There are other approaches for investigating air conditioning, heating and ventilation business such as: contact your local Better Business Bereau (BBB), carry out online searches and reviews and ask the business in question for referrals. However, all of these methods disappoint thorough transparency. The BBB really works for the companies it represents as they are only ranked if the business in concern pays them a recurring fee. Online evaluation websites seldom show all of the reviews received, and post reviews from sources that are not always trustworthy. This offers a platform for business to post their own evaluations and people to quickly post reviews without the business in concern's capability to professionally deal with the concern. Furthermore, no business would provide an unfavorable referral; only those that are extremely favorable. None of these are ideal characteristics for consumers looking for completely objective reviews and referrals. It is recommended to use these methods as an educated consumer and consider the information source for exactly what it deserves.
One of the very best ways to discover a brand-new a/c, heating and ventilation contractor is via the "word-of-mouth" method. If the business advised was affordable, expert and reputable for a buddy or family member, there is an excellent chance that company will do the same for you. Good companies utilize the word-of-mouth technique to continually offer a brand-new customer stream by keeping their clients happy.
Other traditional methods for finding a new air conditioning, heating and ventilation contractor include performing online searches, phone book directories or online directory sites and other advertisement mediums. Keep in mind that all of these techniques are bought and paid for by the companies in concern. None of these methods ought to serve as a testimonial and should be utilized only as finding sources.
3rd celebration service providers such as Angie's list, Discover Regional and other online companies are the most recent platforms for sourcing and score cooling, heating and ventilating business. Although these companies do provide a service with some merit, they are, in reality, including cost to the consumer. Angie's List, along with some other online business directory sites, charge the client directly for their scores and companies' contact details. Other third-party websites supply customers with cooling, heating and ventilation companies and include the cost of being a middle-man to business equation. Remember that none of these are "complimentary" and that consumers need to understand the expense and worth of using entities like these.
Several quotes are recommend when working with an a/c and heating specialist. There are no industry requirements for pricing A/C associated service or items. Similar jobs can vary countless dollars from one business to the next. A minimum of three quotes is recommended prior to the repair or replacement of any major air conditioning and or heater element and before the style and installation of new systems.
A 2nd opinion can be of worth if the repair or replacement is expensive. Not all service technicians or companies are equivalent or reliable. Repairing a/c and heater is very complicated. It is not unusual for a repair work professional to be unable to isolate the issue or for an agent to advise an unneeded purchases. Getting in touch with a competing air conditioning and heating business can save money and time and remorse.

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.
