R22: What Does This Mean For Your Old Air Conditioner?

Homeowners with older air conditioners may soon be facing a difficult choice: replace their cooling systems or continue to pursue increasingly costly and hard-to-find R22 refrigerant when their A/C unit needs a tune-up. Standards for types of refrigerants used in air conditioning system maintenance are changing, and this means that this most common and least expensive refrigerant will soon be phased out. When the phase-out is complete in 2020, R22 refrigerant will no longer be available.

R22 refrigerant, sometimes known as R22 Freon or HCFC-22 Freon, is an environmental danger because it contributes to the depletion of the ozone layer. The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. At this point, R22 will no longer be manufactured and cannot be used as a refrigerant in new air conditioning systems. R22 is being replaced by R-410A, a safer material which is the current, compliant standard refrigerant in air conditioning equipment.

The refrigerant change means several things for homeowners with older A/C units:

1. R22 refrigerant may still be used, but it will ONLY be available through after-market sales when it is recovered from old systems that have been salvaged.
2. Prices for R22 refrigerant have been rising and are expected to continue to rise. 
3. The availability of R22 will be limited because it cannot be purchased new. If you need a recharge of R22 in the future, there is no guarantee that it will be available.
4. A complete A/C system replacement may be the most cost-effective solution.

What Is R22 Dry Charging?

While R-22 was outlawed in 2010 for use in new units, some companies are taking advantage of the law by producing what’s known as ‘dry charge’ units. These are new units that don’t have the refrigerant installed at the factory. Instead, a technician is required to come out to your home and install the R-22 refrigerant. While this practice is technically legal, this isn’t the best option for the following reasons:

• There is a limited supply of R-22 and its price will increase as supplies diminish
• R-410A offers greater efficiency, saving you in energy costs, and is much better for the environment
• Dry charged units typically offer much shorter warranty periods

Help! My Refrigerant is Leaking!

Refrigerant leaks are a common cause of your A/C freezing up. Whenever you're leaking Freon or other coolant, it’s a decision point for homeowners. When you have a leak, it’s best to either get it fixed or invest in a new A/C, depending on the age of your current system.

Yes, you can top off your coolant and get your system up and running again. However, it’s a temporary fix — and there’s no telling how long it will last. It could go a couple of months or a couple of weeks or a couple of hours before your A/C is frozen again.

If you suspect a leak, contact Air Factory Heating & Cooling as soon as possible at (405) 243-1613. Let a licensed technician pinpoint and repair the A/C issue before it causes any other headaches.

R22 and R410A: What You Need To Know

One of the hottest discussions within the air conditioning and heating industry is the difference betweenR-22 and R-410A refrigerants. As a homeowner considering a purchase, it’s important that you understand the difference so you can make the best decision for your system. We’ve outlined below the main differences and why they matter.

R-22

• Often referred to by a brand name like Freon®
• As of 2010, R-22 was discontinued for use in new air conditioning systems
• R-22 is a hydro-chlorofluorocarbon (HCFC) which contributes to ozone depletion

R-410A

• Often referred to by a brand name like Puron®
• Has been approved for use in new residential air conditioners
• Is a hydro-fluorocarbon (HFC) which does not contribute to ozone depletion
• Will become the new standard for U.S. residential air conditioning systems in 2015

Performance Differences

Newer air conditioning models are designed to be used with R-410A for reliable and more efficient operation. Because R-410A can absorb and release more heat than R-22, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating.

R-410A also functions at a higher pressure than R-22, so new compressors are built to withstand greater stresses, reducing the chance for cracking. If you were to put R-410A refrigerant into a system designed for R-22, the pressure would be too much and the unit would break.

All air conditioners use an oil to keep the compressor lubricated during operation. R-22 air conditioners use mineral oil and R-410A systems use synthetic oil. The synthetic oil is generally more soluble with R-410A than mineral oil is with R-22. This means the R-410A system operates more efficiently reducing wear and tear on the compressor.

How To Pest Proof Your HVAC Components

Prevent pest infestations and the problems which go along with it by taking steps to make sure your HVAC system and its components are protected.

Seal Your Ducts

Gaps, cracks, and larger disconnections in the duct system create points of access for pests to enter your HVAC system as well as your home or building’s interiors. Insects, mice, and larger vermin may enter the duct system, depending on the size of air leaks.

Not only can pests in your ducts cause damage to the ductwork itself, it can cause serious indoor air quality issues. Excrement and dander left behind by the pests will spread into your interiors as conditioned air circulates through the duct system, posing a health hazard to occupants.

Treating with pest poison isn’t an ideal strategy for a duct infestation. Sure, it can kill the pest, but they’ll likely die within your duct system, creating a problem in and of itself. Decaying rodent carcasses within your ductwork can spread odors through the structure, and locating them for removal can be a challenge. Spraying pesticides into the ducts will cause the pesticides to recirculate back into your home or business.

Trapping is a better option when ductwork is infested; live traps can be set inside the ducts to trap larger pests such as mice and rats, so they can be removed, while glue traps can be used to catch insects. Ductwork should be professionally sealed and you may elect to treat the home or business with pesticide to prevent reinfestation. Duct cleaning can remove dead pests as well as the debris they’ve left behind to improve indoor air quality.

Install flue and vent covers

Your HVAC system utilizes flue pipes to expel byproducts of combustion from the furnace; these pipes must be in good working order to protect occupants from dangerous carbon monoxide poisoning. If critters, such as birds and chipmunks, enter the flue pipes and perish, their remains can block the flue, forcing combustion byproducts back into the home or building.

Your home or business may also have fresh air intakes and other exterior vents which are components of ventilation systems, such as whole-home ventilation or exhaust fans for kitchens and bathrooms. Pests can enter the building through exterior vents, and often find these areas to be an ideal location to build their nest.

Vent covers should be installed on all exterior flues, intakes, and exhaust vents. These covers will block pests’ point of entry, preventing them from travelling inside your home or business, and keeping your pipes clear of nests. These covers have additional benefits, such as keeping rain water out of your vents. Make sure vent covers are installed securely; small animals can be resourceful, and may find a way to pull off your covers if they are not on tightly.

Protect your air conditioning condenser

Rodents and other small animals can cause great damage to your exterior air conditioning condenser. They can damage components by chewing, scratching, urinating, and more – even their presence can harm the system, should you happen to turn the air conditioning system on when they are inside.

Your best line of defense in protecting your condenser is preventing rodents from coming near it to begin with. Keep the area surrounding your condenser clear by cleaning around it on a regular basis. Cut away vegetation and clean excrement, which can attract vermin to the area initially. Warm water and a mild soap can be used to scrub the exterior of the unit as well as the surrounding area.

Use a pet repellant to deter animals from coming to the area. Pet repellants contain scents which are unattractive to animals, so by spraying it on the condenser its surroundings, animals will not want to come nearby. Pet repellants are a safer alternative to chemical pest treatments as they are natural, so you won’t risk the negative side effects of pesticide exposure when working to prevent pest issues.

Why Are Air Filters In Your Home Important?

DID YOU KNOW? Regular filter changes cut 5% - 10% off your energy bill every month.

100% of the air in your home passes through a filter, typically twice every hour. Since clean, quality air filters keep the air in your home fresh, the people inside stay healthier. A quality filter captures the harmful bacteria typically found in sneezes, coughs, viruses and molds, as well as pollutants like dust and car fumes.

Clean filters also keep your HVAC system healthy—they enable it to run more efficiently, keep repair costs to a minimum, and reduce monthly energy bills. About half of your monthly energy bill is attributed to HVAC, and keeping clean air filters is the single most effective way to improve HVAC efficiency. Clogged filters make the HVAC work harder as it conditions your home, which raises your energy bill. (And if there are no filters, the coils will clog, which is even worse for your system.)

We recommend changing filters at least every 3 months, but every 1 to 2 months will usually serve you better (especially if you have a busy lifestyle, family with allergies, pets in the home, etc.).
