Nice Weather Today

Have you checked your filter today? How about you HVAC registers?? See any dirt, cobwebs, little dead critters around the air diffusers? Time to clean around them with a vacuum cleaner and make sure no more reappear.

Pleated Filters

There is quite an array of pleated filters on the market right now. Most HVAC contractors will provide a good cost effective choice with their maintenance agreements. A 1" pleated filter with spun media is what one would see most of the time for residential use. The pleated design allows more surface area for particles to be trapped on and allows for a tighter weave of material. These filters are said to allow for 90 days between changing--however if there is massive amounts of large particles the filters will clog and diminish air flow quite rapidly. Make sure you check the filter if there is any construction, roadwork, or extreme dust conditions around the house.
Next time: washable filters.

Disposable filters

Well most homeowners know there is a filter somewhere in the HVAC system--sometimes they forget about it till things don't work so well. I've had some pull right into the blower of the furnace because they were coated with hair and dirt. Other times on service calls, the homeowner doesn't have a clue where it is. We'll cover placement in another post.
Are the cheap 99 cent filters effective or not?
The fiberglass filters priced usually around 1.00--2.00 will stop most large particles, hair, large drywall particles, and household dust particles. However all heavier finer particles go right through.
For instance fine powdery dirt, pollens, molds, yeast spores go to your HVAC system, and of course gather on ducts, coils, heat exchangers, blowers, etc. The cheaper filters also pass the dirt through when the are full. These need to be changed every 30 days at a minimum.
Next time we'll look at the pleated types.

Well it's been a cold week here in Missouri, finally in the 40's. Spent a lot of time in the office. I had to clean our air purifier and while the parts were drying I noticed I was sneezing more and my eyes were watery. I guess the machine is doing it's job. Send me your indoor comfort problem, let's see if I have the answer. Next time we'll look at indoor disposable filters.

With the cold weather we are indoors most of the day. How is your indoor environment?

Cold Office Warm Office

Did you ever have those areas in home or office that are too cold in the winter and one in the other side of the home or building is stuffy warm?? What is the cause of this? Can it be solved inexpensively? Can it be prevented?
The answer of course is yes. If one knows how the dynamics of a system is supposed to work. It really begins with some simple air flow design and attention to proper layout.
The comfort of our indoor environment affects our attitude, productivity, and in most cases our health.
A few quick pointers for the rest of the winter:
1.-Check the filter of your comfort system--change them no less than every 60 days.
2.-Make sure return air grille is free and clear of blockage or debris.
3.-Make sure all supply air registers are open and unblocked.

Till next time.
