Contact USA HVAC Pros
When HVAC problems arise, calling USA HVAC Pros starts the repair process. Technicians ask about specific issues like a heat pump failing to switch modes or ducts leaking conditioned air. They arrive ready to inspect components such as the blower motor or reversing valve.
Details to Have Ready
- Record the model number and serial number from the data plate on both the indoor air handler and outdoor condenser.
- Note any error codes on the thermostat display along with the exact times they appear during operation.
- Measure and record supply and return air temperatures at the vents while the system runs in heating or cooling mode.
- List recent filter changes, capacitor replacements, or other maintenance performed on the equipment in the past year.
Precautions to Follow Until Arrival
- If a burning plastic smell comes from the furnace, shut off power at the breaker and stop running the system to avoid further damage to wiring.
- When water collects around the indoor evaporator coil, turn off the main disconnect switch to the air conditioner to reduce shock risk near electrical parts.
- For a gas furnace that fails to ignite after repeated tries, close the gas supply valve at the meter line and ventilate the space without flipping light switches.
What Happens After the Call
Technicians review the symptoms and model details provided to select appropriate gauges and replacement components such as contactors or TXV valves. On site they measure refrigerant pressures, check amp draws on the compressor, and test airflow across the heat exchanger before any adjustments or part swaps.
