"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."

"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."

"Needed to replace my home a/c and GMR Mechanical visited my home quickly. We discussed the options and was quoted a price on the spot with the available installation dates. Their prices were reasonable so I hired the company for the A/C replacement. The work completed by GMR Mechanical was excellent, cleaned up and were very polite. I would hire again."

"We recently had a complete roof replacement. Before proceeding, we did comprehensive research of area companies and Vista came out on top, with good reason! All appointments were not only on time but were extremely punctual. We met first with Product Specialist Holly, who was enthusiastic, very knowledgeable and helpful. While at our home assessing the proposed job, Project manager Rick explained the entire process in layman's terms. The day of the job, Project Supervisor Marc arrived early and went over the entire job with the crew. All company representatives left us with a business card with their cell #'s to call if we required anything. The installation crew was amazing. They arrived early and began immediately. They were no nonsense, very focused and, worked like a well oiled machine. All Vista team members were polite and respectful of my special request to be cognizant around some of my more cherished trees & shrubs. Vista was fastidious in their care for my home and lawn, not one speck of debris was left behind. Vista, the installation crew, company representatives, everyone, exceeded our expectations. Vista stands behind their work and products. If you wish to relax after a major home improvement project knowing the job was done correctly, you will want to consider Vista. Dan & Kim Belchertown"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

"Leo did an amazing job, and the area looks better than I ever thought imaginable. He was very professional and prompt, and would absolutely hire him again, or recommend him for other jobs."
Our main focus is to solve the problem, in this room we had to wait for the home owner frame the closet before polyurethane the floor. One more problem solved.

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