"I hired Alliance to complete several jobs in my newly purchased home including: 1. bringing bathroom and kitchen plumbing up to code, 2. installing a garbage disposal and faucet, 3. installing a new toilet and fixing plumbing to toilet, and 4. multiple pinpoint leaks and pipe corrosion in the basement plumbing. From the start, it was such an easy and stress-free process. Communication was constant through email and text about the service dates and ETA of the team members, which was fantastic as I was traveling back and forth between my current and new home. The estimator (Mike) was at my home the day after I made the initial call and walked through everything with me in a friendly, well-informed, and pressure-less manner. He never tried to upsell me and, in fact, helped me prioritize the most important items to address. The plumbing technician (Andrew) was at my house five days later with all of the required materials and worked for 8 hours on the various items. He even found and fixed another broken component while working which probably saved me additional stress and money! At the end of the service, he walked through all of the fixes, went over the warranties associated with them, and ensured my satisfaction before processing payment. He was so impressive that another contractor working on the painting in my home asked him for Alliance's business card. I would hire Alliance again for any plumbing need and would recommend them without hesitation to friends, family, strangers, or anyone else with plumbing needs!"

"The line was in the rafters of a high ceiling of the cellar. It led to an outside gas line (for a gas grill hookup) that was capped off at the house. I wanted to replace the valve rather than cap it off. This was a two man job of a plumber, Rob and his assistant. Rob had to get into the window well and work above his head in a very cramped space. This was complicated by having a large porcelain washtub directly under neath it, blocking access. Rob was extremely careful when climbing to get to the valve. They put down a plastic sheet to protect my washer and the sink, and used their ladder to get over to the wall and window well. Rob cut out the valve and put in a new one that is easy to open and close. He had his assistant check the position of the outside outlet as he worked until he adjusted it so the outside outlet was not turned askew. Btw It was raining and his assistant noticed mud on his boots, and asked for a paper towel when we got in the house...he used it to wipe up his footprints from the mud from his shoes as he walked... Rob checked for leaks and found none. They took any of the debris with them, and left everywhere they were spotless. Also, their last job was running longer than anticipated, and they called to let me know even though at least 30 minutes before. It was only about 15 minutes. Well mannered and professional...Could not have been better!

"After two weeks of trying to diagnose the problem with my heating system, it was determined that I needed to replace the system. Although this was not the answer that I was looking for, it was the right answer and decision. From the technicians who determined a replacement was needed, to Phil Grego who coordinated the replacement installation, to Miguel and his coworker who worked quickly to replace the system, it was a flawless coordinated effort to restore a working heating system in my house. All representatives from Arctic Air were respectful and informative. An extra shout out to Phil who was able to get me on the installation schedule quickly."

"It took 2 days to do the work. Larry and his crew went meticulously piece by piece and installed all the new equipment. They did it so quietly, neatly and perfectly, it was as if they were not there. Any item that needed my imput , such as location of thermostat, they asked questions to clarify. I could not have been happier with their professionalism, politeness, and quality of work."

"Repairman, Andrew, came and located the problem. The ignitor had burned out, so the burners would not light. Andrew did not have the part in his truck but was able to fit in a used part from another furnace to give me heat until he got the other part. I got a call the next day and scheduled a time to put in the exact part. Again, repairman was within the stated time window. Heat working well."

"The second attempt was on time and installation was smooth and quick. My bedroom was saved from the hottest and muggiest days of the summer.
I am writing this to amend the previous review which was late and then encountered problems with my building.
Coary made it right.
Thank you.

"Completely Satisfied, will use again !! The technician Thomas was very friendly and professional. He took pictures of my dryer vent before the job started and after the job had been completed. Thomas explained each step along the way and thoroughly cleaned up when the work had been completed. I am very pleased and highly recommend Green Ductors."

"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."

"It went very well! The crew was fast, hard working and respectful. They got everything put in smoothly and installed a NEST thermostat we had purchased on our own. It couldn't have been easy as the unit was in the attic and the only way up there is a pulldown ladder. They even took the time to inspect the HVAC we had installed during the pandemic by a different company that we had concerns about. They identified issues, talked to us about it and then fixed whatever they could. Bob also identified insulation issues with our attic which was causing us to lose heat in the winter and cool air in the summer. We are planning on have them return to take care of it."

FAQs for swamp cooler installation and replacement projects in Allentown, NJ

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.
