@Andre KeyThe commercial air scrubber linked in the previous post will be what you need- BUT, in addition, you will need to clean the A/C coil and probably replace carpet, duct work - cleaning won't help - I had a smoked house and we re-painted every surface/primed with kilz, replaced carpet and cleaned coil and ducts--- smell was improved, but not gone until we replaced ducts- The air scrubber is a great starting point with a new project - it will remove 90% of the smell before you even paint-Good luck

I can thin set backer and shoot it down with a coil nailer faster than someone can screw it down without thin set and know that my system will be more forgiving to the existing conditions of the floor.

I always install a brass shut-off valve into a wall alcove behind the refrigerator and run a coil of copper tubing from that valve to the refrigerator.

The unit went out 10 months later and he started blaming the tenant and also blamed the evaporator coil in the attic for burning out the compressor.

@Luke BabichWondering why you need to core through the concrete floor... are you intending to install the furnace/evaporator coil in the basement?

Now I ensure the feed line is at least 5ft coiled behind the fridge as you will need a good 3-4 ft of clearance to get behind it if its between base cabinets.

I believe these little coils fit over you mainr feeds.

You air handler may need to have the coil cleaned or the outside Condensing unit may need a good cleaning.

Just choose how you want to live.The concept of tankless sounded great but there is maintenance on the heater coils and, for some models, there is a longer delay in getting hot water out the faucet.

I don't own a roofing coil nailer and am fine if I never do.
