If you own your home, and are thus liable for paying for repairs yourself, and have central heat/air, double-check where the condensator for your AC drains. And where your blower motor is. And if the two are too close together, think about paying an HVAC expert to change where the condensator puts the water.
Yes, we learned this the hard way.
Last week, very early on Tuesday morning, we had an...issue. The blower stopped. Completely and entirely. The compressor still kicked on, but the house had no AC for all intents and purposes. We tried turning the system off, then back on. We tried flipping the breaker for it. No dice. Called the company that had put the system in, and they said they likely wouldn't be able to get to us for a couple days, but might have been able to slot us in that day.
The high was projected to be triple-digit, with higher heat index (thanks, Missouri humidity). For the rest of the week.
We called someone else. They made it at five pm that day. Crawled under the house where the blower unit was, and found that the motor was burned out. Completely. Dead, with no chance of resurrection.
The heat pump is only 5 yrs old. It shouldn't have died, were it properly installed...which it wasn't. Turns out, the condensator drained onto the ground under the house...under the blower motor. Which raised the humidity under the house significantly. And wound up killing the motor.
It was, thank God, still under warranty. For 30 more days. And the place that installed the heat pump had one in stock. The guy that we had out who found the problem picked it up Wednesday morning as soon as they opened, got over here and installed it, and put in a drainage system and pump to put the water from the condensator out from under the house.
Overall, we were out a bit north of $350. It could have been far, far worse, if this had happened a month--or year--later.
Check your HVAC units. Make sure proper function isn't going to cause a catastrophic mal- or nonfunction. Spending a little now will head off spending a lot later.
