I just spent 6 years in residential service/replacement. I got to the point where I was tired of hearing myself saying the same stuff to homeowners. Stuff like "you need to change your filter", "you need to get your equipment maintained so you don't buy flame sensors every 3 years"
It gets frustrating when homeowners lie to you, frustrating to hear the sob stories about other companies.
I just transitioned to commercial about 2 months ago and it is simply the best. The work is steady, the office isn't always calling me in a panic to take more calls all the time, and best of all, no haggling over money anymore. PMs are paid for, installs are billed out and repairs only require a signature.
I'll never look back
