"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"I needed 2 dryer vents cleaned - one on the 2nd floor and a vent cap replaced (also on the 2nd floor). All the companies I initially contacted would not do the job for a variety of reason. Superior did all the work I needed plus replaced the dryer hose on one unit (which we had not discussed). Additionally, I had purchased a vent cap but it did not fit. Superior had one on the truck which did fit and they got the job done! Excellent service!"

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"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."

Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

"I had a lot of additional cost. It ended up at $1500. They only cleaned three, for the big deal. And then, I had a thing that they put in to make sure that the air stays clean. They said I had a humidifier on my furnace and they said that it had to come off. And then, they said you can get a much better one and then they kind of disappeared and they didn't talk about it or really sit down and have a conversation with me. I'm not even sure why they had to take it off or what they did."

FAQs for swamp cooler installation and replacement projects in Dover, 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.
