Straight answers for owners, managers, and facility teams

  • Do you offer commercial AC repair in the Peoria area?

    Yes—HilCo provides commercial HVAC service in Peoria, AZ with a focus on light commercial systems. We understand that a down unit can affect customers, employees, and revenue, so we aim to respond quickly and communicate clearly. Our phones are answered live 24/7, so you can reach a real person and get the next step right away. If you need urgent help, tell us what’s happening and we’ll prioritize accordingly.

  • What types of commercial systems do you work on?

    We service common commercial heating and cooling equipment used in offices, retail spaces, and small facilities. That includes rooftop units, packaged systems, split systems, and many standard commercial heating setups. If you’re not sure what you have, that’s normal—we can identify the equipment and talk through options once we’re on site. The goal is to bring the right experience to your specific system, not a one-size approach.

  • Can you help reduce downtime for our store or office?

    Yes—reducing downtime is a big part of commercial work. We’ll communicate a clear plan, prioritize critical situations, and when scheduling allows, we can look at early or after-hours service to minimize disruptions. We also focus on fixing the root cause so you’re not calling again next week for the same issue. For ongoing reliability, a tailored maintenance plan is often the best way to prevent interruptions before they start.

  • Do you offer commercial HVAC maintenance agreements?

    We do, and we can tailor maintenance to your business needs—think scheduled visits, system checks, and practical recommendations based on how your space operates. This is especially helpful for property managers or businesses with multiple units who want fewer surprises. Commercial HVAC maintenance can also help systems run more efficiently and catch wear early, before it becomes a no-cooling emergency. We’ll work with your schedule and help you choose a plan that feels manageable and worthwhile.

  • Are you a good fit for larger industrial HVAC projects?

    Our focus is light commercial HVAC—businesses like offices, retail, restaurants, and small facilities where dependable service and clear communication matter most. If you’re dealing with standard rooftop units, packaged equipment, or typical commercial systems, we’re likely a good fit. If the project is beyond our scope, we’ll be straightforward about that early so you don’t lose time. Either way, you’ll get an honest answer and a clear next step.
