The time to open or close your windows can be a definite difference on how comfortable your home is during a hot day in particular. Natural airflow can be used to minimal effect by changing simple time behaviors to eliminate indoor heat accumulation and enhance comfort, which is highly dependent on mechanical cooling systems by many homeowners. This strategy also helps achieve greater efficiency in relation to energy use and can be used in addition to your current HVAC system. Managing the windows properly can reduce the imbalanced indoor temperature without straining the cooling system.
Morning Ventilation
The best time of the day to open the doors and allow the air to come into the house is usually in the morning since at this time of the day the temperature outside the house is lowest. Early opening of windows can enable the cooler air to enter the house replacing the warmer air which accumulated in the house throughout the night. The process assists in adjusting the inside temperatures before the heat of the day just starts to increase. Properly used it can also take the load off systems that would otherwise demand air conditioner repair London Ontario services as they are continually overworked in the peak of summer.
Airflow can also be used to eliminate stale air and moisture that could have formed up as the day goes through morning. This is especially applicable in houses where the HVAC systems have been operating to keep the indoor air in limbo since it makes the indoor environment feel natural and avoids reliance on mechanical cooling.
Afternoon Heat Management

Afternoon is the time of the day that the weather is hottest out-of-doors, and opening windows in the afternoon may oftentimes do just the reverse of what the housewife desires to accomplish. The inflow of warm air in the house may rapidly increase the temperatures indoors and render the living places intolerable. During these hours it is advisable to keep the windows shut so that air that has been cool in the morning is not lost.
At this point of the day, shade, blinds or curtains are more useful in conjunction with ventilation than ventilation on its own. Direct sunlight is also blocked which lowers the amount of heat that passes in and allows your HVAC system to be able to work more efficiently without the continuous cycle. This balance is particularly a concern in homes that do not optimize insulation and sealing in the extreme heat.
Evening Cooling
During the evening, the outdoor temperatures tend to start getting lower once again and this provides another chance to have natural ventilation. By opening the windows now, it permits stored heat in the walls, floors and furniture to escape slowly. This process assists to re-establish the comfort in the house without necessarily having to use mechanical cooling systems.
Evening airflow would also help to improve sleep quality as it keeps the bedroom temperature cooler. When it gets cool, cross ventilation works particularly well, with colder air outside of the house circulating through the house and decreasing the residual heat of the day.
Night Time Closure

After the temperatures level or start increasing once more around dawn, closing windows will assist to keep the cooler air produced throughout the night. This stops warm air in the early morning to be introduced and increases indoor temperatures before the cycle of ventilation recurs. It is a small routine that can drastically help in enhancing comfort patterns in a day to day routine.
This routine will help to maintain a more stable indoor climate and help to avoid undue load on cooling systems. However, in the long run, it will positively influence the durability of your HVAC system and decrease the chances of problems that could lead to a need to select professional services.
An easy yet efficient method of enhancing indoor comfort during the warmer seasons is by controlling your opening and closing of the windows. You can minimize heat and increase air circulation and make living conditions more comfortable without using mechanical cooling but rather harness the natural changes in temperature to work in your favor. Such minor modifications can also help in the long term performance of your HVAC system, as it will help lower unnecessary strain when it comes to peak heat operations.
