Our last service technician, Cody Brent was very helpful and capable and got our wiring up to code and explained how it all happened and tripped our breaker. Thank God. However, the last technician that was here to do our overall check up did not even notice or indicate that something could be an issue like the wires that over heated/finally melting and could have burnt my house down. I sincerely like River City's One Hour Air, but I would like a little more consistence in technicians' training or knowledge, so probables can be averted before and not always taken care of after the fact.
