After recently servicing a couple of homes in a 35 year old Greenville county neighborhood, we are finding issues that can only originate from unpermited work. Not only do we find issues that affect the operation and efficiency of the system, but also we discover alarming safety issues. We advise checking your gas furnace exhaust flue attachment – today. These pictures are from two different homes Blue Ridge Heating and Air serviced in this Greenville county neighborhood. When the flue is not physically attached and sealed, combustion exhaust can fill up either your crawlspace or attic. Just as it’s known not to run a car in a closed garage, this is the same principle. Carbon monoxide is deadly. The picture of the charred wood speaks for itself. We strongly advise that you require your HVAC installation company to pull a county permit and inspection when you change your system—This is to protect You. Please look at the details of your estimates to know what you’re getting. Watch out for permitting, venting, labor warranty, duct system sizing, & equipment sizing. Please let us know if we can help you. Click here to schedule a service call or call 864.485.6509.
