came out to a no cool on a 2006 R22. The customer stated that he had someone out yesterday to work on his equipment. I found that the thermostat was not installed properly and that the out door unit was also not installed properly. I explained to the customer that i will need to rewire everything and charge a fee to do so and they declined. I also explain to the the age and type of equipment that they have is now obsolete and it’s a good time to start looking into a n replacement system. I set up a lead with the customer to get a quote on a new system.
