Today I came to the Cheng’s hawk land home because the furnace stopped working. Upon diagnostics I found the igniter is weak and pressure switches need to be replaced. These can cause damage to the control board. I went over the options with Friday, he has decided to just replace the condensate pressure switch for now. I have jumped the switch today so he has heat until we can return to replace it. 50% paid today with the remainder due at time of job completion. 25% restocking fee should the job be cancelled.
