How to Lower Your TEP Bill: HVAC Tips for Tucson

TEP (Tucson Electric Power) rates are climbing. Here is how to fight back with HVAC efficiency. These are the tips that actually move the needle.

1. Smart Thermostat Programming

TEP peak rate hours are typically 3-7 PM in summer. Program your thermostat to pre-cool your home to 72 degrees before 3 PM, set to 78 degrees during peak hours, then return to comfort after 7 PM.

“Pre-cooling before peak hours is the single most effective thing most Tucson homeowners can do right now. Savings: 10-15% on cooling costs.”

2. Seal Your Ductwork

Older Tucson homes lose 20-30% of cooled air through leaky ducts. Professional duct sealing with mastic can recover most of this loss. Savings: 15-25% on HVAC costs.

3. Change Filters Regularly

In Tucson's dusty environment, change filters every 4-6 weeks during peak season. A clogged filter can increase energy use by 15%. Savings: 5-15% on cooling costs.

4. Professional Maintenance

Annual maintenance keeps your system running at peak efficiency. Dirty coils, low refrigerant, and worn components all waste energy. Savings: 10-20% on energy costs plus fewer breakdowns.

5. Upgrade to Variable Speed

Variable speed ACs run at lower capacity most of the time, using less energy and providing more consistent comfort. Savings: 20-30% compared to single-stage systems.
