Want To Install An HVAC UV Light? Allow Us To ‘Illuminate’ The Details

If you’re looking at ways to improve the air quality in your home, you may have seen some information about HVAC UV light systems. As we’ve mentioned in previous posts, these UV lights for your AC system or air handler can go a long way towards improving indoor air quality, reducing odors in your home, and improving the efficiency and longevity of your system, generally making your home more comfortable.

But how do they work? What makes these lights so effective at combating airborne allergens, mold and other nasties? We’d like to “illuminate” the UV light topic for you.

How An HVAC UV Light Works

The lamp is installed in your central air system, either right above or right below the evaporator coils. The ultraviolet light generated by the bulb (UV-C) penetrates the cell walls of mold and other microbes and scrambles their DNA. Think of these germicidal lamps as “death-rays” for mold and bacteria. UV-B light is normally filtered out by our atmosphere, so microorganisms have no defense against it.  Any surface that the light shines directly on is fully sterilized within 24 hours of turning the germicidal lamp on, and any airborne microbes are killed as the air circulates through the system and passes by the lamp.

Mold thrives in the interior of your air handling system, since dark moist areas are mold’s best friend. By installing the UV lamp near the evaporator coil, the germicidal properties of the UV-C light prevent mold from growing on the coils, which helps improve the efficiency and longevity of your system.

Airborne biological contaminants are killed as the air circulates through the system. The EPA states that indoor air pollutants are often more harmful than outdoor pollutants. The UV light system kills mold, bacteria, viruses and other allergens. This greatly improves the quality of the air inside your home, and helps reduce odors.


An HVAC UV Light Is An Investment In Home Comfort

When you compare it to the benefits that an HVAC UV light system provides, the value in your investment is astronomical. The initial installation costs less than $500. A replacement bulb (installed) costs about $160. When you break that down over the life of the bulb, you’re looking at a monthly investment of less than five dollars to greatly improve the level of comfort and health of your home.

Fall Allergies – Steps To Enjoy Your Autumn

As the leaves begin to fall and the pumpkin harvest begins, allergy sufferers face a whole new and different set of challenges. Fall allergies have different causes and different situations that can be easily dealt with, just in a slightly different manner than spring allergies.

Fall Allergies and Hay Fever – Not Just for Horses Anymore

“Hay Fever” is a term from years past that was used to describe the general symptoms of late summer and fall allergies. While it has nothing to do with hay specifically, these allergies often coincided with the beginning of the harvest and hay-making season. The actual condition is referred to by the medical community as “allergic rhinitis”, and includes symptoms such as a stuffy or runny nose, itchy eyes or mouth, sneezing, congestion and fatigue.

The causes of allergic rhinitis basically fall into three major categories: outdoor allergens, indoor allergens, and irritants. Outdoor allergens include things like tree and plant pollen. In our area, Ragweed is a notorious hay fever trigger, as it begins to pollenate in August and can continue to do so until the first frost of the season.

Indoor allergens encompass things like pet hair and dander, dust mites, and mold spores. Lingering warm weather in the fall can cause the symptoms of fall allergies to last longer. Mold spores can be released when the humidity is high, OR when the air is dry and windy.

Irritants, such as cigarette smoke, perfume, or diesel exhaust aren’t really a seasonal thing, but also contribute to the pesky symptoms of hay fever.

Outdoor Allergens

There’s not much you can do to effect the level of allergens and pollutants outside, but there are steps you can take to reduce your exposure to these irritants. Staying indoors when pollen counts are at their peak is always a good idea for allergy sufferers. Wearing sunglasses or glasses when you’re outside can help keep pollen out of your eyes. Avoid hanging clothing or linens on an outside laundry line, as pollen can cling to the fabric as it dries.

The American College of Allergy, Asthma and Immunology recommends that allergy sufferers use a NIOSH rated N95 mask when raking leaves or doing yardwork in the fall months. Using your air conditioning when in the car can help filter the air and reduce the level of airborne contaminants.

Indoor Air Quality

There are a lot more steps you can take to improve the air quality inside your home, and reduce the contaminants that contribute to fall allergy symptoms. Just like in the car, running your air conditioning can reduce the amount of airborne contaminants. Simple steps like installing a UV light in your air handling system can reduce these contaminants even further. These UV lights, combined with keeping the humidity low, also help to limit mold growth. Remember to replace the air filters in your duct work every three months to help improve indoor air quality.

Washing your bedding frequently with very hot water will help control dust mites. Using a “mite proof” bedding cover can also help reduce these pesky critters.

If you have pets AND allergies, make sure you wash your hands after petting your animal. It’s also best to let a non-allergic family member handle your pets grooming, preferably in a well ventilated area. Using a damp mop to clean floors and replacing carpeting with hardwood, tile or linoleum will also help with pet dander build up.

Heater Maintenance Made Easy – The 7 Oil ‘Clean & Tune’

Whether you’re using oil or natural gas to heat your home, there are certain heater maintenance items that should be taken care of on an annual basis. They differ slightly based on the type of equipment you have, and our technicians can help you no matter what fuel source your home uses.

We have a comprehensive yet economical service package to make it easy to maintain your heating system. We like to call it the “Clean & Tune”.

Heater Maintenance Benefits

First, we’d like to let you know why heater maintenance is important. Whether it’s gas or oil fired, your furnace accrues normal wear and tear, like any machine. Yearly maintenance helps mitigate this wear and tear and extend the life span of your equipment. For example, under normal working conditions, oil fired furnaces will acquire some soot build up in the smoke pipe, chimney base, and in the heater itself. Removing this build up once a year helps your heater last longer and run more efficiently.

When Is The Best Time and How Often Should Heater Maintenance Be Performed?

The timing of your heater maintenance is really a matter of personal preference, but many homeowners choose to have this maintenance done in late summer or early fall. That way, you have peace of mind for the oncoming cold season that your heating system is working properly and at peak efficiency.

Under normal usage conditions, we recommend that maintenance and cleaning be performed annually. Regular cleaning and maintenance once a year will help eliminate costly repairs at other times of the year.

Oil Heater Maintenance

As mentioned above, the maintenance item required by oil fired and gas fired furnaces differ slightly. With an oil fired furnace or boiler, the technician will first clean the heater, the smoke pipe, and the chimney base. He then changes the nozzle and the oil filter, and pump strainer. He will inspect, clean and adjust the ignition electrodes.  If your oil furnace is a forced air system, our technician will also change the air filter.

Next, he’ll inspect the combustion chamber, blast tube, and end cone. He will inspect all the circuit boards and electronic components for proper functionality. Once the unit is reassembled, he will run it to ensure everything is working properly.

Gas Furnace Maintenance

Natural gas fired furnaces require slightly different maintenance. Our technician will first clean and inspect the ignition system, whether it’s a hot surface igniter, pilot light, or electrode. He changes the air filters, and then inspects all circuit boards and other components, paying particular attention to safety limits. He will electronically check the heat exchanger for signs of carbon monoxide leakage. Lastly, he will reassemble the unit and run it, checking it for proper functionality.

We’d be happy to schedule a Clean & Tune on a day that’s convenient for you! Simply give us a call at 856-786-0707 and one of our customer service representatives will be glad to assist you.
