- Environmental considerations – Taking steps towards sustainable cooling practices supports global efforts to combat climate change.
What are common AC mistakes to avoid in summer?
You’ll need to experiment a little to find the best temperature settings that balance both comfort and affordability. Remember that even a small increase in temperature can lead to significant energy savings, so finding the sweet spot where you feel comfortable without excessive cooling is essential. Taking proactive steps to avoid the following common mistakes will ensure you don’t unknowingly compromise the cooling efficiency of your home and incur unnecessary expenses.
Setting the thermostat too low
While arctic-like cooling may feel like the best approach – especially when you first come in from the summer heat on a sweltering day – it often makes leaving again even harder, meaning you’ll struggle to adjust whenever you step outside. Plus, as we’ve already mentioned, the strain on your AC system will significantly increase your energy consumption and utility bills.
Ignoring the humidity factor
An effective HVAC system should dehumidify the air as well as cool it. Neglecting to address high humidity levels results in an uncomfortable, sticky feeling, leading to potential moisture-related issues like mold and mildew growth.
Overlooking regular maintenance
Routine maintenance, like cleaning or replacing air filters and checking refrigerant levels, is essential for optimal performance and energy efficiency. Failure to adequately maintain your AC system can lead to reduced cooling capacity, increased energy consumption, and frequent breakdowns that result in costly repairs.
Factors that can impact your home’s thermostat setting in summer
To ensure the best AC setting in summer, you’ll need to consider the following factors and make thermostat adjustments accordingly to enhance cooling and improve overall efficiency.
Air conditioner’s age
Older units often struggle to cool your home efficiently, requiring longer operating times and lower temperature settings to achieve the desired comfort level.
Regional climate
Hot and humid climates typically require lower temperature settings. Conversely, milder climates usually allow for higher thermostat settings without sacrificing comfort.
Home insulation
Insufficient insulation can result in air leaks, allowing cool air to escape and warm air to enter. The increased demand on your AC system often necessitates lower thermostat settings to compensate.
How much direct sunlight your home receives
The more direct sunlight your home receives, the more it will heat up through the day and the harder your AC system will have to work to maintain a cool and comfortable inside temperature.
Personal preferences
It’s normal for household members to experience temperature differently. So finding a thermostat setting that meets everyone’s needs while being mindful of energy consumption and cost savings can take some trial and error.
Room size and square footage
Larger rooms typically require longer cooling cycles and/or lower temperature settings to ensure comfort, whereas smaller spaces are more economical to cool and keep cool.
Are smart and programmable thermostats worth it?
Experts agree that investing in a smart or programmable thermostat is the best way to optimize energy efficiency because you can set specific temperature schedules to control your indoor environment based on your daily routine. Setting your thermostat to the highest comfortable temperature is good practice because a raise of just a few degrees can significantly reduce your electricity consumption. Advances in technology have revolutionized how we cool and heat our homes. Investing in a programmable thermostat allows you to set automatic heating schedules. Smart thermostat systems go even further by offering even more intuitive solutions.
How they help save energy and maintain comfort

Tips for keeping your home cool during summer
As the summer heat intensifies, implementing effective strategies to improve energy efficiency can make you considerably more comfortable – without having to stress about an obscene energy bill at the end of each month. Here are a few tips for ensuring a more enjoyable living space – even on the hottest summer days.
Utilizing fans and strategic ventilation
Ensure proper airflow by keeping vents unobstructed and using ceiling fans to help circulate cool air. Be sure to position ceiling fans strategically to create cross-ventilation, and take advantage of cooler mornings and evenings by opening windows and allowing fresh air to circulate. Zoning systems that set different temperatures for individual rooms can also be beneficial in optimizing comfort and energy efficiency.
Closing blinds and curtains during the day
This is a simple yet effective way to block out sunlight and prevent heat gain. Window coverings like blinds and curtains block direct sunlight during the hottest parts of the day while still allowing airflow. For the best results, opt for light-colored or reflective window coverings that reflect sunlight away from your windows and reduce the workload on your AC units.
Upgrading your home’s insulation and sealing leaks
Upgrading your insulation – particularly in the attic, walls, and floors – is a great way to improve energy efficiency and prevent your AC system from having to work too hard. Additionally, using weather stripping or caulk to seal gaps and cracks around doors, windows, and vents will enhance HVAC efficiency and reduce energy waste.
Efficient air conditioner usage for summer nights
Using AC in the evening requires a slightly different approach to daytime operation. Once the sun sets, there’s usually a noticeable difference as the ambient temperature drops. So savvy homeowners can optimize their AC settings to minimize energy consumption while still ensuring comfort.
Adjusting temperature settings for evening comfort
When the outdoor temperature drops, you don’t need to ramp down the AC temperature as much to feel cool. By increasing the thermostat by a few degrees in the evening, you can avoid energy usage spikes that result from excessive cooling. Research shows that for every degree you raise the temperature, you can save up to 3% on your cooling costs. So, if you consistently adjust your thermostat at night time during the summer months, you stand to make considerable savings.
The roe of sleep mode in saving energy
Most modern air conditioners come equipped with a sleep mode. Also known as night mode, the sleep function is designed to gradually adjust the temperature setting and fan speed to match your comfort needs while you rest. Activating sleep mode before bedtime ensures a comfortable night’s slumber without overcooling your home or wasting energy.
