Scott came by today to perform routine maintenance on our air conditioners. He discovered one of the capacitors to be failing & was able to replace it quickly & efficiently. Now I can get through the summer without worries. Thanks Scott!

Hello, just a little note to tell you how great our Technicians were today.Ivan and Troy showed up a little ahead of schedule, met with us, checked out the work areas and got right to work. And they did a fantastic job! I thought I was going to hear all kinds of banging and all kinds of noise but instead it was just a little bit of noise and the cool sound of Ivan whistling... reminded me of my Dad, he always whistled to, it was great.Troy was also quietly working outside.Upon completion of the work Troy and Ivan showed us their work and how the new thermostat worked.They did a great job with the installation, very professional work! I've seen a few air conditioning/furnace installations over the years when building homes with my dad and cousin...and these two technicians (Ivan and Troy) are obviously very good at what they do, and very good with the customer service experience they exhibited to us!!And personally I think they both definitely deserve a raise!!! And no, they didn't ask me to say this, LOL. It's obvious they're humble guys that would never ask for something like this, but they definitely deserve a raise...at minimum some fantastic kudos to some great Hobiaca Technicians!Kudos to Ivan and Troy for a job very well done!Thank you,Jack and Jackie Guzman11/11/2021
