Decreased Comfort A dirty air filter restricts airflow through the HVAC system making it harder to reach your desired indoor temperature at an increased cost. Regularly replacing the air filter is essential to ensure optimal airflow to maintain a comfortable indoor environment.
Yes. The answer is yes, definitely. If the air filter is dirty, you will restrict the airflow. If the airflow is restricted, the coils will ice up, and you will not be able to cool your home properly. Of course, there are many factors behind why the air coming out would not be cold and strong.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
If your AC isn't cooling your space as effectively as it once did, or if the airflow seems weaker, a dirty filter could be the culprit. Cleaning it could bring back your AC's cooling power.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Dirty filters can cause many problems, from decreased efficiency to ice build-up. But even if those things don't happen, the debris can still damage the delicate components of your AC unit over time. This will lead to premature wear and tear, which can shorten the lifespan of your system.
When it comes to wondering, will changing the air filter make it cooler, yes. Your system will be better able to maintain an even and comfortable internal home temperature.
Turning off your AC when it's not cooling is more than a precaution; it's a necessary first step in troubleshooting and protecting your system from further damage. By understanding when to perform simple checks and when to call in the experts, you ensure your air conditioner remains a reliable refuge from the heat.
After replacing the filter, you should wait at least 12 hours before running the system. If the AC is still not blowing cold air, it could signify that you have a refrigerant leak, a damaged condenser, or your entire mechanical system needs maintenance.
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
A clogged air filter can cause more harm than good. During the day, your AC should cycle on and off, but a dirty air filter can make those cycles more frequent than they should be. Cycling is not only noisy, but it also wastes energy.
You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours. Going beyond this can negatively affect both your system's health and your home's air quality.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
When the air filter becomes clogged with dust, dirt, and debris, it restricts the airflow passing through the system. This restriction causes the AC unit to work harder, leading to decreased efficiency and reduced cooling capacity. Restricted airflow can even cause the coils to freeze in your outdoor or window unit.
We recommend cleaning your window AC unit every month during the cooling season. Dust the unit's exterior as part of your weekly home cleaning routine. Make sure you replace your home's HVAC filter every 1-3 months to lower dust, dander, and other airborne irritants that could clog your window AC filter.
The filter looks dirty: This is simple but effective – look at your air filter. If it looks dirty, dusty, or has clumps of hair and dust, it's time to change it. Allergy symptoms worsen: If you or someone in your home suffers from allergies or asthma, dirty air filters can make their symptoms worse than normal.
Filters with a MERV rating of 1 to 7 typically cost between $5 and $20. Filters with ratings of 8 to 13 can cost anywhere from $20 to $150. HVAC systems in residential homes usually don't need (and often cannot handle) filters with a MERV rating of more than 13.
While an air conditioner should normally cycle on when it senses an increase in temperature, and off when it has sufficiently cooled the room off, short cycles can occur when you have a dirty air filter.
Not only can regularly changing your AC filter help improve your home's air quality and conditions, it can save you money over time. Replacing a dirty, clogged filter with a new, clean one can lower your air conditioner's energy consumption by 5 to 15 percent, according to the US Department of Energy.
What happens if your HVAC filter is dirty? A dirty HVAC filter restricts airflow, which can lead to poor system efficiency, increased energy costs, and wear and tear on the unit.
