"The project went well. There were some leaks after the initial installation, but these were fixed before any damage was done to the ceiling and wood flooring."

"I have been a Palmer customer for 5 or 6 years at least. My experience with the front office and the technicians has always been great. We have always been on automatic oil fill and we have never had an issue. My most recent experience was today - we needed a service and a replacement part. The technician was very polite, experienced, knowledgeable and respectful of our time (David). He also had a more junior team member with him (Domenic) who was very respectful as well. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Excellent for maintenance service and emergency work. I subscribed to their maintenance service for several years before they raised the rate, and they always did fine work. When I switched to another maintenance company that missed a flaw in my furnace which caused it to fail on season startup, AccuTemp came out to diagnose the problem the same day with no contract, got the large expensive replacement part for free under warranty, and had it fully installed and working again within 2 calendar days. All that for just the cost of a day's labor!"

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"We own a home in Gloucester that we rent out during the high season. During the hottest week of the summer, two of our central A/C units broke down and we needed to replace them fast. I called ten different A/C companies on a Sunday night—and was amazed that I reached SEASHORE COMFORT SOLUTIONS directly. Sarah sent out someone from their team the next day to do a diagnostic; we ended up replacing the two units within days of that first visit. Every time I called the office, someone answered. Every time I wrote to SEASHORE COMFORT SOLUTIONS, I received quick responses, clear answers and very courteous service. They deserve FIVE STARS every time. When the units were installed, the tech called me about the wall mount placement and then again to tell me they were leaving. SEASHORE COMFORT SOLUTIONS was so easy to work with and I'm relieved to know that they are nearby and ready to help when needed. Thank you to Sarah, Rich, Frank and everyone on the SEASHORE COMFORT SOLUTIONS team!!"

"A godsend for those annoying jobs that are too random for a general contractor but too big to DIY (or you just aren't getting around to it!!). Joseph's team can solve a lot of problems. Not every problem, but I have yet to think of one they can't solve."

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