Christian was very polite and professional and explained everything to me. Thank you very much!
From the time I called to schedule the appointment to the time the technician left, only 3 hours passed. Quick, timely service. Carl was very kind and professional and fixed our leaky AC.
Martin was on time if not a little early. He had to work on our AC unit in the attic no easy task this time of year Iโ€™m sure. He was professional, kind and courteous. AC is working again. Thank you

Haller was able to get a service technician out to us quickly despite it being new years eve. Their technician Shane was very communicative and went above and beyond to thoroughly diagnose and resolve the issue, as well as provide some advice on keeping our system in good shape and wiring efficiently.

Detailed reports
We were with Goodco since 2010, stayed with them through the merger and have had good experiences with them. The Geothermal system served us well for 16 years but we thought it was time to upgrade.
