Knowing this job had an attic air handler it should have been rescheduled for a cooler day ( it was 86 outside and probably over 120 in the attic). Should have been 2 people with it being an air handler in case whoever goes into attic passes out from the heat. I have always had 2 guys come out with other companies and they told me that was the reason. Now I don't know what kind of shape my 19 year old air handler is in and I paid for service but only got 1/2 the job done. The worker was very friendly and apologetic but I know my unit doesn't have many years left so was disappointed at not being able to get thorough job done.
