"We needed the 32 year-old ductwork replaced in our second story due to heavy infiltration of dust, pollen and bits of fiberglass insulation from the unfinished attic portion from deteriorated ducts. Given our pretty severe allergies to tree and grass pollen, the second story rooms were mostly unusable and even the first floor a problem, not as bad but still unpleasant. Even our cat was suffering. Drew, the sales manager, gave the whole system a very thorough review. He measured our rooms and discovered the system was oversized for the square footage, which not only put strain on the blowers but made the sound at the registers so loud it was difficult to speak on the phone in my office. He recommended an additional register in the hallway between the rooms. Glad he did. The thermostat is located in the hallway which also looks out over a large room with a cathedral ceiling. The new outlet has helped normalize the temperature and the AC/Heat run much less now and give more even temperatures. He also recommended a full house filter on the blower and an in-duct LED purification device that treats mold, dander, pollen and dust. Again, glad he did. They have made a big difference very fast, especially in pretty dramatically reducing dust and improving our respiratory systems. We had the same devices installed on our downstairs unit. We also had a detached first floor duct. In an above and beyond move, Drew went into the crawl space to check it out and temporarily repaired the duct until Maynor could replace it. The installation team, Jeff and Seth, were the superheroes of the project. There were two ducts so tight under the roof they looked as if they couldn't be replaced without tearing out part of the ceiling. One of those ducts had been shredded all the way through by an animal. It came out right over my desk and had been raining pollen, etc. down on me for some time. Seth managed to squeeze into the tight spots and replace the ducts all the way to the boxes. Both guys were very professional and personable and did a great job as unobtrusively as possible in a single day. Also very proud of the company and obviously happy to work there. Maynor sounds like a very customer and employee focused company."

"Excellent. The crew was on time, were Covid prepared, and very informative re costs and what they could do. The part was ordered and installed in a week. Despite the cost of the part, they recommended that we keep our machine because, in their experience, Maytags of that vintage were far superior in reliability than a replacement would be. We trusted their straight talk and they came through."

"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"Lahcen found the leak quickly, sourced a new coil and installed same. He did an excellent job and explained the various steps in detail. He was open to related dialog in a positive way. Highly recommend him for his knowledge, skill, experience and commitment to get the job done right, and on time."

"I am now a fan of The Water Specialist. I am a property manager and one of my tenants complained that the grinder pump siren was continually going off. I called several places who either never called me back or couldn't come out right away. It was a weekend and I spoke with Ryan at The Water Specialist who was so incredibly helpful. We were calling/texting back and forth throughout the day and he was trying to get someone out right away to pump the well. It took a little too long for me to get a hold of the owner and I missed the opportunity so we used another vendor to pump the well. But I got an estimate to replace the grinder pump from both vendors and I was happy that The Water Specialist came in just a bit lower so we went ahead and had them replace it that week. I really wanted to give them the business since Ryan spent so much time helping me for free. He continued to stay in communication with me throughout the process and I was able to keep the owner and tenants updated and happy. I called them again today to help with another property and they were very friendly and responsive. Highly recommended!"

"Vendor install a Honeywell 7200 series thermostat in my new home, but I decided to upgrade to a 6580 WiFi unit. I did all the work myself but couldn't get the A/C to work. I called Honey well who referrred me to Enhanced Heating and A/C. I called them at 3:45 PM on a Friday afternoon and got a live person who said someone will call me back after I presented the problem I had. Around 4 PM I got a call from Sean who helped me out with the wiring and the A/C is now working."

"I can give the highest rating for Matthew because he's an all-around good guy. He repaired my propane unit for about 1/5 of what JD Service Now wanted to charge me, and he did a great job, and spent a lot of time getting it done right. He's the kind of service guy that you feel like you've not only gotten your furnace fixed, you've gained a friend. I'll hire him for my next HVAC need."

FAQs for swamp cooler installation and replacement projects in Apex, NC

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.
