"Our furnace and air-conditioning system in our home was almost 23 years old and this winter the furnace started having issues. I have used Sucoy and air in the past for air-conditioning repairs and I liked the way they did their work. They explained exactly what was going on and what it would take to fix it without trying to upsell me or cut corners. So I knew when I needed to replace my HVAC system at some point I wanted to use this company. They're a small business and locally owned and operated. The two technicians that came out to replace my system did a fantastic job. I have an attic installation for my furnace unit so I know it's not an easy job to do. They were efficient, courteous, and kept us informed the whole way. They did a little things like making sure to put on shoe covers every time they came inside the house and making sure to tarp over clothes in the closet where the access door was for the attic. The carrier system that they installed comes with a 10 year parts warranty and a 20 year heat exchanger warranty. They also provide free maintenance for up to a year as part of the installation. I would highly recommend Sucoy and Air for your HVAC needs!!!"

After a beyond horrible experience with one of the Airport endorsed (shared) Van Services about a year and a half ago, I did not want to go with them again (or ever again for that matter!) and looked for an alternative on Angie's List.

Michael answered my phone call and arranged the trip for the following day confirming it by text message right away after I had send him details like my name, address and pick up time in the same way.

He himself showed up 5 minutes ahead of time in a big, clean car (with excellent AC on a above 90 degree humid day!), gave us all the time we needed to get ready, helped with stowing and unloading the luggage and gave us a very smooth ride to the airport.

Michael has been very well mannered, friendly and helpful to us and we are extremely happy with his service.

"They are excellent. We've used them for 30 years. They have done just about anything and everything we've had to have done with the car. 

Their price was $59.98 for the service, not including the price of the battery. And they gave me a senior discount. Compared to what other people say, I think they are probably fairly ordinary in the pricing and they are always giving me a senior discount or something. So I am pleased with the price of everything. 

They have immediate response. I've used them for 30 years and I'm not changing now."

"I’ve used Drymount Air multiple times for multiple projects. They installed a new water heater, added a humidifier, disconnected and reconnected my air conditioners during a patio installation, put in new smart thermostats and various plumbing jobs. They have always been upfront and honest about what I should and shouldn’t do and given me multiple options. When is used to get multiple estimates, they were typically the lowest, I now don’t even get other estimates. They have always arrived on time, sometimes early squeezing me in during a lunch or between customers. They are courteous and during the pandemic have taken all safety precautions. And lastly came late in an evening to help with an emergency and did what was necessary to get me through the night and came back the next day to finish. They are the first call I would make if I needed anything and would be lost if they were unavailable. I highly recommend!"

"Promptly returned email regarding service request, on Saturday. Responded same day to repair 2Ton Geo unit (Waterfurnace). Extremely knowable on geo-thermal systems, the repairs were made in timely manner at a fair price, my only regret on this geo unit is I should have had Continental install the system in the first place, it’s seems very likely I would not be haveing the maintenance issues."

"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."

FAQs for swamp cooler installation and replacement projects in Welcome, MD

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.
