I was unsure what time I could expect Chris. Within a short space of time I received a call, he had attended an emergency. And he arrived as indicated. The work was not an emergency, just a follow up of parts he required to finsh the job. Two Jobs actually, both completed satisfactorily and within the quote previously given. Another well-satisfied customer. I tentatively asked about next years maintenance and was told his software would email in advance reminding me to make contact for a scheduled date. Sounded a good system to me.
