AC OWNERS! Please NEVER Do THIS to Your AC! (15 Expensive Mistakes)

Before you pay for another AC repair or sign a replacement quote, my HVAC field guides show the settings, fixes and contractor questions that prevent these AC mistakes: https://exposi.pages.dev 15 expensive AC mistakes homeowners make, from the wrong filter to a skipped warranty form. Every one of them was avoidable. This video walks through the AC maintenance, airflow and paperwork errors that kill compressors, flood ceilings and void manufacturer warranties. You'll learn why a MERV 13 filter can burn out a blower motor, why closing vents freezes the coil, and why a refrigerant top off means you have a leak. We also cover AC warranty registration deadlines, the Manual J load calculation a contractor should show you, and the static pressure question to ask before replacing your system. None of these AC mistakes are machine failures; they come down to airflow and paperwork.
