Smtihville Heat pump repair I performed the heating evaluation in Smithville on the gas furnace. This system is older and has signs of deterioration. The gas valve could not be adjusted because the spring is stuck. I spoke with the client about several of my concerns and let the client know I don’t recommend putting money into a repair and that I feel replacement is the best option at this point. For now the system is operating safely. The client will also get some carbon monoxide detectors installed in the home.
