When I decided to buy a new car last year I took my infrared thermometer and hit each different color - black was 145*, dark blue 141, red 138, light blue 125, white
112. I didn't buy black, red, or...

It was brought to my attention today that if a homeowner sells his house the existing parts warranty on the equipment for both Goodman and American Standard drops to 5 years on parts and the...

BAD IDEA! Your existing unit probably uses R22 as refrigerant, and everything today is R410a. In addition, the new unit will be a higher efficiency and should have a matching coil.

Getting back to the origional problem - you say you are having problems, and obviously your installer has not corrected them to your satisfaction. The system is a rated match, you have purchased an...

If you want to rewrap you first need to drop the metal trunk down to a workable level. If the trunk is still strapped to the floor joists you will never get a good tight seal and will have the same...

Pstu, you might well be right on the money and it is a piece of cake. My point is that I want the manufacturers to have the information availiable in case we find it is needed.

First of all, this tax credit has nothing to do with the stimulus, this is a tax credit that was passed last year for the year 2009.

Secondly, this has nothing to with filing a normal tax return....

I hope everyone is aware of the tax credits that are availiable for 2009:

$300 for 95% furnaces and boilers
$300 for 95% tankless water hearters
$300 for 15 SEER/9 HSPF heat pumps

Coleman and Miller both make furnaces for mobile homes. If you install a furnace that is not mobil home rated, you void your homeowners insurance contract and the installer is liable for any damages

We all know that 410a is mankinds savior because it is so environmentally friendly. I am sure soon there will be a press release from Dupont saving how

High efficiency and 410a systems are creating situations where the breaker size and wire size can be smaller than the existing 15 year old R22 system.

Dual fuel (heat pump with oil backup) is an excellent way to go and should save you a great deal of money each year in both heating and cooling. You should get at least a 14 SEER unit and use...

Hot Rises, cold air falls, simple as that. You need to be able to ballance the airflow accordingly to send more heat downstairs in the winter and more cold air upstairs in the summer.

Here is a better solution - run a seperate zone off your boiler and install a First Company air handler that has a heat pump coil and a hot water coil and use that as your backup. The thermostat will...

The true purpose of ductwork is to "WASH" the window with a thermal barrier and keep the outdoor temperature outdoors. Any other air is wasted.

there are dip switches that control the air handler speed. Get your installer to look in the owners manual and set the switches acording to your needs

Mark is 100% right.

With the exception of Unico systems, why would you cut a round hole in the first place. Ductwork should be rectangular so that the air "washes the windows" to keep the outside...

variable speed also allows you to run the fan 24/7 and get continuous filtration. v/s is the only way to go

It all depends on your utility rates. Today's high efficiency heat pumps are FAR superior to the old ones.

You can also go dual fuel and have the best of both words.

If you call tech support for the blower manufacturer they will tell you where to put the fan for best performance. I did it and got 50% more air when I placed it where they suggested ( 2/3 of the way...

As mentioned earlier, make sure that you get the right size equipment - if the contractor won't do a load calc, get one that will.

The variable spped units are 2 stage, which means much of the time is runs at 1/2 speed. Make sure that the contractor takes this into account. I have seen one case where the furnace high speed size...

Does anyone have links for documentation that shows that a manufacturers warranty is voided if the matched coil is not replaced with a new outdoor unit?

Sorry, Bubba, but I am serious. You would be amazed how many poorly connected start collers I see. I don't install, but am a thorough salesman that actually checks ductwork, and I find amazing leaks...

my experience has shown that many leaks occur where the start collar is attached to the trunk - if you use dampers, it can be quite difficult to bend the tabs in completely
