Why is it important for an air conditioner to dehumidify?
Air conditioners keep you comfortable by removing heat and moisture from the air. To do both effectively, the unit must be properly sized for your space. If the capacity is too low, you may never feel quite cool enough. When the capacity is too high, the unit produces so much cold air so quickly that the room reaches the desired temperature before the unit has adequate run time to dehumidify. The result is a cool but clammy room that can feel just as uncomfortable as one that is not cool enough.
I occasionally see black particles blowing out of my unit. What are these and do I need to do anything about it?
If your unit is only a couple of years old, then what you are seeing is probably due to a maintenance issue. Air conditioners remove both heat and humidity from a room. That humidity condenses on the air conditioner coils and drains into the base pan where it is used to cool the unit. Occasionally, mold or mildew will take advantage of this high moisture environment. The only way to alleviate this situation is to have the unit professionally cleaned. Call Spot Cooling Systems to take advantage of our Maintenance and Service programs. The telephone number is 866-990-5700.
Why is there water in the base pan of my air conditioner?
Air conditioners remove both heat and humidity from a room. This process produces condensation which runs off into the base pan. This condensation is then used to cool the hot condenser coil which improves the unitâ€™s performance.
How do I determine the proper cooling capacity for my space?
See the sizing guide in any of our product specifications for specific information on choosing the right size unit for your space.
What model or product is best for my situation?
Depending on the type of installation and cooling capacity you need, you may find solutions that you never knew existed. Specific product pages explain each unit in detail so you can get a complete understanding of the features and benefits of every Spot Cooling Product product.
Spot Cooling Systems understands the factors that can affect cooling in your area, including average seasonal temperatures, building codes, etc., and can provide a wealth of information.
Whatâ€™s the difference between your premium and deluxe models?
All Spot Cooling Systems, products are manufactured to the highest standards. However, different customers and different installations need different solutions. Thatâ€™s why Spot Cooling offers so many choices. Our Air Cooled, Evaporative Cooled and Self Evaporative Units are commercial-grade and have great features that stand apart from any distributor or manufactures as an ultra-premium product with the most features and greatest functionality.
What is the decibel rating of my air conditioner?
There is no industry standard for measuring the sound of room air conditioners or an independent agency to verify the ratings. Our ZoneAire products follow the guidelines set by AHAM (Association of Home Appliance Manufacturers), but these guidelines do not list decibel ratings for home appliances. Without an accepted industry standard, each manufacturer can â€œtestâ€ for sound ratings using whatever methodology they prefer. And without a common testing method, none of the results provide accurate comparisons. That’s why we do not publish sound ratings.
What causes ice to build up in an air conditioner?
Icing can be caused by a number of factors. Units that have not been cleaned over a long period of time may have coils and fins clogged by dust, dirt or debris. Clogged coils and fins restrict air flow through the unit, which can cause the compressor to work even harder â€“ so hard, that it may reduce the coil temperature below the normal range in an attempt to make up for the lost cooling power from the blocked coils.
Another potential cause is running a unit with a very cold set point (i.e. turning the target temperature down very low) on low fan speed for an extended period of time. This can cause excess condensate to build up on the coils, further lowering the temperature of the coil and leading to icing.
My unit produces cold air but it keeps turning off and on every few minutes, and Iâ€™m never comfortable. What is happening?
Your unit is probably too large for your room and is â€œshort cycling.â€ This happens when cold air from an oversized unit bounces off the wall and back towards the unit, creating a room-temperature reading thatâ€™s cooler than the actual temperature. This false reading causes the compressor to shut off before the room has truly reached your desired set-point. While the compressor is off, the “real” room air enters the intake grille, and the thermostat reads that the room is no longer at the set temperature, so it turns the compressor back on. Your unit cycles off and on approximately every two to three minutes to reach the set-point. While the air coming out of the unit is cold, the compressor does not remain on long enough to cool the entire room.
The only solution is to correctly size the unitâ€™s capacity to the room size and demand. A unitâ€™s capacity is determined by its Btu. Larger rooms need a higher-capacity unit (a greater Btu) to cool correctly. But a unit that is too large for the room will reach its set point too quickly and the compressor will turn off before the air conditioner has had adequate time to remove humidity from the air.
How do I choose the correct unit capacity/ Btu size?
You should consider a number of variables when sizing a unit, such as location, room insulation, how many people will be using the room, size and location of windows, to name a few. Our Sizing Guide will give you an approximate size, or you can link to the AHAM web site, http://www.cooloff.org for a much more complete sizing guide. You also could have an HVAC professional conduct a heat-loss study at your location to determine exactly what type and size unit is best for your application.
I only use my air conditioner a few months per year. Why is my warranty based on when I purchased it?
While seasonal use may result in less wear and tear on an appliance, there are two valid reasons for time-based warranties. First, manufacturers cannot realistically base warranties on use because we canâ€™t accurately monitor when and how you use your unit. Second, some appliances actually age more quickly from extended periods of non-use than from continuous daily operation. For example, refrigerator and room air conditioner sealed systems can stay vacuum-tight for many years if the internal refrigerant gas and lubricant keep moving and softening the various seals. These seals may dry out if the mechanisms involved remain stationary.
