            Complaint Type:
            Guarantee/Warranty Issues
            Status:
            Answered
            I've had about 9 service calls in less than three years (thank God I bought a 3 year warranty). Most of the issues have been labor/installation issues, some mechanical. My system has frozen and flooded three times. The system has also leaked through my attic. I had to purchase space heaters twice now along with a portable AC unit in the summer. My condensation line is more exposed now to the elements (also not insulated) due to an improper fix during the first freeze. Brennan is not accepting any responsibility for their lack of performance. My system is almost out of warranty and I'm stuck with a terrible system again mostly due to improper installation. When I call other HVAC companies to come out and fix it because they can get to me faster than my hired contractor, they refuse to work on it because it could void my warranty with the manufacturer. How many service calls does a customer need to have in three years for them to take accountability that they have failed me?

            I wanted to follow up again on the issue we have been working on. I appreciate your efforts however it seems nothing has happened. That is too bad I am disappointed. This naturally affects Brennan credibility and our decision of where to purchase a new furnace. Again to summarize:The Brennan repair person came out to diagnose and hopefully repair our furnace. It had stopped working for about 6 hours a few days before. Then started working again on its own. I wanted to know why it stopped and if it could be fixed or I needed to replace it.He performed absolutely no diagnostics nor did he take a tool or testing device out. He summarized the error codes I gave him from when it was not working. He talked a great deal and did nothing. He tried to sell me a service plan When he found out ***** had already been out to quote a new furnace he became offended and he was done. By the way the actual issue I hoped he would diagnose and fix was sludge in the water drain thing on the side of furnace. The competent repair tech that caught that actually heard it before removing cover. It has worked great since. I truly and sincerely feel that the money I paid Brennan - $206.99 - for the diagnostics and repair was a waste of money and time. I feel that a refund would be appropriate and deserved. This experience has tainted by impression of Brennan which I once held in high regard.
