Control climbs on its own. fan slowing down a bit

This unit sounded great. Its big and its somewhat energy efficient, and it runs on 110 outlet without issue.. Only thing is that Mine like many others seems to suffer from an intermittent problem where the temp control starts to climb up and beep on its own every few uses.. Can someone tell me if this is self serviceable or a warranty issue? The other issue is the blower fan seems to be running a bit slower then when new and I'm wondering if these too can be replaced or repaired without a huge issue. I have done some in the past where the bearings are not easy to get out of the tin housing.

Re: Control climbs on its own. fan slowing down a bit

If the air flow has decreased since new perhaps the air filter has not been cleaned. This may also solve your problem of the temp climb

Why tempstar 5000 High Efficiency a/c outside fan won't turn off ?

Sounds like your contactor is sticking in your outside unit. They could be welded shut.

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.

There is a huge heat swing in a poorly insulated dwelling on cold days running on 5 cycles. running more cycles causes a relay trip on new honey well 8184 4009 control?

Your description, actually provided the solution ... "a poorly insulated dwelling". The unit has to run more than what is considered the norm and it's over heating causing the relay to trip. Especially, if it's having to use the Emergency Heat (that happens when temps get below 32 degrees). It's a backup system for when the Heat Pump can't get any heat out of the outside air. The Emergency Heat is either strip heaters (similar to a kitchen toaster) or an electric furnace, neither of which is very energy efficient and having to run as much as you say, is causing the circuits to overheat and trip the relay.

The bottom line is this, improve the energy efficiency of the dwelling and the heat pump will become more energy efficient and you heating and air conditioning bills will significantly decrease.

Many have sepaarate speeds for heating and cooling....check it out there should be a heat relay and a cool relay and the motor taps are hooked to each so maybe you can just do a bit of switching wires.....

But, really you probably will have plenty of air flow for the cooling side also if your running that low of a differential on the heating side...
Try it out the worst that can happen is that you will freeze up on the cooling and then you can just switch it back...

I have baseboard electric heat. My units are 27 years old. I'd like to replace with more efficient units but can't find any comparitive data.

Hummm, well, the newer units are trying to meet or exceed energy standards, so good on you for updating. You can look at Consumer Reports data to see which is best, but this method of heat does not lend itself to the same refinements as a gas furnace, for example.
I prefer units that have oil, or fans. The oil filled gives heat without having the heating element energized.
The fan units heat the room much better, but this is often NOT an option on baseboards, as many are wall cavity types.
220 volt costs less to run than 110 volt models, but this also is not something easily changed at this stage....

Bryant High Efficiency Unit, runs constantly, I suspect the thermostat. Fan control and thermostat were replaced. The installer was to familiar with the installation. Could you please give me an idea of...

Any unit over 20 years is no longer energy efficient & it is past the lifespan of an AC. Get quotes from 3 different companies & go with best price with best warranty. I'm not partial to any particular manufacturer. They all get their parts from overseas.

Goodman a/c blower runs on auto and humidity problems

Is the air cold inside? You are talking about the fan inside? Have system check for freon but more than likely, it sounds like a t'stat problem. And it's not normal for the fan to run constantly.

Error code of 6 flashing light on circuit board,

There appears to be a short in the unit. Not sure where. The power to the fan is not interrupted completly when the fan shuts down, still feeding voltage to the fan, keeping it running slow. Before checking the wiring, please turn off power first.
