Said he was going to talk to someone else about it and have never heard one word from Tim. Won't return phone calls or text. Not any way to do buisness. Your dad did not do buisness like that. No website to leave a review for him so I'm doing it here. I know they are the same family.

Outside temperatures almost triple digits with heat index well past 100-105. On Tuesday night at 9:30 pm we get a message from our smart thermostat that instead of keeping the house at 73 degrees it was now 78 and we needed to contact Koppeis. I called at 8 o'clock on Wednesday morning for a service call. Due to the extreme heat wave the best I could get was afternoon Friday. Well, I took the appointment. Received a call Wednesday afternoon and we were moved up to Thursday early afternoon. WOW... the technician got here about 1:15, same guy we had for our routine checkup in the spring so he was knowledgeable with our setup. He checked the outside unit; capacitor out; under warrenty; switched it out; checked out rest of the unit and was gone about 2:05. Love these guys. The temperature in the house had gotten up to 85 before the service call. Now at 4:15 we are at 78 and still dropping. Nice. I would whole heartily recommend Koppeis for any of your heating and/or COOLING needs. GL Rawson
