Is your air conditioner struggling to cool your home? According to Energy Star – a U.S Environmental Protection Agency voluntary program, most modern HVAC systems or air conditioners are built to last an average of 15 years, completely dependent on make & model, as well as your climate, how often you run the system, and how often your air conditioner is maintained.

Your air conditioner is something most of us take for granted, and never really give any consideration to until it breaks down & leaves us vulnerable to the elements. When this happens, you’ll rush to find an HVAC company to come to your home, and hope they provide a quick & easy fix. However, sometimes these “quick & easy fixes” can’t actually be completed easily, quickly, or even cheaply.

When this happens, you have a pretty big decision to make: repair or replace your existing air conditioner system? How can you know what the best decision is for you, your home, & your wallet?

When Cold And Flu Season Rolls Around, UV Lights Ramp Up Your Protection

uv lights northwest arkansasUV lights help keep your family healthy and well during cold and flu season. They significantly decrease the amount of mold, bacteria, allergens, and viruses in your air, as long as the lights are installed correctly.

UV lights play an important role, especially in the winter:

  • Interior air becomes polluted without proper ventilation. In the winter, most homeowners don’t open the windows as often, and as a result, pollutants accumulate inside. This raises the risk of wintertime ailments such as colds and flu.
  • Stop organisms from reproducing. UV lights are installed inside your ducts so that micro-organisms in your air have to pass through the lights before the air circulates in your living spaces. When the UV rays shine on mold, mildew, bacteria and viruses, their DNA is altered to the point that they can no longer reproduce. This effectively eliminates them.
  • Lessen the demand on your HVAC system. When fewer pollutants are in your air, air filters stay cleaner and last longer. Keeping your filter in good condition is vital because dirty filters block airflow, which puts strain on the blower motor and other components, and robs your system of efficiency. Clean filters also do a better job of trapping particles so they cannot settle inside your system, which eventually can cause damage.
  • Easily maintain high air quality. The bulbs for your UV lights only need to be changed about once a year. They are typically installed in your ducts close to a vent, or at the coil of your heat pump, so you can easily look in and see when the bulb is out. When it is, just unscrew the vent and change the bulb just like you would any light bulb.
  • Use other filtration as well. UV lights don’t do anything to scrub non-organic particles from your indoor air. This is why a comprehensive indoor air quality strategy also requires effective air filtration as part of your HVAC system.
