Get matched with top central a/c service or repairers in Oak Brook, IL

"We purchased a new central air conditioner and a 2-stage furnace. In addition, they needed to update the air circulation to and from the system, which was nicely done. Needed a little tweaking, and one of the owners came out to perform the simple task himself."

"Service was prompt, professional and well done."

"They services 8 GFA's in an apt. bldg. All were dirty and older so extra work needed to be done. they explained all the diagnostics and why they recommended specific repairs. They put them in order of priority so I could budget the work wisely."

"EXCELLENT SERVICE!!!! The technicians were very knowledgeable and timely with the installation. They were also very neat and cleaned up ALL of the debris and took them away. I would highly recommend this company to anyone who is looking to replace their heating or cooling equipment."

"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"I discovered that our A/C unit was not cooling properly.  On 7/5, I contacted All Temp and scheduled a service/ diagnostic appointment for 7/6.  The office staff was friendly and efficient.  Mike B. arrived within the appointment window and promptly inspected the unit.  He discovered that the contactor was bad and replaced it.  After replacing the part, Mike tested the pressure and temperature and confirmed everything was working properly.  Mike took the time to provide some helpful advice for keeping the unit operating at it's peak.  The entire appointment lasted approx. 30 minutes.  I have used All Temp in the past and would recommend them to friends and family.  In my experience, they have been honest, reliable and efficient.  I've never felt that a technician was trying to "sell me something."  A++ Rating.  *Only note is that I was expecting a call prior to technician arrival, but that's no big deal in my book!

"Cody showed up on time. Very polite young technician Appears to know his job well. He examined the indoor part of the system. Verified what initially indicated to his office that Freon is needed. He indicated that vents need to be cleaned before sealant and Freon can be added. Cost was as follows: $96 diagnostics + $203 for 1.5 pound Freon & labor + $60 another 30 minutes labor + $187 sealant (cost $27 on Amazon) = $545. System is working well. This cost is significantly higher than last service provider."
