How to Prepare Your AC for the First Heat Wave As temperatures climb with the season’s first heat wave, your air conditioner is asked to do more work than it will on milder days. A little preparation now can help prevent common problems—like poor airflow, frozen coils, or system shutdowns—when demand spikes. Start with the simplest win: check and replace the air filter. A clogged filter can restrict airflow, make the system less efficient, and cause the indoor coil to overcool and freeze. If the filter looks dirty or has been in place for more than about one to three months (depending on usage and indoor air quality), replace it with the correct size and rating. Next, clear the outdoor unit and protect airflow. Make sure the area around the condenser is free of leaves, grass clippings, and debris. Trim back plants or brush so air can move in and out freely. Also remove any items stored nearby that could block vents during windy or s ... Read more »
Fresh Air Ventilation: Why Modern Homes Need It
As homes become better insulated and more airtight, they also become less forgiving: contaminants and moisture that used to leak outdoors now build up indoors. That’s why fresh air ventilation systems have become increasingly important in newer homes, where air exchange is often limited by design.
Fresh air ventilation brings outside air into living spaces while managing how stale air is exhausted. The goal isn’t to “blast” the house with outdoor air; it’s to maintain healthy indoor air conditions consistently—especially as energy-efficient construction reduces natural ventilation.
Why tighter homes need planned airflow
Many modern building envelopes are sealed to improve energy performance. While that reduces drafts and heating or cooling losses, it also limits the background leakage that used to dilute indoor pollutants. Without a dedicated ventilation strategy, levels of a ... Read more »
