About Home Ventilation Systems
Modern homes are sealed tighter than ever, which is great for energy bills and rough on the air inside. Without a way to swap stale indoor air for fresh outdoor air, moisture, odors, and pollutants simply build up. This section explains home ventilation in clear terms, from humble bathroom and kitchen exhaust fans to whole-house systems and heat or energy recovery units. We break down how HRV and ERV systems work, when each one makes sense, and what balanced ventilation actually means for comfort and health. You will also find practical help on fan sizing, duct basics, run times, and the signs that your home is not breathing well. Whether you are fixing a stuffy bedroom or planning ventilation for a tight new build, these guides give you the reasoning, not just the rules, so your choices hold up long after the install.
