There are a lot of upgrades that you can make to any house, regardless of its age.
I have solar panels on my roof for supplemental power.
They charge supercell batteries that I use for backup electricity if the power goes out during a storm for instance. I can also use solar energy to power tools and appliances in my garage. This is helpful whenever I’m trying to save on electricity costs in the summer or winter when I’m cooling and heating my house respectively. Another upgrade that I added to my house was the integrated lighting system with automation and smart controls. I have the power to adjust my lights anywhere in my house or on my property from the touch of a button on my smartphone. The app is accessible anywhere and it’s easy to control the lights when you’re away on vacation or for work. This is helpful because it can make your house look “lived in” if it’s getting cased for a burglary. Having your lights turn on and off at strange times through the day and night makes it look like someone is living inside, regardless of whether or not there is a vehicle in the driveway. The most recent home upgrade that I made was adding UV-C bulbs to my heating and cooling system. You put one bulb on either side of the evaporator coil in your air handler and they help sanitize the air moving through your HVAC system. On top of that, these UV-C lights keep the evaporator coil clean and prevent microbial buildup from forming.
