Are EVs an Opportunity? - Short #222

In this short podcast, Bryan talks about electric vehicles and whether EVs present an opportunity for HVAC technicians. The residential sales lead at Kalos recently mentioned that keeping an EV in a conditioned garage is advantageous, and it's an upgrade we can offer our customers.

In hot weather, EV battery performance and health can be degraded. On top of that, the vehicle consumes power when the vehicle gets hot so that the A/C can control the climate inside the car and preserve the interior. Most people also charge their electric vehicles in the garage at night, so it would stand to reason that conditioning the garage can yield energy savings and improve vehicle longevity. Attic encapsulation above the garage is also an option to limit warm, moist attic air from leaking into the garage; HVAC upgrades can include using closed-cell foam to encapsulate the attic and install a dehumidifier in there.

Conditioning a garage requires you to think about insulation. In our market (Florida), block walls don't insulate very well. Even when we can't do very much with the walls, we can usually use some polyiso boards inside the garage. However, we could get some moisture challenges, and carbon monoxide could be an issue if combustion appliances are in the garage (like furnaces, water heaters, or gas-powered cars). We can recommend using heat pump water heaters, and we should quote a low-level CO monitor in cases when garages have a CO risk. 

It's important to make sure the garage remains separate from the rest of the house even when we do these upgrades. Keeping the garage separate helps prevent chemicals from getting into the airstream, especially yard chemicals or cleaners.
