Collins installed our geothermal system 14 months ago. Have had numerous parts break and replaced already. Called them today to come check out ac not working at all. Was told our labor warranty expired and we would have to pay $109/hr on the spot…. called another company who responded quicker so appt with Collins was cancelled. He went in the crawl space and came out and said we have five year labor warranty and two more parts needed replacing. So glad we called Artec Air and did not use Collins! Sounds like they don’t care about keeping track and honoring warranties.
