My wife and I are purchasing our first home and a couple of HVAC issues pertaining to out furnace and water heater came up.
1. The furnace has mineral build up on the top of the burners as a result of condensate dripping onto them. See picture below. I was just wondering if this could indicate a bigger problem with the furnace or if this is a common occurrence with furnaces. The inspector recommended cleaning and servicing the furnace. Anything else we should be concerned with?
2. The water heater is 14 years old obviously at the end of its life. There is a leak from the water heater drain valve (see photo). Is this likely fixable or is this water heater likely on its last leg and in need of replacing? Main question is: Ask the owners to fix it or take the credit and buy a new water heater?
Your help is appreciated.
