Question my old house has drafts

I just remodeled a 22 year old home. The 4 ton heat/air unit is on a true vaulted roof, I'ts 3 years old. After putting in energy saving lights, and new R-38 in the attic this old 2 story still has issues.

The registers pump out the heat near the inside intake, but upstairs and down, the registers can hardly keep up with a trickel of air.

Then when the heater is off and you stand underneath the intake register you can feel a light, but steady cold breeze.

Is there a do it your self way to cheak for duct seals or air-tightness without having to hire some $55.00 hour HVAC guy just to tell me my ducts are loose ???

Any help out there??

Since there are other issues that may need attention and correcting to further resolve the drafty conditions and you already have the answer to the heater problem, I moved you topic to the insulation forum.

Doing so offers you ideas & suggestions for insulating the home.

So I'll tell you for free. You got ducting problems. It's a search and destroy type thing. You'll have to check connections, gaps, etc. on all your duct work, supplies, and returns. Good luck and 55p/hr is cheap.

You can go to http://www.resercon.com/Low.html you have what is known as a low velocity system and it explains how your system works. It also discusses leaky ductwork and how to seal them.
