We've used Three Generations for 20 years. Dale replaced our furnace and we had heat back before dinner. Honest pricing, wonderful people. They're the only HVAC company we'll ever call.

My furnace went out on a Thursday night in January. Dale's crew was there by 10am Friday and had it fixed by noon. Grandma Earl would be proud.
-
Three generations of my family have used Three Generations HVAC. The quality and honesty never changes. That says everything.
-
After being upsold by two other companies, Dale came out and told me I just needed a part — $180 vs $3,200. I cried. Honest people are rare. These folks are the real deal.
-
Annual maintenance plan for six years. Our system is 18 years old and still running perfectly. Worth every dollar.
-
Dale installed our new AC and was patient enough to explain everything. He even called the next day to make sure we were cool. Old-school service. I love it.
