The level of customer service at this company is amazing. The staff is responsive and considerate. The AC┬átune-up Phoenix technicians are extremely knowledgeable and think outside the box when it comes to troubleshooting…especially in old houses – Jeff has been amazing. I am so grateful to have found a reliable, honest, and efficient company to work with. AC is a must in AZ and I have no compunction in recommending LJ Refrigeration.
