Sounds like you need to raise the thermostat a few degrees. Could be a couple of different issues. It could be airflow has dropped from a clogged coil, bad fan motor, clogged fan blades or a combination of all three. It also could just be you're using the wrong filter. Are you using a pleated type "high efficiency" filter or one of those hog hair filters? You can try taking the filter out and see if that stops the freezing (make sure the coil is completely thawed though before you try this). If that solves your problem then go buy some of the el cheapo air filters which aren't restrictive but do allow more debris to get by them. It also could be low on refrigerant. It could also be a combination of all of the above. Without more information, which you're most likely not going to have access to, we can't help you any more than that.

you'll need to call a technician. Assuming this is a 10 SEER system or less the Approach for the evaporator coil should be 35� below indoor ambient. That means at 72�F the evaporator should be operating at around 37�F. The "approach method" is the expected difference in a properly operating HVAC system between condensing/evaporating saturation points and the indoor/outdoor ambient air temperature.ac unit in cars That should mean a higher heat load on the evaporator (unless there is an airflow problem) which wouldn't cause freezing issues.what is the best ac window unit For the record, the average residential system would hold less than four pounds, so that was pretty close to empty.buy house ac unit My first guess is a clogged air filter, this is the most common cause.

If you compare a new air filter with old one, you'll notice that the new one is white and the used one is off white in color. This is when you should replace it. you should never allow it to get so clogged that it's any darker than off white in color. If your filter is OK, my next guess is the coil is clogged with dirt caused by not replacing the filter often enough. 43,216 posts, read 43,024,441 times If your filter and coil are not blocked then Your low on freon. Before you ask here is why. The pressure in the suction line is kept at a level that keeps the evaporator from freezing. If your low on freon the pressure drops in the line bringing the temperature below freezing causing it to ice from the evaporator right back to the compressor. While the line runs colder you actually lost capacity from your system from the loss of refrigerant. Loose anymore and the iceing will stop and the air coming out will start to be warmMontgomery, ALCustomers of home warranty companies, such as American Home Shield can take heart that some previous home warranty lawsuits have resulted in settlements.

One American Home Shield lawsuit resulted in a settlement, although the company did not admit any wrongdoing or liability in the settlement.The settlement was the result of a class-action lawsuit filed by Laura and Steven Faught against American Home Shield on behalf of people in the US who purchased or were issued a home service contract from American Home Shield from July 24, 2001 through October 19, 2009. As part of the settlement, American Home Shield agreed to establish a review desk to consider claims from settlement class members whose claims were denied during the class period.

Furthermore, the lawsuit alleges, American Home Shield denies claims because of minimal uncleanness, even if outside factors were the cause of the appliance's breakdown. Plaintiffs allege contractors were given a bonus for denying legitimate claims. The lawsuit claims breach of contract and fraudulent misrepresentation. Plaintiffs seek damages in excess of $75,000.

What Is An Air Conditioning Dry Charge?Over the past several years, both the U.S. and Canadian governments have directed that all producers of air conditioning equipment phase out production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been standardly used in air conditioners and heat pumps for many decades. The recommended phase-out mandates are anticipated to have the HVAC industry move to a more earth friendly refrigerant with a technical label R410A. has been shown to be safer for the environment. In late 2010 most air conditioning manufacturers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. more commonly called “dry charged units”. can legally be sold and installed which permits your your city area HVAC

How expensive will R-22 get in the next few years? It is likely that as a result of supply and demand, the refrigerant will probably go up in price.
