My AC and furnace apparently decided to conk out at me at the same time. Long story, but suffice it to say that I needed to replace both. I used to rent them, but found out my agreement expired a year ago and they never told me - basically no warranty work, only a new 7 year contract. No thanks. I've moved to a heat pump with a furnace as a backup heating unit for cold Canadian winters, and I must say that I'm impressed. I splurged on the system, but I regret nothing. This is my 3rd furnace in 25 years, so yeah, I'm not going cheap anymore. I love my heat pump. This thing is quiet! I mean, holy crap it's quiet. I've had a central air unit for decades, and that sucker was loud. This heat pump is super quiet, doesn't shake or rumble the house (it's attached via a mount to the wall), and cools very well. I absolutely love this thing. I look forward to see how things work out in the winter, but I'm happy so far.
