Should I Leave Interior Doors Open Or Closed During Heating And Cooling?

Most literature on HVAC systems call on homeowners to seal every hole and crack in the house to prevent air leakage, as this would compromise energy efficiency. Naturally, doors would be closed as well, as they could let a great deal of air escape.

While this advice is based on solid principles, there are other factors at work that should be considered when it comes to heating and cooling, with air pressure being a primary concern.

The Pressure To Stay Cool

With everything sealed up, the pressure inside a room will slowly escalate. This is the natural consequence of continuously pumping a massive volume of air from the outside into a finite space. This can be relieved by opening the door from time to time while the occupant is awake. However, the door would presumably stay closed during bedtime. The pressure may eventually reach the point where additional input from the AC forces air to escape through whatever small openings it can find. Conversely, the rest of the house will experience a negative pressure that would suck in air from the surroundings. Outside air is likely to come from passageways like a furnace flue or a chimney.

This outside air carries with it pollutants that have not been filtered out. In fact, the number of contaminants is likely to be higher because of the way in which they got inside. The humidity and carbon monoxide levels will also spike, possibly causing alarms to set off. The health risks involved have to be taken seriously. Try to feel for incoming drafts near the areas mentioned to see if your house is experiencing this problem. Open the bedroom doors to see it anything changes. The reduced air pressure should stop the house from drawing air through these undesirable pathways.

Possible Remedies

So how does the issue get resolved? Opening the doors would be a good start, but leaving them this way throughout the night may not be feasible to most people. The key thing to remember is that we simply need to increase airflow by a small amount to prevent pressure buildup. Transfer grilles are good candidates for a remedy. They do not compromise privacy and are fairly easy to install.

Heating And Cooling Tips For Your Home

When it comes to maintaining a comfortable temperature in your home during the harsh winter or the heat of the summer useful heating and cooling tips are most welcome. The most basic tip of all is to keep your system maintained. Good maintenance alleviates the need for expansive repairs and limits the problems to simple upkeep and replacement of the typical parts known to experience wear and tear, such as the inexpensive filter.

Starting with the ventilation system, a very important part of your HVAC system; make sure the air ducts are cleaned on a consistent basis. The proper cycling of clean air contributes to the humidity level in your home as well as the control of mold and mildew.

Some other simple tips include the following: always adjust your thermostat to match the weather patterns and have your HVAC serviced regularly. An older unit, 15 years or older, may make you uncomfortable with the thought that it will need to be replaced, but before you jump to conclusions, have it serviced. There may be simple problems hindering its performance. Replace your filters every 60 to 90 days and have it serviced at least once a year by an HVAC professional. Have it inspected before the summer and winter seasons begin to prevent problems during the height of the seasons. Remember safety always comes first. Check the batteries on your detectors yearly; insure smoke and carbon monoxide detectors are up-to-date and test them monthly. If the opportunity presents itself, have a programmable thermostat installed. This will give you greater control over your HVAC system.

By making these simple adjustments in your HVAC’s maintenance, you will add years of life to your system and insure the comfort of your family during extreme weather. Heating and cooling tips have a foundation based in keeping your equipment working at its optimum year round. Once that foundation is established, you can build on that with simple things like maintaining you thermostat at around 68 degrees Fahrenheit throughout the winter months and around 75 degrees during the summer waking hours. By combining all these simple tips, your house will remain comfortable in the harshest of weather.
