"He's a really friendly guy, very responsive to my calls, schedules me in partly because we've had a working relationship for like six years. He's done work at the house that I live in. He replaced a furnace there and the air conditioner. The day before the warranty of the air conditioner that he had installed ran out, he installed a new one and it didn't work either. He went to the local manufacturer's distribution and got a third one and it didn't work either so he went and got me a brand new upgraded unit and a discount for all the inconvenience. He's a good guy and I have no complaints whatsoever. Sometimes, some of the worker bees that he sends when he is on a job and somebody has to come and check something, they come right away but they are not necessarily as diligent as he is."

"They had to replace and install the new heating system. They are wonderful and we have used them probably for over 10 years now. They are available day in and out. They are I believe a smaller company so if there is any issues and anything to discuss, you have the ability to talk to the owner. They actually replaced the heater one time before and it was a bad unit. It wasn't anything we did or anything they did, it was just that the unit was faulty. The whole unit flamed up our heating system. They came out and completely replaced the unit; they actually fixed everything that was screened for coil, I guess it's commonly known among these people and they didn't charge for that. This happened about four to five years ago. They are just very good and gave a very good deal as we were using them for more than 5 years. We told them to purchase a new unit, but they replaced it with a very good deal. They are just a great set of people. Overall the experience was excellent and will continue to use them."

"I highly recommend Insulation Pros of KC for your insulation needs. Kyle the Sales Manager: made it easy to understand what I needed. Josie the Office Manager: took the time to answer my questions when I called, and was the one responsible for my decision to go with Insulation Pros. The installation crew: Devon, Tyler and Leo were a great team to work with, very personable and just all around nice guys who did a great job with the installation. Tanner - the Production Manager, who came by to see that everything was going like it should. From the first meeting with Kyle to the time the crew drove away, it was easy and pleasant to work with this company and they did a great job. Attached are pictures to show the 22" of insulation in my attic! :)"

"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."

"He was prompt and everything went great. Actually I called them the day before and he installed next day which was great for me! Extremely fair prices and very professional. The final installation looked great and it works like a champ. He answered all my questions and explained everything that he did. I will hire again in the future as he does great work at a fair price and will explain if you are curious like I was."

"Overall, everything went well.  He arrived on time.  He was very conscious about cleaning up after working. The outlet in my garage and the bathroom light fixture were a challenged to install so it took him about 90 minutes to install it. The light fixture needed a box but he managed to run a wire through the dry wall to install without using a box.  He spent about 30 minutes to replace the two electrical boxes which had worn out.
He appeared to be very honest and he did great work.  His prices were reasonable too.

FAQs for swamp cooler installation and replacement projects in Grain Valley, MO

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.
