This Happens More Often Than I would Like...

We received a call to replace A/C unit.  I met with the customer, an older lady and her husband.  They said the system had frozen up inside the furnace, and was dripping along the refrigeration lines. 

I asked them if we could turn it on.  They were convinced that it needed replacement as the previous Contractor had told them so. I finally convinced them to turn it on.  The A/C unit started, and started producing cold air.  I checked the unit outside and the system seemed normal but needed proper cleaning of condenser.  I had noticed a very dirty filter beside the furnace, and they said they had just changed it.  I determined that the dirty filter was the cause of the unit freezing up, due to poor air flow. I told them I would send out a crew to clean the unit and recheck operation.  Our crew reported that the system was working perfect after it had been cleaned.

We had later followed up with our customer. 

She had said that she “was very happy that she had called for a second opinion” and that she “had finally found an honest contractor.”  

I asked her to place a review on Homestars.

Good morning all.

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.
