"My experience with Greenwood Heating and Air Conditioning has been entirely positive. From my free estimate appointment through finished installation, the process was seamless. Each and every representative of theirs has been exceptional. Trevor negotiated a very competitive, all inclusive price for the entire system and followed up on the day of installation to see how everything was going. The install was expertly performed by an industry pro, Andril, with 17 years plus experience. Follow-up has been exceptional. Greenwood Heating has earned my unequivocal recommendation."

"It went very smoothly. Seemed like a straightforward routine job. It took about 2 hours to remove and replace my 50-gal water heater. The company was very proactive with communication. It seemed a bit steep at ~3k but I didn’t shop around so I can’t say for sure."

"Our Heat pump was not providing cold air so I called for a repair person to come out and fix it. Evergreen was able to provide me same day service which was impressive and the tech Alec Smith was very professional and skilled. He had the main issue diagnosed within probably 20 minutes and had a replacement part on hand. My complaint with Evergreen and this is probably common throughout the industry is the markup they put on those replacement parts. I needed a dual run Capacitor for which I was charged approximately $175 dollars. After doing a little research I found that this is a $21 part from Grainger or Amazon. That's one **** of a mark-up. I can tolerate a mark-up because of the convenience but I feel 800% is excessive."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"I'd been wanting to get of our old electric baseboard heaters for a long time, and replace it with something more efficient, and Mark helped my understand the differences between a ductless mini-split system and a ducted heatpump system. Even in our small house, the ducted system was the way to go. Mark and his installers were professional and efficient, and answered all my questions. When the thermostat was acting a little odd, he sent a technician over to calibrate it, free of charge. There was a small issue where I initially got the wrong specs for the electrical, and as a result I had the electrician install unnecessary circuits, but Marc reimbursed me for the cost."

FAQs for swamp cooler installation and replacement projects in Mercer Island, WA

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.
