Reviews of local pros in Addison, Illinois

Sam did an awesome job with the maintenance of my HVAC system. I will recommend to use his services again.

Our heater died. I called for an appt in the evening. Four Seasons came out the following morning made the assessment that we needed a new furnace and we’re back a few hours later to install it. It took many hours, but the service was great and we have heat again!

Nothing special, but gets the job done and is required to keep up with warranty. Tech did not clean up well after service was done- left insulation all over floor below attic entry.

UPDATED, 10/3/2025: I was contacted daily by Four Seasons after posting this review. When I had time to return their calls, texts & e-mails a few days later, I was asked what they could do to have me change my review online? I shared the reasoning behind my review (which had been requested by them with more than one text- I didn't seek out posting anything online). I also shared additional concerns from the most recent experience that I hadn't included in this review. I was offered 'up to $100 credit' for future services if I would consider editing what I posted.

Four Seasons is the #1 choice in home heating & air!!! My service was professional and restored my home to COLD AIR!!! They leave a contact label because they stand behind their work!!! Four Seasons is a clear choice.

The service man call to let me know he was on his way. He did an excellent job. Very clean and tidy. Highly recommend 4 Seasons

I phoned and made appointment for an electrical issue. It was a few days wait, not bad. They were to come on Saturday between 1 and 6 pm. No one showed up. They had my contact info correct as I was texted. I spoke with more than one person and was told the driver was still coming. I finally called at 8 pm at night and I was told someone would call me back to reschedule asap. It’s now Monday afternoon and I have heard nothing. Glad this was not an emergency. I will NOT be recommending Four Seasons.

Juan and his crew did a fantastic job installing the furnace and AC on a very cold day. They are very professional, courteous and hardworking. It was a very large job and took them more than 10 hours to complete. They made sure it is done properly no matter how long it took.

Great technician. Showed and explained everything that he was doing. He took the time to explain that I needed to address 2 issues to prevent future problems. I appreciated the additional assistance in pricing of the additional repairs.

Great employee who went above and beyond in taking care of HVAC system. What a wonderful man who was interested in my needs. Quite the gentleman. He's quite an asset to your organization.

Tim Stone was great! He took his time to do the job right. He really cares about the customer. We would absolutely recommend Tim for any job.

Four Seasons did a great job installing a new HVAC system in our home. The sales guy, Nate gave us a great deal, was upfront with everything and is very knowledgeable about all of their products. We opted for a heat pump over a conventional AC unit and Nate got us all the available rebates out there which helped to greatly reduce the cost. We purchased a Lennox furnace (2 stage with variable speed drive). We also opted for the UV air cleaner and received a free humidifier and a Lennox digital do everything thermostat . The installers did a great job, were very respectful and cleaned up everything when finished. Couldn't have asked for a better crew. We obtained several quotes and no other company could match their parts and labor warranties and we received 5 years of free check-ups/service visits in the spring and fall.

This is a great company. Adam was my tech and did a great job. Polite, put his shoe covers on and seemed informative. Offered us a discount for duct cleaning which we will probably take advantage of. Only negative is they don't give you a small 2 or 3 hour time slot for their tech visit. They tell you between 9am and 4pm, so you pretty much have to give up your whole day.

Had my HVAC system installed. Both furnace and A/C.
Installers did an excellent job and explained everything to me in detail. They worked diligently and were polite and welcomed all my questions, which were answered so I could understand.
They cleaned up very well and left us without worry of any problems unforseen.
The next day your vent system cleaner was here and was excellent as well. I would certainly recommend your service people and have great confidence in them.
The only drawback was i was hoping pricing was a little bit less but I understand the cost of modern materials so not upset at all. Now let's see how well your warrantee holds up.

The salesman was extremely nice and informative. He told me I would not get a better price and he was right. The installers were really great. Also, I really enjoyed this experience. Will definitely tell others about you.

Excellent job done, the sales team was very supportive And the technician was best ! Did very clean work , was very detailed oriented and made sure the work is clean and before leaving did couple rounds of testing himself. The furnace replacement job was supposed to be in 2-3 hours however they stayed more than 7 hour till 10 pm to complete the work and also replace the AC unit for me ! Much appreciated 👍

They talked me into a new HVAC system after doing a duct cleaning. My office was still freezing or boiling hot which I mentioned at every tune up to shrugs over the past year plus. My paint started peeling off the walls due to the cold. We put an endoscope down the vent to see they missed children’s books that had been put down the vent by the last person who lived here. They sent someone out and said they would put in a claim. Tech who did nothing and said we’d get a call. No call after a week. Tech had told them everything was fine and no claim had ever been filed. Put in the claim finally and waited with no call. Called again and was told they’d call me back in 72 hours. They call back and I was told they wouldn’t do anything about the items in the vent but they’d give me 3 years of free maintenance and send me an email saying that if we decided to fix it on our own that it wouldn’t violate our warranty. I also scheduled a cleaning for the following Monday (today). No one ever showed. Never received the promised email. Call and they never scheduled anything. I then speak to 3 different people, an AI, and left a voicemail to be told they had to speak to someone else to send me the email and they promise, promise (pinky swear) someone will show up on Friday. Absolutely furious. Still no email after speaking with at least 13 people so far. We spent 20k with them at least and I doubt now we even needed the new system.

EDIT: they called me back to basically just make me tell them the whole thing again and promise, again, to get me the paperwork I requested so a waste of time. Do not use these people. They will not show up and will not stand behind their work or acknowledge that they dropped the ball in any way. They do not care. Notice how all they talk about in their response it is the duct cleaning and not that fact that they do no show up to appointments, lie about wha they’re sending you, and drop the ball at every turn. Why didn’t you show up? Why do I need to talk to 15 people to get anything 25% solved?

For the price of the furnace , you would think they were sent in two technicians to take care of a job and the price that I paid they only sent in one guy and it took eight hours. The technician was great in his overall performance and cleanup was great it just the service of 4 Seasons only sending in one technician to do the install. That was very bad And unacceptable nor professionally in my perspective

My experience with Don Walter(?) was EXCEPTIONALLY FANTASTIC! I believe he went above and beyond! He was very knowledgeable and personable. He noticed a gas smell when entering my home. He encouraged me to call Peoples Gas. Kudos to Peoples Gas, too. They sent someone rather quickly. They determined a gas leak to my dryer - all because of his expertise and knowledge of his work. Although today was a somewhat stressful day for me, I received exemplary service from Dan.

Furnace was completely out of order and another company told me I had to replace. Addison provided my second opinion and was able to diagnose the real issue almost immediately - then inspected my whole unit anyways to be certain. Great experience and saved me thousands of dollars, would recommend!

I am very happy with my service, Marco was very professional and knowledgeable. Replaced my furnace with no issues, and even cleaned up after himself better then I expected. My old one went out due to age and December is the wrong month around here to not have heat. I got priced for a new one and it was installed in a few hours. Wonderful job! Would definitely recommend them in the future.

The two young gentlemen were on time and great with communication. We were probably their grandparents age. They were so patient with our technology questions. They put covers on their shoes and picked everything up before they left. They had a final walkthrough to answer any remaining questions. All working great!

Update, they reached out and said they would refund the date he came out for service.
The “one-year no breakdown guarantee” seems to mean very little. I had preventative maintenance done last week and was told everything looked good. This week, my furnace stopped working.

A technician came out, checked it, replaced the filter (with my filter — the previous one was only three weeks old), reset the rollout switch, and charged me $300. There was no repair made and no explanation for why the furnace was shutting off on safety. When I questioned the $214 portion of the charge since nothing was repaired and no root cause was identified, I was told, “It wasn’t running when I got here, but it’s running now.”

I called customer service to ask what the point of the breakdown guarantee was. They agreed I should not have been charged the $85 fee and said they would credit a portion of my bill because they believe in good customer service.

A couple of hours later, my furnace would not shut off. I called again and was told they could send a senior technician and waive the $85 fee. At that point, I decided I no longer wanted to continue service.

It turns out the technician left a jumper on my furnace, which is why it was running continuously. Leaving a jumper in place can cause additional long-term issues. So in the end, I paid $300 for a reset, no diagnosis, and a mistake that might have caused further damage.

Customer service was polite, but between the unclear guarantee, charges without clear repair, and the technician error, this was not a good experience. I will not be using this company again.
