"Home Comfort Systems replaced my old air conditioner with a new American Standard air conditioner. The day it was going to be installed, one of the owners, Steve, stopped by to look at the old air conditioner, and explain what was going to be done. The installers arrived an hour later, explained to me exactly what they were going to do, and all the specs of the new air conditioner. Roughly 2 hours later, they were finished. They explained the warranty, and cleaned up. The only evidence that they were there was the new air conditioner, no debris left behind. They were very professional, and I would gladly use them again!"

"Although it is never good news when you need to replace your heater - the guys at Shavitz have been great to work with throughout the process. During the initial consultation and installation Mike and Jose were professional and corteous throughout the entire process. I would trust these guys again for other HVAC needs!"

"I got several quotes for this project. My 3rd floor masted bedroom is incredibly hot in the summer. I looked into a few option - through the wall A/C units, a zoned system - and decided on the Mitsubishi split system. They are a Mitsubishi Diamond Contractor Elite and I wanted to choose someone that was well-experienced in this install. Besco was awesome, specifically working with Joe Pedota. He explained everything thoroughly to me and gave me a few options. He managed all aspects of the project, including electrical so that I didn't have to hire and coordinate other contractors. I'm supper happy with my system - it cools the whole upstairs and is incredibly quiet. Besco even called to follow-up and sent Joe out just to walk through and see if I had any issues or questions. I couldn't recommend them more - and their price was the cheapest, too! Thanks, Besco...and Joe!"

"Jon showed up at 7:00 am on the dot, exactly 2 days after his initial visit to install my new 2 stage carrier furnace. The price included the materials to raise the unit, the necessary metal work for the ducts, and a new thermostat. The people who installed the first thermostat installed an incorrect one not suited for a 2 stage furnace. He removed and disposed of the old furnace and installed the new one without incident. Jon took the time to walk me through the use of a programmable thermostat and where to place the filters. My basement was left immaculate."

FAQs for swamp cooler installation and replacement projects in Evanston, IL

Swamp coolers are quite energy-efficient, using only 15% to 35% of the electricity that traditional central air conditioning units consume. This can lead to significant savings on your energy bills. However, keep in mind that swamp coolers require water to operate and may not cool your home as effectively in extremely hot or humid conditions. When considering overall efficiency, it is essential to weigh both electricity and water usage, as well as the cooling needs specific to your local climate.

Evaporative coolers only work in dry climates because they cool by moistening the air. If the air is already moist, this will have little to no cooling effect. Central AC is a better choice if you live in a humid climate, such as the Midwest, eastern, or western coastal regions.

To install a swamp cooler on a roof, a local HVAC specialist will first find and cut a spot free of wiring and obstructions. They’ll then install metal bracing, legs, brackets, the ceiling duct register, ductwork, power, and thermostat wires. Once installed, they’ll seal all openings, attach duct connections, and install a thermostat. Before leaving, they’ll run cool water piping to the unit and inspect all the connections.

The cost to repair your swamp cooler ranges from $50 to $600, depending on the issue, whether new parts are needed, and the chosen repair service. Depending on the type of pad your system uses, you will need to change out the pads every one to three years for proper operation. When budgeting for the cost to repair a window unit, expect to pay around $230.

The U.S. Department of Energy states that swamp coolers can cool a single room by five to 15 degrees Fahrenheit. However, this largely depends on the size and installation method of the evaporative cooler. You can only achieve these results in a dry climate, such as the American South, as it’s easier to cool rooms in humid environments with central air.

Swamp cooler water usage varies depending on the size of the unit. Smaller evaporative units may use one gallon per hour, while much larger units could use up to 15 gallons of water per hour. Most homeowners can expect their unit to use between seven and 10 gallons of water per hour of usage.
