"Everything went great. The crew arrived right on time and was very polite and professional. Ali explained everything beforehand and the work was done exactly as described. After installation there were some minor adjustments to be made and Ali responded right away and took care of the problem. He was also able to get the ducting corrected to a part of the house that hasn't had ac for many years. I was very pleased with Ali and his crew."

"These guys are great. They came to assess the situation (problems with our oil furnace) and thoroughly reviewed options. We went with them for a furnace replacement, as well as a heat pump to replace our standard a/c units. They came in much cheaper than the two other companies we consulted (one of which we had used for almost 50 years (since the house was new). We're thoroughly happy with our new HVAC setup, and even the fancy Nest thermostat. Highly recommended!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"I'd become increasingly concerned about the company I was using for my AC and heating needs. When I knew we needed a lot of work doing, I decided to search for a new company that I could trust. We needed to get 4 new AC units installed. They were 17 years old and leaking, so we took the plunge and decided to replace them. I had a lot of questions around the systems in my house and what to install. During my phone conversations Donny was extremely helpful and patient. He answered all my questions and I believe that he gave me honest suggestions on the best solutions for my home and living situation. I found him to be honest, trustworthy and very knowledgeable. The install went smoothly, one of the units was tucked away in a tight closet in my daughters room, and they dealt with that easily. They installed 4 new controllers. They were tidy, and worked long hours to get the job done. In addition they spent time explaining the new systems to us and answering questions of ours that arose. We are really pleased with the new systems and controllers, we have peace of mind that we've installed good, reliable systems, and that we have a great company looking after our AC and heating needs. I also hired them to do annual service visits for our heating and AC. So far they have performed the winter maintenance visit, and identified a couple of things that needed addressing to prevent possible problems this winter. What they recommended made sense to us, and we thought they were valid and worthwhile repairs. As we trust this company, we decided to go ahead and get the work done. Chris D came to do the repair job. He was very friendly, helpful, hard working, and did a great job. He also took time to make sure we knew what was going on. I'm hugely relieved that I found this company. It's increasingly rare to find companies to help out in the home who are good at what they do, honest and trustworthy. I highly recommend them. BTW I'm also impressed with their office support staff. They are super friendly and helpful, calling back when they say they will. Booking appointments is super easy with this company."

"From the initial proposal and questions with Kevin to the installation with Mike and Milt, the professionalism and knowledge sharing was remarkable. To have the owner, Kevin, involved was a key influence in decision, as was our neighbors high positive regard for Ryan & Co. The installation was efficient. Mike and Milt were so organized and kept things neat and clean. They paid attention to detail and fixed the ancillary to the main system where needed. High quality all around. The system is in and can’t wait to see how it works, especially through the tricky up and down temps of the fall season. Farewell to the 35 yr old system."

"Shai was very friendly and gave us the best price. His team worked on installation in a day and everything was functioning smoothly thereafter. We did have a concern about pipe placement and when I texted him about it, he answered right away and ensured he'd remediate the issue. He was always available by phone, text and email for scheduling. The pipe was moved with condenser. Everything looks good. Thank you!"

"Since this was an emergency (we were concerned that the pipe might crack with no support) we went with Universe as that was the first company we contacted. The service manager (Tommy) sent over a tech (Nick) within 2 hours. Nick proceeded to remove 20ft of old pipe and replaced with new PVC and new support straps. The job took about 5 hours including the assessment and cleanup. The service was performed very professionally. We did pay $2,700, which we feel was a quite high for 5 hours of work. But, since we didn't get competing bids we can't complain."

FAQs for swamp cooler installation and replacement projects in Greenwich, CT

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.
