"Trinity HVAC got in touch with me right away and their communication was excellent, letting me know when someone could come out and they showed up as scheduled. Chris inspected the unit inside and outside to assess the situation then thoroughly explained the problem before doing the work. He provided a follow-up email with the invoice showing the detailed items that were repaired and photos."
