"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"Used Sila for two central AC installations and misc repair calls. Quotes for the installations were probably not the lowest available but I have been impressed with the skill and efficiency of their technicians and they have always been very responsive on any service calls. Installations were very well done and unique challenges met with intelligent strategies. I rate Sila highly and would certain use them again."

"I am so pleased with the exceptional service and quality of service. Reliance Repair scheduled an appointment at the time I requested, and explained all of the options regarding the dryer. The service for replacement of the part was performed within a day or so, and again, the service professional explained everything, and ensured that I was satisfied. Both the cost and the warranty terms were reasonable."

"The service that they provided was good and we would call them again. The driver arrived at our home on time and we got to the airport with no problems. I would just recommend calling them a day or two before your trip to confirm."

"I spoke to Walt about doing an estimate to remove mold that resulted from a leak in our garage roof. Although we were slightly outside of their service area, Walt was agreeable to coming out as I was having difficulty finding and/or receiving a response from other companies with the proper mold removal certifications. Walt was able to fit us into the schedule quickly and was friendly and professional during his visit to perform the air testing and gather the necessary information to provide an estimate for the mold remediation. He contacted us promptly both by email and phone with the estimate and was able to schedule the job, all within a few days.
Kurt supervised the job and went above and beyond the call of duty. Prior to his arrival, we had not yet been able to confirm the source of the leak in the roof. Our roof is quite complex, having many different angles and being steeply pitched above the garage. A roofing company had attempted to locate the leak, but had been unsuccessful as well. Although this was not part of the service, Kurt (an experienced roofer) spent considerable time trying to find the source of the leak himself using our garden hose. He was able to isolate the area and when we called the roofers back, they concentrated on that area and were finally able to repair the roof. It's been a little over 6 months since all the repairs were completed and we've had no further water damage or mold growth. I gave AHS a rating of "N/A" for pricing as I cannot compare their pricing to other companies, who had an opportunity to provide additional estimates, but never responded to inquires. We highly recommend American Home Services.

"I needed the splash guard replaced on my 2007 Honda Civic in a hurry because it was dragging on the ground. My boyfriend and I have been regular ABS Unlimited Auto Repair customers for about two years, so he called them on Columbus Day to see if they could squeeze me in. They said to come right in. When we went in, Tom took a look at it, called the Honda dealership and ordered the part. ABS had it installed by the afternoon. The service was great.
The extraordinary part came when I went to pick up the car. My bumper had become detached on the drivers side a few years ago when I was parked at the Metro. ABS professionally reattached the bumper at no charge...without even telling me! I continue to be delighted by their excellent service. Everyone on the staff is very friendly and helpful. Thank you ABS!!!

"I don't know which part needs to be repaired. So I bought both toilet water tanks. They came and replaced it but they close the door, I guess they don't want me to see how they repair it. It stopped the leak, but the other part started leaking again after 1 year. But the price is good."

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