Could forgetting to change a $25 filter end up costing you a whole new furnace? ❄️🏠

This episode is about the realistic side of homeownership — how small maintenance habits get overlooked, why tiny issues quietly snowball into expensive repairs, and how understanding the basics of your HVAC system can save you thousands.

🔎 What You’ll Learn:

  • Why airflow is one of the most important parts of keeping your AC system running efficiently

  • How a dirty or neglected filter can cause your AC coil to freeze into a block of ice

  • What happens when that ice melts — and how water damage can destroy a furnace from the inside out

  • The truth about opening windows at night and whether it actually saves money

  • Why closing basement vents only works on certain newer furnace systems

  • How east and west-facing windows can quietly drive up cooling costs during the summer

  • Why thermostats aren’t really about the “right” number — they’re about what makes you comfortable

  • The importance of small, preventative maintenance habits and why they always cost less than emergency repairs

Jamie breaks down how small HVAC maintenance issues can quietly turn into major repairs — from frozen AC coils to serious furnace damage. He also explains why trusted professionals matter: they catch the problems most homeowners don’t even realize are happening.
