"Woke up to no hot water on Friday. I immediately starting thinking, "I'ts Friday, I won't even get anyone out here until Monday." I called Joyce Cooling & Heating and was told that they would have someone out that day, and that the Technician would call a half hour before arrival. Sure enough, the Technician called that afternoon and arrived right on time. Our Technician Josh, diagnosed the problem, and had us up and running within an hour! Josh was very professional, explained the problem and left the area neat and clean. I was also very happy with the cost of the repair. Thank you Joyce Cooling & Heating!"

"This was among the best experiences I have had with any third-party contractor, period. We did an expensive central A/C replacement. Seashore Comfort was knowledgeable, responsive, professional and technically proficient. We needed a 20-year old A/C unit replaced. I called four area HVAC specialists and almost didn't call Seashore because they had relatively few online reviews (although the ones they did have were positive). Turns out the company was started relatively recently by a veteran tech and his wife, who worked locally for a couple of decades. Every aspect of this project was impressive - from the front-office communication to the quoting process to the technical description of what are options were to the quality and craftsmanship of the install. Furthermore, I _almost_ went with a different quote from the local "giant" and that would have been a huge mistake. It took quite a bit of technical research and education on my part but what that company was proposing would not have been the best choice of solution for our application. That would have been a costly, long-term mistake. So, in short, this is a scrappy young company with the all the benefit of experience of a much older company. Proceed without reservation."

"Don was great to work with.  It was not a major job, but because we chose small glass & stone tile and wanted it installed vertically it was very detail intensive.  Don made sure it came out exactly as we envisioned it, even after other potential installers had told us it would not work, and his pricing was extremely competitive.  He was very pleasant while on site and left the house spotless each night.  We will definitely be using him again for our next project.

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

"I had a written estimate within 24 hours of my initial phone call to them for a complete HVAC replacement. The estimator arrived on time and made a point of first listening to what I thought I needed and what I wanted to get from my new system. He then gathered details of what was existing and came up with a proposal based on what was needed as well as my concerns. the installers were on time, they cleaned up extremely well when finished and the equipment looked great. They made a follow up call after a few day's to make sure all went well and asked if I had any concerns or issue. I did not. In my own job I manage 15 installers and technicians and I know very well what good customer service is. George's delivered by all measures and I would readily recommend them to anyone."

FAQs for swamp cooler installation and replacement projects in Chester, NH

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.
