Duct Testing and Sealing in Denver, CO

Proper air conditioning, heating, and ventilation for a house requires ductwork that’s airtight and in good condition. (Unless the house doesn’t use ductwork.) Only airtight ducts allow the ventilation system to retain air pressure from the heater and AC all the way to the various room vents. Ductwork with air leaks leads to comfort issues, humidity changes, a rise in energy bills, and even low indoor air quality.

Since you can’t see most of the ductwork in your home, you’re probably wondering how to know the ducts need repair work in the first place. One way is through house duct testing services. Testing will then show where duct sealing services are required. Cool Sunshine Heating and Air Conditioning, Inc. offers both duct testing and duct sealing for leaky ducts in Denver, CO. We started in business twenty years ago working on custom ductwork design, so we are especially skilled at taking care of ventilation systems, no matter what they need. Call us today to schedule duct testing in Denver, CO and the surrounding area.

What Signs Tell Me That Duct Testing Is Necessary?

First off, you may want to have your ducts tested even if there are no warning signs. If you’ve lived in your home for at least five years and have never arranged for duct testing, we strongly recommend you have it done as a precaution. Five years is enough time for ductwork to develop air leaks from basic wear and tear. Testing ducts will allow you to find out if there are problems before the warning signs start.

Otherwise, here are some indications of leaky ducts:

  • An unexpected and steep rise in your energy bills
  • Rattling sounds from the ventilation system when the heater or AC turns on
  • Moldy or musty smells coming from the room vents
  • Hot or cold spots appearing in rooms
  • Low airflow from the vents

How to Test Ducts, the Professional Way

The question "How to test ducts?" is easy to answer: call on HVAC technicians. You can’t examine your ducts on your own. The job requires skilled professionals with special equipment. To find out if ducts are losing air through gaps or holes, we attach a powerful vacuum onto the main duct coming from the HVAC cabinet and seal off all the room vents. The vacuum then raises the pressure inside the entire ventilation system, and we use a manometer to measure how rapidly pressure declines. The faster the drop, the more the integrity of the system is compromised by leaks. We’ll use this information to pinpoint how extensive the leaks are and where to find them.

Duct Sealing Done Right in Denver, CO

No, this isn’t a job for duct tape! Oddly, that’s not what duct tape—the type you can purchase in stores—is actually used for. Professionals have different tools to close up air leaks and restore the integrity of ductwork. One is mastic sealant, a resin–based sealant that creates a flexible and heat–resistant seal. Another tool is metallic tapes. These are the "true" duct tapes, and they offer a mechanical seal that will last for many years. The HVAC professionals will determine the best technique. In some cases, you may require further duct repairs or replacements.
