed. 5 STARS

Josh was amazing. He quickly diagnosed and fixed the problem. He also does a great job explaining the issue and how to help prevent it in the future. We’re always very pleased with Josh.

Josh has been fantastic! We first started working with him a few months ago for our regular boiler maintenance, and since then he has been back a few times, notably today when we had a big leak in our expansion tank. He is always timely (in fact usually early which is much appreciated),
knowledgeable, professional, and friendly. Today he arrived within 15 minutes of my initial phone call and took great care of our expansion tank leak. Thanks Josh and all-temps for the great service, happy we are in such good hands!

We replaced our 23 year old AC unit and furnace with high efficiency models. Mike, Layth, and Bill did the install and were very professional. One month later and everything is working flawlessly - no surprises. They worked efficiently and were able to finish the job in one day. They also did an exceptional job explaining everything to me and I appreciate them cleaning up the working area when they left.

Josh came out to fix a separate problem with our other AC unit and was able to identify the issue quickly. He was thorough and I appreciate him walking me through the repairs that needed to be done.

We received a few different quotes and thought the pricing for the AC and furnace was fair. Most importantly we wanted a reputable company to do the install and we were not disappointed. We will use All Temp again in the future and recommend them to friends and family.

Thank you again Gary and Jake of Anytime Heating. Our April Air thermostat was not working. I called Anytime Heating and left a message and Gary called me on a Sunday to make an appointment for early Monday morning. Jake fixed the thermostat and the humidifier is running fine. Anytime Heating always goes the extra mile to help their customers. They treat you like family. We have been with them since our home was built in 2007 and would not trust any other company.

Mike is the absolute best, he’s efficient, and knowledgeable and offers great recommendations for products! I honestly can’t say I’d go to anyone else! Where Mike Goes, I go!

I recently had HVAC system maintenance and diagnostics performed on my Carrier high-efficiency furnace, and I wanted to share my experience.

The technician, Josh Stubbs, was outstanding. I was very impressed not only with his technical knowledge and recommendations, but also with the time he took to educate me throughout the process. I have worked with many HVAC technicians over the years, and he is by far one of the best.

Josh demonstrated high integrity, deep expertise, and a genuine commitment to doing things the right way. The overall service experience was excellent.

Given the age and condition of my current system, I asked for a proposal on a new unit, and he has been extremely helpful there as well - walking me through options, as well as researching available credits and rebates.

I would highly recommend Josh and his firm to anyone looking for knowledgeable, trustworthy HVAC service.

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!

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 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 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!

We contacted Jason at Four Suns as a recommendation through our subdivision Facebook group because our furnace motor was making a strange noise. He was able to come by within a 1/2 hour and quickly diagnose the problem rather quickly. (piece of filter stuck in the motor) He performed a complete check on the unit and was really fair with the service call fee. I liked and trusted him so much that I had them modify and install a 4inch filter box. I would highly recommend.
