Top 5 Things HVAC Companies Don't Want You To Know How To Do!

Your HVAC system has five simple maintenance and diagnostic tasks that take fifteen minutes or less, cost almost nothing, and can save you thousands of dollars in unnecessary service calls and equipment replacements. This video walks you through clearing and maintaining your condensate drain line and float switch, taking a proper temperature split measurement with two cheap probe thermometers, reading your own data plate and understanding exactly what your parts warranty does and does not cover, cleaning your outdoor condenser coil and furnace flame sensor yourself, and using static pressure and temperature rise readings to find out whether your system was ever installed correctly. Along the way, the video covers real HVAC class action lawsuits involving copper evaporator coil corrosion and refrigerant top-ups, explains how to request a Manual J load calculation, and draws a clear line between what homeowners can safely handle and where a licensed technician is genuinely required. Whether you own a central air conditioner, a gas furnace, or a heat pump, understanding delta T, warranty registration deadlines, and duct system sizing can fundamentally change every conversation you have with a contractor. #hvac #homeimprovement #airconditioner #furnace #diy #homerepair #hvactips #energyefficiency #homeownership #maintenance
