HVAC Options? Have quotes.

1234 Views 24 Replies 10 Participants Last post by  Jacksmyname
Hello All-


I was looking for a little help with my HVAC decision for my HT and basement. I have received three quotes from 2 contractors and I am in a quandary as which choice to make. I live in the Philadelphia area and currently finishing a section of my basement for a family/bar room, a HT, a play room, and full bath. The finished area will measure roughly 1250 sq feet.


Here are the options right now:


Contractor #1: Provided me with two options:

1. Install a heat pump with two zones (one for the dedicated theater) at $8600 (14 seer, 1.5 ton American Standard) :eek: :eek: :eek:

2. Add two zones to the first floor gas furnace (again one for the dedicated theater) at $5600 :eek: .


Contractor #2: Provided me with one estimate and did the original install of my two furnaces during my build (1.5 years ago). He did not recommend option #2 above as he indicated that the unit was installed for the first floor. He stated that he would install a third gas furnace (2 ton, 13 seer York) for my house for the basement (single zone) at $7000 :eek: .


A few of my notes: I would lean toward contractor #1 option #2 (add two zones) as it creates less future hassle in my mind should the unit need to be replaced (replace one furnace instead of two down the road). However, he did say that he would be a bit concerned about dropping 2 tons of air into the HT quickly and mentioned about using oversized vents. Now I told him that this was going to be a office space for myself to avoid the “this guy is putting in a expensive HTâ€, I’ll show him with this estimate syndrome that I have read about. I thought that the quicker cool times would be a plus in a HT. Also, in my mind, it would me less time away from cooling/heating the first floor (my wifes biggest concern).


I thought that a new furnace install would run about $5000 but didn't expect numbers of $8000.


I can provide the specs on my 1st floor York gas furnace if necessary. Also, I have the unit numbers provided in both estimates if anyone is interested or a HVAC Pro is in our mists.


As always, many thanks to all those who assist here on AVS. :)

I get more quoutes, I have numbers for a 3rd floor system costing under 5k for a new heat/pump or upgrading the existing furnace
I'd get more quotes. Something definitely seems out of whack with those numbers. I'm hoping you have gas service and your gas furnaces aren't using propane. Propane is so ridiculously expensive that I ripped a brand new propane furnace out after one winter and put in geothermal. Too bad you didn't go geothermal when the house was built 1.5 years ago. For the prices you're getting quoted, you could have for not too much more and had very low monthly bills.
Hello-


Yes, I do have natural gas coming into the house. In fact, it already piped to the exact spot with an open T ready to add where the new furnace would go. They only need an elbow and a few feet of copper.


Anyone else want to add some thoughts? If you were me, which option would you choose (ignoring costs above).


Thanks,

T.Wells

For dedicatated theater and media rooms, a commercial HVAC contractor vs. a residential contractor will serve you better. Commercial contractors have a better understanding of NC ratings, have access to special materials such as insulated duct work and in most cases an engineer on staff. Also, cheaper isn't necessarily better. Just be careful!

I'm doing the exact same ting now. Considering a zoned system but I've only contacted one contractor so far. What does that mean, "for the first floor"? No duh. I think he was concerned about proper sizing for the zone "calling" for ac/ht. The way I understand it, it would be bad to have a huge capacity available but only a small area asking for cooling or heat. What size is your first floor unit? I don't see why you can't zone it for the basement.


Yeah, I'd get more quotes.

Marc,


Thank you for taking the time to reply. Both contractors advertise commercial and residential. From my conversations, I did not get the idea that there was an engineer on staff so I may not have the best folks around. The company who my builder used to install my current system mentioned sending my house plans off to York so the right size unit could be selected so they certainly do not have a staff engineer.


I will continue to look around.


Thanks,

T.Wells

Andy,


My first floor unit is 1.5 ton. My basement should be much easier to cool than the 1st floor and also should heat easier as it is smaller sq footage and also much less air volume. My first floor has 9' ceilings and a two story family room and foyer. Therefore, it may be bad to have too much air in a small area (especially the theater at 15' x 25')


Thanks,

T.Wells

We recently had the HVAC work completed in our 1700 sq ft basement. We had a new compressor and heat pump installed for the basement with one thermostat, all the existing ducts were changed to flex, and where possible moved up into the joists, or along the walls, and the new ducts installed were the same flexible type. 5 supply ducts, and 2 returns, plus when we have finished the basement, they will come back, attach all the register covers, complete the HVAC wiring, and fire it up. We paid a total of $7016.
So basically your 1st floor and finished basement will be the same size. Actually that is perfect for a zoned system. And if the HT is a zone by itself a bypass is installed between the supply and return to keep the airflow up. Or they can use part of your basement as a "dump zone" that will also get cooled or heated with the HT.


We have a 3 ton unit for our 2200 sqft ranch style house. I'm planning on finishing round 700sqft initially then more later. I got one quote so far for a zoned system (main floor, HT, rest of basement) of approx. $4200. I'd get a couple more quotes on a zoned system.
I have a few questions for you.


What presently heats the basement?


Can you post floor plans with duct layouts?


What is the make and model of the furnace?


What kind of domestic hot water heater do you have ? perhaps it could be converted to also supply hot water for heating. Model # and btuh input please.



At first glance I would suggest a zoning system for the first floor and the basement. but a small separate system for the basement might be an option as well, utilizing the domestic hot water or electric for heat and a 1-ton split A/C.

Nothing. It currently is not heated or cooled. I am in the process of finishing it off.

I don't have anything readily handy. The contractors told me that they will have to run new supply and return handlers and not touch the vents upstairs.

Both of the current units are made by York.

First floor model number is: G1UA030514B

Second floor model number is: G1UA036514B


We have city water heated by a gas (natural) powered unit. I read the following off the unit:

Bradford White

Model: MI75S6BN12

Capacity: 75 gallons

76000 BTU


Thanks Bill.

From what you have said so far I would go with a zoned system. If you could provide a layout of the basement it would be helpful. The price does seem steep but without a drawing or specs of what you will be receiving it is hard to judge value. Ideally you need a drawing and spec. sheet that all contractors need to bid from.

Bill,


I have attached a rough draft of the basement layout. This is a bit old and the dimensions are a bit off. This was just something I was working up in the planning stages but you should get a decent idea of the space I am working with.


Thanks again for the help,

T.Wells

Wow, nice large basement. could you identify the four ducts please.
Forget the theater...show pictures of your train room. :)

Thanks.


From top to bottom (4 total)


1. 1st Floor Return

2. 1st Floor Supply

3. 2nd Floor Return

4. 2nd Floor Supply


Sorry for the delayed response. We have a newborn :D that is taking up some of my time (well alot).


Thanks,

T.Wells


Update: I asked both contractors to move the ducts to the sides to create more headroom and a tray ceiling however, this really is not feasible.

Dennis,


I would be happy to share a few pictures of the room which will be re-located to this new space.


It is my father-in-law's train room. His area is about 3x what I have allowed for here. I had to negotiate for my HT room space. He is doing my construction and would have wanted the entire basement to be a dedicated train room. He actually gave me a couple of extra feet in the HT so the room is ~25' long. My wife is an only child and he wants to set-up his trains at our place eventually so we can enjoy them for many more years. He only runs Lionel O gauge. His current set-up runs a number of engines (in the teens). I would be happy to share a picture if you are interested (do you design train rooms as well?).


Can I possibly pick your brain on my current situation?


Thanks,

T.Wells

What is the problem? I would definately be relocating those ducts to the perimeter. they are going to cause head room problems for the rear row and the projector.


How cold does it get in the dead of winter where you are? I have been doing HVAC for 20 years and I have never seen a heat pump run in the A/C mode in the dead of winter, how will the contractor maintain the head (high) pressure side of the system. What will be the lowest outdoor temperature they will guarantee that your A/C will run at without freezing up the indoor coil.


I would suggest that you go with the zoning system. Make sure that the new main ductwork Supply and return are acoustically lined . (You don't want to be hearing Gomez Addams crashing his trains next door) :D You will need a condenser fan cycling control added to the outdoor A/C unit, this allows it to run down to 0 F. You might also need a larger compressor crankcase heater for cold weather starting and possibly a time delay to bypass the low pressure cut out switch if it has one. Make sure the main zone controller has a supply air temperature sensor that will shut down the heat or A/C if the temperatures get too hot or cold. Try to locate the bypass damper duct where it dumps into the return as far away as possible from the furnace. Don't forget to oversize the supply and return registers and to put in dedicated return ducts from your theater.

I think one of the trains ought to run through the theater via the light trays in the soffit.
