Ductless AC repair in Riverdale NJCarbon Monoxide

Protecting your family and home from lethal carbon monoxide poisoning is simple: Keep a Carbon Monoxide Detector on every floor of your home, at least four feet from the floor. KEIL ensures that your home is equipped properly with these life-saving detectors and offers installation and maintenance on a brand we recommend over all others:

The NSI 3000

  • Provides protection for all age groups and conditions, especially infants, children, the elderly, and highly sensitive or ill people. (Other detectors barely provide minimal protection for healthy adults.)
  • Lets you know there's a problem before reaching dangerous, even deadly CO levels, long before the other detectors even begin to work.
  • NSI's Model 3000 Monitors employ the same electrochemical sensor technology found in professional CO Analyzers that cost thousands of dollars. These monitors are calibrated using CO, not electronic guesswork.
  • Replaceable 9V battery ensures operation even when power is out. 3-year limited warranty
  • Continuous Scan™ mode lets you know monitor is checking for CO – 24/7

Condensate Management

Condensate Pump

Condensate Pump

Removes the nuisance of ugly hoses or pipes running across the floor.

Condensation or wastewater is a byproduct of high efficiency furnaces, air conditioning evaporator coils, and flow- through humidifiers. A condensate pump is used to transfer this wastewater to a proper drain.



This clear PVC condensate trap allows you to see when a drain line clog is building up to the point of backing up. A simple swoosh of the attached cleaning brush allows you to clean away any trapped buildup or slime that could otherwise block the drain line, causing water to back up and flood the area.

EZ-Trap is a cost effective and “EZ” way to insure your air conditioner does not back up and create a watery mess on your floor or ceiling!

Kool Kap

Keep Your Outdoor Air Conditioning Unit Clear of Debris!

Kool Kap

Protect your air conditioner year round with a Kool Kap. Day in and day out, your air conditioner’s condensing unit is subjected to the sun, rain, snow, ice, leaves, dirt, sticks and other debris. This debris collects in the bottom your condensing unit and traps water, snow and ice. All this trapped moisture causes your system to prematurely rust and corrode, damaging your system. By keeping your condensing unit clean, it will run at peak efficiency saving you money on your utility bills. Once a Kool Kap is installed, you never have to fuss with it. The Kool Kap remains on your condenser year round, so put it on, let it work and forget about it.

This revolutionary product works without chemicals, salt or plumbing to help reduce scale buildup and prevent scale formation.

The ClearWave-HD works on all types of pipe including copper, PVC, galvanized and stainless steel. If iron is present in your water supply, we recommend the use of an iron filter prior to the ClearWave-HD.

When to use the ClearWave-HD: For the use with commercial dishwashers, ice makers, coffee/tea makers and boilers. To reduce spotting and other hard water problems in car washes. Can be used with hot tubs and swimming pools. Industrial applications include poultry farms, breweries, distilleries, soft drink manufacturers, dairy farms, ice factories, paper and steel mills, Merchant Marine, and Navy.

The ClearWave™ is the most advanced hi-tech computerized anti-scale device available today. It operates by using a programmed ‘chip’ to constantly cycle through and induce over 200 different electro-magnetic low frequency wave pulses into the water. These wave pulses produce water with remarkable anti-scale properties, without adding salts or chemicals, at an operating cost for electricity of approximately $5.00 US per year.

How It Works

Pure water contains nothing but H20. But water, as it comes out of the ground, is rich in a multitude of minerals. Minerals such as calcium and magnesium are the main components of hard water, and the cause of scale formation and other problems.

There are three basic methods used to control the problem of hardness and specifically scale formation.

mineral build-up
Left: Water Heater    Right: Water Boiler

ION Exchange

One method is to remove the calcium and magnesium from the water through ion exchange (the traditional water softener). This method requires the use of a resin filled tank with a high concentration of salt ions. As the water flows through the resin tank the salt ions (typically sodium) are exchanged for the calcium or magnesium ions. This lowers the concentration of the minerals that cause scale and therefore inhibits scale formation.

Chemical Addition

A second method used to control hard water scale is the addition of chemicals (such as phosphates) to the water. These materials chemically alter the scaling characteristics of the calcium or magnesium, allowing the concentration of the minerals to stay the same while still reducing scale formation and its affects.

Both of the above methods require the use of consumable materials to change the makeup of the water. For these devices to function properly, the homeowner must continuously replenish the salts or chemicals as well as perform periodic maintenance on the equipment. In addition to these inconveniences, the chemicals and salts discharged into the effluent water present problems downstream to the municipal water treatment facility and the environment. Many U.S. cities have been enacting and/ or evaluating environmental legislation to limit or reduce the levels of chemicals or salts that result from these types of water treatment methods.

Electric Potential

A third method used to treat the hard water problems associated with scale utilizes changes in electrical potential in the water to produce the affects of chemical addition. The electric potential applied changes the scaling characteristics of the calcium or magnesium without the removal of these ions or the addition of chemicals.

Operation Timetable

Day 1: The ClearWave action immediately starts to loosen existing scale in both the hot and cold water systems. One should find soap lathers more easily.

Day 5 and onwards: Scale begins to break down and come off water heater elements (immersion heaters) and tanks. Most particles are microscopic and will flow through your water system, but some small particles may be seen in the water coming from the hot water tap.

Day 10 to 16: It should be noticeably easier to wipe clean ceramic, plastic, glass, and metal surfaces. By now the quantity of bath soap, dish soap, laundry detergent, and laundry softening agents can be reduced. Scale should have loosened on faucets, showerheads, and frequently used appliances that boil water (such as coffee makers).

Day 16 and onwards: Scale should continue to loosen from faucets, showerheads, and pipes. With the continuing breakdown and reduction of scale from the heating surfaces of water heaters, water should heat quicker using less energy to achieve the desired temperature.

After 1 to 2 months: Any scaly crust or stains in toilets or under faucets should be significantly reduced. No new stains or crust should form. Mold that attaches to scale will begin to disappear from shower curtains and, once cleaned, should not reappear. Depending on the water hardness in the area, the full effects can take up to 12 weeks, especially if the system has been heavily scaled up over many years
