The prompt only allowed me to choose one option. But the whole team was professional, helpful, on time, and provided me with all the information I needed on the quality products that were installed.

I’ve been with Guthrie & Sons since 2008. They installed my new unit and have serviced it twice a year ever since. Something has changed and not for the better. Most notable in communication. After a service visit I received several quotes for further work, mind you no call made during the visit to notify me of these items. New quotes also include a $95 visit fee! If I’m already paying for the initial visit why would you leave without speaking to me if more work was recommended? I called the number on the email that specifically said “if you have questions”. Needless to say the person who answered “Amy” couldn’t provide one single thing of information regarding my visit and I have to speak to the technician. She was politely dismissive and just kept referring me to the technician. This isn’t the level of service I’ve had in the past and not sure I can stay if this is the new standard.

They offered a very competitive price for a much higher SEER unit and they were efficient, clean and informative completing the removal and install of the new unit in one day. I am also very happy with the Bosh unit they recommended and installed.
