Customer thinks that the igniter of his furnace went out. His thermostat says that the heat is on but it is blowing cold air. Upon diagnosis, our technician replaced the old fail carbine hot surface igniter with a new one.

Customer called on behalf of her elderly father and stated that the electric furnace in his mobile home wasn't working. Upon investigation, our technician found that the breaker panel at the furnace has failed. Voltage is coming in on the line side but not transferring over to the furnace due to breaker failing. I tried to replace fuses but that did not solve the issue. Replacement is needed for further diagnostic.

Customer stated that she had a house sitter stay at her home who messed with the thermostat. Now the furnace blower is running continuously and is blowing cool air into the home. Upon diagnosis, the technician found that the fan was continuously running due to being set on the "on" position on the thermostat. Instead, the technician performed a gas furnace maintenance on the unit. We found that the unit was running well for its age, however the blower wheel was dirty and the hot surface ignitor was out of range. We recommended repairs prior to next winter or upgrade furnace due to age and efficiency.

Customer stated that their furnace hasn't been working properly. In order to get the furnace running he had to shut off the gas, turn the furnace off and then back on. After doing that, the furnace will work for a short amount of time but would like to have his furnace looked at by a professional, as this problem has been continuous and they woke up to no heat. Upon diagnosis, our technician found that the unit needed a new primary circuit board.

Customer stated that they did not have heat. Upon diagnosis, the technician found that the thermostat was not communicating with the module. We disconnected everything and reset the thermostat to factory defaults as it was not set up for the heat pump, it was set up for heating only. Once we reset everything, the module, thermostat and outdoor sensor all synced up. All operations normal at this time. Remove low-voltage wiring between thermostat in module to have the thermostat communicate wirelessly.

Customer stated that their gas furnace was blowing cold air. Upon investigation, the technician found that the thermostat was working intermittently. On a call for heat only the fan was being powered and voltage was not being sent to the W terminal at control board. Jumping the terminals at the board gave normal operations for a call for heat so issue is with thermostat. I installed new T4000 thermostat and unit is operating well

Customer requested standard maintenance to be done on her air handler and electric furnace. She mentioned a concern with the way their venting is set up but said there were no operational issues. Before we could complete regular maintenance, we discovered that a sequencer has failed. This makes the furnace operate at half its capacity and will need the sequencer replaced in order to function at full capacity. A universal sequencer might work however the furnace is from 2016 and may potentially be under warranty, we will investigate further and figure out best route for repair.

We recently installed custom'er furnace however the customer stated that their heat will not turn on. The technician arrived and found a cold house. Thermostat set to 68 house temp was at 60 hasn’t came on all day. Furnace fault code was flashing 8 time says it the igniter or grounding issue. I tested the igniter and it was at like 54 olhms which is like brand new. So I checked for proper grounding. And found inside the EAC a ground screw that wasn’t connected connected it with the ground screw. See pics for more information. Ive cycled the furnace on and off 6 to 7 times and it fire right away with no concerns. All operations normal at this time.

customer says furnace is currently working properly now, however yesterday it was not. He said they set the thermostat, furnace started normally, flame came on for about 5-6 seconds and then it shut off. He said it displayed error codes 10, 11, 13. Upon investigation, I found that the flame sensor was dirty which was not sending clear signals all the time even when flames are present. I pulled sensing rod out and cleaned it, after reinstalling the micro amps are 4.0 which is good. I inspected all other components and all are within manufacturers specifications. Recommend annual maintenance and blower wheel cleaning. Unit is operational and out put at nearest vent is 129 degrees.
