Ultraviolet light has been used in hospitals for years to kill pathogens like bacteria and viruses as part of the sterilization process. By using a similar technique, a UV light air purifier can help to keep the air in your home healthier, which is especially useful in humid areas like Southwest Florida. There are three different types of UV light air purifiers, but they all function in a similar fashion.

UV Light Air Purifier Types

The most common UV-based air purifiers are:

  • Air handler-mounted purifiers: One or more UV lights is mounted inside the air handler cabinet, illuminating the filter, the evaporator coil and the interior surface of the air handler.
  • Duct-mounted purifiers: A special system including UV lights is mounted in the duct system, typically on the return side.
  • Standalone systems: These are self-contained air purifiers that can be used in any room, up to the rated capacity of the system.

How They Work

The UV light inside the air purifier shines on any microorganisms located on nearby surfaces or in the air stream, within a certain distance from the UV source. Any viruses, bacteria or other microorganisms that are exposed to the light for more than about half a second will have their RNA or DNA degraded by the UV light, killing them.

Certain types of UV-based air purifiers work better than others, because they allow the microorganisms to be exposed to the UV light for a longer period. Generally, air handler-based systems or well-designed standalone systems produce better air quality than a duct-mounted system, which sometimes has air moving too quickly to treat effectively. A properly-designed system, however, can overcome this.

UV light can also break down odors and volatile organic compounds, leaving the air fresh. Moreover, it can reduce A/C maintenance by keeping the evaporator coil cleaner and preventing algae growth that clogs the condensate drain.

In some homes, issues with heating and cooling may make it difficult to use a standard furnace, heat pump, or air conditioner. If this is the case, a zoning system is often the best and most practical answer. Here is a brief introduction to how they work to keep your home comfortable.

zoning systemWhat Is a Zoning System?

Zone Systems concentrate heating or cooling in specific areas, or zones, of your home. Zones can be as small as a single room or as large as an entire floor of the structure.

They work in tandem with your existing HVAC system to ensure better and more precise control of comfort levels in the appropriate areas. They use a series of individual thermostats to control temperatures in the zones. Motorized dampers in the ductwork open or close in response to temperature needs, either increasing or decreasing the amount of heating and cooling reaching the zone. In this way, a zone system allows for precise temperature control within the one area without affecting temperatures in surrounding zones.

Why Use a Zoning System?

These systems are useful when you need better control over the heating and cooling in your home. For example, they help when:

  • It is difficult to provide consistent levels of heating or cooling throughout your home because of large floor plans.
  • Occupants need or want different levels of heating or cooling in their rooms. This allows individual temperature preferences to be met and eliminates conflicts.
  • Certain rooms or floors of your home need more heating or cooling than others.
  • Areas of your home need to have the amount of heating or cooling reduced because they aren’t being used.

A new HVAC system usually represents an investment of several hundred dollars or more. In most cases, new HVAC equipment will be covered by a manufacturer’s warranty that protects you against certain types of defects or problems. Warranties can be voided, however, if you don’t follow appropriate procedures. One of the most common ways of voiding an HVAC warranty occurs if you try to repair the system yourself. If your cooling system is still under warranty, it’s best to avoid DIY repairs and leave these matters to an HVAC professional.

voiding an HVAC warrantyMaintaining Valid Warranties

To ensure the warranty remains valid and that the manufacturer will honor the warranty, you must ensure that repairs and preventive maintenance are performed by HVAC professionals. It may be tempting to try to avoid a repair bill by trying to fix problems yourself, but unless you are a qualified HVAC expert, leave the repairs to the pros. In some cases, the HVAC pro you use may even need to be trained and certified by the company that made your HVAC equipment.

By relying on an HVAC professional, you can be sure that the work is performed properly, that the system will work correctly when the repairs are complete, and that the system will be safe to use. Manufacturers will be assured that proper procedures have been followed during the repair, that authorized parts have been installed, and that other problems haven’t been introduced into the system during the repair procedure.

Maintenance You Can Do

While significant HVAC repairs require the services of a licensed professional, there are some minor maintenance tasks you can perform that will leave your warranty intact. These include:

  • Changing air filters.
  • Cleaning the interior and exterior of the cabinet.
  • Clearing grass and other vegetation from outside of the unit.
