Your first step in every Zero-Energy Building Program


There has been very little innovation and progress made towards increasing the actual energy cost savings of HVAC and Refrigeration systems in the previous decades. Besides better insulating materials, most of the manufacturers of cooling equipment have used their resources to create a conversation about energy efficiency rather than energy savings. Energy Efficiency is a relative measure of what was and what might be, while Energy Savings is an absolute, recurring, and measurable number.

Cooling equipment manufactures profit off of selling their customers as much equipment as possible, and coupling them with expensive maintenance packages. These two revenue streams are both self-serving and self-preserving. And accordingly, they are very protective of any innovation or technology that will affect their bottom line. As a result, these manufacturers profit from the increasing inefficiencies and the refrigerant buildup called “oil fouling” that both reduces efficiencies, causes premature replacement and increased energy costs. 

That just doesn't seem right!

Cold-Plus is the solution to your oil-fouling problem

What does a residential HVAC company owner in Port Saint Lucie, FL say:

What do you think of Cold-Plus?


"...bottom line- Cold-Plus works! And because it works... it’s the right thing for the customer to do. But it works only in equipment that is in fair-good condition, its not going to “repair” equipment that is worn-out and needs to be replaced."

"...we have seen a drop in coil temperatures, better humidity result and lower operating temperatures... It has extended the life of the equipment and increases its reliability...but we do not have to sell on energy savings alone....its just a plus to the above."

What has Cold-Plus done for your customers?

 "....cleans out wax, oil build up, lubricates compressor, teflon lines tubes, cleans up the system...we use it in 2-stage and multi-stage compressors. .. Cold-Plus has worked well in Lennox, Trans, Rudd, Carrier and other units... no problems ever over the last 8 years and more than 3,500 customers."

How often do you install Cold-Plus?

 "...we put C+ in every new AC unit that we install...and do not price it separately, but put it in the price of the new unit installation.....because it’s the right thing to do for the customer...their unit will last longer and work better...and it gives our  customers a reason to do business with us...we take care of them!"

What does the president of Bob Stith Heating, Cooling & Plumbing say about COLD-PLUS?

Where have you used Cold-Plus successfully?

"...for over a year now we have tested and installed Cold-Plus in residential systems, commercial systems and geothermal units in schools, universities, restaurants and industrial manufacturing buildings without one issue."

How's has it worked for you?

"...this product has proven to me that it extends the life of all of the AC and Heat Pump Systems that we have put it has reduced my customer's energy bills as promised....I wouldn't use it if it didn't".

"...I can tell you from personal experience that it works! It is not toxic and is safe for any system using refrigerant and the results are documentable"

Residential Use


How long does an application of Cold-Plus treatment last?

We do not actually know. This is because we have been using this in equipment for over 15 years without a failure or reduction in energy savings. Cold Plus is effective for the “system life”. We mean it when we say it is a one time treatment.

Will use of Cold-Plus have a negative effect on my HVAC equipment?

Absolutely not. Cold plus might be the most laboratory and field tested refrigerant product in the market. Cold-Plus is a chemically inert surfactant. Which means it does not react with other chemicals, heat or cold. It contains PTFE and uses a synthetic oil as a carrier. This combination allows your compressor to operate with reduced friction and the disastrous disturbance of oil-fouling. 

Cold-Plus is inert. It is mixed with the same synthetic oil that is already in your system. The proprietary ingredient has been circulating in millions of human bodies without any ill effect since the 1960s. It contains NO WAXES, or any other chemically clogging materials. The idea that this will harm your equipment is unfounded and scientifically proven to be false. We have over 14,000 actively operating  pieces of equipment to prove it.

If your HVAC consultant suggests that Cold-Plus doesn't do what it claims and can harm your equipment, they are not operating in YOUR best interest. And it might be time for you to find a new consultant that reads current literature and understands how compressors actually work. Also ask them to find you another more cost effective way to save on energy costs and prolong the life of your equipment. We will wager that they will suggest that you buy some new equipment from them.

It is an illegal business practice to threaten to void a warranty (Magnuson-Moss Act of 1975) on your cooling equipment by either an installer, distributor or manufacturer for using Cold-Plus.

So we make it a completely hassle free experience to you by offering a 14 year 100% satisfaction warranty on the compressor including all parts, labor and shipping costs.

What is the cost of Cold-Plus installation?

We guarantee a one-year payback or will refund the cost of the product.

The cost of Cold-Plus installation is the same as if you were going to refill your refrigerant. No special tools, techniques,certifications or procedures. 

Our retail cost is about $40 per ounce, making a home unit (under 5-ton) about $400.00 including the $150.00 professional installation and warranty. 

We are proud to boast that Cold-Plus is as cost effective to use as it is easy to install.

What are the primary benefits of Cold-Plus?

Cold-Plus offers energy savings for all refrigeration and cooling equipment, except ammonia based technologies.

You can expect to:

• Extend the life of your equipment so you don't have to buy a new system.
• Eliminate the effects of oil-fouling which leads to higher monthly energy bills.
• Protect your seals and bearings from the harsh chemicals in refrigerants.
• Quicker cycles and less of them means you get cooler...faster.
• Eliminate compressor service calls.
• Feel good about reducing your carbon footprint and doing your part to save the planet.

What makes Cold-Plus treatment different from other Synthetic Refrigerant Additives?


Cold-Plus™ is a proprietary inert nanoparticle-lubricant for use in the compressors in all HVAC and refrigeration systems. This PTFE nanotechnology was originally developed by DuPont to increase laminar flow and reduce blood clotting in veins and arteries during invasive surgical procedures. Due to the similarities between a biological heart and a mechanical compressor, the proprietary component, PTFE (Polytetrafluoroethylene) , was then added to an industrial lubricant so that it could create similar results in mechanical systems. 

The resulting compound is Cold-Plus™, which has been proven to reduce the energy consumption of HVAC/refrigeration systems and extend the lifespan of the unit. Cold-Plus™ is the only SRA (Synthetic Refrigerant Additive) with PTFE and is chemically inert and meets OSHA standards for handling safety. Its effect on increasing laminar flow, has been successfully tested at the National Renewable Energy Laboratory (NREL) in Golden Colorado, where it was verified that a 14% increase in laminar flow was achieved when using Cold-Plus™. These tests were conducted using a 20-ton Carrier cooling unit from Walmart. 

The effectiveness of Cold-Plus™ in increasing HVAC performance and increasing the system’s lifespan have also been statistically verified by Dr. Elizabeth Clarkson, the Chief Statistician and Senior Research Engineer of the National Center for Advanced Materials Performance (NCAMP) in Wichita, Kansas. Cold-Plus™ has been proven to reduce the electrical consumption of compressors by up to 30% in some older units. 

Cold-Plus™ has also been successfully implemented and proven in over 14,000 homes, businesses, automobiles, industrial construction equipment, and the professional racing industry over the last 10 years.
