"There team did an amazing job, moving the dryer out, replacing tubes as needed, and going into attic, and outside to clean the vents, as well as thoroughly cleaning the inside of the dryer. Moved everything back perfectly, and left the place spotless. Dryer functioned 100x better."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer 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."

"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."

"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

"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."

"DiPietro has knowledgeable technicians that have been good at resolving any problems with our heating system. This includes fixing some issues we experienced with the NEST thermostats. I do suggest that you ensure that you are given a full explanation of any potential charges prior to the work being done to avoid any surprises."

"Gill was excellent, called within the hour of me finding his number thru Angie's list (TYVMBTW). swung by well after dark on the way home from another job on a Friday before a Holiday weekend. Solved problem quickly. Extremely knowledgable. did I mention the Extremely Good Price too... Another Big Plumbing outfit came by 2 days prior and although I tried, they didn't want to touch it, risk and all that, but they did happily quote me a new system. Gill is my go to from now on."

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