Surge protection, HVAC
I'm new to the forum and new to home ownership as well. I live in Durham, NC area so needless to say it's pretty hot this time of year, and most everyone has their AC running. On Saturday we went out to dinner and when we returned I noticed that it felt quite hot in the house. I went to the thermostat and turned it down a bit but nothing happened. I then went outside and noticed that the breaker had been tripped so I reset it, but, the AC, nor the blower, would run.
On Sunday our HVAC person came by and it took him about 2 minutes to look at the (I might have this name wrong) circuit board or electrical board, and notice that it had been fried. In one place it was just charred, completely.
Obviously the board needs to be replaced, and I talked to him about what happened and he said that it was likely a surge - could have come from the power company, etc. So then I asked him if it was possible to prevent those surges - was there anything that I could do to protect myself from this happening again - he said that he doesn't see this too often and that really, no, there wasn't too much I could do.
My unit is '99 Comfortmaker - gas furnace and AC unit combined, and he said it's a pretty simple unit; main components being the heat exchanger (I just replaced the heat exchanger), the blower, the electrical panel and the compressor. I'm throwing this in there because in some of the research I've done I noticed that most new units are a bit more complex and sometimes include delays, which keep the unit from trying to turn back on after a power outage.
Honestly, I'm so new to all of this that I just don't know what to do - obviously I'll replace the circuit board, which is being done today - it's about a $450 repair - but should I worry that this will happen again? Our repair person is someone I trust, and he said it was likely a fluke, but like most folks I'm not in a position to handle a $450 fluke whenever the power company has a surge! Is there something I can do to reduce the risk of a surge?
Thanks very much,
