Every AC Problem — One-by-one (Symptoms → Diagnosis → Repair)
Below is a carefully organized table showing typical AC problems, how our technicians diagnose them step-by-step, and the repair actions we take. This is written to help building owners and facility managers understand what to expect.
Note: We explain processes for split systems, ducted/packaged units and common domestic/commercial types. Some faults require replacement parts; where parts are needed we provide clear quotes.
| # | Problem / Symptom | How GossTech Diagnoses (step-by-step) | Typical Repair / Fix Actions |
|---|---|---|---|
| 1 | AC not cooling (running but room not cold) | Inspect thermostat settings; measure supply/return air temps; check air filter and evaporator coil; test compressor operation and refrigerant pressure; inspect condenser fan and outdoor unit airflow. | Clean/replace filters; clean evaporator & condenser coils; repair/replace fan motor; detect and repair refrigerant leaks, evacuate and recharge system with correct refrigerant; repair or replace compressor if failed. |
| 2 | Weak airflow (low air volume from vents) | Check blower fan speed and motor current; inspect ductwork & vents for blockages; check filter and evaporator coil for blockage; examine fan belt (if applicable). | Clean/replace filters; clean coil; unclog ducts/vents; repair/replace blower motor or belt; correct duct sizing or straighten sagging ducts. |
| 3 | Water leaking / condensate overflow | Inspect condensate drain line, trap and pan; check slope of drain; examine for clogged drain or corroded pan; verify condensate pump (if installed). | Clear drain line (mechanical/chemical flush), remove blockages, replace corroded pan, install/repair condensate pump, reseal drain connections. |
| 4 | Frozen evaporator coil / ice formation | Measure suction & liquid line temperatures and pressures; check airflow across coil; inspect refrigerant charge level; check outdoor unit operation. | Restore airflow (clean filters/coils, repair blower), defrost coil; correct refrigerant charge (repair leak if required) and ensure proper thermostat function. |
| 5 | Refrigerant leak (Hissing, oil stains, poor cooling) | Use electronic leak detector or UV dye; inspect joints in refrigerant circuit; pressure test with nitrogen; inspect service valves and brazed joints. | Locate leak, repair (braze/replace component), pressure test, evacuate system to required vacuum, recharge with specified refrigerant and oil, leak-proofing and documentation. |
| 6 | Compressor failure (unit won’t start or trips) | Check electrical supply and contactor; measure compressor winding resistance; check capacitor and relay; inspect for refrigerant floodback or mechanical seizure. | Replace capacitor or contactor if faulty; replace compressor where needed (with proper oil/refrigerant handling); control board replacement if required; verify safe operation and warranty advice. |
| 7 | Unit making abnormal noises (clanking, buzzing, rattling) | Identify noise source: fan, compressor, loose panels, debris, or worn bearings. Vibration isolation and motor mount inspection. | Tighten or replace loose panels/fasteners, replace bearings or fan blades, mount isolation pads, replace failing motors, balance fans. |
| 8 | Foul smell from AC (mold, burning, chemical) | Inspect filters, drain pan and drain line for mold; smell electrical components for burning; check refrigerant for decomposition (rare). | Deep clean and sanitize coils and drain pan, treat with anti-microbial solutions, clear drain line, replace burnt wiring/components and address source of electrical smell. |
| 9 | High energy consumption / inefficient cooling | Perform airflow and temperature split measurements; inspect compressor run cycles; measure electrical current draw and capacitor health; check thermostat calibration. | Tune system for efficiency (clean coils, adjust refrigerant charge, replace weak capacitors), recommend right-size upgrade or zoning, install programmable thermostat. |
| 10 | Thermostat or control issues | Verify thermostat calibration, wiring and batteries; test remote receiver/communication on smart systems; run system through control cycles. | Recalibrate/replace thermostat, repair wiring, update or replace control boards/receivers, pair remotes, and provide user guidance on smart thermostat programming. |
| 11 | Frequent tripping of breakers | Check electrical supply, look for short circuits, measure current draw on compressor and fan; inspect capacitor and motor start components. | Repair wiring faults, replace faulty capacitors, contactors, or motors, upgrade wiring / breaker to correct specification if undersized. |
| 12 | AC blows warm air intermittently | Check compressor cycling (short cycling), refrigerant pressures, thermostat location and sun exposure; inspect sensors and expansion device. | Correct refrigerant charge, replace faulty sensors/thermostats, repair control board, or address cycling causes (overheating, poor airflow). |
| 13 | Remote control not working | Check remote batteries, IR signal, and indoor unit receiver; test manual control at unit; inspect remotes for damage. | Replace remote batteries or remote; repair/replace receiver board if necessary; provide replacement remote codes and pairing. |
| 14 | Ducted system cold/hot spots | Inspect duct balancing, registers, insulation, and leaks; measure static pressure; inspect zoning dampers. | Seal/insulate ducts, rebalance air flows, repair or replace dampers and thermostat zoning controls. |
| 15 | Installation problems (poor siting, vibration, drainage, piping issues) | Inspect pipe runs, oil traps, mounting, refrigerant line insulation and electrical termination; verify manufacturer clearances. | Re-route piping, add vibration isolation, correct slope and supports, re-braid joints to code, re-commission system to manufacturer specs. |
