HVAC terms explained
- Static pressure: a measure of airflow resistance in the ducts
- Contactor: the switch that sends power to the outdoor unit
- Capacitor: stores charge to start and run the compressor and fan motors
- Evaporator coil: the indoor coil where refrigerant absorbs heat from the air
- EPA Section 608: the certification required to handle refrigerants
- Superheat and subcooling: readings that show whether the refrigerant charge is correct
- Condenser coil: the outdoor coil where heat is released
- Condensate drain: the line that carries moisture out of the house
Myths and facts
- Myth: maintenance is optional. Fact: dirty coils and weak capacitors cause many summer failures.
- Myth: a bigger AC is always better. Fact: oversizing causes short cycling and humidity problems.
- Myth: set the thermostat very low to cool faster. Fact: the AC cools at a steady rate and just runs longer.
- Myth: refrigerant is used up. Fact: low refrigerant means a leak.
- Myth: closing vents saves energy. Fact: it raises duct pressure and can cause leaks and noise.
A checklist for this week
- Clear the outdoor unit of debris
- Inspect the drain line outlet and the area around the air handler for water
- Book a tune-up if it has been more than a year
- Test the thermostat and schedule
- Write down any noises or smells
- Check supply and return registers
How an air conditioning repair visit works, step by step
A diagnostic visit should follow a repeatable order so the technician finds the cause, not just the symptom. Knowing the order helps you tell a thorough visit from a part swap.
- Interview: what you noticed, when it started, how the system sounds and what you have already tried.
- Visual check: thermostat settings, filter, supply and return registers, the air handler, the condensate line and the outdoor unit.
- Electrical tests: breaker and disconnect, capacitor microfarad rating, contactor contacts, motor amperage and control voltage.
- Airflow and temperature: the temperature drop across the evaporator coil and, where needed, static pressure in the ductwork.
- Refrigerant checks: pressures, superheat and subcooling, and a leak search if the charge is low.
- A written finding: the cause, the repair options and what each one would fix, before any part is replaced.
What shapes the written scope
Two AC calls that sound alike can be very different jobs. The written scope should say what the technician found and which of these factors applied.
Have the provider show the diagnostic and the repair as separate items, and list any parts, labor or follow-up that are left out.
- Whether the ductwork, return air or thermostat contributes to the problem
- The age, tonnage and refrigerant type of the system
- Access to the air handler in the attic or closet and to the outdoor unit
- Whether the fault is an electrical part, an airflow problem, a refrigerant leak or a drainage problem
- Warranty status of the parts and whether the equipment is registered with the manufacturer
Safety and rules to know
Three hazards share one machine in an air conditioner: high-voltage electricity, pressurized refrigerant and moving parts. Opening electrical panels, bridging contactors and adding refrigerant are not jobs for homeowners, and capacitors can keep a charge after the power is off.
In the United States, anyone who buys or handles refrigerant must be certified under EPA Section 608, and refrigerant must be recovered and not vented. Ask the technician for their certification and check the contractor's licence with Tennessee Board for Licensing Contractors (HVAC classifications).
What makes air conditioning repair different in Memphis
Hot, humid Mid-South summers with heat indexes often above 100 degrees; winters can bring ice storms. Humidity drives condensate drain clogs, sweating ducts, and mold in air handlers.
Memphis Light, Gas and Water (MLGW) is the local utility. Older homes in Midtown, Cooper-Young, Binghampton, and Whitehaven; newer homes in Cordova, Collierville, Germantown, and Bartlett. The diagnosis and the equipment recommendation for your address can both be shaped by these local conditions, so ask the technician how.
