It is never easy to deal with a buyer who is unwilling to pay for services well done.
Unluckyly, the world is full of individuals who tend to take luck of Heating plus A/C professionals plus other professionals.
In all my life as an Heating plus A/C serviceman, I did not have to encounter such a guy until recently. Surprisingly he was a commercial buyer whose chain of restaurants my buddy and I had service for a whole week. The units in the restaurants had been neglected plus required a lot of cleaning plus repairs to restore the air conditioning to its original status. Sadly, even after helping him get back the unit plus spare him the expense of buying up-to-date Heating plus A/C systems for the weird premises, he wanted to be stubborn about paying us. His excuse was that my buddy and I had not signed any agreement on the amounts, so he would pay what he deemed fit; Being a mature plus experienced Heating plus A/C business with over three decades of experience, I did not have the energy to argue with him. Instead, I asked him to channel the payment through the business plus get feedback directly from the owners. That was a route he was unwilling to follow since he knew it might attract legal penalties. Finally, after a few minutes of push plus shove, he agreed to pay the amount owed. He even apologized for his stubbornness after his workers reported improved airflow plus comfort levels as reported by their clients. It turns out fake Heating plus A/C servicemen had duped him that he only wanted to pay for confirmation.
