Written Written Written Written Window Mounted AC units work on the principle of refrigeration to cool the air into your room. Any moisture in the air will condense on the coils and possibly turn to ice. Occasionally the AC unit will conduct a defrost cycle to break up that ice so that your AC unit can function normally.The unit should have a drain on the outside section to allow the water to drain out. If it is overflowing inside, you should check that the drain isn’t blocked.If the unit is blowing water droplets inside, this is could point to two things:It is particularly humid air that you are coolingThere may be a refrigerant leak. If this is the case, the best option is to replace the unit.Written It is normal for the dehumidifying process to create some condensation. However, if there are pools of what under you AC unit, there might be a problem. You may have a damaged condenser pump, improper installation, too much pressure within your unit, a clogged drain hole, or bad seals.Condenser Pump: To determine weather you have a broken pump, pour water into the condenser pan, and the pump should pump out excess water.

If it is not, the pump will need to be repair or replaced.Improper Installation: If your air conditioner was not installed properly, this can effect the unit. Make sure you check that the unit is leveled.Too Much Pressure: Closed or blocked vents create pressure within your air conditioner. This pressure causes the unit to leak water. Inspect the vents and make sure there is nothing blocking them.Clogged Drain Hole: The drain hole removes water from the unit. Debris can build up in the unit and therefore become clogged. Check the drain hole for any clogs and clear out any debris.Bad Seal: If you have loose, worn, or damaged seals in your unit, they must be replaced. If warm air makes its way into the unit and condensers with the cool air, a pool of water will form under the unit. Be sure to check the seals and replace them if damaged.You can find Room Air Conditioner Repair Help on our Website, along with original manufacturer replacement parts for your unit here:Room Air Conditioner Repair HelpRoom Air Conditioner Parts

Question: My air conditioner unit in my home runs just about constantly just to stay at 76 degrees. Do I need to add more freon? Or do I need to replace my AC unit before summer gets here? ac window unit is not coolingMy electricity bill was over $350 dollars last month in April!window ac unit not coolingAnswer 1 – It will depend on the temperature of inside your home and the outside air temperature and also how well your house is insulated. sizing ac units square footageIf you have vaulted ceilings and lots of big windows then this is something to consider. If there is cold air blowing from the vents then it may be doing all it can to keep it at 75 degrees. At times the AC Evaporator can get dirty from use. If this is dirty it will decrease the effectiveness of the AC unit temperature.

You can try cleaning the evaporator coil with this cleaner here.Answer 2 – Throw the expensive restrictive return “pollen” home air filters away and put a cheap free flowing return filter on there instead. Those high dollar filters are for equipment protection and are very restrictive. The allergy catching filters are total gimmicks and are too restrictive for the normal A/C system. Or you can swap out your return grill to a huge size to make up for reduced airflow through the restrictive filters. Getting the cheap blue or green 99 cent filter is the cheapest way to improve your AC to not constantly run and to improve it’s effectiveness.How often to change air filter for your AC unit in SummerAnswer 3 – First of all… The word “freon” is a brand name for a refrigerant named R-22 (Refrigerant 22). Other types of air conditioning refrigerants are called R-134a, R-404A, R-407C, R-12 and R-410A. Also the actual refrigerant that is named Freon was banned years ago. To be able to work with R-22 yourself you need to be certified by the EPA.

(If you want to know more about refrigerant info requirements from the EPA click here) Anyway, your unit is probably undercharged (not enough refrigerant) or overcharged (too much refrigerant). Usually an AC mechanic or tech company will come out and check the refrigerant with industrial gauges for about $30 dollars. Have them come out and check your A/C before you buy a new unit of course!Answer 4 – A bigger air conditioner unit is not always better when it comes to HVAC equipment. The unit must be properly sized for the house it is going to be used on. There are many factors that go into a load calculation. Consider things like the number of windows in your home, the east and west sunshine exposure, and your homes insulation. If you do not get cold air out of the AC vents then you could have a refrigerant issue. Most people cannot check this themselves so it is best if you call an Air Conditioning Technician. Have them come out and check your refrigerant to see if it needs to be filled.

If you are a Groupon member there are usually great discounts on getting your AC checked to see if repairs are needed. You can also check your AC air filter to see if it is dirty and clogged. A dirty AC air filter prevents air flow from going across your indoor evaporator coil. Remember to change your air filters every 30 days in the summer months.Home A/C Air Conditioner DiagramAnswer 5 – If you have approx 17 degrees difference between the supply air (air going into the vent) and the cold air coming out of the vents then there is nothing wrong with the unit itself. It just means it is so hot outside that your unit cannot keep the temperature up. Check to make sure there are no windows open and that any sliding glass patio doors are not cracked open. Another thing to check is to make sure the sliding glass doors and windows in your house have a proper seal. Some seals on doors and windows will rip or come loose over time thus letting precious cold air escape outside.Answer 6 – Set the thermostat a few degrees higher (from 76 degrees to lets say 79 degrees), you will save energy and money.
