Arizona summers don’t just sizzle—they scorch. When highs flirt with 110°F for weeks, your air conditioner becomes both hero and hostage. Push it too hard, and you’ll be paying for an emergency repair faster than you can say “monsoon season.” Below are field-tested tips from the technicians at Gladiate Air Conditioning & Heating that help keep customers comfortable and prevent premature system breakdowns.
1. Find the thermostat “Goldilocks zone”
Set your thermostat around 78 °F–80 °F when you’re home and bump it up to 83 °F–85 °F when you’re away. Every degree above 80 °F can shave 2–3 % off your cooling bill—and keep the compressor from running nonstop. (SRPconnect Blog, aps)
Pro tip: Cranking the stat down to 70 °F won’t cool rooms faster; it only forces the unit to run longer and harder.
2. Let your utility do the heavy lifting
Both APS and SRP reward customers who pre-cool during off-peak hours and then coast through the afternoon heat. Pair a smart thermostat with their programs, and you can earn bill credits while your AC cycles less during the 3 p.m.–7 p.m. price spike. (aps, aps)
3. Block the heat before it sneaks in
- Close south- and west-facing blinds by 10 a.m.
- Add reflective window film or solar screens.
- Check attic insulation—R-38 is the baseline for homes in desert areas.
Stopping radiant heat lowers indoor temps up to 10 °F, so your AC doesn’t have to.
4. Change (or wash) your air filter every 30 days
A clogged filter can reduce airflow by 15%—the fastest way to overheat a compressor. Set a calendar reminder or join Gladiate Air’s Care Program; we swap filters during each seasonal tune-up so you don’t have to remember.
5. Keep air moving
Run ceiling fans counterclockwise so they push cool air down. Fans don’t lower room temperature, but they let you raise the stat 2–3 °F while feeling just as comfortable—big energy win.
6. Give the outdoor unit breathing room
Clear weeds, gravel, or pool toys at least two feet around the condenser. Restricted airflow makes head pressures spike and can trigger emergency shut-offs on the hottest afternoons.
7. Time your heat-making chores
Dry laundry and run the dishwasher before 10 a.m. or after 8 p.m. Ovens and stovetops can increase the temperature in the kitchen by two degrees; consider using the grill instead.
8. Schedule a professional tune-up—now
A preseason inspection:
- Checks refrigerant charge and superheat
- Tests capacitors/relays under load
- Cleans evaporator & condenser coils
- Verifies static pressure in ductwork
Catching a weak capacitor or low charge in May is far cheaper than replacing a fried compressor in July. Gladiate Air technicians bundle all of this into our Summer Cooling System Check (part of the Gladiate Care Program).
9. Consider strategic upgrades
- Variable-speed or inverter heat pumps deliver the same cooling at 30 % less energy.
- Duct sealing & zoning fix the “ice‐box main bedroom, sauna living room” problem.
- Attic radiant barriers reduce attic temperatures by 20 °F or more, easing duct heat gain.
Local utility rebates often offset a chunk of the cost—ask us what’s active this season.
10. Know when to call in the cavalry
If you hear grinding, smell an electrical odor, or your indoor coil ices over shut the system off and call Gladiate Air. Running an injured unit can destroy the compressor in hours.
