![]() Failed starting components, in particular, can prevent your blower (indoor unit) or outdoor unit from starting properly. While we're on the subject of heat pumps, let's just acknowledge that all kinds of components can go bad for any number of reasons. In any case, always keep an eye on your auxiliary/strip heat status in the winter. In some cases, it might even be more cost effective to replace the system with a new one that uses newer, R-410A refrigerant! It's much less costly to recharge the refrigerant (and fix any leaks) than to replace your compressor (and deal with having no heat). If the level is too low for too long, the compressor might overheat and fail. If you recognize your heat strips coming on with increasing frequency, it might be time to increase your refrigerant charge. When that happens, your heat strips might come on more often than you want them to.Īnd we all know that heat strips can lead to exorbitant utility bills. Heating your home with a heat pump? If you are, it's possible for your refrigerant level to get a bit too low. If they're on their way to a slow death, we'll let you know it's time to replace them. Since capacitor failure is so common, we always check the tolerance of your capacitor(s) during routine inspections. ![]() The worst case scenario? A dying capacitor leads to a blower malfunction, which is a really costly repair. In some cases, the capacitor just won't start the blower. If the tolerance is below a certain level, your blower might not achieve the proper RPM. Have you ever seen your blower capacitor? It usually looks like a big battery.Īnyway, the capacitor starts your furnace when the thermostat setting tells it to turn on. It tells us whether your furnace is burning too much gas. That's why we always perform a combustion analysis during our annual furnace inspections. ![]() We get calls when #2 happens - especially on really cold days when the furnace can't keep up.
