Most homeowners are familiar with the air filter in their central air systems. It traps contaminants in order to stop them from circulating around the air in your home. However, your air conditioning system has another type of filter, too—the filter-drier.
The filter-drier is located in the refrigerant line, and its purpose is to trap contaminants in the air conditioner's refrigerant before they have a chance to harm the system. The filter-drier contains a desiccant that absorbs any water in the refrigerant, and it has a mesh screen that catches other contaminants such as dust, metal, and oil.
One of the many jobs that homeowners have in trying to keep their house running in top shape is maintaining their home's HVAC system. But whether it's calling for major repairs or just handling maintenance tasks, many people are confused as to how often they should be calling their local HVAC company to perform routine residential air conditioning services. Since every home is unique, there is no hard and fast rule as to the frequency of air conditioning service calls, but most agree that the more often your unit is serviced, the better it will run.
Older furnaces require more maintenance and attention than newer heating systems, which can mean adding steps to your usual upkeep. Thorough inspection of components, early repairs, and testing your circuits and electrical parts can help keep your old furnace in great shape.
Part Cleaning and Maintenance
As a furnace gets older, certain vital parts will start to fail or require maintenance to keep them working well. One example is the bearings on your furnace's blower motor wheel, which requires lubrication to keep them running smoothly.
You probably know the refrigerant in your air conditioner is what cools your house. When something goes wrong with the refrigerant lines, your AC can't cool as well and it may stop working. Here's a look at three refrigerant problems and what an HVAC repair technician might need to do to get your home cool again.

The refrigerant in your air conditioner is supposed to be at a steady pressure all the time.
As the summer weather begins to cool down a little, your AC is going to require some maintenance. You want to make sure to take care of things like cleaning the unit, changing filters, and minor repairs before turning it off.
