Get matched with top air conditioning pros in Dundee, IL

"Arrived within the expected hours and provided a thorough inspection, cleaning and servicing of the air conditioning equipment. Serviceperson was clean and courteous and explained the findings in detail. Definitely will continue to use All Temp!"

"This is an extremely professional company. Mike and his team replaced my 20 yr old furnace and A/C system within a matter of hours and exceeded our expectations with the work quality and attention to every little detail understanding that the system will be there for a very long time to come. I've not seen this kind of quality and price for years and not even from the larger HVAC Companies that claim top national status. We were very lucky to find Air temperature pros and highly recommend them."

"The service was excellent. Adrian arrived promptly and was professional throughout the service process. We truly feel that there’s a higher level of air quality in our home following the process. I would highly recommend Mr. Duct if you’re in need of high quality air duct cleaning services. Scheduling was also extremely easy and the office was highly and promptly responsive to all of my questions."

"Very impressed with their heating and air conditioning maintenance. They explained everything clearly, worked efficiently, and left no mess behind. Our home feels fresher after the air duct cleaning. Definitely a trustworthy team you can rely on."

"The air conditioner is working fine."

"He was very good.  I had some company coming from out of town and my air conditioning wasn't working.  He came that day to fix it.  He knows what he is doing.  He gets the job done.  He came within 1/2 hour of my phone call because he was in the area.  He got my air conditioner going right away.  It was really hot that day.  He took care of it right away.  He could have tried to tell me it was the compressor or something, but he didn't.  He was prompt, he did a good job, and he was fair.  He installed a furnace and air conditioner at my mother's house as well.  He did a good job there too.  He was here previously to try and quiet down my air conditioning, but nothing seemed to work too well.  He was really good on the installation, but I thought he was a little high on the repair. "

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"We had five companies come out and look at our house and give us quotes for installing a Spacepak or Unico system in our house. Phoenix gave us the lowest quote (16k less than the highest quote!) and also had the best customer service. Everything was explained to us before, during, and after the installation. The owners seem to have a genuine passion for HVAC, which I wouldn't necessarily expect! Anthony was great with figuring out ways to get air to all the rooms in our 110 year old house with many quirks. Glad to have found this company."
