On Monday September 14, 2015, I spoke with the Director of Residential Sales regarding the need to replace my unit that went out on Saturday. Within 30 minutes he was at my door ready to help me through the process of replacing the unit. After looking at my existing unit, he thoroughly explained my options. He was courteous, knowledgeable and happy to explain the nuances between the different types and the costs of same which provided me with the peace of mind that I was making a wise decision. At no time did I feel pressured to go above my price point or make a decision I was not comfortable with. The next morning about 8:00 a.m. the installers/technicians were at my home and ready to go. This was impressive since I requested they be there by 8:30 and had only made the initial call 24 hours prior. The technicians were polite and well equipped. They cleaned up after themselves, took the time to explain anything I asked and made sure I was happy before they left. I humbly write this review in appreciation for the outstanding service I received and with the intention of being useful to people who come along after me. Whether you are in need of service or maintenance to an existing unit or in need of a new unit I strongly recommend this company. An A/C can be an expensive purchase for many homeowners and it is imperative that the company have the excellent standards that Armstrong demonstrates.
