Reviews
What customers say
Reviewers praise technicians for clear explanations and recommendations they did not feel pressured to accept. A customer describes a spring HVAC check that uncovered a condenser leak, explained with photos, followed by repairs and system start-up. Another customer says system changes were followed by an odor they had not been warned about; Casteel told them it was normal and would last, and they felt the charges were high.
