★★★★★
I called about moving an air pump and Brennan Air were out within an hour to look at the job.
They gave me advice on what I could do as another option, even though that advice probably means they will not be doing work for me.
Professional. personable, honest. I will remember and use Brennan when I need to.

Nice to actually have a tradesperson turn up when they say they will  - on time. Very friendly. Great  advice. Said I only needed a good split system when  I was happy to go with  something more expensive they told me I did not need to spend that much. They were right. Thanks again. Good Job
