Great experience with Dave. Knowledgeable about the geo systems. He will be continuing my yearly maintenance and service calls..
We have used Hartzell's several times for problems with our heat & air. Dave always arrives promptly & solves the issues for us.
Was very informative and knowledgable. Had my unit fixed and up and running in about 30 minutes. I will be calling him again for all my a/c repairs.
Give 5 stars
We called Dave out to get a second opinion and he fixed our problem! So happy to have the leaking fixed. Thank you so much! Called him and he came same day. Very great service!
