Airborne Contaminants and What to Do About Them

Tuesday, March 10th, 2015

As you sit here reading this, you are likely inhaling millions of microscopic particulates. Most of these are harmless, and those that can cause harm are often not in high enough concentrations to be a threat. Under certain conditions, however, these airborne contaminants can lower your quality of life. Let’s take a closer look at what these airborne contaminants are, what they can do to you, and how to get rid of them.

Airborne Contaminants

You’re probably already aware of a few of these contaminants, especially if you have allergies. Dust and pollen are quite common in homes, and cause allergy attacks in many people. Those aren’t the only lung irritants floating around, however. Dust mites, insect dander, pet dander, and mold spores are common as well. All of these can inflame sinuses, as well as cause sneezing and coughing fits. The other contaminants are, unfortunately, even worse.

Viruses and bacteria are present in many homes, as well. The common cold and flu viruses are both communicable through the air, and are the most common illnesses contracted this way. Oftentimes, the airborne germs in your home are too few to penetrate your body’s natural defenses. There are a few exceptions, however. If someone else in your home becomes sick with one of these, the number of viral or bacterial cells in the air will definitely rise. Low humidity in your home can also lower your body’s defenses by drying out the mucus membranes in your sinuses. This makes infection more likely. So, what can be done about these airborne contaminants?

Duct Sealing

The ducts in your home are often a haven for germs and other contaminants, due to their dark and out-of-the-way qualities. These contaminants tend to enter the ducts through leaks and other gaps, then build up in the ducts until a forced air system is turned on. At that point they are circulated throughout the house to infect people.

Duct sealing finds and closes any leaks in the ductwork, preventing contaminants from entering the ducts in large numbers. Duct sealing can also include the application of antiseptic to the inside of the ducts, to kill any harmful germs that may already be present.

If you haven’t had your ducts sealed in a while, call Johns Refrigeration. We provide duct sealing throughout the Scottsdale area.

3 Problems Caused by Leaky Refrigerant

Friday, August 22nd, 2014

One of the essential components that makes an air conditioner work is refrigerant, a chemical blend that courses through the cooling system and changes from gas to liquid and back again. As the refrigerant absorbs and releases heat, it moves heat from the inside of a home and deposits it outside. This is calledheat exchange, and it’s the secret to how electro-mechanical air conditioning works.

During heat exchange, the amount of refrigerant inside an AC doesn’t lower. As long as the system is working normally, the air conditioner will not lose of its charge of refrigerant. However, the charge can drop if leaks develop along the refrigerant lines or inside the compressor. Loss of refrigerant is a serious repair problem that will impair an AC and possibly cause it to break down permanently if not dealt with.

If you notice a loss of cooling from your AC or hear an unusual hissing noise coming from its cabinets, call Johns Refrigeration right away. Since 1970, we’ve handled air conditioning repair in Scottsdale, AZ that keeps customers coming back to us.

Here are the troubles you may encounter with your AC due to leaking refrigerant:

Loss of Cooling/Rise in Bills

With less refrigerant inside an air conditioner, the balance of heat exchange will weaken. The indoor evaporator coil will be able to absorb less heat, and the outdoor condenser coil will be able to exhaust less heat. The air conditioner as a whole will start to lose its cooling power, and consequently it will strain harder to reach its target temperature, leading to a spike in electrical bills.

Ice along the Evaporator Coil

One of the major warning signs of leaking refrigerant is ice and frost developing along the indoor coil. Although it might seem strange that losing refrigerant would cause ice to appear, the reason this happens is that the remaining refrigerant in the coil doesn’t warm up enough, and the cold along the coil will start to freeze the water vapor in the air. This creates a downward spiral, since ice will further prevent the coil from absorbing heat, leading to more ice. Eventually, a solid ice block will form over the coil and prevent any heat exchange from occurring.

A Burnt-Out Compressor

This is the most serious consequence of a loss of refrigerant: if the compressor burns out, usually the entire air conditioner will need replacement. The danger to the compressor is that a reduced level of refrigerant inside it will cause it to overheat, eventually melting its wiring and ruining it. For this reason, you cannot delay when you notice any sign of lowered refrigerant.

One way to avoid the troubles from refrigerant leaks is to enroll your AC in a maintenance program. During a yearly inspection, a technician will check the refrigerant level to make sure that it hasn’t lost charge. If there are leaks, the technicians will locate and seal them, and then recharge the refrigerant to its proper level.

When you need air conditioning repairs in Scottsdale, call up the experienced team at Johns Refrigeration. We will have your cooling restored in no time.

The ENERGY STAR Program and What It Means for Your AC

Monday, June 16th, 2014

You are probably familiar with the ENERGY STAR logo: a white star on a blue background next to the cursive word “energy.” You see it on many types of appliances, from computer monitors to refrigerators… and also on air conditioners. With this label appearing on so many different devices, you may wonder what it has to tell you about your air conditioner. We’ll explain.

For all your concerns and questions regarding air conditioning in Scottsdale, you have a reliable source: Johns Refrigeration. Since 1970 we have served the Valley of the Sun with quality air conditioning and heating services. Trust to our knowledge to keep your AC running year after year.

The U.S. ENERGY STAR Program

The ENERGY STAR label (always written in all-caps) indicates that an appliance meets the requirements of the ENERGY STAR program. The U.S. Environmental Protection Agency initiated this program in the 1990s as a way to help consumers and businesses save money through energy conservation and to help protect the environment.

The ENERGY STAR program sets out requirements for appliances that will make them more energy-efficient and lower their polluting abilities. The program is voluntary: any company can decide if they want to submit their products to the program for qualification.

Each type of appliance has a different set of requirements to meet in order to receive the ENERGY STAR certification. In the case of an air conditioner, a system must have at least 14.5 SEER (seasonal energy efficiency rating) and 12 EER (energy efficiency rating) and contain specific features that consumers demand. The technology used to achieve the high efficiency ratings must not be proprietary: energy-saving performance of this type must be available to all companies.

Do you have an air conditioner with the ENERGY STAR label of approval on it? If you don’t know, check on it right now. For an older air conditioner, it’s possible that it doesn’t meet the program requirements. If your AC isn’t ENERGY STAR approved, you should consider installing a replacement unit that is. Even an older ENERGY STAR-approved air conditioner might not have the efficiency of newer systems (the program’s requirements have changed of the years).

If you want new installation of an ENERGY STAR air conditioning unit in Scottsdale, AZ, contact the experienced team at Johns Refrigeration. We can help you find the ideal energy-saving AC to cool down your home and save you money.
