Get matched with top central a/c installers in Round Lake, IL

"Great job completed by the Mr. Duct technicians Kirkland and Emmanuel. Will hire again next year!"

"The gas company had to inspect the lines in my house. They looked at the Heater in the basement which is in a Utility room. AllTemp had installed the 90% HE heater and AC about a year ago. The gas company said the intake should run outside or to a more open part of the basement. 
The old heater was also vented incorrectly. I had no idea that both the old and new heaters did not have proper intake venting. Why should I? It is not my line of work. I believe AllTemp should have seem the problem when giving me the quote last year and corrected the problem when they installed the new system. AllTemp wants to charge me to do something that should have been done already and included in the initial installation.
I am trying to write a fair review. Their pricing was good for the heater and ac, they installed it quickly without making a mess, the sales person was professional. They install quality systems and do not try to sell you things you don't need. Example the sales person said I did not need a new filter box, all other vendors I got quotes from tried to push a new filtration system on me. 
So if you are looking at the sales process, installation, and price of the new AC and Heater they did a good job with the exception of not fixing the intake venting problem.
I just would like them to fix the intake vent situation. It is something they should have included with the installation.

***UPDATE****
All Temp agreed to fix the venting issue for no charge. Their technician came up with a clever venting solution and came back on 10/16 to implement it.  Took him 30 min and he was done.

Thanks All Temp for making this right."

"I honestly don't have enough positive things to say about these guys. They were on time, every day. Their team was professional and courteous, going above and beyond. Every day when they left my home, everything was put back the way it was when they got there. I hardly even knew a MAJOR HVAC installation was happening when they weren't around. You're honestly stupid if you don't hire these guys!"

"Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company."

"I hired Full Efficiency to do the spring tune up for our central AC.

We plan to have him back in the fall to prepare our furnace for the cold weather months!"
