In reviewing your previous posts, you are a homeowner, and therefore this thread needs to be relocated to the “AOP Residential HVAC (Beenthere Zone)” Forum.

Please take note of this new location...

Yes it can be replaced.

If they are a good company, I would hope they could easily make a determination if it is a bad blower motor, a refrigerant leak, or something else.

Getting a salesman instead of a technician is...

Those are model numbers.

Depending on how it is set up, the air handler can have an airflow in heating (aux heat) more than double what you would have during cooling.

A contractor should be...

I agree with "pecmsg" in that the pressure switch's (PS) could be doing their job, and just changing them may not solve the problem.

There are tests a contractor can do to see if the PS are...

It could be failing blower motor, but without troubleshooting the issue, we are only guessing and that is not in your best interest.

Your best course of action is to have a contractor investigate...

There are some great tech support guys out there that are familiar with article 440.

Then again, you would be surprised how many techs out in the field don’t have a clue what article 440 is, and...

You got your wish.......

Welcome to HVAC-TALK.

We would appreciate it if you would not bring back to life 19 year old threads (2005).

If you feel your point of view is relevant to a particular...

We don’t usually recommend throwing parts at a system unless those parts have been tested to see if they are out of specs.

It is also recommended that when a new capacitor is installed, it is also...

I moved your thread to the "AOP Residential HVAC (Beenthere Zone)" forum as this is the only place where homeowners can ask non-technical HVAC questions and seek advice.

Please take note of this...

Sweet!!! Back to normal.

You Control guys rock!

Because your profile states you are a "Facilities Manager/Mechanical Engineer", I moved your thread to the “Tech to Tech Chat - Commercial” forum. The AOP forum is where business owners with no HVAC...

Easy now. If you can't be respectful, please do not comment.

From time to time we all miss the date when threads were posted - don't worry about it.

Just for your reference, "schoust" hasn't...

Correct. This can cause condensate (water) to get trapped in the pipe should the pipe start to run uphill in another section of the flue.

Trapped water can cause nuisance pressure switch issues...

It is still hard to tell from your picture which section of pipe the "level" is resting on.

The pipe appears level from the photo, but one end of the "level" is resting on the zip tie.

So if...

Welcome to tales of PHM.

Didn't you like the responses to this same question you got in the Pro Commercial forum - https://hvac-talk.com/vbb/threads/2269267-Refrigerant-Piping-Sizing-Calculators

If you have follow on...

Sorry for that and thanks for pointing it out. I will also reach out for you and see if we can get it quickly resolved.

I knew many would use that test, but didn’t know it was recommended by a manufacturer.

Thanks for that insight.

Not sure what you mean by a “Pressure Test”. The old Lennox Pulse furnaces were the last ones I know of that had to have their heat exchanger pressure tested.

If you have someone out again for any...

As you stated, we are limited on advice we can give, and you have provided what he needs to know for seeing if there is a call for the fan.

The outdoor fan motor on this model doesn’t use a capacitor.

It is a variable speed motor that is controlled by PWM DC voltage signal from the defrost control board.

Thanks for the clarification.

Can you please clarify if you are a tech or just an equipment owner.

Easy Mr. Engineer…..

I will give you the benefit of the doubt now that you have confirmed your background for me, and move this back to the Tech to Tech forum.

Just know that even in this forum...

This forum does not allow us to assist with DIY repairs, and seeing as you stated in your post a HVAC company installed this blower motor 8 years ago, I would suggest you contact them again to...

Your profile states you are an HVAC/R Engineer, but your questions sounds like you are a homeowner working on your own system.

For that reason, I moved your thread to the "AOP Residential HVAC...

A 60,000 btuh input furnace should have about 900 cfm of airflow (150 cfm per 10,000 btuh input).

Now the best airflow is the one that provides the greatest Delta T and the lowest Flue Temp.

I’m sure this is not what you want to hear……..

I don’t have a answer other than getting the cabinet guys to modify the hood box to accommodate proper venting.

I’m sure it wont be cheap, but...

Post the model numbers.

I wont argue that.

The only way to know that is with thorough troubleshooting, and we can not do that over the internet.

We could guess like your tech, but as you have found out, that is not in your best interest.

If this is a 90% furnace, it sounds like condensate is having a hard time draining.

The vent layout, pressure switch tubing, and condensate trap all need to be examined.

Can you also post the model number of this system.
