Heating and Cooling HVAC Repair Across Bell Gardens

Here is how each system tends to act up.

• The long season here

  Central air and package units

  No cold air, a unit that "keeps cycling", ice on the indoor coil or water under the AC. The fix is often a small part: a "run capacitor" when the outdoor unit hums and the compressor never starts, or a cleared "condensate drain line" when water shows up indoors.

• Gas furnaces

  Burners that light and then cut out, or vents blowing cold. Grime on the "flame sensor" is one of the most frequent reasons for no heat. A cracked "heat exchanger" is another matter: it can leak carbon monoxide and usually means replacing the furnace.

• Wall heaters

  The gas or electric "wall furnace" built into a wall, a standard heater in older houses. We get the ones running that will not light, will not stay on or barely warm the room.

• Heat pumps

  One outdoor unit that both heats and cools. Stuck in one mode, the "reversing valve" is the usual suspect; frost that never clears points to the "defrost board".

• Ductless mini-splits

  Wall-mounted heads for rooms and add-ons that have no ductwork, each fed by a small outdoor unit. Weak air, dripping heads and a unit that will not answer the remote.

HVAC repair

Try these two, in this order.

1. Thermostat mode

   For cooling, set it to cool and drop the setpoint below what the room reads now. For heat, set it to heat and raise the setpoint above it. A wrong mode looks exactly like a broken system.

2. Air filter

   Slide it out and hold it to the light. Filters are due every 1 to 3 months, and a choked one cuts the airflow until the "evaporator coil" can ice over.

Both fine and still no comfort? At that point it needs a technician, so give us a call.
