At Aspen Creek Heating and Air, we want to share everything you need to know about evaporative coolers. There are many benefits to keeping a healthy and fresh air environment in your home throughout the summer, even as the temperatures outside climb. Evaporative coolers are effective, economical, and are an environmentally friendly way of cooling down your space.
There are some restrictions as to the appropriate uses for evaporative coolers, however, and they must not be used in closed and unventilated areas. They rely on a flow of fresh air, enabling them to work. If they are utilized in an unventilated area, they will simply pump humidity into that space, making it very damp. This may be damaging to electrical systems and belongings.
HOW DOES IT WORK?
Evaporating water into the air provides a natural and energy-efficient means of cooling. Evaporative coolers, also called swamp coolers, cool outdoor air as it passes over water-saturated pads. The air is cooled 15°F to 40°F and is then directed into the home, pushing warmer air out through the windows. When operating any evaporative cooler, windows are opened part of the way allowing warm, indoor air to escape out as it is replaced by the cooled air. Central air conditioning systems, however, recirculate the same air, while evaporative coolers provide a steady stream of fresh air into the home, providing a healthy and safe environment.
WHAT ARE THE BENEFITS OF AN EVAPORATIVE COOLER?
ECO-FRIENDLY: Low to virtually no chemicals are emitted into your home using this method, and it won’t dry out your space or your nasal passages! Stale air is always replaced with fresh air and never recirculated.
INEXPENSIVE INSTALLATION: A licensed contractor can install a unit anywhere between $700 and $1100, depending on the area in which you live. That is dramatically cheaper than a traditional air conditioner unit installation.
LOW MAINTENANCE: A water pump and fan motor are the only two parts that would ever need replacement in this unit. For that matter, you could probably do it yourself with the help of videos online. It is recommended to schedule a service about twice a year, or more depending on the amount of use. Some ways you can keep costs down is by draining and flushing reservoirs, cleaning pump screens, checking for cracked tubing, and adding oil to the motor. Of course, Aspen Creek Heating and Air is always there for a repair or service call.
LOW OPERATIONAL COST: Regular AC units require a lot of electricity and moving parts replacement; an evaporative cooler cuts your monthly cost in half because there is less to break, and the parts and labor are inexpensive.
FRESH AIR: Evaporative cooling helps increase humidity in your home, and when you live in a dry climate it will help you breathe in purer air. The pads in evaporative coolers also serve as an effective filter which helps catch airborne contaminants before they make their way into your lung system. Eliminating urban ozone contaminants from the air is an added benefit of these systems, as dryer climates tend to be more susceptible to these toxins.
LOW CARBON DIOXIDE EMISSIONS: Very little CO2 is emitted from an evaporative cooler, unlike the traditional AC units which are quite high. So, not only will you help the environment, but you will help yourself stay cool!
DOORS AND WINDOWS OPEN: No one likes feeling trapped in their home, especially during the summer months, so open those doors and windows, and benefit from the fresh air that awaits you, because your evaporative cooler thrives on the fresh open air. AC units, as you know, require a completely air tight environment, drying out your home and your body.
ADDED MOISTURE: No one wants to dry up like a lizard in the desert! Another plus of your evaporative cooler is it provides moisture to your home, your body and the air you breathe.
QUIET: You won’t hear much noise coming from your unit. Sleep like a baby and wake up refreshed!
WHAT ARE THE DRAWBACKS OF EVAPORATIVE COOLERS?
Do not use evaporative coolers in humid climates. They add humidity to the air. They cool the space down to a higher temperature than an air conditioner would, and require simple maintenance about once per month. If the evaporative cooler is installed on the roof, there will be some roof deterioration caused by routine maintenance. They also use a continuous amount of water, so if water is a concern in your area, this may not be the best option.
WHAT TYPE OF EVAPORATIVE COOLER DO I CHOOSE?
The fact is, there are many choices out there, but the best route is to ask Aspen Creek Heating and Air the best options for your family and home’s needs. Here is a sampling of what is available:
- Direct Evaporative Coolers: Help to cool down surrounding air and release it into the space, helping increase humidity and remove stagnant air.
- Indirect Evaporative Coolers: These units will use an evaporative media inside of a cooling tower. This will help cool water down to the temperature that is already in the air.
- Up-Draft Units: These units, usually installed on the floor, blow cool air upwards into the home.
- Down-Draft Units: A downdraft unit is mounted on a roof, and will blow cold air downward into your home. These are the most popular options, but they can be the most expensive and time-consuming to maintain.
- Side-Draft Units: A side-draft unit will be installed on the side of a home, usually in a window, and will blow cool air into the home, such as a window-mounted air conditioner might do.
- Standalone Systems: Standalone systems require designed ductwork.
- Combined Systems: These units require sharing of ductwork.
- Portable Evaporative Coolers: Great for smaller living areas or individual rooms.
