For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

FAQs for swamp cooler installation and replacement projects in Stow, MA

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.
