Dirty Air Filters
When your air filters get dirty, air cannot flow through them as easily. Which means your furnace has to work harder to get you the air. A few signs of dirty air filters are an increase in energy consumption, less airflow, and bad indoor air quality. Replacing your air filters can help clean the air, reduce allergens, improve energy efficiency, and extend the life of your furnace. Checking and replacing your air filters is a crucial part of the maintenance of your furnace.
Having improper airflow could cause problems with your furnace. You want to get regular cleaning done on your air events, air ducts, and registers. You do not want any debris blocking your air because it can hinder the amount of airflow going into your home. Having proper airflow can increase the efficiency of your furnace. It is important to clean and get regular maintenance on your furnace so that they can check if there are any leaks or damages to your air ducts.
Clogged HVAC Drain Line
If you have clogged drain lines, then it will back up your water and start to cause damage to the furnace and the area around the furnace. It is important that you clean your drain line so that it does not become clogged. A great way to do this is to use a vinegar/water mixture and this will help get rid of the debris and buildup in your drain line. If the water cannot drain, it can start to cause problems with your furnace.
Dirty Blower Motor
When you have a dirty blower motor, it can weaken the air flow to the vents. Regular cleaning of the motor can prevent any issues from occurring. It is very important that you clean the blower motor so that it does not get any dirt and debris around it over time. It is best to hire a professional to come do it but you can use a soft brush and gently clean around the blades and fins to get rid of the dirt and debris.
