well, between these storms, had the annual AC check. Not good. It's losing about 2-3 LBS of R-22 every year. The current system is a Lennox, R-22 with gas furnace, about 4 ton unit, 48K BTU. I've been nursing it along over the years, but I think I may have to take the plunge. Installed in '96. So, current HVAC guy I trust, has been honest with me, quoted a price. 4 ton American Standard Silver Series, replace everything, turn key operation, includes all maintenance for 5 years and 10 warranty on just about everything, for 8543.00 I about had to take a deep breath. I googled that system, and a lot of companies, like down in Houston and Florida are advertising around 3500-4000K installed for that exact same system. Yeah I know, if it's on the internet then it's got to be true. However, I just can't believe there's that much of a difference. Am I not seeing something? Is that maybe a "let me get to your house and then I'll have to add some more to that bill" kind of thing? I can see a 400-800 difference in pricing based on location and some other issues, but over 4K difference in price. Really don't know what to do but get another quote from another dealer, but I'm really leaning towards this American Standard brand. HVAC guy is s American Standard licensed dealer.
