I have two HVAC systems in my house and noticed when they both come one I am using 9kWh of energy total for the house. When they are off, I am under 1kWh usage typically around 0.8 during the day and 0.5ish at night
My HVAC systems are 18 years old and likely not very efficient. Last year when being serviced, the tech said one of my systems is on its last legs, but could have been trying to sell.
I read that going to a 16 or 18 SEER HVAC will reduce electricity by up to 40%, not sure about gas for heat in the winter.
From a Net power usage throughout the year that would be a big chunk against an EV. I would expect to replace my wife's car with an EV within the next 2-5 years
Knowing that my HVAC systems are near their useful life, I wanted to be prepared
What I am asking for is any real use experience with improvements in Electricity and gas by swapping out for a more efficient system.
