 Trustindex verifies that the original source of the review is Google. HHvac Technician was extremely knowledgable (third generation HVAC professional). Solved issue with leaking air handler in attic, but then went above & beyond by diagnosing issues with 20 year old, 3-ton A/C. Prior service company had over charged refrigerant head pressure in a misguided attempt to resolve inadequate cooling. HHvac corrected the constant high pressure trip problem and cleaned the condenser coils; we now have a perfectly operational system again!
