Part 1...Oh where to begin...Albert came out today and checked on my a/c unit that \"died\" and proceeded to tell me that I had three options: 1-pay $2600 for a new compressor PLUS the cost of freon/refrigerant, 2-buy an \"outdoor unit\"??? for $3800 PLUS freon, or 3-buy a brand new unit for $7500 that was miraculously reduced to $5175 after he \"spoke\" to his supervisor who \"authorized\" the price reduction. Oh, the freon was priced at $85/lb where, I learned afterward is usually charged at approx. $50/lb. To me this suggests technicians that work on commissions, or get judged by the amount of sales they produce. I escaped this bogus/dishonest salesmanship and called another company. Search my name for a part 2 review of an honest company that charged me WAY less for a fraction of the work that was actually needed. Shame on you Mast Air!!!
