Don't replace anything without a "manual J" first being done. This is how you size the unit correctly, who knows if it was sized right to begin with.

No Comfortfakers in my house.You might want to look into coated coils on the outside unit.Local codes change all the time can't comment on the tonnage issue, but I think you have to have a manual J...

+1

Pricing isn't allowed. My $.02 is change out the entire system, with the savings on newer high efficentcy equipment it will pay for itself in no time.

All is normal.

You probably have enough"slop" (by rerouting)in it you could pull enough out to get 1'-2' out to make your connection.Just my 2cents.

It is supposed to match the outdoor unit tonnage wise.That way when the different calls(heat and cool and fan only) are received the unit runs at the properly sized speed.

+1 on it needing a valve. No signs where the charge was blown(no oil).

Are you referring to make up air and not return air?

What do you intend on hooking the dehumidistat to?

So what is the equipment size and what does the Manual J say the BTU's call for?

What size did your HVAC guy recommend? Get that size.

NO NO NO ,tell them they need to add a hi/lo vent in that room.

To add to what was stated above, the less air moved across the coil the less heat removed. The less heat removed it has to go somewhere and that would be back into the home. Guess what, it has to...

Find the leak first, somone could replae your equipment and the leak may be in the wall in a lineset. Get a good tech to check it out.

You will need to have someone build you a 100% outdoor air unit, as mentioned above aon builds one. But in my opinion they suck. A 5 ton sytem with a 3 ton blower should do the trick, now with that...

This is not DIY, get a qualified person to look at it.

If your Vent Stack(flue pipe) is 2" PVC pipe it will produce water in the heating mode.

So how do you like what you have? If you are happy with it stay with the same type, if not change.

How hot is the attic getting, could be heat intrusion. May need an attic exhaust fan, how old is the home?

Sounds like it is/was frozen up and water is dripping from the ice onto your filter. Could be as simple as a dirty coil or filter causing it , or could be numerous expensive items. You need a pro to...

Is your lot #191 ? They maybe gave you the wrong #'s? Upstairs is way off in my opinion.

There are numerous possibilites of what it could be. Get a pro out to look at it,could be simple(tstat issues) or a little complicated. Or just set up to run that way. Without any numbers I can't...

Make model and serial numers would help to answer your question better.

Amp draw on the compressor?

The hot surface igniter itself should never be touched ,it should be only handled by the ceramic base. The life of it is reduced drastically if you touch the "glow" portion of the igniter.

The only, and I mean only draw back I see with a 1 truck company is the response time when you need it. If he/she has installed a bunch in the course of a year and for some unforeseen reason there...

No, if you are after lower utillity bills keep what you have. Gas WILL cost you more to operate.

1 cool 3 heat to get the most out of it, or at least 1 cool 2 heat to get almost all of it's capabillities. I would be happy with 1c 2 h and have the (2nd stage heat on the furnace) come on after so...

First without the model number from your indoor coil (which I doubt is 13 seer) I can't say you will get 13 seer out of the new outdoor unit, I know you won't,#4. #2 seems to be the best from what...

He is probably reading from leg to ground/neutral which would be 240 across the 2 hot legs.But not sure, he is in over his head though.

what ever size they give you, make sure the generator has a "line conditioner" to clean up the dirty sine waves so it doesn't mess up any and all electronic circuit boards you might have in what ever...

do you have carpet in the house, if so is it dirty/discolored around the walls and at the walls going up any stairs you might have? If so it is under negative pressure. You will pull air from where...

Where do you live and is the heat on? could be the humidifier coming on, not sure without more info.

Your heat cool diff. is the dead band between them going bach and forth from heat to cool in the auto change over mode. Not the temp change from cylcing on and off. You could try and have your Cycles...

Does the unit quit heating when it freezes over or does it still heat? Maybe normal.or sensing bulb isnot in the correct place on the coil or just bad.

what causes that is a loose connection, with a loose connection you have resistance,with resistance you have heat,with heat you melt/burnstuff up.

Lineset sizes would be nice too.

what size duct is behind the filters ?

Glad you could help yourself.

First question is how does it perform as it is? Ductwork design is an art/science. With that said the person designing it can do a killer job on paper, but when on the job the builder can shrink...

If you can afford the install cost GEO Thermal would be the way to go. It's pricey though.

Self portrate, shot it with the iphone.HA HA.

Has anyone tried to look in the ductwork for blockages(esp. if flex is used)? That would be better than exploritive surgery on the sheet rock.They have "snake" type cameras that can be fed into the...

KLS, he states the unit runs just the strips are in delay. If you have no O/D stat it will run a predetermined amount of time before the strips come on, this is to see if the pump will satisfy the...

If it aint broke, don't fix it. What the company/tech told you sounds good.

Is there a gas water heater in the closet also?

Do you have "energy management"in your area from your local power company?Sounds like they are cycling you off during peak times to save power.

If you elect to go with an ERV go with one that has "green wheels" they will help dehumidify the air quite abit going into the home.And the crawl space fix you are planning is the only way to go in...

steam type in the supply duct.
