With recent studies showing that the US spends more on air conditioning costs than the rest of the world combined, industry manufacturers have advised up to 19% of annual running costs are wasted due to poor maintenance.
Knowing this, when we recently moved into our new home and I discovered that the old Honeywell furnace uses a filter with unusual dimensions. As we moved to a smaller town, I thought that I would have to spend endless hours searching for the correct size filter. My friendly new neighbour told me to look for AirFilterBuy and find Honeywell replacement filters on the site. What a relief! I found exactly what I needed and within no time my filter was delivered with no fuss.
Indoors air and allergies
As our kids have some allergy problems, I made myself a list of signs to look out for to help me to see when to replace my filter. If you have allergies you should consider using electrostatic filters, they may be more expensive, but they tend to be very effective.
Did you know that the United States Environment Protection Agency recons that people “…with environmentally associated symptoms is apt to have been exposed to airborne substances originating not outdoors, but indoors”. They add that studies from Europe and the USA found that people spend more than 90% of their time indoors; home, school and your place of work. A clogged air filter could worsen the quality of indoor air; it also makes the furnace run harder than necessary, increasing your heating bills.
An interesting and sad fact is that candles; especially the heavily scented candles contribute to indoor pollution. Some may even still have a leaded wick! Look for candles that have wicks that are coated with beeswax or soy, which will reduce the harmful pollution caused by romantic candles lit dinners.
Signs to look for to replace your filter
First of all you have to know where the filter is located, not all furnaces have them in the same place. Many models have it close to the blower or the air handler; older models may have it inside a panel.
It is recommended by many manufacturers that filters need to be changed every ninety days or so (some even say monthly). If you have pets, or live with a smoker, you may consider replacing them more often. Another sign is when you hear your heating system starting up more than normal, especially if it is accompanied by a dusty smell. If your normally immaculate home seems to be dustier, or you actually see dust around the air vents, check the filter of your furnace. Sometimes if your nasal passages feel clogged, the filter could be the cause.
Furnace maintenance tips
It is obviously best to have your furnace checked and certified by a technician, try and fit it in before winter arrives. This will allow you to budget for any repairs or replacement parts that are required before you need your house warm.
Replacing your furnace filters regularly also ensures that you do not overtax your unit, and helps to keep your blower motor in good working order for longer.
Make sure that the supply registers and return airs vents are clear and unblocked. Ensure that they are not obstructed by clothes or furniture for instance.
Regularly check the blower assembly; make sure that the belt is not damaged or loose.
The price and efficiency of filters range from the expensive electrostatic furnace filters that capture smaller particles. Electrostatic filters tend to last longer between replacements. Then you find the better priced, pleated filters and finally the cheapest woven fiberglass filters.
