Optimal Usage of Your AC Unit

Optimal Usage of Your AC Unit

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

  1. 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.


  2. Use Ventilation Wisely: Use exhaust fans in kitchens and bathrooms to remove heat and humidity from cooking and showers.


  3. 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.

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

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!!

by Courtney Parkes on Twintech Heating and Cooling

Just hired TwinTech Heating & Cooling to do an A/C Unit removal & reinstall to allow for landscaping access on the side of my house, and they were wonderful!
Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
I would highly recommend them for all of your HVAC needs! Great job guys!!

by Jacqueline Graham on Twintech Heating and Cooling

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!

by Bill Grainger on Twintech Heating and Cooling

Just had a new furnace installed by Twintech. I can’t express how great these guys are at what they do. From the sales to installation they were professional all the way. Very reasonable pricing and courteous during the installation and willing to answer any questions I had. Highly recommended !!!

by Colin Vernon on Twintech Heating and Cooling

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.

There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

by Heidi B on Twintech Heating and Cooling

Bob and Greg made us feel comfortable withe process through their thorough explanation and knowledge of the right furnace for our needs. The professionalism and courteous friendly attitude towards the customer is what we liked the most as they treated us like family. So happy with our decision and new furnace we will be looking into get our rental water heater replaced and installed by Twintech team. We feel better having their knowledge on our side and will only trust them with any further maintenance of furnace.

by Kirushanth Rasiah on Twintech Heating and Cooling

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

by Leonard Glass on Twintech Heating and Cooling

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.
