Ok
How many techs have been out to look at it?

It’s not that difficult!

The last thing you want with a heat pump is changes in temperature. Set it and forget it!

0 - 30 PPM No Display

Didn’t we all

I would that contractor off the list.

There all crap with different issues.

I Like Hoshizaki

Wait until tomorrow and call the factory.

Installed and sized wrong!

Flex need to be pulled out, Large straps or saddles for supporting it without crushing it, Long radius bends On and On

It would be cheaper and easier to rip it all...

Don't bet your life on it, And you are!

Detectors that our government requires are UL2034 listed. They Will Not Alarm until 70 PPM Co is achieved for a minimum of 1 hour and up to 2 1/2 hours....

Fun with Flex!!!

Is the basement all flex also?

Flex is a cheap way of installing equipment. Not a bad product IF installed and sized properly, this isn't.

To correct your issues wont be...

Personal Question. What size tubing and how long on that loop?

With everyone being busy 5 figures isn't out of the question!

I'll A S S U M E .................... Oversized Equipment on undersized ducts. Probably a lot of flex, cavity's and panning for...

Yes

Also Exterior

Split level leave a lot of options. Can you post some pictures? Id rather see 2 systems instead of zoning. Most contractors cant get single ducting correct.
Where on the isl of long?

For the Mini Split thats a single head model. A small duel zone can be installed for the 2 bedrooms.

As for the central unit replace the indoor and outdoor unit with a matched set. Pressurize the...

This makes no sense!

Call a contractor.
The switch was doing its job.
You need a tech with Knowledge and the test equipment!

There are a lot of ways to control this but not on this site.
Get a contractor to install relays.

Too expand you need a “Clean” sine wave that only better gems produce. This clean sine wave is needed anytime a computer is on the circuit. 2 of your 3 items on the list use computers.

The static you read at the stat is what it’s being told to run at. It cannot read actual.
Block off your return the # won’t change.

So what changed between last winter and this winter?

How do you know the 4KW heaters aren't on?

Remember Insulation only "Slows" the transfer of heat. the center of a floor above unconditioned space will always be cooler then rest of the structure. Nothing wrong with electric under floor heat...

Is this the same system that you want the most configurable thermostat one can buy https://hvac-talk.com/vbb/showthread.php?2225682-What-is-the-most-configurable-thermostat-one-can-buy.

So what...

Contact your local union. http://www.ua.org/locals

Also contact Flanagan Mechanical in Phili. Hes a member here.

Sorry but yes they do. That fitting should be mounted vertical.

Sad but probably true.

Find a more qualified contractor.

What a $hity but........
Profitable game plan.

Did you measure across the switch?

And most apartments are oversized.

After 35+ years start from the beginning
Manual
“J”
“D”
and
“S”

You cant use your stat for that. The t-stat only shows what its calling for, Duct work, supply and return grills and your filter all affect the actual static.

Block off the return the stat will...

Ask your building departmeent.

6 CFM's is nothing. Insulation swelling is a lot more.

Unfortunately the contractor will probably do nothing to remedy this.

Good Luck

Tell this contractor WE said hes full of it. Contact your Building department and ask them if duct sealing is required.
Ask him about Mastic for sealing ducts, required in most judications.

He...

and they probably never checked TESP or ran a combustion analyzer.

Hang in there. Its a shark infested pool but you'll survive.
As been said apply for pro.
As for your EPA card that's virtually worthless anyway so block out the 1st 5 #'s if you want.

If the duct work insulation is "Swelling" then there are some serious air leaks in the duct system. If the ducts are in conditioned space not much of an issue, if in uncondationed space then yes a...

Were any measurements taken? Air Flow not physical? You need a contractor that will perform a Total External Static Pressure (TESP) test. With that they can tell how much air the ducts can handle and...

As a retired Operating Engineer...................Good Luck! :cheers:

Find a qualified tech.

NCI Certified.

I don’t go by the factory charge.
8 Oz is difficult to weigh.
