There’s much more to residential spaces than first meets the eye. In fact, plumbing, lighting, and HVAC systems often have a greater impact on a home’s comfort and long-term livability than its design or style. Homeowners often look to real estate agents for advice on when and how to hire a contractor to maintain or upgrade these home utilities, which means it’s important to have a list of trusted professionals to offer clients. Also, when problems with home systems crop up in the inspections process, it’s vital that real estate professionals have a basic understanding about their function to help home buyers and sellers navigate the situation.
