Shane at Alaskan Air checked out my heating systems and yes they are l5 years old, but as far as I'm concerned working perfectly. He gave me several options for cleaning and maintenance which I thought were really costly. You do NOT get any tune up with this, check it out, service. But I really didn't think I would anyway. So I'll just wait till they die and get newer updates models. Although this check up was okay and Shane was really nice, I opted for nothing.
