Yes, it would be a new r22 dry unit. It's half the price of a whole new system. I really don't want to spend more than I have to, but don't want to make a foolish move either. I am betting that...

Two contractors have told me the max. life of a HP is 10the yrs. and that it is foolish to put a new compressor on a 10 year old unit. I can have a new HP installed for same price as a compressor...

It was installed in 2000, so the warranty period was just missed.

Would the recent changes in freon regulation affect the availablility of the same compressor?

I have two units that each use the Lennox HP26. The compressor in one unit went bad two years ago and was replaced under warranty. The compressor in the second unit has now gone and a contractor...

I broke down and turned on the AC for the first time today. I noticed just now that the air handler (lennox CBX32MV) is making a gurgling sound and that the drain pan is filling with water. The...

Installer is clueless. I had to show him that I could get the HP to kick on. He automatically assumes it is a bad stat. He has replaced the stat on our upstairs unit at least 3X's when I know that...

I have a Lennox system that was installed two years ago that has never seemed to be function as it should. The system consists of a heat pump with propane back up, but the propane runs 90% of the...

Understood. While not a big fan of government intervention, I manage a civil engineering division in a firm with a huge MEP operation and while I deal with water and not air, I understand that in...

My wife and I had a system installed over a year ago and things have not been right since day one. From set points to bad thermostats,etc. The system quit working yesterday, so I placed a call. ...

Joey83, I'm talking about the large gray pan that sits underneath the air handler. I can physically see and touch the water.

The good news is that the thermostat has been satisfied and neither...

They both needed it, so we'll see if today brings any changes in the ability to satisfy the thermostat. I don't want to keep my house at 69, but if I want 72, I'm hoping it's not too much to ask.

I live in northeastern Maryland, where the temp yesterday and today was hovering around 90. I turned on the ac for the first time yesterday...had the upstairs system set to 74 and the thermostat...

Thanks for your responses!

Yes, we did use the system last season...it was brand new! RH is at 42% right now...my outdoor sensor says it is 97 and my indoor temp is 79, although it is set at 74.

We had a Lennox CBX32MV (with XP13 HP) installed last summer. Seeing as it is close to 90 degrees today, I kicked on the ac for the first time this season and noticed that the air handler is making...

I checked the furnace and it flashes an error code of what appears to be 43. A red light flashes four times with a brief pause and then three times with a long pause then repeats.

2nu-the pipe is plastic. aircooled-the furnace may or may not come on in either em heat or heat mode...it's totally temperamental...one time it works another it doesn't. Some days the system works...

It doesn't work in either EM HEAT or HEAT mode. The furnace comes on once after we restart the system, but then it won't come on again. The filter is brand new...only been in there about a week.

When the system starts back up (if it starts back up), it's the furnace not the heatpump (single stage XP13). I assume this is because there is such a large temp difference between the actual and...

The thermostat is a ComfortSense 7000. It has to be something with the configuration because the system seems to work as long as I keep turning it off and then on again. Unfortunately, I can't stay...

The thermostat is a lennox.

My wife and I had a system installed by a licensed, reputable installer who has installed several systems for my family over the years. Not our only interview and not the cheapest, but seemed at the...

I received 7 bids and the company that we went with was definitely not the low bidder. It's a family-owned company, in business for over 40 years, active in the community, good recommendations, etc....

attic install.

The quiet vents are the flex duct that are run in the eaves and the noisy ones are the rigid ducts. Also, the return that is noisy (almost like a hum) is very close the the air handler, should that...

Any idea what would cause a few vents to be noisy (while some are perfectly quiet) and one return to be louder than the others?

Thanks!

I will ask him also. I just want to be armed with my own knowledge. The system was set up by the owner's son...I'm not sure he even changed any of the factory settings.

I recently had two new Lennox systems installed, icluding brand new ductwork. While I don't have any real complaints about either system, I want to make sure that I am getting the maximum efficiency...

The coolant line is insulated up to the bend in the line (where the black tape ends in the pic). Should it be insulated further...up to the point that it enters the furnace? The copper line that...

be applied only over the tape on the furnace joint or should it be applied to all the taped insulation too?

They also used this tape to seal all the insulation on my rigid ducts! Am I in trouble?

I read in a thread the other day that Lennox does not put txv's on their 13 SEER units. As you can see in the pictures, there is a TXV on my G61MPV furnace which is paired with the XP13 heat pump. ...

and tell me if cold air should be blowing out of the space where the coolant line enters the furnace?

Thanks in advance!

and there is cold air coming from the registers.

Mode = Cool
Fan = Auto

Thermostat is set to 75...indoor temp is 72...outdoor unit is on and running to cool. Why? Is it maybe trying to dehumidify?

The thermostat is the ComfortSense 7000.

Thanks, Socal. He did check the outdoor unit and said it was running perfectly. He was reading the programming manual so he did check the L terminal, although I am not sure if he disconnected it...

My new comfortsense 7000 thermostat has an error reading "HVAC Error Detected". My installer checked the L input and everything on the HP and furnace checked out fine. Installer was on hold with...

What is the required distance from a window or door for direct vent gas?

thanks again!

Thanks, Ryan. You are right, we are getting the MPV...variable speed. We have an old house (dirt floor cellar) and are hoping to conserve space for possibly finishing the basement at some point. ...

We are having a Lennox system installed this week. We are getting the G61-36B-45 with coil CX34-36B-6F. We are also having two XP13-024-230 heat pumps installed, one to work with the furnace and...

Could someone please tell me if the following Armstrong combination is a good one? The ARI website is a bit too confusing for me, the non-HVAC professional :) I would love to know what the actual...

Is it worth spending the extra money for a high efficiency furnace if it is going to be used as back up?

We live in a two-story, 100+ year old house in northeastern Maryland and are looking at...

thanks guys, you've been really helpful. In reference to zoning controls, are they available for heat pumps and oil furnaces? I've spent all this time getting quotes on oil and now I am starting to...

okay, now I'm thoroughly confused. I'm not real clear on the ARI combination certification. Is there a possibility that the sucky numbers that you listed would somehow be different for me? I'm...

Thanks gary_g and tiger dunes.
