Understanding Your HVAC System – The Basics

Your HVAC system is like the lungs of your home, and the air ducts serve as vital respiratory passages. 

These hidden highway systems within your walls, ceilings, or floors significantly affect your home’s air quality and thermal comfort. Acting as conduits, air ducts transport the conditioned air – either heated or cooled – from your HVAC system into the rooms of your home. 

Used air is then recycled back to the HVAC system for conditioning, providing a continuous source of fresh, comfortable air. Acknowledging how air ducts function is the first step toward creating an effective HVAC system – not only can temperature be managed effectively with River Valley Air Conditioning Inc, but they can also help ensure peace and comfort in the home.

Signs Your HVAC Ducts May Be Leaking

Leaks in HVAC ducts often exhibit subtle indications before becoming clearly obvious. Let’s outline some of the key indicators of a leaking duct and what you should keep an eye out for in your system.

  • Increased energy bills: If your monthly utility bills have suddenly surged without any significant change in usage, this could be a sign of an air duct leak. An improperly sealed duct allows treated air to escape, causing your system to work harder and consume more energy.
  • Uneven heating or cooling: Noticing some rooms are colder or warmer than others? Leaking air ducts may be to blame. When air escapes through leaks, it leads to an uneven distribution of treated air across your home.
  • Dusty interiors: Excessive dust in your home can also be a leakage indicator. Leaks can pull dust and dirt from unconditioned spaces into your HVAC system, dispersing it throughout your home.
  • Poor air quality: If you’ve noticed a decrease in your air quality or family members displaying increasingly symptomatic allergies, this could indicate a leak in your HVAC ductwork. Leaks can draw in pollutants, allergens, and mold from outside, spreading them within your living spaces.
  • An aging HVAC system: Is your HVAC system over 10-15 years old? If so, leaks are likely to develop. Aging components and worn-out sealants can lead to air leakage, causing your system to perform less efficiently.

Air Duct Testing for Leaks – An Expert Guide

While professional assistance is always recommended for extensive air duct issues, you can do a basic leak detection test at home. Here’s a step-by-step guide on how to test HVAC ducts for leaks.

Step 1: Visual inspection

Begin your visual inspection of the ducts by observing their joints, and checking for signs of wear or damage, such as wear, tear or holes. Be sure to wear safety goggles and gloves for added protection!

Step 2: The smoke test

Turn off your HVAC system. Light an incense stick near duct seams and hold it near them; if any smoke wafts into a duct or wavers over time, that could indicate leakage.

Step 3: Pressure test

For a more technical evaluation, using a special fan to pressurize the system can provide more accurate results than simply checking air return and supply registers; any change in pressure indicates leakage in the system.

Step 4: Do the classic hand test

Switch on your HVAC system and place your hand around its ducts; if air starts blowing from them, there may be an air leak somewhere.

Step 5: Professional leak detection

If the leak seems severe or you require a more accurate assessment, hiring a professional leak detection service might be best. They have access to special tools such as the duct leakage tester (DLT). These specialized instruments will give them an accurate assessment of your system.

Detecting and fixing HVAC leaks is crucial for maintaining a comfortable, efficient home environment. Don’t let minor leaks become more significant issues. For assistance with HVAC maintenance or air duct testing for leaks, contact River Valley Air Conditioning Inc today.
