McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."

"Edmond responded right away and listened to my explanation of the issue over the phone. It was Friday afternoon and we both agreed the issue was non-urgent so we scheduled an early Monday morning visit. He showed up at 8a sharp as we agreed and he did a thorough check of our AC system. Edmond is very knowledgeable and he explained everything thoroughly. He gave me a couple of suggestions. I’m pretty handy so I’ll try to tackle it myself. He said to just call him if I get stuck and he could either come back out or coach me over the phone. Pricing is reasonable and quality of service is top-notch. I’ll keep them on speed dial and I highly recommend Hecomo for HVAC service!"

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