Did nothing but lie and try to sell me on buying a new a new, overpriced furnace. I paid to have him fix the furnace, but rather than doing the fix (my kids had placed rocks in the outdoor pipes) he told me I needed a new furnace based on CO levels. Mind you, he never actually tested the CO, nor would it be possible to ignite the furnace to determine this.

In the end I removed the rocks myself and will be going with a more honest installer. Sleezy all the way. Avoid.

Update: in regards to Mr. Barfield s response, I would like to provide the following input as a consumer of their services. While you note poor condition of flames and that the heat exchanger was in poor or questionable condition, I must strongly attest that these are quite subjective analyses and thus very much a judgement call for the technician. He immediately jumped to the conclusion that a new furnace was warranted without entertaining or suggesting the idea that a fix was possible. I never requested a quote for a new furnace in lieu of repairs; repairs were simply never offered.

Is it really enough to warrant an immediate jump to this conclusion without hard, QUANTITATIVE assessment (i.e. an actual CO measurement)? People appreciate proof, not speculation. There is simply no excuse for the technician to not take a CO test to validate his speculation.

UPDATE 2: Another HVAC technician came and cleaned out the burners, flushed the water lines (there was gunk in them) and was able to ignite the furnace and take CO levels. Not even CLOSE to having high CO levels - 7 PPM directly from the furnace. This company obviously did nothing but try to sell me on a completely unnecessary new furnace. Oh yeah - I also got a quote from another company for HALF THE PRICE! Terrible technician that reflects horribly on the company.
