I had this company at my house for a yearly check up and they recommended me to replace the capacitor at 250 dollar. I did not trust this advice because the system was running fine and now one year later it still is running fine. This years check up done by another company did not result in the advise to replace the capacitor. The thing that bothered me also was they were giving me a 50 discount for a positive Yelp review. The lesson the learn of course is that if the company your researching has a Yelp listing don’t trust it. Yelp is not there for you they are there for the one who pays..
