Having a home inspection done prior to purchasing is a very intelligent investment. Knowledge is your greatest asset in making the right decision. Choosing the right inspector is very important. Aaron's Home Inspections was established in 2007, the first year Maryland required all home inspectors to be licensed in order to be a home inspector. 30 hours of continuing education is required per year to maintain the license. I have previously worked in the HVAC industry for 13 1/2 years, during which time I also attended Rets Techincal Training Center in the evening for 2 1/2 years, becoming certified for type 2 & type 3 high-pressure systems through Ferris State University.
