In this short video, Derek Cole addresses three common HVAC misconceptions. First, he refutes the idea that maintenance is only needed after a unit breaks down, explaining that preventive maintenance every six months helps catch problems early. Second, he clarifies that while modern thermostats are more accurate than older models, they still require periodic checks and should not be assumed perfectly precise. Third, he debunks the belief that raising the thermostat setting will heat a home faster; only heat pumps or two‑stage units can respond to higher setpoints, whereas single‑stage systems will not heat any quicker regardless of the thermostat position.

Number 4: Maintenance is only needed when my unit breaks down. No, that is not true. You want maintenance twice a year because you want to be preventative. Having your maintenance done every 6 months or so on your unit is actually a good thing because you can catch those problems before you have situations. 5: The temperature on the thermostat is always accurate. No, today's thermostats are a lot better than they used to be, but it still needs to be checked. Number 6: Hey, if I crank up the thermostat, it'll heat the home faster. If you have a heat pump or a two-stage unit, it actually may heat faster because it's calling on those stages of heat to activate faster. But if you don't, then you're wasting your time. Doesn't matter how high you go on that thermostat, it's not going to do it any faster.
