Correspondingly, where is the 24v transformer on HVAC?

Most of the time the transformer is located inside the furnace, although sometimes (about 10%) it is located inside the outdoor AC unit. The transformer produces the 24 volts which goes up to your thermostat then out to your air conditioning unit when the thermostat calls for cooling.

Likewise, how do you test a HVAC 24v transformer? Use a multimeter to test your transformer. Switch the multimeter to "ohms" and insert the red and black test leads into the meter. The red lead goes into the slot that reads "ohms" and the black lead goes into the common opening. Touch the two leads together.

what happens when a transformer goes bad?

Like all electrical devices faults also happen in the transformers which cause failures [1]. One failure can cause many problems. A simple fault at the distributing end can cause black-out of power to the whole area. This increases the risk of fire and explosions due to failures.

How much does it cost to replace a furnace transformer?

Cost to Replace a Furnace Transformer Replacing a transformer in a furnace costs $100 to $175. The part alone only runs $20 to $40 with labor making up the rest. The transformer converts incoming electrical power into lower usable volts.
