How do you find out the efficiency of your HVAC unit?
Find the name of the manufacturer, model, and serial number of your unit. I recommend contacting a local HVAC company with this information. They will be able to contact the manufacturer to find out the efficiency. You can even call the manufacturer directly and they may be able to get you the information you seek.

Answer: Electric strip heat has virtually no maintainance, but is the mostcost inefficient source of heat there is. The heatpump will saveyou some $ on operation but is usually supplemented with anelectric strip that operates while the HP is in defrost modeanyway. Also the HP is a mechanical device… which can be prone tobreakdown and maintainance costs and because they run year roundthe life span is roughly 1/2 that of a central a/c unit. Lastly,heatpumps are only a viable choice in mild climates as they use theambient heat outdoors to heat the home. So if the temps in yourarea are often (MORE)
Why does the fan on an HVAC unit kick on intermitently when the unit is turned off at the thermostat?
Answer: . With the thermostat in the off position, the answer would most likely be the fan control or fan switch. This would most likely occur during the summer when temperatures are higher. The function of the control in normal operation is to keep the fan going to extract the balance of the hea…t from the heat exchanger after the burner cycles off in a call for heat. If it is a Honeywell adjustable, you can hold the dial in place and adjust the pointer that is set to the "lower" temperature of the two pointers. You would increase the setpoint of the pointer a bit. If it is not adjustable, replacing the control would be the answer if you can't live with it. Answer. It continues to run after shut off for a minute or so to clean the lines of heat/cool air. It also runs intermittantly to recirculate air to filter dust out and even out the temperature.. This will also happen in the winter if you have frost protection. External frost protection set point 0-5c internal set point can vary but normally about 8-12c. (MORE)
Answer . I am a HVAC man from South Carolina...A heat pump uses outsid ambient Air tepms to run efficently...It some times get to cold here in myrtle beach for a heat pump...Any outdoor ambient air temps below about 28 degrees a very bad thing. The first of many reasons...Outdoor coil would neve…r defrost. The number 2 reason the outdoor fan motor would freeze....from slush turning to ice cicles...the Electric heat bill would be HUGE...I would say that you should use a straight air cond/ gas pack...gas is more than oil but WAY safer...or look into radient heat celings or floors..Ask a pro...Good Luck..Donald J Nesmith (MORE)
An insurance broker or agent licensed in your state can help youfind liability insurance for your HVAC Company.
Answer . Basically, you need to calculate the amount of energy contained in the fuel you use to produce a given amount of electrical energy. To calculate the amount of energy in the fuel you need to lookup the number of thermal energy units per unit volume then you can convert those thermal ener…gy units into Joules (1 gallon [U.S.] of diesel oil = 146 520 000 joules - www.onlineconversion.com) The on the electrical side, just multiply the voltage by the current by the number of seconds of run time (unvarying load) to get the electrical power output in Joules. Then the efficiency is just the the output power divided by the input power (x100 for %). (MORE)
The question is too vague, It depends on the Tonnage (BTU's) and or the Horsepower of the fan motor.
there is no such thing as an efficient toaster so there can't be a lower efficient toaster.
Your unit is freezing up out side like a block of ice? if so then obviously you have a heat pump.. what is happenong is your defrost board or thermostat on the out side unit is no good and needs to be replaced.. if you cant afford service on it, to defrost the unit some what quickly, turn your air c…onditioner on for abour 5 minutes.. that should defrost the unit..

Many secondary and postsecondary technical and trade schools, junior and community colleges, and the U.S. Armed Forces offer 6-month to 2-year programs in heating, air-conditioning, and refrigeration. After completing these programs, new technicians generally need between an additional 6 months and …2 years of field experience before they are considered proficient.. Many technicians train through apprenticeships. Apprenticeship programs frequently are run by joint committees representing local chapters of the Air-Conditioning Contractors of America, the Mechanical Contractors Association of America, Plumbing-Heating-Cooling Contractors-National Association, and locals of the sheet metal workers' International Association or the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada. Local chapters of the Associated Builders and Contractors and the National Association of Home Builders sponsor other apprenticeship programs. Formal apprenticeship programs normally last 3 to 5 years and combine paid on-the-job training with classroom instruction. . Applicants for apprenticeships must have a high school diploma or equivalent. Math and reading skills are essential. After completing an apprenticeship program, technicians are considered skilled trades workers and capable of working alone. These programs are also a pathway to certification and, in some cases, college credits. (MORE)
Many variables including size, efficiency, brand, and so on. As a general answer 3-10000 usaully 3 for a smaller system and 10 for a large high efficiency unit with options.
there is no unit. its usually a percent. so it would be something like joules/joules, which would be nothing.
There are a lot but some of them are. Fan . Coils . hot water piping . chilled water or refrigerant piping . Pumps . Distribution system(ductwork)
By finding the centermost point. Then with trial and error you can balance it. Could get heavy so you might need to workout some before. Maybe start with plates then tables before attempting an HVAC system
There are a few things that could cause this, your thermostat could be bad, you could have crossed and touching wires on the low voltage side, also your fan relay could be sticking all of which would require a technician.
There is NO typical home central hvac unit. Like fingerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do to. Between those two intangibles you can vary from about 2 to 8 Lbs. of "freon".. There is NO typical home central hvac unit. Like fi…ngerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do too. This creates two intangibles that cause the refrigerant level to differ quite a bit. Smallish units with a high efficiency rating can be as low as 2 lbs. A large 5 TON system can take as much as 8 lbs.. Hire and trust a good HVAC mechanic. (MORE)
It means that it does not have an air conditioner or furnace installed. HVAC stands for "heating, ventilating, and cooling". HVAC is an integrated system that is not free standing, like a window air conditioner or heater.
Efficiency is normally written as a percentage, and does not have an SI unit. "percent". It has no units.
HVAC unit is basically combination of HVAC chiller and all related equipment. See below related link for all details
HVAC is the heating ventilation and air conditioning system that provide man and animal to comfort air
Drop it in, connect the ductwork and wiring that`s it. No field piping, leak checking,evacuation or charging.
The average life-span of a whole house HVAC unit is 10-14 years. The cost to replace your current unit will depend on several factors: How was your home built? Does it have adequate insulation? What type of climate do you live in? Homes in the northern half of the country typically need more he…ating capacity while homes in the southern half will require more air conditioning capacity. What is the size of your home? Do you have more exterior walls facing South and West or North and East? Do you have large windows? Because a central heating and air conditioning system is not an off-the-shelf product, it requires a professional dealer to assess and install a system that's right for your home.

Somewhere on it, it will have a specification plate - that will include power and/or current drain. If it has only power, divide that by the supply voltage to get current. Otherwise, the weight of the thing is no clue as to power drain.
Divide the btu output rating by the btu input rating. Both of these values can be found on the furnace`s nametag.
Efficiency is the ratio of output to input in a system. Since this invloves dividing one dimensional number by another with the same dimensions, the result is dimensionless. i.e. it has no units. The ratio is generally expressed as a percentage, as in "The generator has an efficiency of 33%", which …indicates the output is approximately one third of the input. (MORE)
\n. \n. Because efficiency is measured in a ratio. \n. Energy out of the machine divided by energy going into the machine equals efficiency. \n. You can get it as a percentage, but that's about it.
you have to do: work (output) divided by work (input) = F x d (output) divided by F x d (input)
Answer for USA, Canada and countries running a 60 Hertz supply service. The unit will stop operating as it needs 240 volts for the fan to operate. If it is the leg that is used for the control portion of the system, you will get no indication of power at all.
If you suspect a problem you`re probably right. Call someone before you find yourself in a real mess. Nobody here can really help you.
Will homeowners insurance cover the installation of a HVAC Unit if your house never has had one before?
NO, Your homeowners Hazard Insurance Policy does not pay for maintenance or other home upgrades. However upgrades should be reported to your insurer as they can be covered if damaged or loss occurs from covered peril on your policy. If your Insurer is not aware that you have added an HVAC unit it wi…ll likely not be covered if damaged. (MORE)
There are a few ways to go about factoring. You can decide whatworks best for you. I always find the prime factorization first.Let's look at a random number: 108 The prime factorization can be found by using a factor tree. 108 54,2 27,2,2 9,3,2,2 3,3,3,2,2 2^2 x 3^3 = 108 Half of the factors will b…e less than the square root, halfgreater. If the number is a perfect square, there will be an equalnumber of factors on either side of the square root. In this case,the square root is between 10 and 11. Adding one to the exponents of the prime factorization andmultiplying them will tell you how many factors there are. In thiscase, the exponents are 2 and 3. Add one to each. 3 x 4 = 12 108 has 12 factors. Six of them are 10 or less, six of them are 11or greater. All we have to do is divide the numbers one through teninto 108. If the result (quotient) turns out to be an integer,you've found a factor pair. Knowing the rules of divisibility willmake that even easier. 108 is divisible by... 1 because everything is. 2 because it's even. 3 because its digits add up to a multiple of 3. 4 because its last two digits are a multiple of 4. 6 because it's a multiple of 2 and 3. 9 because its digits add up to a multiple of 9. That's six factors less than 10. Divide them into 108. That's therest of them. (108,1)(54,2)(36,3)(27,4)(18,6)(12,9) 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108 Notice that all of those numbers, except for 1, can also be foundin the prime factorization. (MORE)
