Was making a weird fizzing noise earlier in the day. Now it just doesn’t work. Not even moving at all. Any idea what the issue might be and how much it may cost to fix? I’m just a bit worried about it. My wife is pregnant and we’ve already been paying hospital bills due to high-risk pregnancy heart checks due to her heart issues. We don’t have thousands of dollars to pay for a new A/C system. We simply don’t have that. I’m not sure what our options will be at this point. Any actual advice would be appreciated.
