Very Knowledgeable
The A/C Tech was very knowledgeable and professional. He was very informative as he was trouble shooting the various problems I was experiencing with my A/C. He gave me the best case and worse case scenarios and how much each would cost. He informed me about the average life expectancy of the A/C and the costs involved with replacing the unit.
A Wonderful Experience
My grandmother had a wonderful experience with Stewart Heating Plumbing Air Conditioning. Jamie J. was our service technician. His work is thorough and efficient! He helped my grandmother understand the functions of the system and answered her frequently asked questions. She said his work ethic was great!
Service is Impeccable
Stewart's service is impeccable. From calling and setting up the appointment, to a technician who was prompt, courteous and very professional. My original request for a tune up really should have started as a service call (my mistake). But Eric had no trouble pivoting, diagnosing the cause, and solving the problem very quickly. He explained all the diagnostic steps, the solution, and proved system was working correctly! A great job from beginning to end!
