Learn the ideal thermostat settings to save money during Oklahoma's brutal summers while keeping your home comfortable.
At ARP Heat And Air, we've been helping Oklahoma homeowners with their HVAC needs since 2011. Our owner Charlie brings 14+ years of hands-on experience and is known for giving honest, practical advice — not trying to upsell you on services you don't need.
Summer Settings for Oklahoma
Oklahoma summers regularly push past 100°F, making your thermostat settings critical for both comfort and your electric bill. The Department of Energy recommends setting your thermostat to 78°F when you're home during summer. For every degree you raise it above 72°F, you save about 3% on cooling costs. When you leave for work, bump it up to 85°F or use a programmable thermostat to do it automatically.
Winter Settings for Oklahoma
Oklahoma winters are unpredictable — you might see 60°F one day and an ice storm the next. Set your thermostat to 68°F when you're home and awake during winter. Drop it to 60-62°F while sleeping — most people sleep better in cooler temperatures anyway. If you have a heat pump, avoid setting it back more than 2 degrees at a time, as the system will switch to inefficient auxiliary heat to recover.
Smart Thermostat Benefits
A smart thermostat like Nest, Ecobee, or Honeywell can learn your schedule and adjust automatically. Most homeowners save 10-15% on heating and 15% on cooling costs after installing one. ARP Heat And Air installs all major smart thermostat brands — call us for a quote.

Monthly Setpoint Guide
Oklahoma's climate swings dramatically. Settings that work in July don't work in March. Here's a rough month-by-month target.
January-February: 68-70°F during waking hours, 62-64°F overnight and when away. Humidifier running if dry air is causing static/skin/wood issues.
March: Transitional — set thermostat to "auto" instead of heat-only. Overnight lows in 40s still need heat, but afternoon highs in 70s don't.
April-May: Set to cool mode at 74-76°F. Humidity starts climbing.
June-September: 74-78°F depending on tolerance. Every degree cooler adds roughly 3-5% to your cooling bill.
October: Similar to March — auto mode. Heat on cool mornings, AC on warm afternoons.
November-December: 68-70°F during day, 64-66°F overnight.
Programmable vs smart thermostat savings: Simple programmable thermostats save 8-12% versus always-on. Smart learning thermostats (Nest, Ecobee) save 12-18% by learning your actual patterns. Neither saves anything if you override constantly.
