APS vs SRP: How Your Utility Provider Affects HVAC Costs in Phoenix
APS and SRP customers experience different HVAC costs. Learn how your utility provider impacts energy usage and cooling expenses.
APS V. SRP: HVAC Costs
Not all Phoenix homeowners pay the same to cool their homes. Whether you’re served by APS or SRP can significantly impact your HVAC operating costs, especially during the summer.
APS and SRP use different pricing structures, including standard rate plans and time-of-use options. Time-of-use plans charge higher rates during peak hours, which often overlap with the hottest parts of the day when AC systems work hardest.
This means two homes with identical HVAC systems can have very different energy bills depending on when cooling occurs. Homes with poor insulation or older systems may see higher peak usage, increasing costs under time-of-use pricing.
Understanding your utility plan is key to managing energy expenses. High-efficiency systems, smart thermostats, and proper airflow can help reduce peak demand and lower overall operating costs.
Before upgrading or replacing your HVAC system, it’s important to consider how efficiency improvements interact with your specific utility plan. Comparing lifetime operating costs — not just upfront pricing — provides a clearer picture of long-term savings.
