Real Customer Story: How Day & Night Saved a Phoenix Family
In July 2024, the Martinez family in Ahwatukee woke to a completely dead AC during a 115°F heatwave. Their 12-year-old unit had a failed compressor. After being quoted $8,500 by another company for a replacement, they called Day & Night.
Within 90 minutes, a technician arrived, diagnosed the issue, and offered two options:
- Repair with a used compressor: $1,200 (3-month warranty)
- Replace with a new 16 SEER2 heat pump: $6,200 (10-year parts + 5-year labor warranty)
They chose the replacement. The team installed it the same day, added a smart thermostat, and showed them how to monitor energy use via an app. Their August electric bill dropped by 22% compared to the previous year.
“They treated us like family—not a ticket number,” said Maria Martinez. “Worth every penny.”
Understanding HVAC Efficiency: SEER2, HSPF2 & Why It Matters
Since 2023, all new AC units must meet SEER2 standards (Seasonal Energy Efficiency Ratio 2), which account for real-world duct losses and static pressure. Similarly, HSPF2 measures heating efficiency for heat pumps.
- Old standard (SEER): Tested in ideal lab conditions
- New standard (SEER2): Reflects actual Phoenix home performance
Choosing a SEER2 16+ unit may cost more upfront but pays off in lower bills and fewer repairs. Day & Night helps customers calculate lifetime ROI using utility rate data from APS (Arizona Public Service).

Step-by-Step: What to Do When Your AC Breaks in Phoenix
If your system fails, follow these steps before calling a technician:
- Check the thermostat – Ensure it’s set to “Cool” and temperature is below room temp.
- Inspect the circuit breaker – Reset if tripped (but don’t reset repeatedly—this indicates a serious fault).
- Clear debris – Remove leaves, dirt, or pet hair from outdoor condenser unit (maintain 2 ft clearance).
- Replace air filter – Use a MERV 8–11 filter; dirty filters cause 30% of AC failures (EPA).
- Call Day & Night – Mention any error codes (e.g., “F1” or “E4”) for faster diagnosis.
Never pour water on your condenser to “cool it down”—this can cause electrical shorts or compressor damage.
