Tip & How-To about Heating & Cooling
With the heat of the summer many air conditioner are working hard and running up electric bills. Many old air conditioner would have dirty evaporator which blocks some or most of the air going through it. This make the system run harder since it cannot cool the house as it should. This causes the AC system to run continously without ever shutting off.
There is a new product on the market avaible at most AC supply store to clean the evaporator coils that do not need rinsing. It desolves mildew and other things that causes blockage. Make sure also that you change your filter regularly.
If your airconditioner has been on for a long time and does not shut off, you are wasting power. Turn the thermostat up just enough so it will turn off. Setting the AC lower will not make a diffrence in the temp when the wheather is hot since the system is not able to reach the desired setting because that is as cold as it is capable of. One degree of in setting can mean a lot over a whole month period. The rule of thumb is keep it above 75.

Since the failure of an air conditioner to turn on, loss of air conditioner cooling capacity, reduced air conditioning output temperatures, loss of cool air supply, or even loss of air flow entirely can be due to a variety of problems with one or more components of an air conditioner or air conditioning system, after reviewing the lost air conditioner cooling diagnosis procedures described in this article, be sure to also review the diagnostic procedures at each of the individual air conditioning diagnosis and repair major topics listed just below. To return to our air conditioning and refrigeration home page go to AIR CONDITIONING & HEAT PUMP SYSTEMS.
Electrical problems on HVAC systems: Keep in mind that despite the depth of technical detail you will find here about all components of air conditioners and heat pumps, most service calls for non-working air conditioners or heat pumps turn up an electrical problem. So if your A/C system is just not working at all be sure to check all of our electrical and control setting suggestions first.
Mechanical problems on HVAC systems: tend to fall into these groups: refrigerant leaks, dirty condenser coil or unit, dirty evaporator or cooling coil, or burned out (or hard-starting) compressor motors. We have also seen a number of problems with fans and fan motors in both the compressor/condenser unit and in the air handler/blower fan unit. Some of those fan problems are mechanical - like a loose fan belt or blade. MORE DETAILS
