"Installation went well. I chose by "YELP" referrals . I feel I over paid out of sheer desperation. A/C was shot . The salesman was a bit cocky, arrogant. I needed it & I got it fast. Salesman claims of an $ 1800. rebate were B.S.. I was apparently taken off the final price. Very SLY !!! Still they are highly recommended.on YELP................................... P.S. Installer was a Pro . Thus I feel secure in that area."

"Very well. The technician seemed well trained. He went through all vents and registers meticulously. Cleaned the furnace base unit thoroughly. Showed all the filters which needed to be cleaned, dried and re-installed."

"My furnace was installed by someone else that did a very poor job. I could not replace the filter without smashing it and smashing the new one to put in. Ridiculous! I had All Temp come out and they were able to do a quick fix so I didn't have to struggle with it anymore. He was on time, pleasant. He even put up with my dog wanting to say hello to him, Definitely would hire again!"

"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"Rick, CR Mechanicals, is OUTSTANDING and AWESOME! I needed a dryer vent connected to the outside wall replaced with a new dryer vent so that my new Samsung gas dryer could be installed. Best Buy would not install it to existing dryer vent and said I needed to have it replaced. It was a tricky and complicated situation. Rick came yesterday afternoon, did an excellent job and then connected my new gas dryer. Rick was very concerned about my needs and safety. Rick provided an exact cost estimate and did the work as promised. I cannot thank him enough since I had been without a working dryer for over 2 weeks and making trips to the laundromat. This morning we are having a huge blizzard with over 12 inches of snow and are homebound now. Rick is very professional, thorough, knowledgeable, honest and hardworking. He even contacted me this morning to check if everything was okay. Do not even hesitate to call Rick with your homeowner needs! I highly recommend CR Mechanicals. If there were 10 stars, I would have selected that for Rick and CR Mechanicals."
