The installation of my HVAC system went well, but follow-up wasn't very good. I paid what I thought was a bit too high a price, $11,000 for an 800-square-foot home, but I can live with that. After the installation, which included having an installer crawl around under my house, I had two new problems: a dead animal smell coming out from under the house, and the water coming out from my kitchen faucet had been reduced to a trickle. I had the company send someone out, but had to pay for a service call. The service call was not helpful at all. The technician reported that it seemed like a "plumbing smell," and as far as the trickle coming out of the kitchen faucet, he gave me some line of unhelpful nonsense about how I'd have to basically become a plumber and deal with it myself. I am still living with the faucet problem — I'll attach a photo showing the water coming out at FULL STRENGTH. As far as the dead animal smell, of course that's exactly what it was, not a "plumbing smell." It was a big dead cat that, maybe just by coincidence, appeared under my house just after the installers were working there. I'll also try to attach a picture of the dead cat, but I had to pay to have someone else come out to find and remove the cat. So I keep shelling out extra money after the installation, and I still don't have my kitchen back working the way it was before.
