Best Air Duct Repair in San Diego CA

IDEAL put in my original AC/Furnace. They did a great job. After having the AC for about 10 years, there have been some problems as to be expected. I have tried to call them for repairs considering they installed my original unit however the price to come out is outrageous!!!  My AC went out on the hottest day of the year, they said to come out on a Saturday it would cost 200.00 which is there overtime rate and another 300.00 to just diagnose it! I found another company  on YELP who did it for 90.00 and came out on a Saturday. If you need that companies number let me know! IDEAL repair costs are ridiculous!
