    Jake and his partner were wonderful. They explained everything and was on time for the appointment and finished before expected. They put on booties and laid down runners to protect the house from debris. They did an excellent job.

    Khalij came today to do my annual air conditioning checkup. He arrived early and got to work right away. Khalij checked the entire unit inside, the outside unit and thermostat. He reported that everything is working properly. He showed me the outside condenser and how the coils had dust and debris covering them. I remembered it was recommended that I use a hose on it but I never did. So, after seeing it, I asked Khalij if he could clean it and of course he could. He also took the time to explain the thermostat to me and also adjusted it for me. I appreciated how helpful and understanding he was. Khalij is friendly, polite and knowledgeable. I noticed how efficiently the air conditioning is working on this hot day.
