"We are consistently looking for ways to develop our employees knowledge and we make sure our customers get treated fairly." - ADINSSON SALAZAR

While today's AJ's Heating and Air Conditioning, LLC is a thriving and rapidly growing business within the Washington D.C. Metropolitan Region, the company began life simply as one man's dream. After spending years learning the in's and out's of the heating and air conditioning industry at large companies, Adinsson Salazar decided to take the leap into entrepreneurship and found his own AJ's Heating and Air Conditioning on June 23, 2016.

Adinsson's honest, educated approach to HVAC installation and repair quickly won him fans and the company has flourished under a steady stream of client referrals. This has allowed the company to bring on additional HVAC technicians and grow into a force within the Region.

AJ's is known for its honest, ethical approach to business coupled with a deep understanding of the HVAC world. Each AJ's employee appreciates the company's customers and treats them with deep respect. We care about our customers' problems and strive to help find solutions quickly and as affordable as possible. We never treat our customers as dollar signs, and they reward us by referring our services many times over.

Education is important to Adinsson, which is why we are consistently looking for ways to develop our employees' knowledge. Seeking out and obtaining certifications, Continuing Education (CE), and participating in industry organizations are an important part of the AJ's culture.

We begin with a conversation.

Our work on your HVAC problem begins from the moment we say "hello" on the phone. We take the time to understand your needs before quickly sending one of our certified HVAC technicians to meet with you in person.

We conduct the work

Once we've evaluated your HVAC needs, we will create a written proposal that spells out all of the work and associated costs. While we source quality parts and systems, we do our best to save you money at every turn.

Satisfaction is guaranteed

AJ's stands behind our work! We are confident in our technicians' work and offer a guarantee on all of our work. This guarantee will be spelled out in your AJ's service agreement.
