Would love to give this company 10 stars…read more We have our unit serviced twice a year but of course during the hottest days in August 2024 that's when we experienced problems. 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

I will definitely use Koppei's for my future heating and cooling system needs. Thank you.
