There are other methods for researching air conditioning, heating and ventilation companies such as: contact your regional Better Business Bereau (BBB), perform online searches and reviews and ask the business in concern for references. Nevertheless, all of these techniques fall brief of thorough openness. The BBB in fact works for the business it represents as they are only rated if the business in concern pays them a repeating fee. Online evaluation sites rarely display all the reviews received, and post reviews from sources that are not constantly reputable. This offers a platform for companies to post their own reviews and individuals to hastily post evaluations without the company in question's capability to professionally solve the problem. Furthermore, no business would give out a negative reference; only those that are extremely positive. None of these are perfect dynamics for consumers looking for completely objective reviews and recommendations. It is encouraged to utilize these approaches as an informed consumer and consider the info source for what it is worth.

3rd party providers such as Angie's list, Find Regional and other online companies are the newest platforms for sourcing and ranking cooling, heating and ventilating companies. Although these companies do supply a service with some benefit, they are, in truth, adding cost to the consumer. Angie's List, as well as some other online service directories, charge the client straight for their rankings and companies' contact information. Other third-party sites supply customers with air conditioning, heating and ventilation companies and add the cost of being a middle-man to business formula. Keep in mind that none of these are "free" and that customers ought to understand the cost and worth of utilizing entities like these.
Multiple price quotes are suggest when working with a cooling and heating specialist. There are no industry standards for prices A/C associated service or products. Comparable jobs can vary countless dollars from one company to the next. A minimum of three price quotes is suggested prior to the repair work or replacement of any significant cooling and or heating unit element and before the design and installation of brand-new systems.
A second opinion can be of value if the repair or replacement is pricey. Not all technicians or companies are equivalent or trusted. Fixing a/c and heater is exceptionally intricate. It is not unusual for a repair technician to be unable to separate the issue or for an agent to advise an unneeded purchases. Getting in touch with a competing cooling and heating company can save money and time and regret.

How To Convert 1 Ton To 1 Kw?
How To Convert Ton To Kw
Unit of refrigeration
Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling. Commercial refrigerators in the US are mostly rated in tons of refrigeration, but elsewhere in kW. One ton of refrigeration capacity can freeze one short ton of water at 0 °C (32 °F) in 24 hours. Based on that:
Latent heat of ice (i.e., heat of fusion) = 333.55 kJ/kg ≈ 144 Btu/lb
One short ton = 2000 lb
Heat extracted = (2000)(144)/24 hr = 288000 Btu/24 hr = 12000 Btu/hr = 200 Btu/min
1 ton refrigeration = 200 Btu/min = 3.517 kJ/s = 3.517 kW
A much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (i.e., 1000 kg) of water at 0 °C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW. As can be seen, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration.
Most residential air conditioning units range in capacity from about 1 to 5 tons of refrigeration. So ballpark about 3.5 kw or 12000btu per hour
Why The Air Condition Take Ice In The Winter?
When The Ice Tends To Insulate The Coil From The Air Why The Heating Is Decrease And What Hapen Inside The Coiles And Compressor Please Gave More Information ?
Actually you are describing a heat-pump. It has two modes of operation, cooling and heating. The cycle is reversed during the cooling mode.
During the heating mode, the heat pump takes energy from the outside air and warms the coil inside the house.
The outside coil needs to be cooler than the outside air in order for the heat pump to work
During the winter the outside air can be below freezing, and the heat pump will continue to drive the coil temperature down to try and get heat from it. (most shut down and go to emergency heat around 38 degrees F)
If the air is 40 degrees the heat pump coil is likely 25-30 degrees and that is below freezing, the small amount of humidity in the air freezes to the coil and begins to block the heat transfer area and reduces the heating ability.
The heat pump should sense this problem and go into a defrost cycle to clear the ice.
If this doesn't happen there could be a problem with the unit.
I Want To Know How Many Tons An Air Condition Split Unit With 4.8Kw How Can We Change Kw To Tons Of Air?
How Can We Change Kw To Tons Of Air For Air Conditions
1 ton is 12000 btu/hr of heat removed, or 3.516 kw. So 4.8 kw would be about 1.36 tons of ac.
I Am Researching About Goe-Thermal Heating.?
Now I Understand The Basics Of Residential Heating & Cooling, So When You Compress A Refrigerant Such As R22, You Slow Down The Moulacules From Moving. Now That Will Lowere The Temp. Of The Refrigerant. But In Geo-Thermal Heating, When Heat Energy Is Extracted Form The Ground By The Way Of A Closed Loop System. It Is Then Put Under Pressure Via. A Compressor, How Does It Create Heat? Would You Not Be Doing The Same A Condensor/ Compressor Unit Of A Air Conditioning Unit? Thank'S In Advance For Any Answers!
A geothermal unit works off of the same principle as as conventional heat pump. The main difference is that the Geo unit is self contained inside the house and it uses a constant ground temperature of around 60 degrees to extract the heat from versus 0 degree or 45 degree outside air temperatures. In the summer you dissipate the heat back into the ground which is also easier than getting rid of it to 95 degree outdoor air temperature. The water and ground act as your condenser would on a conventional system but does it much more efficiently. You can also heat approximately 40% of your hot water with one of these. Check out www.geoexchange.com and that will answer alot of your questions. Good brands are Water Furnace and ClimateMaster.
What Are The Top 5 Ranking Air Conditioners?
Need Information For Highly Recommended Residential Air Conditions With Heat Pump.
American Standard (who also makes Trane brand)
That's where i'll stop.
At the bottom end, there are Nordyne that makes about a dozen contractor grade brand names, and Goodman who also makes about a dozen at the lower end of the scale.
Be sure to get a good contractor to install it for you, as installation is just as important as selecting a good units.
Also, larger is NOT better. To right-size the unit, the contractor will have to do what is called a "heat-load calculation" or other wise known as Mode-J calculations. Here, the contractor will measure your room size, orientation, widow size, size of the duct, etc, and arrive at the right size unit.
To small, it won't effectively cool or heat the rooms. To large, it will cycle so fast, it will never reach the long run time that is required to reach the maximum effeciency and de-humidification.
