A warning alert popped up on our indoor A/C thermostat on June 16th. We called Freedom A/C and they sent a tech out to check it out on Friday, June 17th. He did an outdoor system flush on our unit with our garden hose and some foam cleaning agent he brought. After being outside for 30 minutes and making multiple phone calls outside, he came in the house and wanted to tell my husband and I the bad news. We were low on freon and needed a new capacitor and 4 lbs of freon, which would be about $600. He said we could schedule that work but it would only be a temporary fix due to the leak, and we might be better off just buying a whole new A/C system from them. My husband and I thought about it over the weekend and figured that even leaks can be fixed and the air coming out of our vents was cold and forceful. Our Lennox A/C unit is only 10 yrs old. Many A/C units last anywhere from 16 to 20 years with proper maintenance. The only problem area was in our living room where we have a cathedral 20 foot ceiling and 2 skylights. It had been in the 90s. We called Hartman Brothers A/C out of New Haven, IN bc they were listed under "more info" on our wall thermostat. They sold the prior homeowner the Lennox A/C unit we have. A technician came out today and confirmed that we DO NOT have a freon leak, that our unit is still fine. Nick, the tech from Hartman Brothers said in higher temps a cathedral ceiling room with 2 skylights is not going to remain ice cold. Our unit only needed a good cleaning, a new filter ( which we are ordering on Amazon), and some register boosters, which you put on floor vents to push the cold air up with little fans built inside the register booster. Nick said we can order them on Amazon too. Now we only owe a service visit to the honest company, Hartman Brothers, which we will be using from here on out. Second opinions before buying a whole new A/C system are a good idea. read more
