We Are Honest

Our service technicians at Zion Custom Air are precision experts in residential heating, air conditioning, and ventilation. We are transparent. We do not have "hidden costs," and never complete any work without prior approval. We will inform and educate, if our clients so wish, as to what the issue is, each step needed to perform the required service, and will also provide any necessary tips that may help prevent future issues.  Whether you are looking to install a new humidification system,  maintain your furnace before winter hits,  or repair your air conditioning system, you can trust Zion Custom Air to have the knowledge to get the job done right.

We Take Pride In Our Work

With our meticulous workmanship, Zion Custom Air treats your Palmdale, Santa Clarita, or Lancaster home or business with the utmost of care. Our work is clean, precise, and we never cut corners nor leave any screw unturned. Every part of your home comfort system is thoroughly inspected, maintained, and tested. Our thoroughness aims to find the root cause or predetermining factors that may prevent future issues from arising in your equipment. This is the kind of customized care we provide in order to uphold the highest standards of service.  

We Help You Save Money

Who doesn't love a good deal? We try to find the lowest price for equipment and parts so that we can pass the savings onto our clients. In addition, by performing the job right the first time, we help you save time and money from having someone come out twice for the same issue. Furthermore, we like to offer multiple solutions with varying price points if at all possible in order to keep your costs low to preserve your finances. With Zion Custom Air, you get the absolute best at a price you can afford. 

We Offer The Best Value

We do more for the same rate as other companies. Our customized full-service is the best in the industry. We stay current on all of the latest tools and technology to give the most thorough and comprehensive analysis of your residential HVAC system at no additional cost. By being available for emergency services 24/7, you can be sure that your heating and air conditioning issues will be solved quickly and efficiently. Give us a call first and there'll never be a need to call anyone else.

We Value Every Client

We believe that comfort is not "one size fits all."  This is why we customize our service based on the needs of each individual homeowner in order to build long-lasting relationships. We couldn't do what we do without you. 



My family has been using Steve & Zion Custom Air for many years now and we have never been let down by the quality of work they provide. They provide honest, fair quotes and professional work every time.
