Happy camper here! We weren't getting cool air in the house. Another company told us to replace the unit, the bid was almost $10,000. My husband was referred to Shaffer & Sons. Their tech came out, gave all the equipment a thorough go over and a leak test, replaced the coolant and we have AC again. Easy peasy. Fast service, polite and thorough tech and results! We have a new AC company! Thank you, Thank you!
