This company gets our very highest recomendation. They truly demonstrate a commitmant to excellence and customer service. We recently had a most unusual problem with our furnace and propane fuel supply line that Bobby Thiry and David Pratt of Kahl HVAC would not give up on until they solved the problem …which they did! We are so pleased to have found this professional company with seasoned technicians committed to customer satisfaction. Very reasonable prices and 5 star service! We highly recommend them.
