HVAC TIP OF THE DAY “Airflow Before Refrigerant — Always.” Before you ever touch gauges or add refrigerant, verify airflow: Clean filter Clean evap coil Proper blower speed Correct static pressure Low airflow will fake low refrigerant symptoms, leading to: Overcharging Compressor overheating Premature system failure Voidable warranty issues ✅ Diagnosis Rule: If airflow isn’t proven first, the refrigerant diagnosis is invalid.

Most HVAC techs lose the homeowner in the first 60 seconds because: ❌ They don’t open the air handler❌ They don’t show anything❌ They don’t explain anything❌ They hide behind “trust me”❌ They guess❌ They skip steps TA-14 fixes that with: ✔ The Inside 7 Minutes✔ Transparency✔ Showing every reading✔ Teaching the homeowner✔ Proving every claim✔ Opening the air handler FIRST This is what separates a TA-14 Journeyman from a “parts changer.” More tips coming.

Most technicians think refrigerant diagnostics is where a call begins. But here’s the truth: Airflow is the first domino — if it’s wrong, every reading after it lies. Here’s what to check before anything else: ✔ Return air size Minimum 144 square inches per ton ✔ Blower strength A weak blower = false temperature split ✔ Filter condition A clogged filter = refrigerant readings that lie ✔ Duct restrictions Kinks, crushed sections, or closed dampers destroy accuracy When airflow is off: - Suction looks low - Superheat looks wrong - Subcooling lies - Pressures mimic leaks Fix airflow FIRST. Diagnose SECOND. Transparent Air 14.

Most HVAC breakdowns don’t happen because the system “just failed.” They happen because techs jump straight to refrigerant before checking the two things that matter most: ✔ Electrical Health ✔ Airflow Performance Here’s the rule elite technicians follow: Never put gauges on a system until you know the electrical and airflow are perfect. Why? Because: - Weak capacitors give false refrigerant readings - Undersized return air makes a system look low - Failing blower motors distort superheat & subcool - Bad wiring causes pressure symptoms that mimic leaks - Poor airflow ruins refrigerant balance before you even touch your gauges Refrigerant is the LAST step — never the first. Elite techs follow the right sequence: 1️⃣ Fan switch to “On” → Confirm power2️⃣ Check return air → 144 sq in per ton3️⃣ Verify electrical → capacitors, wiring, connections4️⃣ THEN check refrigerant Do it in this order, and you’ll: - Reduce callbacks - Diagnose faster - Look like an expert - Earn homeowner trust - Make more money - Protect compressors and motors before they fail Do it the right way.
