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.

We Are Honest

Our HVAC service technicians at Zion Custom Air are precision experts in commercial and residential heating, air conditioning, ventilation, and refrigeration. 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 air conditioning, heating, ventilation, or refrigeration system,  maintain your current systems to prevent future equipment breakdown, or repair an unexpected issue, 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 Lancaster, Palmdale, or Santa Clarita home and 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 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 HVAC 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. Our vehicles are fully stocked; we carry many of the parts needed for most repairs and maintenance of prevalent heating and air conditioning brands. This is so that we can get our clients up and running quickly with very little downtime. 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, bottom-line, and budget. With Zion Custom Air, you get the best at a price you can afford. 

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 commercial or residential heating and air conditioning system at no additional cost. When using Zion Custom Air for service, diagnostic fees are applied towards all repairs performed at the time of visit. By offering 24/7 emergency services, you can be sure that your heating, air conditioning, ventilation, or refrigeration issues will be resolved and repaired quickly and efficiently. Call us first, and you'll never need to call anyone else.

We Offer The Best Value

We believe that comfort is not "one size fits all." Our heating and air conditioning technicians and installers are friendly as well as knowledgeable. This is why we customize our HVAC service based on the needs of each individual home or business owner in order to build long-lasting relationships. Zion Custom Air appreciates your business and treats all of our customers like VIPs. We couldn't do what we do without you.
