Does humnidity affect an a/c unit's ability to cool and therefore run times? It's less than 90 degrees but humidity has heat index around 100. A/C (2.5 tons for each floor) has been running three...

Which has a higher MERV rating?

Saw a washable hogshair filter that claimed MERV 4 (would not have thought it was that high) and was wondering if washable hogshair provided more filtration than...

With a strike like this, does it matter if the unit is on or off?

Its a Bryant 383 upflow 2.5 ton with 10 inch ducts. The filter is in a filter grill right before the furnace

In another thread someone wrote that the smaller a filter is the more you need to worry about restrictive air flow. What's considered a small filter?

I've got 16x25 and use the cheap blue...

Was wondering if the no. of people in a house affect ability of ac to drop temp. My mom had a party with about 15 people this afternoon and downstairs barely got below 80 and the downstairs ac ran...

My filter seems to catch more dust when heating during the winter than cooling during the summer. Is there something about heating that creates more dust or causes the filter to catch more dust?

If the AC is not being run when it's hot outside (say 85-90 degrees), does opening the windows mitigate heat buildup in the house or cause the house to heat up?

Have a crazy elderly relative who...

I have heard that heat pumps cost less to run in areas with moderate winters. Assuming the strips never come on, the heat pump still has to run the condenser to operate doesn't it? If so, shouldn't...

are refrigerant lines to inside coil supposed to be insulated?

would looking at the condensate in the clear plastic tube that drains it away give an idea of the cleanliness of the coil?

After reading a lot of posts here, I have pretty much decided to use the cheap blue fiberglass filters - I know there is a difference of opinion.

However, I have noticed that the cheap blue...

when I first turn on the a/c, if the a/c setting is less than 4 degrees cooler than the temp reading on the thermostat (one of those old fashion dial thermostat), there is a few minutes delay in the...

I was wondering if it makes a difference where the inside coil is located in the air handler.

Typically I see the that the air flows through the filter, then the blower motor blows it over the...

54 year old benching 225 - that's pretty good.

By the way, how much does a air handler weigh? I was wondering if there was any risk of breaking those pull down attic stairs - they look kind of...

What's a better placement for the outside compressor - full sun with with no bushes/trees to restrict air flow or shade from low trees that might limit air flow a little?

My condenser just sits in...

Thanks - so most residential is a split system correct?

I see the term "split system" on posts from time to time but don't know what it means. Can anyone give a brief explanation - just curious

Real interesting discussion. Although there is some disagreement as to whether whirlybirds are better than electric fans, is there a general consensus that either one is better than those square box...

Do those wind powered whirlybird turbines (looks like a mushroom) suck as much air out of the attic as electric powered fans?

I have a two story home and the upstairs is obviously hotter than the downstairs. Without running a/c, probably a 6-10 degree difference depending on outside temperature - on 85 degree day, the...

Thanks for the feedback guys. The furnace is located in the basement and that gets humid with our Ga summers

I did not bother to call the original installer since it had a one year parts warranty (20 on heat exchanger) - it was a Bryant 383 upflow by the way. Don't know what all the tech did since I...

Tech came out and replaced the hot surface igniter - it had a small crack in it and some white residue where the crack was. The home is only 3 years old. I was wondering if 3 years is typical life...

When I turn on my heater, I can hear gas but see no flame in the furnace (so I have no heat). Any thoughts?
