Guarding Against Covid

Many National Refrigeration customers have asked us what is the best way to safeguard their homes against bacteria and viruses such as Coronavirus. The solution we recommend is Phenomenal Aire’s Cold Plasma Generator. Installed in the ductwork of your home, this device “scrubs” the inside air to reduce floating particles — especially viruses.

Air Cleaners.

Upgrading an air cleaner, also called an air filter or purifier, is the quickest and most inexpensive way to improve the air quality in your home. There are affordable air filters to clear the indoor air of bacteria, viruses, pollen, animal dander, and other pollutants.


Good ventilation is more than air circulation. Effective home ventilation controls mold, dampness, exposure to hazardous fumes, and other risks to your family’s health and home. We create the environment where your family can breathe the fresh air they deserve.


Does your skin dry out in winter? Does your home come alive with static electricity? Many energy-efficient humidifier options are available to add the right amount of moisture to your existing heating system for a cozier living space during the winter.

UV Lamps.

Between regular HVAC maintenance appointments, mold, bacteria, germs, and odors can fester and grow in moist places inside your air handler and indoor coil (also called the evaporator coil). Our UV lights — installed right in the air’s path as it circulates — eliminate unhealthy pollutants before they get into the indoor air.


Humidity in the summer and dampness in the winter are inevitable, but you don’t have to live with it. A heating and cooling system alone can’t control humidity and dampness. A properly sized, energy-efficient dehumidifier can keep your air crisp and comfortable.

Fan Coil Units.

Many homeowners are surprised by how much their heating and cooling system improves with the right fan coil unit. Immediate benefits include cleaner indoor air and improved heating and cooling efficiency. Best of all, long-term savings show up every month in reduced utility bills.
