Question about Heating & Cooling

1 Answer

I recently bought a 4 ton 14.5 SEER Rudd Spilt system using R-410 and matching Rudd furnace. This system replaced a Lennox 10 SEER 4 ton unit. Now that it has gotten hot in Baton Rouge LA 90-93 degrees. I have a programmable thermostat see bottom. It takes the one hour to drop the temp. 1 degree so starting at 5:00pm the unit runs non stop until 11:30 at night. The Lennox was about 3 times better and it was 15 years old. The installer told me all high SEER units take longer to cool in comparison to older units of same size. My utility meter for the first 8 days this month shows that I have already used 1,350 Kilowatts or about $350 per month. My highest bill ever was $300 in August last year. Is this normal? Is the unit to small? Thermostat settings 8:00am - 76, 5:00pm - 74, 9:00pm - 73 House built 1996 9 & 10 ceilings, double pane windows and R-25 insulation in attic,

Sounds like the Unit might be low on charge.But without correct readings not sure.
The new unit with 410 will actually cool better due to higher boiling point temp. of freon type.Poor air circulation could also cause problem.Such as dirty filter, too slow fan speed,dirty coil.Also could have obstruction in freon lines either at pump,in line set,or in coil.
Get someone u trust to check it out and ask for their Rudd Dealership Training Credentials.

Purchased Rheem 4 ton 16 seer AC installer just left


Ask your installing company for the AHRI number. If installed with a
matching furnace and coil as listed in the certification then you will get 16 seer rating. If they installed something different than what is listed in the certificate then demand all parts listed or a refund.

Goodman SSZ140481AG, what is it? is it 14 seer or 15 seer? I paid for 15seer but the unit has a decal on it reading 14 seer??? Thanks


It is federal law that each new piece of A/C equipment have the yellow SEER rating.
The higher the SEER, the less electricity the system uses to operate.
You need to follow up since it appears your contractor installed a less efficient/expensive system than what you paid for.
Good luck.

I'm looking to purchase a Rudd 2 stage model, 16 SEER, 5 ton along with a 100000 BTU 95% furnace. I have a two story home and will only be using the 1 AC. Will the Rudd cool both floors?


Assuming that there are ducts ran upstairs and downstairs, it all depends on the square footage of the living spaces, i.e. bedrooms, living room, dining room, etc. You need an average of 1 cfm per sq ft. For every 1 ton of air, you have an average of 400cfms. So your 5 ton unit will cool/heat 2000 sq ft. A 16 seer unit with a 95% furnace is a nice buy and you will notice the difference for sure. Hope this helps!

Going to replace hvac system. Don't know what


Hello,
According to the model number it is a 2 ton or 24,000 BTU unit. It is very important that you change the indoor coil as well as the outdoor section, due to it being a 10 SEER unit, and the new basic systems are 13 SEER, the old coil cannot handle the higher SEER ratings.
Rheem and Ruud are the same equipment, just 1 number different on the model number.
I hope this has helped, please rate the new guy :)
Please contact me if I can be of any further help to you.
Have a great day!
Sincerely,
Paul Gibson

After purchasing aGoodman 3 ton l3 seer R-410 AC,


not unless you already had a top of the line furnace. Ask your installer - you'll need papers and info from him anyway.

I need help selecting the best Amana 5 ton furnace/ac.


I believe you are asking which furnace to go with?

Just some clarification first.

The "condensor" is the outdoor unit.
A "Compressor" is the device inside the outdoor unit that pumps and "compresses" the refridgerant.

An evaporator is the indoor coil, it has refridgerant running through it.

The furnace is completely seperat from the condensor and evaporator.

I "THINK" you are saying that you are looking to buy an AMANA system with a 5 ton 14 to 16 SEER condensor, and a furnace, but you need suggestions on the furnace.

typically when you purchace a condensor, the evaporator coil is simply matched by the manufacturer to the specific condensor you purchace, there is no choosing to deal with. All condensors ofcourse come with a compressor already installed.

If my assumption about your request is correct, maybe this will help.

Amana's 90+ furnaces are great units. I would recomend them to anyone. The 80+ uses a somewhat inferior heat exchanger, and is ofcourse less efficient.
Anything higher than a 90+ can take quite a while to recoup the costs of the enitial purchace through your efficiency savings.

If it were my home, I would go with the 90+ furnace, and the 16 SEER Condensor/evaporator system. But ultimatly, its up to you, your efficiency standards and your wallets potential.

If you live in a northern state where AC is little needed, I'd go with the 14 SEER AC.
Again, an initial cost verses long term savings issue.
