Came to perform maintenance on 2 older systems. The downstairs system was off when I arrived. She said it was blowing hot air. I found that the unit was leaking refrigerant at the coil. The compressor also sounded like it was dying. I recommended to replace both systems. Upstairs system is in dire condition as well. Ended up presenting the customer with system replacement options. She said she wants to one more company before deciding to replace systems. Didn’t collect for maintenance. Need to call to collect.
