"APJ is such a fantastic company. Mr. AJ is such a dedicated, diligent, and honest worker. He truly went above and beyond to make sure that the AC installation was seamless and pain free. I really felt like he cared about me as a customer, which is not something I can say about other companies. I would definitely recommend this company to anyone who needs HVAC services. I only have positive things to about AJ and APJ HVAC!"

"Very good, almost great. The install team arrived on time, confirmed work order & started the job. In about 4.5 hrs, power was applied & we started to get heat. A quick overview of the HAVC system was given, balance paid all questions answered and there were smiles on most faces. The sales person described the operation of the new HAVC to be quieter than current system and it is. However, the term quieter was not expressed in db difference so a service tech came out and was able to discuss the issue. The whole evolution was a positive event and we will gladly refer Orbit Energy & Power LLC, as a HAVC company that I will work with again."

"As far as I remember it went well. I think they came out pretty quickly. They ended up working for 4 hours with 2 people. It didn't really work that effectively."
