Proper Heating Operation (start-up, run, shut down). Some issues that continually seem to raise questions and wreak havoc among inspectors, buyers, sellers, and Realtors alike include:
(a) when does one of the new furnaces with an inducer fan need a lined chimney;
(b) does seeing a clay tile sticking out of the masonry chimney top mean the chimney is fully lined (if not when should we put in a steel liner kit);
(c) what signs should an inspector look for that might indicate a damaged heat exchanger on the newer 80% or 90% furnaces with their limited access to heat exchangers;
(d) heavy white corrosion at flue joints ….. Why and should it be called out;
(e) what to do with condensate on 90% furnaces in crawlspaces … Will going outside freeze, etc;
(f) home inspectors SoP say do NOT turn on AC’s below 60 or 65 degrees … Talk about this;
(g) how to quickly tell the difference between steam and hot water boiler for new home inspectors;
(h) what boiler issues arise frequently / what controls are mandatory for each type unit;
Heat Pumps
To a lot of inspectors, a heat pump is a confusing system. Can the instructor “desimplify” heat pumps for us. When you leave this class you will know what a heat pump is, how it works, and how to inspect them.
