Report
Critical: Punctuality, Quality, Responsiveness, Value They contract with our apartment building. Have had them come out multiple times over 3 years. Unable to diagnose problems, difficult to work with and schedule with. Because they cannot diagnose problems we are without AC for the entire summer while we wait for a replacement part from a new contractors. Do not use.

Report
I would not recommend this company or use them in the future due to the poor customer service received. The technician called out sick and could not reschedule until five days later knowing we had a 2 and 3 year old exposed to the cold environment in the home. Additionally, I did not feel this company did a good job of informing the consumer throughout the process of the cost associated with the repair including the fact that the time associated with driving to the house is considered "labor, " which cost an hour of labor or $125. Additionally, when I called to voice my concerns the business representative, Steven, acted extremely condescending in manner and made erroneous assumptions.

Report
Our office's AC went out yesterday on a particularly hot day in July. I called one of the technicians (Juan Castendas) cell phone directly because they have a service contract with us and he said he was in the area, 1 hour later our AC was back up and running for under $300! It's also a 10 year old unit so it's a wonder they were able to bring it back to life!
