Good morning all. 

This is Jack from Active Air Inc . Welcome to my blog

The cooling season is almost here and with the first hot day comes a rush of service calls.

Many of these calls are very simple to solve by changing the furnace filter. 

I recommend a pleated merv 8 filter for most applications. 

When I speak to customers they usually question what that means.

A pleated filter is not flat but in fact has many pleats to increase the surface area which allows the filter to hold more dust. 

The merv rating is a number given to indicate the efficiency of the filter. The higher the number, the higher it's efficiency. A merv 8 is a medium efficiency. 

The more efficient the filter, the smaller the dust particles it will trap . 

More on filters later but please remember to change it now.  

It may save you a service call and will increase your A/C's efficiency.
