Need help with what to do with my expensive but poor HVAC install

[Timothy G Dunson]

Good morning all,

I recently bought and renovated a house. With that renovation came a new air conditioner and insulation in the attic to help ensure the AC would work properly. In all I spent 11k on it 7 for the insulation and 4 for the new AC unit.

Since then I've had numerous problems with the unit not working well or at all. I've had it serviced for a frozen coil twice, the overflow has turned it off multiple times and in general will not keep the house below 78° during the day. I feel like I paid enough money for it to work flawlessly year around but has been nothing but problems which is really inconvenient because I run the unit as an Airbnb. Also installed a Google nest so the client's can't turn the air too low.

My question is what can I do with the contractor that installed the unit? At this point I either want a new unit or someone else to do another install because the this one is not doing the job I expected when I paid $11000+.

Thanks for the input as always BP!
