The dry, dusty Arizona climate makes it especially important to change the air conditioner filters in your home. Indoor air filtration is your first line of defense in achieving good health but is often overlooked. You’ve seen the air filter commercials on television; what the manufacturers don’t tell you is how restrictive some of these filters can be. Restricting air flow makes the system work harder which in turn increases your electric bill.
Resistance and Efficiency: Select a filter that is low resistance and high efficiency. If the filter you use is “sucked” into the space, you are using a filter that has too high a resistance. You’re actually making the system work harder; it’s like it is breathing through a small tube or having an asthma attack – the system has to work hard to cool your home. Less resistance is like breathing without asthma – it is smooth and efficient.
What size do you need? Not all homes or HVAC systems are the same. The proper size filter will help reduce the dust, dirt and other allergens that enter your home through the system. The technicians at John’s Refrigeration can verify whether your current filter is the proper size for the current system and filter selection.
Has your system been serviced recently? At John’s Refrigeration we offer preventative maintenancepackages to help keep your system running efficiently even through the heat of the Arizona summer. We check the HVAC system of your home or business annually making recommendations as we walk through our complete assessment. Regular maintenance means catching issues before they become major repairs.
What is a MERV Rating for an air filter? MERV Ratings measure the ability of an air conditioning filter to remove dust from the air as it passes through the filter. The higher the rating the more particles removed before they reach the air in your home. Ratings range from 1-16. The most common particles are pet dander, dust, smog, viruses, smoke, spores, pollen, bacteria and environmental contaminants such as pesticides. A rating of 5-8 is good for a residence; a rating of 9-12 is better for a residence. Our technicians can verify whether the current filter is the proper size for the current system and filter selection.
Changing the filter: Whichever air filter you choose for your home, it is important to change them regularly, perhaps once a month especially during the high-use, dry, dusty summer. Not cleaning or replacing the air filters causes the system to work harder. The results can be higher utility bills and repair costs.
At John’s Refrigeration, we want you to feel comfortable breathing clean air in your home or business. We recommend the Air Care electrostatic filters Silver Series which are low resistance and 84% efficient.
