Advanced Diagnostics Heating and Air LLC

Advanced Diagnostics Heating and Air LLC I’m Frederick Evans, owner and licensed HVAC technician. I specialize in accurate diagnostics, honest recommendations, and efficient repairs for residential and light commercial systems. What sets my business apart is simple: Most companies guess and replace parts — I diagnose the system correctly the first time. That saves you time, money, and repeat issues. I’ve worked on everything from RTUs and split systems to mini-splits and complex diagnostics, and I approach every job with a technician’s mindset — not a salesman’s. Customers hire me because: • I find the root problem, not just the symptom • I don’t upsell unnecessary work • I communicate clearly so you understand what’s going on • I treat every system like it’s my own investment Whether it’s a breakdown, poor performance, or a second opinion, my goal is to give you clear answers and reliable solutions you can trust.
