Energy efficiency is now a major consideration for new home construction, but even older homes without state-of-the-art appliances can benefit from being retrofitted, either entirely or via certain components. Inspectors should be aware of these options, as well as the many configurations and multiple uses of heating appliances, by reading Inspecting Gas-Fired Boilers.
The majority of new home construction is deadline-driven, which means that, sometimes, minor but essential work may be performed haphazardly or not at all. This is especially true of sealing around exhaust fans and ductwork. If the opening cut for the installation of the fan box or duct leaves large gaps around the unit, air can escape into unconditioned spaces and create airflow and moisture problems that don’t reveal themselves until they become critical. Proper installation at the outset can help prevent such issues. Inspectors can read more about them in Inspecting for Air Sealing at Kitchen and Bathroom Exhaust Fans.
Inspectors who inspect homes that are being built or retrofitted with newer HVAC systems should know something about ductwork and air returns. Making sure that airflow and return air are being moved through the system properly is vital for energy efficiency and comfort. Read more in Inspecting Ducted Returns.
Cooling is essential for homes in regions that experience hot weather. And it’s vital to get the right installation and balance for homes in climates that are particularly humid. Find out more by reading Inspecting Whole-House Dehumidification Systems.
Before the weather heats up, it’s important to have a home’s cooling system serviced so that it runs optimally. And it’s just as important to have the right size system installed in the first place – not just based on the size of the home, but also the home’s climate zone. Evaporative cooling systems are affordable alternatives to conventional central air-conditioning systems, but they don’t work everywhere. Find out more about them by reading Inspecting Evaporative Cooling Systems.
New homes are being built to be more airtight and energy-efficient. That’s why it’s more important than ever to make sure that their cooling systems are properly sized and installed. Whether your clients are in the process of building their home, or you’re inspecting their existing home, don’t let them waste money or energy. Read up on some helpful tips in Inspecting Compression Cooling Systems.
Energy efficiency is a top priority for homeowners. Advising clients on how to lower their heating and cooling costs while maintaining comfort is important for home inspectors. When homeowners have taken steps to make improvements, there are special inspection considerations.
