How to Read Your APS or SRP Electric Bill in Arizona
Use your own bill to identify the rate plan, billing period, energy use, and any demand-related information. Then use the utility’s current resources before making a plan change or treating an HVAC decision as a guaranteed bill-saving fix.
Read your bill in order
Four checks before drawing conclusions from a high bill
Start with the service period and plan
Find the billing dates, total kWh, amount due, and your plan name. The plan is essential context before comparing one month with another.
Compare usage before comparing dollars
Use the bill’s history or comparison section to see whether daily kWh changed versus the prior period or the same month last year. Weather, household routines, and equipment use can all affect the comparison.
Separate kWh from kW
kWh measures energy used over time. kW measures the rate of demand. A demand-based plan may show a demand figure or charge in addition to energy use.
Check the utility’s current plan guidance
Do not rely on an old table or a neighbor’s plan. APS and SRP publish current rate-plan information and account tools for their customers.

Start with system condition, not a promised savings number.
A bill alone cannot diagnose an HVAC system or predict the result of a repair or replacement. If you are seeing a comfort symptom, Bradford can document the system condition and explain the next practical step. For a new-system decision, compare the selected equipment, installed scope, coverage, and payment disclosure in writing.
Common questions
Answers without guessing at your bill
Where do I find my APS or SRP rate plan?
Look in the customer or account information area of your bill. Both utilities also provide account tools and current plan information. Confirm the plan directly with your utility before changing it.
What is the difference between kWh and kW on an electric bill?
kWh is the amount of electricity used over time. kW is the rate at which electricity is being used. A demand-based plan can include a demand measure or charge in addition to energy use.
Can Bradford tell me which APS or SRP plan to choose?
Bradford can discuss an HVAC diagnosis, maintenance finding, or replacement scope. APS and SRP control their plans and rates, so use the utility’s current comparison tools or customer support to make a plan decision.
Will an HVAC repair, tune-up, or replacement guarantee a lower bill?
No. Utility bills depend on the rate plan, weather, thermostat use, home conditions, and many other factors. A diagnosis or tune-up can document system condition; a replacement comparison should focus on the exact equipment and installed scope for the home.

Need a documented system check?
Review the tune-up scope and decide whether maintenance is the right next step for your system. Utility bills and results vary; Bradford will explain the documented condition before you approve additional work.
