2 Key Factors that Affect HVAC Efficiency & Be Sure Maintenance Includes Them

Published on: August 16, 2012

When it comes to saving money on your HVAC system, you do not want to be caught behind the eight ball on expensive air conditioning repair or maintenance calls. With the weather in many parts of the world becoming more volatile and unpredictable, keeping up with routine maintenance checks on your HVAC system has become more important than ever.

 

Avoiding air conditioning repair or maintenance calls is one of the ways to bring down the budget of a household without any decrease in the quality of life. It is also a very useful discipline for small and midsize businesses who must make sure that their funds are relocated to visibility and customer conversion marketing efforts.

 

The efficiency of an HVAC system is what drives its need for air conditioning repair or maintenance. The less that an air-conditioning system has to work to achieve the climate effects that you want for your space, the less that you will have to deal with air conditioning repair or maintenance calls that can quickly drain your wallet.

There are two factors that affect the efficiency of your HVAC system more than any other. Below we will describe those two factors and explain exactly why your HVAC system repair person should check on them every time a routine maintenance call is in order.

 

The First Factor

The first and most important factor that you must regulate in order to maximize the efficiency of your air conditioner is your airflow. Airflow is the ease with which air can be received into the air-conditioning unit and travel with it.

The first thing that must be done is to keep a clear path between your air-conditioning unit and the outside air. If you have an outside power or compressor unit, be sure to keep at least 2 feet of distance between it and any shrubbery or other structures that may obstruct the outside air flow.

This means that if there are branches hanging over the outside unit, they must be cut down. Bushes and shrubbery that are within this radius must be pulled up. Although man-made structures may not be as easily removed, you still want to do what you can to increase the radius between any tall man-made structure that may be blocking the airflow to your outside unit.

This will also decrease the amount of work that your compressor and filters have to do. Shrubbery and other wildlife in the direct airflow of your air conditioner bring a plethora of contaminants that would not otherwise be there if the radius was clear.

In order to make sure that the airflow inside of your air-conditioning unit is at maximum capacity, you must keep your filters as clear as possible. This is much easier with the newer types of HVAC systems on the market today, but even if you have an older version, this discipline cannot be overlooked.

If your filters work too hard, then you decrease the efficiency of the entire unit. You will have to use more energy to get the same kind of climate control in your living space. This will naturally increase your heating and cooling bill at the end of the month as well as break down your air-conditioning unit more quickly. No one needs to spend even more money on air conditioning repair or maintenance than is absolutely necessary, and clean filters can ensure that you do not.

Although many newer air conditioning systems are ductless, if you still have an air-conditioning system with ducts, you should check the industry standards to make sure that your ducts are the appropriate size for your living space. If they are too small, this has the same effect of blocking the airflow within your air-conditioning unit and decreasing the overall efficiency.

 

The Second Factor

The refrigerant that is inside of your air conditioning unit directly affects the overall efficiency of that unit. Either too much or too little refrigerant will stop the flow of materials through your air conditioning unit and decreased efficiency.

If you have too little refrigerant in your air conditioner, odds are that you have a refrigerant leak somewhere. This is something that should only be handled by a licensed professional, because most refrigerants contain chemicals that are highly toxic to the human body.

You can determine the amount of refrigerant that your air conditioning unit needs by consulting a licensed professional or the industry manuals that are readily available on federal government websites.

One of the main things to realize when you are checking for HVAC efficiency is that neither of these factors are necessarily included in a routine check up; you must ask for them to be checked in order for the technician to take a good look at them. Make sure that you always ask for your airflow and your refrigerant levels to be checked and you will increase the efficiency of your air conditioning unit substantially.
