We found that exterior window shades DRAMATICALLY lowered our AC costs. Here in Arizona, the sun is intense so when the afternoon sun bares down on the front of our house, the interior window blinds (5 windows) helped somewhat but a LOT of heat still entered. We purchased Bali exterior shades which are manually raised and lowered (motorized versions were way beyond our financial means). Now our AC not only runs much less, the interior temperatures are more constant.

We live in a three story 110 year old house. Installing a smaller furnace/AC on the third floor .This unit cools the third floor and the bedrooms below. Going upstairs in the summer we find it is much cooler than on the first floor. A very affordable option . The venting was easy and as cold air falls the smaller unit cools the whole house much of the time. We rarely use the larger unit that cools the basement and first floor. Low tech and affordable.

This is a great start to HVAC systems, but it is missing the all-important, super efficient mini-split option for consideration. Having a heating and cooling system that is fossil-fuel free is an all too important option, while we grapple with this climate emergency. This is especially true if you have solar panels! If not, you can sign up for community solar so that your electricity is coming from solar, and not a dirty power plant. We all need to make thoughtful decisions while choosing systems that will run our house's heating and cooling for decades to come. We live in NY and have used mini-split units to do full buildings as the sole heating and cooling source. Yes, they can handle our very cold winters and super hot summers! The rebates are excellent and make them affordable and pay off quickly over the following years.
