This problem often points to inadequate circulation of warm air. It could be due to blocked vents, a failing HVAC fan, or issues with the furnace itself. Ensure that furniture or drapes are not blocking your vents. Also, check if your furnace's filter is clean, as a dirty filter can restrict airflow.
Listen, if your home isn't properly insulated or professionally sealed, you're already losing heat. Combine that with an insufficient heating system, or even an energy-efficient heater that's hampered by air leaks and poor insulation, and you have the perfect recipe for a continuously cold home.
One of the most common culprits when a heater isn't working efficiently is dirty air filters. These can restrict the flow of heated air into your home. Remember, regular checks and replacements are essential for smooth HVAC system operation.
The colder the outside temperature or the stronger the wind, the greater the amount of heat lost through the walls, windows, doors and roof of your home ('the building fabric'). In general terms an older building will lose proportionately more heat than one built more recently.
It could be a symptom of a problem with your nutrition, red blood cells (anemia), blood vessels, thyroid gland, or the brain's thermostat. Try to note how often it happens, how long it lasts, and if it's getting worse. Your doctor might do some tests to narrow down the cause.
If it's warmer inside your home than it is outdoors, the heat produced by your furnace will find a way to escape your living space. The leakier your home, the more opportunities the heat has to escape. And the more heat that escapes, the less warm and cozy you'll be. Air carries heat.
Your HVAC system isn't sized properly
An HVAC system that's too large for your house will cool your home unevenly. It will only cool some rooms off and then shut off versus cooling down the entire house. On the other hand, an HVAC that is too small will have to work above its capacity to cool down a house.
The second your heater goes out, the temperature inside your home starts to decline. The speed at which it continues to decline depends on several factors, including the age and structure of your home. On average, most homes retain some warmth for about 8 to 12 hours.
Some of the most common thermostat issues include:
The thermostat is broken, not properly level, or dusty. The thermostat needs to be recalibrated. There is loose wiring causing a thermostat issue.
So how fast should a furnace heat a house? On average, once you turn on your furnace, it should take about an hour to increase indoor temperature by 1 degree. Afterwards, it's 45 minutes per degree.
Clean your Air Filters, Vents, and Ducts – A clogged air filter will struggle to meet the thermostat's set temperature since the dirt and debris buildup prevents air from circulating through the vents. And as airflow into living spaces drops, so do comfort levels.
This problem often points to inadequate circulation of warm air. It could be due to blocked vents, a failing HVAC fan, or issues with the furnace itself. Ensure that furniture or drapes are not blocking your vents.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
For many of us, 70 degrees is the ideal indoor temperature, but when it is close to 100 degrees outside, your AC unit will be working quite hard to meet these expectations. Consider setting your thermostat at 75 degrees to 80 degrees in your home if the outside temperature is approaching triple digits.
A dirty air filter can get clogged and reduce air flow through your home's heating system. This means the air your furnace is heating isn't reaching your living spaces and causing your furnace to cycle on more often and work longer while it's on.
Gaps in your home's exterior: Air leaks can make it much harder for your AC to maintain a comfortable temperature. Outside heat can enter your home through gaps, seams, or poorly sealed foundations and attics, forcing your AC to work overtime.
About 35% of the heat will escape through the walls and through gaps, in and around windows and doors, and about 10% of heat will disappear through the floor. Taking action to make sure your home is energy efficient has many benefits.
The most accurate thermographic inspection device is a thermal imaging camera, which produces a 2-dimensional thermal picture of an area showing heat leakage. Spot radiometers and thermal line scanners do not provide the necessary detail for a complete home energy assessment.
Your thermostat will not be able to reach your desired temperature if you have something blocking the vents. Check the vents around your home and make sure you do not have any items such as furniture in the way of your vent's airflow. While you're at it, make sure all of your vents are open.
Your house could be cold due to an old air filter, a faulty furnace, improper insulation, or leaky ductwork. The simple fixes, like replacing an air filter, are relatively easy to complete. However, if the heater itself needs repairs, it's best to call in a professional to take a look and determine the problem.
