When we bought our house Feb of 2016, we couldn't turn on the air conditioning unit because it was too cold outside. The unit worked ok during that summer but definitely struggled to keep up. This summer was even harder. We have the equalizer plan but our unit was constantly running and couldn't even maintain an 80° ambient temp. We called LJ Refrigeration on Tuesday afternoon. I hoped that we could get squeezed in for a diagnostic check up the following week. I was completely surprised to get a 7:00 am appointment the following day!! They were efficient and very informative. They gave us tips on maintaining our unit through monsoon season as well as a regular mantinence schedule. Their price was more than reasonable and within minutes of the diagnostic my house was noticeably better. The unit runs less and keeps the house right where we set it! I will absolutely be recommending LJ Refrigeration to anyone who asks!
