I was impressed by this company until I got the bill. The service person was helpful but the first time he came out he was unable to fix the part and it had to be ordered. Then he can back and replaced the part once it came in. We were charged 1.25hr each time he came out. He was not here that long either time but because they charge starting when they leave the last job. Driving all the way across town take 25 min and I had to paid for that. Not impressed.

On the hottest day of the year I turned my A/C on, and wouldn't you know it, it was not working. I phoned CJ Hansen at 8:00 a.m. expecting to have to schedule a service appointment days away, but they had a service man (Jake) here by 9:15 a.m.! He had the problem fixed by 9:45. Now THAT is fantastic service! Jake and CJ Hansen have my deepest appreciation and highest recommendation!

Technician was very professional, and quick at determining the issue. Also, Dan was friendly explaining everything he was doing along with helpful tips for accessing online help sites. Also, Kelly that is the one who takes calls, delivers exceptional customer service over the telephone. I highly recommend this company! Thank you Hanson's for fixing the issue with my heater so quickly!
