Yes a higher SEER can help reduce electric costs. However. In most cases this will require changing both the indoor and outdoor units. In other words if you have a 10 SEER matched system and only upgrade the outdoor unit to a 14 SEER you will not get exactly 14 SEER efficiency. They must match.

Before excepting bids on new equipment I would first higher a licensed company to measure the Heat gain/loss from you house. This information will tell you if the current system was originally sized correctly. The improper sizing can lead to high electric bills as well. I hope this helps.

How do I read my new meter that is hooked up to my solar panels?

Interesting question. We have solar too but never got around to learning how to read the meter itself as I usually look at the on line (phone app) for the solar production. Reading the meter can give you the actual amount you will be charged if you have the 1st of the month reading and the end of the month reading. With a bit of math you can subtract the amount your panels produced to the amount you used. That's the basics used on your electric bill. Though they do add in the tax, fuel fee, and Admin charge. The fees are usually only charge if you used power in excess of what you produced. But they will always charge the Admin service fee which is about $18 in Hawaii. I've heard similar (under $20) charges in other states.
"888888" is a test mode to check display
"001 ######" Lifetime consumption (power used)
"071 ######" Lifetime over production(power sent back)
"252" The type of service (which is NETMETERING)

* Yes, a bit confusing and requires you to gather up your old electric bills to get all the numbers. I generally look on the bill for the daily K-watt usage and compare that to the daily usage. We use 42 Kilo watts per day in our home. If the solar produces 42 K watts today then I have an idea that we produced enough to cover today's power usage. Rainy days will produce less be may be compensated by several sunny days. The summer is always best as the sun shines all the time. No worries. Usually the first year after a new solar installation. The customer will incur some months with a higher bill (but still lower than a non-solar billing). But as the year progresses into the summer (or sunny months) your bills will lower usually to the Admin charge level. It will be higher if you have an under power demand system (or under sized system, BELOW what your normal usage is.)
Next year you will probably forget about checking and reading as the bill will settle.

Mismatched heat pump

well..this is a load variant issue. Depending on your cooling load, and the voltage input fluctuations(energy in does not equal energy out) you will have the air conditioning equivalent of a mismatched differential in a Jaguar.

If you can limit the coolant temperature range, via the thermostatic control, and keep a close watch on your fluid pressure/levels, you might get away with this.

usually, you want to have this arrangement in a reverse differential.

Air Conditioner SEER Seasonal Energy Efficiency Ratio

Energy consumption for home air conditioning accounts for almost 5% of all the electricity produced in the USA. Energy Policy Act mandates minimum energy efficiency standards for commercial buildings, using research and standards developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. Energy Star qualified central air conditioners have a higher seasonal efficiency rating (SEER) than standard models, which makes them about 14% more efficient than standard models. Energy efficiency specialists with certified training on retrofits and energy savings on both residential and light commercial units may enable you to save up to 50 percent on your air conditioning bills with the use of a high efficiency energy system. Substantial energy savings can be obtained from more efficient systems.

SEER (Seasonal Energy Efficiency Ratio) is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics. SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations.

The SEER rating is the Btu of cooling output during a typical cooling-season divided by the total electric energy input in watt-hours during the same period. SEER is related to the Energy Efficiency Ratio (EER), which is the ratio of output cooling in Btu/Hr and the input power in watts W at a given operating point and also to the coefficient of performance (COP) commonly used in thermodynamics. SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations. The higher the SEER number, the greater the efficiency of your unit. Therefore you will realize greater energy savings. The higher efficiency your product, the lower your long-term energy costs will be. Both central AC and air source heat pumps are rated according to seasonal energy efficiency ratio (SEER).

Before you consider upgrading your cooling equipment, the cheapest way to save money and energy from cooling is to reduce the need for mechanical air conditioning in the first place. Ask your contractor about a variable speed air handler, which will improve comfort and efficiency and allow continuous air filtering at minimum energy cost. Also, because ducts are often responsible for a lot of wasted energy, make sure you hire a contractor who knows about high-efficiency installations. If your central air conditioning unit is more than 12 years old, replacing it with an Energy Star qualified model could cut your cooling costs by 30 percent.

Unfortunately the quieter ones are more expensive. I have a variable speed Trane '19 seer' which is extremely quiet. But, with the higher 'seer' I save money on electric.

I live in Phoenix, AZ. I have a 2 story 2300 sq ft home built in 2001. I have two Carrier AC units outside on the side of the house. They are the originals. The Large unit (upstairs) model 38CKC042340 and...

T the upstairs is a 3 1/2 ton 10.0 SEER condenser, and the downstairs is a 2 1/2 ton 10.0 SEER condenser. You can use any 10 SEER Unit on replacement, but if you go any higher in SEER (efficiency), there is a possibility the unit will freeze up. The reason is because the indoor coil also has an efficiency rating (10.0 SEER). It is not a good idea to mismatch units when it comes to SEER. Otherwise, you can use any brand of unit, if you want to go higher in efficiency, you need to change the indoor coil as well. Hope this helps. Mark

I had Ruud heating and cooling installed five years ago. Last summer my electric bill doubled when I began running my air conditioner. It did not do that the first few years that we were in this house. ...

Hello In a way you are stuck with what is called a S.E.E.R. rating which is a statement of efficiency from the manufacturer.Ex: a 10seer is less electricity to run than a 14 seer.The model # would have told me the seer rating.A 4 ton `1 zone is a large unit but even a 10 seer 4 ton is never cost prohibitive to operate and Never doubles the electric bill in 5 days out of thirty.Is the home unoccupied all month and you use it on weekends?Did the neighbor run a strange wire to your property?There might be stray or lost voltage in rare cases if there is poor grounding issues.Has the unit been serviced? A low freon charge will cause a unit to run excessively long and not cool.Do you run the indoor blower all the time.Has there been any other major purchases made (at all) that you plug in?I would look at everything because there is some cause for DOUBLE bill amount not just the cooling bill.Good luck

I have a RUDD UPNE-042JAZ. How many tons is that?

That is a 3.5 ton heat pump at 13 SEER.
A S.E.E.R. (Seasonal Energy Efficiency Rating) is the rating and performance standards that have been developed by the U.S. government and equipment manufacturer's to produce an energy consumption rating that is easy to understand by consumers. It has a universal formula and conditioning that can be applied to all units and compensates for varying weather conditions.

Basically, the lower the S.E.E.R. rating, the more energy (electricity) is required to produce the desired effect.

High mileage car. Low quality Kenyan fuel. Low on

High on mileage means that the engine has done a lot of work, possible that the compression is down, need to check if this is below level, if there is oil used in excess then the engine needs an overhauling subject to the cost estimated.

Cant compromise on bad fuel as this will bring down the power of the engine.
High fule consumption means poor setting so fuel and ignition , check fuel settings- pump calibration and timing.

How old is this unit? Will newer units be easier on electrical consumption?

Unfortunately, the model or serial number doesn't show in your question. I see this all the time, I guess it doesn't show all of your information sometimes. So for your first question, you will need the serial number if you don't have a manufacturing date on your data plate somewhere on the unit. In the serial number, it's usually the first 3-4 digits after the letters. Example C1085???. These digits in order will give you the month it was made and the year it was made, so in my example it would be made in October, 1985. It's really hard to tell without a serial number posted though. For your second question, any unit made before 1992 will have around a 10 seer rating or less and some there after. In the most recent few years, you won't get anything less than a 13 seer unit, which is about 30% savings in cost to run the unit and a lot less energy consumption. You can now get up in the 20's with seer ratings which save a ton of money but cost a lot too! Hope this helps and if you still can't figure out the year for your older unit, try posting the serial number in the question itself. Good luck!

I have a 10 SEER heat pump about 16 years old, yesterday I notice that the outside unit was making a loud click noise in the heating mode. It's very close to the defrost electrical curcuit board. The unit...

Depending on make and model sounds like a check valve clicking. It can sound like it is coming from that area. You say your unit is 16 years old. Honeywell did servey on unit 10 years and older and found out they loose 25% effeicency after 10 years. You may think about changing it out. With the new tax credits you can get a 16 seer unit for the price of a 13 seer. I went from a 10 to 15 seer and my power bill dropped 40%. Rus.
