I live in CO and the first couple years the trees had loads of peaches. Last year there were very few and I blamed a late frost, but this year there was not any late frost and still I did not notice them flowering. They are on a drip system since I am on the east side of the Rockies (high plains desert area) and I fertilized them with Tree Spike for Fruit trees. They are healthy and now have large trunks and are very sturdy.
There are a few reasons plants do not bloom. Most common, for plants that bloomed in the past and do not bloom now, is that they have either too much nitrogen or too little phosphorous. Give the tree some bone meal and this will help balance out either issue.

Trees are about 4 years old. I live in Denver, CO. Natural soil is high clay content, but I planted with lots of compost and peat mixed in.
There are many reasons that this could happen. I would look to make sure that it is getting enough water and, if you have not fertilized, I would go ahead and do this (after the plant has been well watered).
This article will have some other suggestions on what it could be:

What would cause most of the very young peaches to fall off the tree?
There are several things that can do this, but likely it was poor pollination. If the flowers are not properly pollinated, the tree will drop the fruit as they will
not produce a good seed. Here is some articles that you may find helpful:

I have a dwarf peach tree that most of the peaches are getting a clear goo on them, but I don't see any holes in the fruit. I did notice a lot of sap oozing from different areas of the tree trunk. Any ideas what this could be, and can I save my peaches?
This is a sign of peach borers. This article will help:

Why are the leaves on my peach tree turning yellow and dropping off? I pruned it last year in late Aug. Now the leaves are yellow and falling off, and I have very little fruit this year, where as in previous years have had lots of peaches. The tree is 5 years old.
It is either a watering issue or a nutrient issue. Make sure the tree is getting water daily, twice a day in temps over 85 F. And give it slow release (balanced) fertilizer that will continually feed it. This article should also help: https://www.gardeningknowhow.com/edible/fruits/peach/fertilizing-peach-trees.htm
The peach tree drops all of the peaches before they ripen or are ready to be picked. They are hard as a rock and we never get to keep any for eating. Also, the squirels get to them first. Do you know what the problem can be and how to get at least a few peaches to eat from the tree?
This is normally caused by either a watering issue or a fertilizer issue. I would recommend phosphorus heavy fertilizer. This will help with fruiting. As for fruit dropping, this article should help: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-fruit-drop.htm

We live in northeast Pa. We have a 5-6 year old dwarf peach tree. We treated the scab and still get peaches that look like an insect "stung" or bit them. A droplet of clear sap-like material is on the outside of the peaches. I can't find out what it is and have yet to eat one of my own peaches. Can anyone please help me? Thank you.
You could try this home made insect spray; pepper and garlic spray 1/2 cup of fresh hot peppers 2 large cloves of garlic 2 cups of water 1 Tbsp. vegetable oil. Liquefy ingredients in a blender and strain the mixture through a sieve lined with a handkerchief. Transfer into a spray bottle and label. Spray the upper and lower leaf surfaces of plants that show insect damage. This spray contains enough hot volatile oils to burn the chewing and sucking mouth parts of insects, but wear rubber gloves and eye protection as this can burn your skin and eyes, hope this fix's your problem
