Samm's Heathing and Air Conditioning has been servicing my AC and Heather for 10 years or more. The technicians are respectful and knowledgeable, specifically Karl Panyko. Karl is a HVAC Specialist and 9 times out of 10 he is the one who services my AC and Heater which is great because he is familar with my unit. Karl is a complete professional and very effective. He fixes it the first time around--never had to call back for additional help. He is respectful and takes the time to explain what is wrong, options for fixing and price differences. Prices are very reasonable. A great business and Karl P is a great HVAC Specialist!
