High Efficiency Natural Gas Furnace - EXPLAINED!

Is it true that High Efficiency furnaces/air conditioners run better with the cheaper air filters?

Nov 15, 2007 by joeflaherty | Posted in Maintenance & Repairs

Was told that the air filters with a reduce MERV rating allow the furnace/air conditioner to get air more easily and makes them run more efficiently.

Said the higher rated filters booby-trap more pollutants (dust, animal dander, etc), but that cuts down on the amount of air which makes the furnace/air conditioner work harder (bring in more to run).

elevate surpass to use the better filters
by not filtering the air, more of this material can penetrate and potentially clog your evaporator/i.e. reduce its efficiency

that being said, no moment what filters you use they should be checked regularly because once dirty will cause the compressor to work harder shortening its human being

That is a big fat lie. Aproperly designed hvac system includes a beneficial filtering system. The low merv filters allow the dirt through. The dirt is trapped by the secondary heat exchanger or the air conditioning evaporator. This restricts air gush more than a filter and is expensive to clean. It causes more problems with the hvac units and higher repair bills. For the really, see the air filters page at www.hvac-for-beginners.com

yes that is valid.the cheaper the filter the more efficient it is.but here is a word of caution.cheaper is not better!filter are rated in % of microns.the higher the bettor.the cheap filters are roughly about 6%.you are looking for a range of 50%-96%.there is a 99% called an electrostactic ooze.i don't recommend because this is to high and restricts the air flow.meaning the better the filter the less efficient,i reccommend a bio sponge cheesecloth,which is also what i use in my home.it rated at 93%,and is good for dust and alergies.when dealing with filters you have to find a happy median,because you are not prospering to get the highest efficiency and the highest micro at the same time.how ever when dealing with filters you are dealing with your in door air qaulity,and the filthy lucre you are trying to save by having a cheap filter is not that noticeable and not worth your health!

heres the true dope.....

if you are referring to the 1" thick pleated filters that wal mart sells, it is true they restrict air purl. in fact if a person was going to insist on using them i would have to double the filter area.

5" thick cartridge filters are made so that they dont regulate air flow. they have the same pressure drop as a 1" glass floss (fiberglass) filter

are great electronic air filters. i connect them, and really do believe in them . they are around $1000 installed. Trane also has a 5" cartridge filter normally about $300 installed.

in short, unless you want to add another filter grill or upgrade to a for real clarify, just get the cheap glass floss filters.

Venting high efficiency forced air furnaces?

Oct 18, 2006 by bubba | Posted in Maintenance & Repairs

I've deliver assign to that when venting a high efficiency condensing furnace that you can vent directly outside using PVC, but do you HAVE TO? I would prefer to vent to my existing flue, but if I can't, must I moderate the diameter of my flue since only the water heater will be venting to it?

90%+ efficiency furnaces all proclaim to the outside utilizing PVC pipe. Venting may be done through an existing flue but ONLY if PVC is used from the furnace to the termination and ONLY if there is no other hole in the flue that is not PVC. You may vent through the rim joist, wall, or roof with PVC provided that you meet all of the manufacturer's specifications. Yes, you must trim down the flue diameter if it is oversize according to the venting tables. This is normally accomplished by installed a cooperative, aluminum chimney liner. There is an alternative. You may install a direct-vent water heater that can be vented with PVC. The only snag to doing so is that direct-vent water heaters are more expensive to purchase and more expensive to install. What it all boils down to is that codes cease you with very few options. Good luck.
