We came out because the customer was complaining about a gas smell in the home and we ended up finishing the roof termination to the tankless and giving the whole house a pressure test to make sure there were no leaks. We also soap down every fitting that we can get to and flex to double check everything. We did notice that the fireplace had not been relit and some gas could’ve escaped from that if the gas control was malfunctioning, but we now have the fireplace relit all the appliances working correctly. There was one cover monoxide detector going off in a strange location not close to any appliance so we did remove that for the customer to change the battery out and reinstall it later when everything dissipated. We will also have the master plumber do a wellness check in the morning to reinsure The home is completely safe but the smell is gone and the house is properly aired out so we believe it is currently safe too and have it. Definitely no charge for the call today.
