Some varieties don't bloom year after year. The Mophead (rounded) varieties are notorious for not blooming year after year.
Also, a lack of blooms could be due to pruning at the wrong time.
Or... A general lack of phosphorous in the soil, which you can apply throughout the growing season to encourage blooms.
The smooth hydrangea (Hydrangea arborescens), bloom on new wood so if you prune in late winter or early spring, you won't accidentally cut off this year's flowers. Others, like some mopheads and many big-leaf hydrangeas (H. macrophylla) bloom on old wood, so any late-season (or fall or winter) pruning you do erases next year's flowers. To stay on the safe side, and if you don't know which type you have, prune off only the spent blooms.
Good luck! I hope this helps.

hydrangeas can be a bit fussy....they need good sun, rich soil and plentiful watering. they are also quite hungry plants and will benefit from a feed every spring.
i have a hydrangea which had poor flowering for a year or two and found that increasing food and water really helped. i also pruned off about half of the flower clusters before the flowers opened to reduce the strain on the plant and this also helped as the remaining flowers were much stronger.

hydrangeas prefer medium to high elevation.it means the temperature shoukld be at least around 25 degrees centigrade or below but not in chiling point(10 C)if your place is too hot for hydrangeas place them in aareas with trees so that they will not be exposed to too much sunlight and change the soil from clay to loam oir sand with compost.

Mine are behind this year because of a late freeze. They basically were growing and had to completely regenerate. The plants are re-growing, but I'm still hoping for blooms

It could be the soil, amount of sun, and amount of water...how old are they?
Here's a plant file from the Dave's Garden website, it sums it up for you.
