Verified record
Complete Heating & Air Conditioning Systems is a Sterling HVAC contractor that Angi lists with 12 years of experience and services including central air-conditioning installation and repair and commercial heat-pump work. Procore also lists heating, ventilating and air-conditioning as its trade and says it serves the Sterling area. The only dated customer account currently available is a May 2019 Angi review, which calls the company a great contractor and recommends it; it does not describe a particular installation, repair, or outcome. Angi shows a 4.5-star average from one rating, so that score is a very small sample rather than a deep track record. Before booking, confirm the exact scope and current availability, especially if you need plumbing as well as HVAC: Angi mentions plumbing professionals, but the specific service list and Procore profile are centered on HVAC. This is a reasonable lead for a Sterling-area heating or cooling inquiry, with references and a written estimate worth requesting given the dated, limited review history.
Great contractor and we would recommend to anyone.
