New matching evap coil was installed?

ACX series is low end.

Post back.

I would suspect of any HVAC company who would install equipment in a customer's home without written permission.Are they that desperate for work?

Does this company have an HVAC license? I am going to assume they did not file for a permit and no inspection will be done. I hope this works out well for you.

A new evap coil was installed. I'm aware now that ACX s considered low end, builder's grade. This is why I wanted the service contract and extended labor warranty. I tried my best for 5 years each; he would only do 3.

This company does have a license and is actually one of the most highly rated companies in the area for installation and service. I was very surprised this happened.

And what about the Permit?

They said no permit was necessary.

My opinion is they were trespassing and installed something you had not given them permission to do at their own peril. You could have told them to come remove all of it at their expense, but you appear to have agreed to accept it when you asked them to come back and do additional work. I hope you got something you will be happy with.

The question is what do you think? Would you have bought this system at this price, are you now satisfied with the installation?

As the previous post stated you may be in legal limbo when you had them return to fix a problem. Have you signed anything; have you given them any payment?

Generally, I feel that most thinks in life are negotiable, in this case itâÂÂs either I get everything I want or you can take it out or they can just remove it and pay something for your inconvenience.

YouâÂÂre in the driverâÂÂs seat. You could say that you gave them a chance to fix the problems; theyâÂÂre still not fixed so take it all out and get lost!

That is if you havenâÂÂt signed anything or made any payment.

Imagine where this installer would be if he installed this in the home of a lawyer. HeâÂÂd be hold up in a cheap motel 3-states over!

How did they gain entrance to your house?

I'm not entirely dissatisfied. We were planning on buying a Goodman 13 seer compressor, and the Lennox is in the same ball park as far as I can gather. The company has been very cooperative and is doing everything they can to make us happy.

I know I had the option of asking them to take the system out and hit the road, but we have a 4 month old who isn't sleeping well with AC running. I'm not sure we could have gone days without a compressor while we waited to have another installed by someone else.

With regards to the board in the furnace, do you think it was coincidence that it broke on the day of the install or could they have done something that broke it?

Weedmeister, on the day of the install the didn't go in the house. They just walked through the gate to the backyard and accessed the crawl space there.

The installation was done without entering your house? The contractor installed a new condenser without turning it on from the thermostat to see if it would work? Did they have to enter the house to change the evaporator coil? Did they flush or replace the line set?

"the furnace could no(t) communicate w/ the thermostat".

It seems too much of a coincidence that the thermostat stopped communicating with the furnace on the day of the installation. Mostly likely the installers caused the problem. It may have been a wrong wire connection or setting a DIP switch incorrectly. I doubt it was damaged, but then again they may have sent a novice team to do this unauthorized installation.

Correct that no one entered the house. They did replace the line set and the evaporator coil. For some reason, they paired a 3.5 ton coil with a 3 ton compressor. Any reason you can think of for them to do that?

Seems too much of a coincidence to me, too, that suddenly there would be a problem with the furnace blower when it's been working fine. Unfortunately, I just don't know enough about the system to ask what they did during the install that could have killed the board. Is it typical for installers to pay for their mistakes when something is damaged during an install? That is, if you can get them to admit fault.

Need your opinion for an issue we're now having with this install.

We noticed that we're waking up in the middle of the night feeling really hot and sweaty, even with the thermostat set to 73 degrees F. I looked at my hygrometer this morning and the relative humidity in the house was 55%. I started tracking relative humidity throughout the day and it sat right around 58% with the thermostat set to 73 degrees.

When the service tech installed the new board in the furnace, he mentioned that he would increase the blower speed to high. The reason being that the system would operate more efficiently.

After doing some reading, this seems like it could be the reason for the high humidity. Correct me if I am wrong, but a fan speed that's too high does to things. Cools the house too quickly, which decreases the time that the system can remove moisture from the air. High fan speed also decreases the temperature of the coils so that there is less condensation. Is there any other reason the new compressor, line set, and coil are dehumidifying very much?

Blower speed in cooling should be no more than 400 CFMs/ton, in fact you could go lower. This will remove humidity more effectively. Also AC mode should be in auto, not fan on continuous operation.

Do this and then run your humidity readings.

Thanks, tigerdunes. I'll have a tech come out and check the blower speed. Do they have a device they can use to verify the speed setting? Would I be out of line asking them to set it to 375 CFMs per ton or should I let them use their judgement?

Just for some more info, here's the indoor and outdoor temps, RH, and dew points.
