"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"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!"

"I called Peterson to have him replace a leaky bathroom faucet and a pop up drain that was in bad shape.  I had purchased the parts, including the feeder lines so the price is for labor only.  Peterson showed up a little early, took about 70 minutes to complete the job and went on his way.  The fixtures were installed as needed with no leaks or problems.  A very simple job for an expert plumber and I could not be more satisfied."

"He arrived earlier and took a full hour to clean and inspect the chimney which hadn't been cleaned in at least 25 years. The chinmay was oil then last yeara converted to gas. He said the chimney had only minor debris and recommended we install liner eventually and a better rain cap and also to add a clean out door.  He addressed why we could need a liner and what to do until we have a liner installed (ie carbon monoxide alarm on all floors).  All in all we are very happy with the service provided and the attention to detail with both the work done and talking about the liner, etc recommendations. We highly recommend Chimney Chap.

"We needed our boiler replaced and had multiple companies come and look at the job. We ended up selecting Sila as we read good reviews on the company. Sila surpassed our expectations. The tech who performed the install (Gage) was on time, communicated the entire process to us from start to finish and did a tremendous job. He also made sure to clean up afterwards and was very professional. We would absolutely hire Sila again!"

"From the first visit to estimate the project, to the final visit to wrap up any questions, issues or concerns, the Walley's team really delivered! Our request was for an oil furnace replacement. In addition, Walley's was able to add central A/C with some modifications to our existing return ducting. The work was completed, to our amazement, in a single day! Everyone, from the office team to the on-site crew, were very thorough and efficient. The email/phone communications back and forth was outstanding! We always had the comfort of knowing that if we had a question or concern, it would be delt with in a professional manner. In our past experience with hiring companies to work on our home, many times, we wouldn't even get a call back! Walley's went out of their way to satisfy our wishes and needs. We were very impressed with the overall experience with Walley's and we would highly recommend them to any of our friends who needed HVAC services!"

"After 8 years, I am in the process of moving out of a house with a large basement to a smaller apartment, with less storage. The size of the basement gave me permission, unfortunately, to pile stuff willy nilly and to store items that I should have discarded. I can only handle the sorting and discarding in pieces. Stephen has been great about understanding my need for him to make multiple trips. I am in awe of his willingness and ability to find the right home for items that can be refurbished or recycled."

"Sooo....first, Jim is a very nice guy.  However, Jim now works in Nashville during the week and is only home to the Huntsville area on the weekends.
My first impression of him was that he was awesome.  My computer system had crashed because I pulled the plug during a thunder storm before the computer fully shut down which resulted in the computer hanging up.  Jim took my call while in Tennessee and suggested how to fix the system.  For this I am very grateful.

What happened next was I had him come and check my computer to make sure everything was working properly.  He came to my house and spent an hour tweaking it (basically running various checks on the system), for which I paid him $50.  He suggested that my laptop would work much better if I had Windows 7 and increased my RAM up to 4 GB.  He said he could install it for me for (including the RAM) for about $160.  We met the following weekend for the handoff and he loaded Window 7.  When I received the call it was ready, the bill was $227.50.  I was surprised that is was $70 more than quoted, but paid it anyways.  When I asked about the RAM, he mentioned he did not upgrade the RAM and this would be another $60.  I was a little discouraged at that point since I felt like I was being taken advantage of, but the guy is relatively nice, so I said to go ahead and order the RAM.  He did so and the following weekend was supposed to install it.  Due to some personal things in his life, he wasn't able to install it, so I picked it up since I had to go out of town and could use the IT guy at my new location to install it for me.  When we went to install the RAM, the system wouldn't let us do it since my particular type of laptop can only take 2GB of RAM max.  If Jim had gone to the crucial.com website (where he bought my RAM) and entered my computer system on it, it would have told him the max amount of RAM that could be installed on that unit.  He did not do that.  He is supposed to refund my $60 this next weekend.

I think if Jim wasn't burning the candle at both ends by having a job in Tennessee during the week and trying to run this business on the weekends, it would've been a better experience.  Perhaps taking a few extra minutes to SLOW DOWN and write out an estimate of everything he would need for the job including the prices would ensure people know up front how much the repair would/should cost so they can budget accordingly.  I think if he had taken that approach, it might've been a better experience.  So now I am stuck with a laptop that runs slower because Windows 7 uses more memory and a laptop that can't be upgraded to more RAM.  Basically, the last step which cost me almost $300 was not necessary.  If you need something simple done like coming back from a system crash, he would be okay to use.  Otherwise, for the bigger jobs, I recommend he provide a written estimate with the items he plans to do.

UPDATE:  After posting this review, I received a number of text messages from Jim commenting on the bad review.  I understand he is upset, but harassing someone about a review is not a good way to go.  My review was honest and not meant to be mean, but to let those that use Angie's list get what they pay for...an honest review of someone's experience."

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