Common questions

Straight answers to help you choose the right next step

  • What residential HVAC services does HilCo offer?

    We cover the full range of home comfort needs, including AC repair, AC installation and replacement, heating repair and installation, tune-ups, ductless mini-splits, and indoor air quality improvements. We also offer duct cleaning, dryer vent cleaning, and water heater service for homeowners who want one trusted partner. If you’re unsure where your issue fits, we’ll help you narrow it down with a clear explanation. The goal is to make it easy to get the right service without feeling overwhelmed.

  • Can one company handle all my home AC needs?

    Yes—many homeowners use us for everything from emergency repairs to new system installs and ongoing upkeep. We service all major brands and focus on what’s best for your home, not what’s easiest to sell. If your system can be repaired responsibly, we’ll lead with that conversation first. And when replacement is the better long-term choice, we’ll explain why in a way that actually makes sense.

  • How do I know if I need a repair or a replacement?

    Start with symptoms and history: frequent breakdowns, poor cooling, rising energy use, and uneven temperatures can point to either a fixable issue or a system that’s nearing the end of its useful life. We’ll inspect the system, talk through what we find, and give you options with pros and cons—without pressure. Sometimes a targeted repair is the smartest path. Other times, replacement saves you money and stress over the next few seasons.

  • Do you offer HVAC maintenance for home systems?

    We do, and it’s one of the best ways to reduce surprise breakdowns—especially before peak summer heat. A proper tune-up helps catch worn parts, airflow problems, and performance issues early. We also offer our Energy Savings Agreement on the Maintenance Plans page, which is designed for homeowners who want consistent care year-round. If you’re not sure what schedule makes sense, we’ll recommend a simple plan based on your system and usage.

  • Do you serve areas outside Peoria?

    Yes—while we’re based in Peoria, we serve homeowners across the Northwest Valley and surrounding communities. That includes nearby areas like Glendale, Surprise, Phoenix, Sun City, and Sun City West. If you’re not sure whether you’re in our service area, the fastest way to confirm is to call or text. We’ll let you know what we can do and how soon we can get there.
