Vent! I have been in air conditioner h-e-double hockey sticks since we first turned it on in March. The unit on the right side of the house wouldn't work. We called a/c repairman and the 3rd time they repaired it, they said I needed an electrician. Electrician said I needed a complete new electrical service to the house. When I let him know three weeks later that he would be in a bid process, he refused to bid. Seems he may have misrepresented my problem! Next electrician said I needed a carpenter. Carpenter came and did his work and this week I have had a/c guys out, Monday, Tuesday, and guess what - they'll be back tomorrow. We fixed one unit only to have the upstairs unit go out (fan). I'm tired of meeting strangers at my home and paying them money to fix (or not fix) things. When this one is fixed, I'm going upstairs to sew and I may not come down for a few days! And - fair warning - I may not answer the phone!
