I called them out to get an estimate on replacing the [duct] work in my attic due to leakage. James, one of the supervisors, came in approximately an hour or so. While he was here, I informed him I wasn’t getting enough air in some of the rooms upstairs. After he gave me a thorough explanation of what was wrong with my 30 year [duct] work, I still wasn’t ready to commit. He offered to send his technician to do a complementary maintenance check on my A/C and heating system. A few days later, Lance and Fernando came to do the check. They were very nice, courteous, professional and knowledgeable. They totally serviced (cleaned thoroughly) all parts of the furnace and A/C units and explained all that they were doing. My system was in bad shape. While they were here, I mentioned again about my air flow problem. Lance looked in the attic and explain how he could redesign the ducts to have straight passage to each room. I believe I got a great deal, senior discount included. The next day, Michael and Alex came out to install. Again, I was impressed with their knowledge and professionalism for them being very young. I don’t know if the redesign will greatly improve my air flow since we haven’t had to use it yet. Time will tell, but so far I am happy with the company’s service.
