Chicago Heating And Air Conditioning

Their technicians don't know how to properly install a furnace nor do they know how to accurately determine what size furnace should be installed based on the square footage of a building. I had a 20 year old furnace fail and hired this company to install a new one. After the new furnace was installed and issues were still present I was told the airflow wasn't adequate enough and I would need to redo the ventilation system in the home. However, before I agreed to something like that I hired 3 other companies to get their opinion and every one of the companies said it's not a ventilation issue. The furnace was oversized for the unit and shouldn't have been installed. Thankfully, one of those companies was able to readjust the furnace to reduce it's output so it would run without any issues, but said I should have Union Heating and Air Conditioning come back and install a correctly sized furnace because the adjustments that were made will burnout the furnace and it won't last long. I explained this to Union Heating and they claimed every company was wrong and that the furnace they installed in properly sized for the unit. I even sent one of the reports from the other companies to one of their HVAC supervisors. He never directly refuted the report and said I should contact the manufacture directly regarding if it'll burnout. When I contacted the manufacture I got the typical canned response that wasn't really helpful in terms of confirming if the furnace will burnout. But the manufacture did say a load calculation should be done in order to determine which size furnace should be installed, which this company did not do based on the information I received from the other companies. When I told Union's HVAC supervisor this he said he'd contact the manufacture directly and get back to me to prove everything is legit. Months later I have yet to hear back from him or anyone from the company. Unfortunately, today I had an issue with the furnace and hired a technician from another company come service it. He was able to troubleshoot it fairly easily to get it working again, but told me the furnace is oversized for the unit and based on the settings it's on he doesn't think it'll last longer than 5 years. So now 4 companies disagree with Union Heating's assessment of things and I'm now saving up because I'm anticipating having to replace a brand new furnace in 5 years because this company didn't want to come back and install a properly sized one. Additionally, when the company first tried to charge my card for the install they entered the card information wrong somehow. Long story short after their incorrect attempt their company got blocked from processing my card by their card processing network or my bank (no one could figure it out). So I had to cancel my card and reorder a new one in order to pay them.
