Re: In Need of a new Heat Pump and outdoor A/C

OK, here's the deal: The water heater has to move. It's a good idea to have a water heater inside a closet. Besides you will need the space for a new a/c unit.

But we need more information from you, like:

- do you have a garage?
- where is the house located?
- is the water heater a natural gas model? check the model number again.
- how many live in the house?

As far as a/c size, you will need to have it assessed and determined by the a/c contractor. 15 seer will give you a nice quiet unit.

Thank you for answering my post.

- do you have a garage? - No

- where is the house located? - Richmond, VA

- is the water heater a natural gas model? check the model number again - The heater is natural gas model #DS140S6EN10 designed for closet installation.

- how many live in the house? -2

Thank you...

Oops, I wanted to say that having the water heater in the closet is NOT a good idea...I hope your water heater T&P valve is extended to the outside and the water heater has at least a pan under it.

Anyway, a 40 gal water heater is big enough for 2.

If you have no garage, then do you have a basement? I'm trying to see if moving the water heater is possible (not a cheap solution). If not, ask about a narrow furnace from Rheem. I know they make them to fit tight spaces.

I'd look at smaller HVAC units. I don;t think the indoor units are significantly larger. The coils are a little bigger but not a lot. To minimize size, make sure you get a load calculation done and install the smallest unit possible. You could also invest in better insulation and sealing up air leaks in the house by getting a home energy audit and finding them.

The temperature imbalance is typical in a 2 story home that doesn't have zoning. Adding zoning is pretty expensive even if the main trunks are accessible. You'd need a 2 stage AC and on top of the zone controls.

However, you might be able to minimize the difference. Typically a house that is warm in the summer upstairs is also warm in the winter as well. IF it's also old in the winter, then you are short on airflow upstairs.

ALSO... upsizing the AC to fix the imbalance will actually make it worse. Smaller equipment heats more evenly because it runs for a longer time. I'ts estimated by some that 1/2 the homes in the US have oversized HVAC equipment.

A 2 stage furnace will also heat more evenly and s worth the money in a cooler climate.

DO oyu have a dual fuel system (heat pump & gas furnace) or a heat pump and air handler?

Finally, to improve airflow upstairs, you can install higher quality supply grills on the upstairs registers. They cost 2-3x more, but have better throw (air distribution) and less resistance. So you'll get more airflow upstairs. Atlanta Supply is 1 place you can buy them ******.

If your duct is designed right you should be able to get air to the second floor as the air handler is on the first. How does the 5' of your closet run, parallel or perpendicular to the wall it's in? More than likely it's perp. which means it must be a b_ _ _ _ _
to service, I Know they make air handlers at 21-22 inches so you still have 14 left over not counting the doorway which is more than likely 29 leaving 7. Still more than enough to get it in the closet. If you are getting air with no heat or cooling it may be time to upgrade, as motoguy says a load calc is important in order that your system runs correctly. As dj says you should move one or the other, what happens when the one in the back craps out, no room to get it out without removing the one in front.

Thanks again for answering my post. I appreciate everyone's input:)

I have a First Co., Aquatherm Combo Heater with air handler.

The 5' of the closet runs perpendicular to the heater and hot water tank. Both are on the 3' wall side by side.

No basement, my house is built on a slab. I have a shed that is several feet away from the house, no upstairs registers/return vents.

No upstairs supplies or returns?? Well no wonder it's hot during the summer and cold during the winter. :rolleyes:

I need a new Heat Pump as well can anyone recommend the best one to get?

Re: In Need of a new Heat Pump and outdoor A/C

www.furnacecompare.com/heat-pumps, this seems like a pretty good site but beware of the reviews that only have one posting. Carrier is a good system but with any Manufacturer there are bottom of the line and top of the line. If I was to go with Carrier I would buy the Infinity System, pricey but a very good piece of equipment. The only problem if I remember correctly is that the air handler would have to be replaced also as they have low voltage communication wiring as well as thermostat wiring, the condenser has to talk to the air handler. The coil or air handler in the 22 system should be replaced as the pressures in a 410 system are greater and designed for this. As for replacing the lineset there are flushing agents that that will clean these. Good Luck:)

no upstairs registers/return vents.

I had the same eaction as Sten about no upstairs registers & return . . . I can't believe this was approved in 1988 . . . I live in NoVa, and the state government is not impressive and the local is only a little better.

In the summer, how are you cooling the 2nd floor ?? I think the HVAC design is so bad that you'll need Mike Holmes to start tearing down parts to install a return and some floor registers on the 2nd floor. It doesn't seem that it's an equipment problem. How about room or window mounted units (they're unsightly though)

From reading TOH posts, I've learned you need a return on the 2nd floor: (1) during the summer the hot air needs to be drawn away; sending cool air into the space is not enough, and (2) you're getting conditioned air (cold or warm) in the 2nd floor through the staircase cavity ??. So I have to ask, are you sure ?? The other possibility is that the Builder skimped but the inspector would have caught such an obvious blunder and I can't see this plan complying with habitility code.

Your utility closet reminds me of a 1,200 2-story townhouse I once had in NJ built in 1976. Boy, the utility closet was tight (smack in the middle of the TH), forced air A/C & gas heat plus water heater. Not enough height on the combined A/C & air heat system (main trunk duct) to retrofit a humidifer so it was desert dry in the winter.
