"Everyone from Presidential has been friendly and helpful -- great customer service! Glenn came to our home to discuss options to replace our furnace (fuel oil) and AC systems with a heat pump. He immediately understood that we were looking for a heat pump eligible for the new tax credits (unlike another company, who only provided estimates on what they had in stock). He prepared the estimates for 3 different models on site, and he noted that the heat pump eligible for the tax credit would cost about the same as an older model (unlike what the first company told us). We were able to schedule installation quickly, and then the adventures began. Harvey and Andre were here for 12+ hours...because a wire was either never connected at the factory or came loose during shipping. We also had to replace a defective line from our house to the unit. While it was a complicated install (not the fault of Presidential), we rec'd great service from hardworking staff members. Highly recommend!"

"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

FAQs for swamp cooler installation and replacement projects in Gaithersburg, MD

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.
