I paid them $2,200 for a new propane HW heater, and service check on the A/C and Heater. They did…read morenot tell me they would charge me for travel time from Peru. The tech did not tell me that the foam on the A/C was totally rotted thru, he removed the vent shield from the side of the heater making it less efficient. He did not notice that a coupling was the wrong type and could have easily leaked. He also didn't have the right shut off fitting and told me to keep the one he did have at a 45' angle, not 90' or 0' as is standard in shutoffs. I would never use them again.

If anyone is thinking of having CRS Mechanical install a Daikin mini-split system in your house or…read morebusiness for air conditioning, FORGET IT. Unless you want a poorly-installed system that keeps breaking down and leaves you without cool air on the hottest days of summer, don't use CRS Mechanical. My Daikin is 5 years old and I have had them out every year since it was installed. The Daikin was replacing an old Sanyo AC that ran for 20 years without needing repair. CRS has come out multiple times, charging me hundreds of dollars for each visit, but my unit STILL is not functioning properly. CRS has not followed up on commitments to complete the promised work (e.g., coming back to confirm leaks, etc.) CRS was a BAD choice! (I live in Joliet, but I'm posting on my son's Yelp account.)

Also, we have two HVAC systems in our home and both appear to be undersized. I will be getting an estimate to upgrade both systems, as well. Roger is very friendly and does great work. He's responsive and very easy to deal with. They were referred to me by a friend, who trusts them as much as I now do. I had a horrible experience, with a different HVAC contractor, about 12 years ago and it's nice to now have a contractor that I can trust. Having trust in a contractor is important, and they've earned my trust. I highly recommend them!

Once that was done he was able to install the central A/C in less than two weeks. Everyone I spoke with about the A/C unit said that the price was amazing. I'm pretty sure our neighbor had him update her central A/C too. Highly recommended!

His first question was why did I think I need a new one?. My reply was because the storm took it out and it must be damaged. " I can fix it if you wish, it is your choice" Within 10 minutes the A/C was running and he was giving me hints on how to take care of it. Most would have taken my word for it and begin giving me a price for a new one. Not Frank. His honesty saved me $3000 dollars or more. I will not be forgetting his honesty or his professionalism. THANK YOU FRANK. Roy Cavell.
