"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."

Energy Efficiency Auditing FAQs, answered by experts

Common warning signs of an overloaded electrical panel or meter box include frequent circuit breaker tripping, flickering or dimming lights, scorch or burn marks, and a burning scent coming from the panel. A circuit breaker trips as a protective measure to prevent overheating and potential fires. If you observe any of these signs, turn off the affected circuit breaker and move some devices to a different circuit. If the problem persists after turning the breaker back on, you should contact a professional electrician to resolve the issue.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.
