Optimal Usage of Your AC Unit
Posted On: May 31, 2024
Optimizing the usage of your AC unit can help extend its lifespan, improve efficiency, and lower energy costs. Here are several tips for achieving optimal usage:
1. Set an Appropriate Temperature
- Summer Settings: The ideal temperature range is typically between 24°C (75°F) and 26°C (78°F). Every degree below 26°C (78°F) can increase energy consumption by 6-8%.
- Night Settings: Raise the temperature at night when it’s cooler outside, or use a sleep mode if your AC unit has one.
2. Use Programmable Thermostats
- Schedule Cooling: Set your thermostat to higher temperatures when you’re away and lower it shortly before you return.
- Zoning Systems: Use programmable or smart thermostats to create cooling zones, only cooling the areas that are in use.
3. Enhance Airflow
- Ceiling Fans: Use ceiling fans to circulate cool air, allowing you to set the thermostat a few degrees higher.
- Unblock Vents: Make sure vents and registers are not obstructed by furniture, curtains, or other objects.
4. Regular Maintenance
- Change Filters: Replace or clean air filters every 1-3 months to maintain proper airflow.
- Clean Coils: Clean the evaporator and condenser coils annually to ensure efficient heat exchange.
- Check Refrigerant Levels: Ensure that the refrigerant level is adequate, as low levels can reduce efficiency.
5. Seal and Insulate
- Seal Leaks: Seal windows, doors, and any gaps in your home’s envelope to prevent cool air from escaping.
- Insulate: Improve insulation in your attic, walls, and ductwork to maintain a consistent indoor temperature.
6. Shade Your Unit
- Outdoor Unit: Provide shade for the outdoor unit without obstructing airflow. A shaded unit can be up to 10% more efficient.
- Indoor Blinds and Curtains: Use blinds, curtains, or shades to block direct sunlight and reduce the cooling load.
7. Reduce Internal Heat Gain
- Appliances: Use heat-generating appliances (like ovens and dryers) during cooler parts of the day.
- Lighting: Switch to energy-efficient lighting options, such as LED bulbs, which produce less heat.
8. Upgrade Equipment
- Energy-Efficient Units: Consider upgrading to an ENERGY STAR-rated AC unit for better efficiency.
- Right Size: Ensure that your AC unit is properly sized for your home. An HVAC professional can perform a load calculation to determine the appropriate size.
9. Use Dehumidifiers
- Reduce Humidity: In humid climates, use a dehumidifier to reduce the moisture in the air, which can make the indoor environment feel cooler and reduce the load on the AC.
10. Monitor and Adjust
- Track Performance: Monitor your energy usage and adjust settings as needed to maintain efficiency.
- Professional Inspections: Schedule regular professional inspections to identify and address any potential issues before they become major problems.
Additional Tips for Optimal AC Usage
-
Keep Doors and Windows Closed: Ensure all doors and windows are closed when the AC is running to prevent cool air from escaping and warm air from entering.
-
Use Ventilation Wisely: Use exhaust fans in kitchens and bathrooms to remove heat and humidity from cooking and showers.
-
Automate with Smart Systems: Integrate your AC unit with a home automation system to optimize performance based on occupancy and outdoor weather conditions.
By following these tips, you can ensure that your AC unit operates efficiently, providing you with a comfortable indoor environment while saving energy and reducing operational costs.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
