"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"Really appreciated the next-day appointment (on a Saturday) and the high quality Service Representative who showed up on time and completed the necessary repair quickly and efficiently. Really excellent service. Would highly recommend Snell Heating & Air Conditioning for any repairs or service. We will definitely call them again if we need any work on our HVAC systems."

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."
