Hydronic Heater/AC help

Post  lbol on Sat Feb 26, 2011 2:05 am

My heater and AC is not working. The water temperature can be controlled normally, but when it comes to the heater/AC, no hot/cold air is coming out. I need help with finding someone who can fix it. I called in people from several companies, but they said that they have never worked with the water heating system and could not fix the problem. Please advise. Thank you very much!

So it worked before but stopped recently and it's not blowing any air?

If you search through the threads there may be some referrals from residents. You can also contact peachtree and they will definitely have a referral for you.

It is blowing the air, but the temperature of the air is not changing when I am trying to adjust it. I called Peachtree before and they could not help me. They told me to find a specialist.

You confused me initially by saying no hot/cold are was blowing. So the fan is blowing air, you're just complaining about the temperature?

Are the valves for the hot water circulation open on the connections to the hot water heater? If not, both need to be open to get hot air.

Who did you speak to at Peachtree?

I am not sure if all the valves are opened. There is hot and cold water in the house. It is the heater and AC that are not working - the temperature cannot be controlled. I do not remember the name of the lady at Peachtree that I spoke with.

The HVAC and the water heater are connected. You need the valves open to circulate hot water through the system. That is why there may be no change in temperature. You can have all the hot water you want but if the valves are not open its not getting to the HVAC.

You need to speak to Veronica at Peachtree, otherwise they won't know who to recommend to you.

Go to your hot water heater, there should be two pipes with yellow handles connected to them. If the handles are perpendicular to the pipe the valves are closed. If they are horizontal to the pipes, then it's open.

All the valves are parallel to the tubes. I will call Veronica on Monday morning, and let you know the outcome. Thank you!

I called Peachtree and spoke with a lady responsible for the Villagio community (Veronica was not at work). They gave me the contact information of two companies. After calling the company responsible for water heater, the company representative told me that since I have hot water, the problem must be with the furnace, and not the heater and therefore, I should call someone else. I did not call the other company that the Villagio representative mentioned since they have very bad reviews online, but called another company instead. Their technician came in the morning and turned the water temperature to the maximum setting ~170 degrees Fahrenheit. After an hour and a half, warmer air started to come out. We told him that this is not acceptable, but he persisted that this is how the system is supposed to operate. I have several concerns. First with the hottest possible water temperature, we cannot comfortably wash the hands and cannot use the dishwasher since 170 degrees F. is significantly above the recommended temperature. In addition, waiting for at least 1.5 hours to warm the house seems to be too long.

Please advise. Is this a "normal" problem in the community? The technician said that if we are not satisfied, he will bring the supervisor to analyze and address the problem, but we need hard facts to support our case.

Thank you very much for your prompt responses and help in this matter. If you have other suggestions, please tell them as well.

wow, 1.5 hrs to warm isn't normal. The warm air coming out of our unit isn't instantaneous, but I would say 5 to 10 mins is normal for us.

Water heater yellow handles have to be in correct position for heating and cooling system to work

Post  Italia on Fri Mar 11, 2011 5:10 pm

There are two yellow handles on the pipe along the side of our waterheaters. in the winter you need to have those in the on position so the hot water runs into the heating unit.
In the summer you need those handles to be in the off position so hot water is not running through the sytem.
One position is handle up and the other is handle at a right angle.

This is something no ones tells you about when you buy a unit here. I did not know this for 3 or 4 years and so my AC never cooled my unit.

mine also is not working

Post  john on Sat Dec 24, 2011 4:41 pm

I also get hot water in faucets, the two yellow levers are vertical, but the unit blows unheated air. It looks like the water pump in my hydronic unit is not working. Does anyone have referrals of reliable/reputable companies which know how to fix these units?

No need to pay someone regarding heat/AC

Post  Italia on Tue Jan 03, 2012 8:27 pm

You just have to move the two yellow handles on the waterheater to OPEN for heat in Winter, and to CLOSED for AC to work in summer.
That's it!!

Down stairs heater is releasing kind of cool air

Post  Chandu on Thu Feb 02, 2012 9:27 pm

I checked the discussions regarding the heating system. Unfortunately I couldn't find the correct answer. We do have split AC system in our unit. Upstairs heating and cooling is perfect in winter and in summer. Only problem is downstairs heating....I checked the two yellow vales to see what direction they are, both are in two different direction. Compared with neighbors same kind of unit, their valves are in different place and different direction. I need help to fix the heating system.
Any help is appreciated.
Thanks,
Chandu
