"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."

"I had a written estimate within 24 hours of my initial phone call to them for a complete HVAC replacement. The estimator arrived on time and made a point of first listening to what I thought I needed and what I wanted to get from my new system. He then gathered details of what was existing and came up with a proposal based on what was needed as well as my concerns. the installers were on time, they cleaned up extremely well when finished and the equipment looked great. They made a follow up call after a few day's to make sure all went well and asked if I had any concerns or issue. I did not. In my own job I manage 15 installers and technicians and I know very well what good customer service is. George's delivered by all measures and I would readily recommend them to anyone."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"THEY WERE THERE ON TIME AND TOOK A TOUR OF THE HOUSE TO CHECK LAY OUT AND COUNT THE VENTS. WE HAD MORE THEN THE DEAL ALLOWED SO THE PRICE WENT UP FROM 89.00 TO AN ADDITIONAL 230.00 DOLLARS. THEY HAD SOME EQUIPMENT ISSUES,  THEY WERE NOT REALLY SET UP TO REACH SOME OF THE VENTS IN OUR HOUSE. THEY ALSO WERE IN NEED OF A NEW BRUSH, THE ONE THEY USED WAS PRETTY WORN.
ON THE UP SIDE THEY WERE FRIENDLY AND WORKED STEADY GOING FROM ROOM TO ROOM IN ORDER TO COMPLETE THE JOB IN A TIMELY MANNER. I FELT THE PRICE WAS A BIT HIGH TO ADD FOUR MORE VENTS AND A RETURN, THE WORK WAS COMPLETED AND I HOPE THAT WE DON'T REQUIRE THIS SERVICE AFTER MOVING INTO OUR NEW HOME.

FAQs for swamp cooler installation and replacement projects in East-derry, 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.
