Thank you, Curtis (and Dale’s) for troubleshooting my Dale’s-installed HVAC system! Curtis responded the day I called! Upon arrival, Curtis asked timely questions, then expertly and quickly found the problem (leaking refrigerant). He then proceeded to add dye to the system to aid in determining the faulty part(s). I appreciate his congeniality and professionalism thru the heat (AND the rain!) Curtis is keeper!
