What is a UV light system and will it benefit my family to have one installed?

If you or a family member have allergies then an ultraviolet light in your ventilation system would benefit the health of your family. The benefit is that the UV light will effectively kill and prevent the growth of dangerous mold. Mold can be hazardous to the health of you or your family. Mold thrives in the dark, damp areas of your air conditioning and once established can be very expensive to eradicate. Also, in addition to killing the mold, the UV light will also do away with bacteria, viruses and allergens as they pass through your air conditioner. If you or any of your family members suffer from allergies such as those caused by pet dander or pollen, you will notice a marked difference in the quality of the air circulating throughout your home. The bulb needs to be replaced every one or two years. If you take advantage of a Service Plan with Wright Mechanical Services checking the bulb will be part of your yearly check up of your HVAC system.

Which UV system should I install in my ventilation?

A consultation with a HVAC professional can help you decide if a UV light in your duct work is beneficial for your home. You should not invest in such a system unless you also have a service plan. The bulb needs to be checked once a year and there are safety concerns. There are circumstances when the cost of installing and the maintenance of such a system outweigh the benefits.

How often should I have my ductwork cleaned?


Ventilation duct work

It is generally accepted that a homeowner should clean their ducts every three to five years. There are a few instances when it is strongly recommended. If you suspect that you have mold in your home it is a good idea to have the ductwork cleaned. Also, if you know that there are rodents or other vermin nesting in the air ducts. It is a time to have them cleaned if you have finished a major remodeling project to get the sawdust or drywall dust cleared out.

How do I check if my ducts are leaking?

Leaking air ducts will lead to a significant rise in your utility bill. They are easy to fix once the leaks have been identified. The first thing you want to do is turn your HVAC system on so that is blowing air. Once that is done you want to take and run your hand around the duct joints and places where ducts connect and feel for air blowing . Mark these areas with a grease pencil or sharpie. Next, you will want to look for smaller leaks. You will need a smoke pencil or a piece of incense to hold near the duct joints or fittings. If the smoke wavers erratically then mark those areas. Once you have found the leaks in your ventilation system, seal them by wrapping them in foil-faced tape or applying mastic with your hands or a paintbrush. Do NOT use duct tape. The glue will heat up and shrink the tape and it will leak again. For extra savings you can wrap your duct work in foil-backed fiberglass insulation. If you are serious about finding any other leaks after taking these steps then you can acquire a theatrical fog machine. Close all the vents and blow the fog into the blower and watch for any leaks you may have missed. If you have any questions or you are not sure if you can safely take these steps then you should contact a HVAC specialist.
