"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"After fruitless attempts to even get a plumber to return our calls, we found Easy Flow through Angie's List. Mr. Robert Magliulo responded the same day! He was cheerful, friendly, and eager to be friendly and accommodating. He came the next day to evaluate the problem and to provide a written and reasonable estimate. Upon tackling the job, Robert found it to be more ticklish than originally thought. He was absolutely correct. It involved a shopping trip for additional supplies so that the finished job wasn't jury rigged. Despite the extra time and trouble, the final price did not change from Mr. Magliulo's estimate. The finished job proved to be a safe and professional solution to a serious problem we hadn't even been aware of. Mr. Magliulo made certain that we knew we could call on him if there was any problem. There hasn't been. We were delighted and grateful. I would recommend Easy Flow to anyone requiring plumbing services!"

"I had problems with A/C intially and they took care of it. A few months later, they pinpointed the unit that failed, and took steps to get a new unit to replace the bad one. They worked today to get both units heating and cooling. The company is very fair in pricing. Thank you AJ and Sam!"

"It went well at the time. The furnace installation price included a 3 year service contract for my 2 ac units and 2 furnaces.  I have had 3 maintainance  services so far which were ok.  Now they seem to have gone out of business for the last 4 months.  I am still due 3 more included  maintainance  service calls.   Are they coming back in business or am I out the money and hire someone else?"

"I recently had a new Carrier A/C Conditioner and air handler installed by Moe, one of the owners of Cross County. Moe could not have been more helpful in discussing what was wrong with my current system, what had to be replaced, how much it will cost, and when he could do it. He came on the day and time he promised with one of his associates and completed the installation in one day as promised. If you are having issues with your A/C system, I recommend calling Moe and at least getting a quote form him before deciding what you will do."

"It Went Very Well!!  They were very helpful.  The window in my apartment is located in an alcove in my studio apartment which makes it very complicated.  They lead me in the right direction. Installed an awesome unit!!  Would definitely use them again and recommend them highly!!!!!!!

"My landlord recently arranged for my Mitsubishi HVAC system to be cleaned, hiring Green Ductors Air Duct and Dryer Vent Cleaning. To be honest my expectations were low, but to my surprise the engineer, Alex, who conducted this work brought with him the kind of old-fashioned workmanship we once had in this country when a certain generation of Europeans were of working age. Alex spent no less than six hours cleaning every inch of a three-thermostat system. To make things better, he left the areas where he had worked in the apartment immaculate. During this lengthy time, Alex was highly professional, personable, and considerate of me and my space. I see that the Company has over 250 5-star reviews, so there is little more I can say – except that as a very tough NYC costumer, I offer up my highest recommendation for this business. The following day, I took the time to call the Owner, Dimitri, who could not have been more delighted by the fact that I had such a positive experience. This is a rare first-rate organization and you simply cannot go wrong when you need this type of work undertaken."

FAQs for swamp cooler installation and replacement projects in East Hanover, NJ

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.
