Actually, I'm picking based primarily on service and secondly on price. I didn't pick the lowest guy - I went w/ the company that at least SOUNDED like they would give me the best service - now and down the road... They are big in this area (30 years), and they came recommended by my electrician friend who is doing all of the work.
They were one of the first out here, they didn't try to "sell" me on anything, they had lower pricing on the extended warranty (which - is big to me - because as it's a Trane x warranty, they all have the same price - so - charging $100 and $200 more is just robbery), they won't charge me down the road for emergency / weekend service (the others were going to charge me because Trane only reimburses them for 'regular' time), they included the new disconnect in their price - where as the others wanted me to pay to have my electrician do it when they heard he was putting in the new panel (he'll still be doing it, but it will be covered in their price, rather than me spending another $75 - $150 - however much it is...), and they have answered all of my questions in . what sounded like truthful responses - again not just someone trying to "sell" me..
For example, when I went to them about cleaning the lines vs replacing them - they again explained how they follow Trane's procedure for cleanging the lines, BUT, said that if I would be more comfortable w/ them replacing the lines, they would do it - and will not be charging me for it. They also took a few dollars ($35) off because I had recently installed a new Honeywell Thermostat - which had more features in it than what they were going to install, so - they just took it off... things like that.
There were a few other things that they did that made me go their route
- it was all about the SERVICE - at least "pre-sale" has been great! I'm hoping it will continue.
We'll find out today... They're coming out to do the install... for the 14XLi. My electrician is also installing my new panel today - going from 150 aluminum wiring to 200 amp and copper.
