Heating and cooling demand swings with the weather, and your feed should swing with it. During a heat wave, people want quick checks they can do before calling: is the breaker tripped, is the filter choked, is ice forming on the lines. A short clip answering those questions gets shared because it is useful right now, and it quietly positions your company as the one that knows.
Shoulder months are for planting
Spring and fall are when you have room to talk about tune-ups, duct cleaning, thermostats, humidity control and air filtration. This is also the window for membership reminders and for heat pump education, because a homeowner who is comfortable today is more willing to think about next year.
Content that reflects your trade
Good HVAC posts come from the work itself. A before and after of a cleaned blower wheel, a tech explaining why a capacitor fails, a new install with tidy line sets, a crew member's anniversary. Stock photos of smiling families on sofas do very little. Your own trucks, uniforms and job sites do much more.
