I had an extremely poor and exhausting experience with Cullins One Hour Heating & Air Conditioning.From November 8, 2025 through late December 2025, the company failed to properly diagnose or repair the heating system in my home. Over this period, five different technicians visited my house, and each one gave a different diagnosis and a different price. None of them were able to fix the problem.According to their own service records:• One technician recommended replacing a low-pressure switch• Another disagreed and blamed the TXV• A later technician determined that both prior diagnoses were incorrect and concluded that the evaporator coil and lineset were contaminated and had failed, requiring full replacement.Because of these repeated misdiagnoses and delays, my heating system was forced to run in emergency mode for over two months, during some of the coldest weather of the year (down to about 3°F / -16°C). My family lived in a cold home throughout this period, and we were left with over $1,000 in additional electric bills.This was not a minor inconvenience — it was a prolonged failure to resolve an essential home service during winter. The lack of consistency, accountability, and professional competence was shocking for a company that advertises itself as reliable and customer-focused.Based on my experience, I cannot recommend this company to anyone who values accurate diagnostics, transparency, or timely service.
