The best thing you can do to help efficiency on an existing unit is to keep the condenser coil clean and its air flow unobstructed. Same for inside, keep a clean filter and make sure the air flow is not obstructed, nothing in front of the return air grill.

Why are my equipment rating numbers important.


Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your heating and cooling bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).

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.

I have an Emerson Refrigerator Model No: CR286BSE and it out of nowhere it stopped working and know it is making a clicking noise and will not cool anything at all but the compressor gets hot.


Your compressor is shot, I would recommend not letting it run, it could over heat and develop a leak, the refrigerant is extremely toxic, and if it ignites creates Phosgene gas which is incredibly dangerous. IF, you can find a compressor for the model it may be worth it to replace it, or buy a new one. Good Luck!

Is 32c a normal temp for an exhaust on a force air high efficiency house furnace? This is the air temp that goes outside after heating the plenum. Is there a lot of heat going up the "chimney"??


Any furnace providing heat where it should and has little to no heat from its exhaust is doing a GREAT job ;-)

Our high efficiency gas furnace was installed with a PVC pipe as a 'chimney' which bothered me to no end until I found the surface temp of that plastic pipe only barely warm to the touch- that is a home run!

Becoming more efficient with your heating and cooling


Here are some ways to become more efficient with your heating and cooling. Obviously you do not have to do them in order but try to complete as many as you can! = )
· Buy a laser thermometer! You can use this to detect air leaks (or at least areas with “minor” temperature differences) so you know where to put seals
· Keep blinds shut on hot days and open on cold days----helps reduce temperature extremities
· If the temperature is can be negated by using a t-shirt or a jacket, use that clothing! You will save temperature control costs and still be able to keep warm or cool
· Do not use those old lightbulbs on hot days---they make extra heat increasing cooling bills (but you can use them on cold days to help warm your house)
· Utilize energy star products to increase efficiency comfortably
· Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer.
· If you are on vacation, turn of that air conditioning/heating! No one will be in the house if everyone is away and it shouldn’t be too uncomfortable to wait like one hour for the house to cool/heat
· Don’t turn your thermostat up/down just to heat/cool faster---all temperature control changes the house temp at the same rate and if you forget to turn it off, you just wasted some energy there!
· Don’t block heating/cooling vents so that your rooms can be controlled quickly and so that your air actually gets controlled, not your furniture
· Check up your air conditioning and heating systems regularly (not once a month but maybe once every year) so that the systems stay running the best they can

Just had a new house built and its all electric. Has a Tempstar heat pump. There are two model numbers involved: FSM4X4800A1 (attic unit) and N4H348AKE100 (outside unit). This is a 4 ton unit and I...


It's entry level with regard to efficiency. At the same time, it's not a bad piece of equipment. Made by Carrier ICP. I've installed many of these. I suspect since you had your house foamed, it's probably not costing you a heck of alot to heat or cool- so it would be hard to justify changing it just to add seer points. It would be difficult to get a pay-back on your investment. I say roll with it and enjoy your new home!

I have an '06 model combination cooling and heatin


For every 500 sq. ft. house or a 1-bedroom size new house you need 1-ton of cool . An old house you need a ton worth of cooling for every 400 sq. ft. house or a 1-ton per 1 bedroom size house.

I have the Renewaire Energy Recovery ventilator system, Model EV130, installed in my house but do not know how to set it to the proper setting. The runtime numbers go from 10 to 100 and I am not sure what...


The RenewAire system is sized per ASHRAE 62-1999, residential air exchange of .35 air changes per hour, or 8 air changes per day. You can find an operation sheet for the PTL @ www.renewaire.com, downloads, residential, controls, PTL. A chart shows a starting point of ventilation based on the square footage x 8 foot ceiling height with a run time percentage for each model. For 2250 square feet with 8 foot ceilings, the run time for an EV130 is 85%, cycling hourly.

Actual run time will vary by tightness of house, number of occupants, lifestyle (number and frequency of pollutant generating activities). Outside weather conditions should have little effect on run time percentage. I run my system @ 50% year round, when the windows are shut.

The ERV tempers humidity and temperature extremes of the ventilation air year round. It is not a substitute for heating or A/C; it does not dehumidify the house in summer (it does reject some of the incoming summer humidity content, when the net humidity is greater outside than inside). It will lower humidity of the house in winter, or whenever the net humidity outside is lower than inside.

It will ventilate the house in an energy efficient manner all year long. Based on this information, choose a setting and manage the amount of run time to achieve your best IAQ.
