It was pruned last year. Could this be the problem?
Look to the variety for answers why the hydrangea is not flowering. This article should help:

I know that changing the acidity of soil allows you to turn hydrangea flowers from pink to purple to blue. However, I notice that some shrubs in my neighborhood have light blue flowers (such as my hydrangea), while others have a deeper, darker shade of blue. I see the same within pink and purple varieties---variations in color saturation as opposed to the color itself. Is there a way to control this or encourage deeper colored flowers? Or does it depend on the plant variety?
This Extension fact sheet says adding aluminum sulfate to the soil will make the blues darker.

Leaves appear to have major blisters on the leaves with slight curling. One is in side yard, other in back yard. No insects appear under microscope. Thank you!
The presence of pests may actually be a sign of another problem that is causing your plants stress. Insects that may trouble the hydrangea include aphids, leaf tiers, rose chafers, scale and four-lined plant bugs. Aphids distort the new growth and coat the leaves with sticky honeydew.
I would treat with Neem Oil, treat every 3 to 4 days for 2 weeks.

have both types
Generally, you will want to select a branch of at least 6 inches, and do so when there are no flowers, but new vegetative growth.

This article will go over several of the types of hydrangeas, and when to prune them, which will be a good time to assess where your new cuttings will form: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm
I live in South Alabama. Plant zone 8b. I purchased an Incrediball Hydrangea in April of this year. I planted it immediately and it has bloomed and looked beautiful. In the last few days the leaves have looked wilted and wind burnt. It is planted next to our air conditioning unit. I have a moisture meter and it reflected it was dry but when I stick my finger in the soil, it feels moist. I do not want to loose my hydrangea. What do you suggest I do? If I need to move it, I will. Thank you for your help. Jenny Allen
The air conditioner unit may certainly be the cause of the leaf damage and plant decline.
It's possible that as the plant grows it will be less disturbed by the air movement of the AC unit; but moving it may be the safest way to save the plant.

I bought a blue hydrangea that I think is Endless Summer (I don't remember what the tag said), the blooms are turning a brownish color. The leaves are fine and green, though the bush had some sun damage on one bunch of blooms when I bought it, but now the rest are starting to tuen green-brown. I try to keep the soil moist and know it may need some nutrients, I'm just not sure how to fix it. How can I get it vibrant and blue again?
It looks to me that the blooms are simply fading, the fate of all flower blossoms. The good news is that Endless Summer is a repeat bloomer; when the flowers are no longer attractive, cut them off.
