I am building a house. I signed a contract to have an air condition installed. The contract specifically stated that it was a RUUD unit. Two day later the air condition company wanted to install a unit sub standard to what was agreed and signed to. I told him no. Then one day letter a request for 900 more dollars was asked that he underbid the contract. i told him no. Everything was quiet for one week. I now get a letter saying he is placing a lien for 8300 dollars on my home. He said that he already bought the equipement. The company never installed it or even brought it on the property.
