"I was told my serviceman would arrive between 10am-12pm. He called me at 9:30 that he would arrive in about half an hour & he did, right at 10am. I had a list of specifics to be checked because I bought the service discounted through Angie's list & I asked how he did each thing on the list as he did it & he explained in detail each thing he was doing. He found nothing wrong with my furnace & I told him I was pleased with that because I've had others make up things wrong that aren't just to make money & I am hiring someone because I can't tell when things are wrong & his company did not do that. He asked if there were any questions that he had not yet answered. He also told me how old my furnace was because it was in my house when I moved in & I didn't know. He was very informative, polite, prompt & I am much more at ease that I won't have a heating problem when I need my furnace most."

"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"After Freedom did my tune up for the furnace on the 1st floor it strangely no longer blew warm air; I decided to replace it at that point because it was no longer under warranty. I decided to go with a different well-known Chicago Furnace/AC installer that I had dealt with before. It was later discovered by the furnace installer that the thermostat merely needed replacing - so an unnecessary furnace replacement was just done just to prevent future expense of furnace breakdowns. Last summer I had new A/C units installed on the 2nd and 3rd floors. My 2nd floor tenant just recently complained that there was water leaking through the ceiling of their furnace closet. I remembered that I saw the Freedom tech had disconnected the A/C PVC drain pipe for some reason while he was doing the furnace tune up for the 3rd floor but I assumed he would put it back together and re-caulk it. Since it has been hot my tenants have been running their A/C (beginning of June) which creates more condensation that drains into the PVC pipe then the kitchen drain. The drains were both rodded after the new A/C was installed so that was definitely not the issue. The ceiling above the 2nd floor furnace (and under the 3rd floor furnace) is now ruined - the plaster fell down and the joists got wet from the leak that was not immediately unnoticed because A/C units have just been turned since the beginning of June. Upon inspecting the PVC drain pipe, I discovered all of the caulk had been cut from around the pipe where it connects to the galvanized drain and not replaced. After some silicone application by myself and waiting for it to cure, the leak has stopped. I wonder what the reason would be to disconnect the A/C drain pipe if the furnace is being serviced? When the new A/C units were installed for 2nd/3rd floors and the units ran the entire summer, nobody had complained about any leaks so I do not believe that is when the problem first started. So now I have to deal with a damaged ceiling that a furnace is sitting on top of (there is a concrete block under the 3rd floor furnace) due to contractor error. I really don't appreciate my property being damaged by a careless contractor nor the headaches that I now have to deal with to fix this problem. The old saying goes, "sometimes you get what you pay for" - I am learning that the cheapest deal is not always the best one out there."
