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 Craig in Whitby on Twintech Heating and Cooling

I called Twintech during the Covid 19 crisis because our furnace was broken and it was still very cold during the nights. Dave answered all of my questions by phone but wanted to come have a look but only if our family felt comfortable having someone visit during the uncertainty surrounding the pandemic and was able to attend that very same affternoon.

He was very courteous and informative but most importantly he respected his and our safety by wearing medical gloves in our home and maintaining proper physical distancing. He reviewed the various options of the products that suited our needs going over not only price but quality of workmanship, warrantees and where the product was manufactured which were all important factors in making such a large purchase. You could tell that Dave had been in this industry for a very long time.

The installation was done by a fine young gentleman the very next day and we now have a toasty warm home to ride out this crisis in while humming along at 96% efficiency!

I would recommend this very professional, small family business for anyone in need of HVAC equipment or maintenance.

by Lucy in Markham on Twintech Heating and Cooling

My special thanks to Twintech teams! They had replaced my furnace and A/C, and installed a new humidifier for me 2 weeks ago. Dave, the sales manager, not only provided me with an honest quote on the best HVAC products with best quality and warranties, he also arranged portable heaters for me and sent supporting docs to energy company for energy audit. Above and beyond service!

Greg, Grant, Mitch had worked tirelessly and professionally to perform the HVAC installation. They worked with professional tools, and performed proper measurement readings after installation. They are very patient with all my questions, and very pleasant to communicate.

Great work guys! This company sure knows their products and they stand behind their services. My home comfort level has improved! I am glad that I can support an ethical and honest local family business.

by ddame on Twintech Heating and Cooling

Professional, flexible on price and delivered on time...well done. All you can ask for when getting a new furnace.

by nicole.el.thorn on Twintech Heating and Cooling

The work was done quickly and professionally. Workers were really polite and easy to work with.
Product works great!

by Gary in London on Twintech Heating and Cooling

Furnace broke down on a Wednesday, shopped around for prices and Friday Twintechs name came up from a referral from my wife's work. Called Dave 11 am, he came over around 1 pm. Gave me a very good price, I accepted. The guys were there two hours later to take the old furnace out and install the new one. All finished by 6:30pm. Finally heat.
They were very pleasant and helpful. As a result we are doing our A/C later this year with this company.

by Shawn L in Whitby on Twintech Heating and Cooling

After some extensive research, we settled on Twintech for our new furnace. The service - from Dave's initial visit - through to the installation was absolutely fantastic.

Dave was super-patient with our many questions, did not try to "up-sell" us into buying things we don't need, knowledgeable, friendly and all-around an excellent Advisor.

I've forgotten the names of the installers but they were superb as well. They showed up on-time, did all the work with no mess or intrusion, removed the old furnace and installed the new one in one day; all with no impacts to our day-to-day life.

I cannot recommend Twintech enough, especially over any of 'bigger guys' who tried to sell us a bunch of thing we don't need. Twintech were fantastic and my wife and I are very pleased with our purchase.

by Stephen from Pickering on Twintech Heating and Cooling

From the minute I met Dave and discussed my new furnace needs I knew I was in good hands. He was patient, knowledgeable and very professional through the quotation process.

Grant and Greg did an outstanding job on the install. They did a great job of explaining the defects with my old furnace. The quality of the installation was excellent and the attention to detail was on another level. The old adage “You get what you pay for” couldn’t be more true as I feel I received great value, skilled expertise and high quality customer service. I highly recommend Twintech for all your heating and cooling needs.

by Arthur on Twintech Heating and Cooling

Glad to have found a not-too-big local firm that provided the needed expertise, quality workmanship, and competitive pricing as well. In and out in one day, removed the old units, did a nice job installing all of the new units, and left no debris. Even have a service contract that far outshined the big company offerings. Would definitely recommend them.

by Leriksen on Twintech Heating and Cooling

Appreciated a quick response to my request. Dave and Greg were very professional and made the experience seamless.

by petesalmon938 from Pickering on Twintech Heating and Cooling

Very professional through the entire process. Installation and removel was done on a sloppy winter day, they put down runners on the floors and stairs and when they left, there wasn;t any sign of someone being in our house. Furnace works great as promised.

by Ruth on Twintech Heating and Cooling

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!
