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

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

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

beat 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 effectiveness

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

That is a big fat lie. Aproperly designed hvac system includes a most luxurious 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 stream 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 accurate.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 wagerer.the cheap filters are roughly about 6%.you are looking for a range of 50%-96%.there is a 99% called an electrostactic drain.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 leach,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 flourishing 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 cold hard cash you are trying to save by having a cheap filter is not that noticeable and not worth your health!


heres the legitimate dope.....

if you are referring to the 1" thick pleated filters that wal mart sells, it is true they restrict air surge. 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 delimit air flow. they have the same pressure drop as a 1" glass floss (fiberglass) filter

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

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

What is the best brand of furnaces and air conditioners?

We are structure a house and would like to know what is the better brand of furnace and air conditioner? Bryant, Train, ect. Also what should it price to install heat and air in a 1800 sq foot new construction home. We have 1800 sq feet upstairs and a boardwalk out basement (1800 sq ft) that will also need heat, no air. Any input would be helpful.


We purchased a York CH/A about 4 months ago..... the ducts and skin unit were already established, so I can't really be of any help to you on that note, but I can tell you that the install and cost of the lining unit without the rest ran us $3,500 and we have a 1700 sq. ft one story home, and we purchased the one with the 97% eff. rate.. We leaning it.. it is quiet, and keeps our home comfortable.. andthe sevice man, informed us that it is one of the most requested around our area, due to the eff. amount, the great feedback, and the rare need for repairs...... they haven't had any compliants, and we are also another satisfied consumer.

We used to have a Trane , and it didn't work well at all.. we would have to repair and replace parts, at least once a month.. (no crack) .. it may have just been a bad unit, but we will never do that again... Our outside unit is a Bryant, and we have had it for almost 3 years.. no issues at all.....

You ought to be proficient to contact a CH/A company in your area... most will do a free estimate!!

Good Luck!!
