In mid-October 2015, we met with Carlos Jimenez the Vice President/General Manager of Air Systems to discuss options to repair or replace our existing home AC heating unit. Upon meeting Carlos, he was knowledgeable, professional and honest. Within a day after the first meeting, Carlos submitted a Proposal that outlined multiple options for repair or replacement. Each option in the Proposal was thorough and was explained in detail very well. Air Systems' costs were much better than competitors' prices. Once we made the decision to hire Air Systems, they visited our home job site the day before the installation to do a site survey to make sure they had all the materials needed for the project. They were very thorough - job done right from the start! The workers left the work area in the attic cleaner than it was. We decided to go with the most energy efficient Trane unit to cut energy consumption as well as reduce noise. The heating venting ac unit has proved to be one of the best investments we've made for our 10-year old home. The only time we know that the unit is running is when the house gets cooler or warmer. Silent operation both inside and outside. The thermostat is simple to use and is informative. It shows the outdoor temps, indoor humidity, when to replace the filters, etc. Carlos was honest, fair, professional, knowledgeable, prompt, and not pushy. Valuable assets and a rare combination for contractors in this area. We will be using Air Systems in the future for all our HVAC needs.
