"Elliot was kind, courteous, professional and extraordinarily helpful. In his initial visit he looked at the damage, and the surrounding area, and provided me with multiple options to correct the problem. He had researched Reverse Osmosis systems, and discussed a newer product that was infinately superior to my current system. He recommended updates to piping as I have an older home, and some older installations did not meet current code requirements. I found Eliot to me very knowledgable, prompt and trustworthy....I Highly recommend him!!!!"

"We called late on a Saturday not sure what the problem with our toilet was beyond the classic “it won’t flush the water down.” Tamara was able to walk me through the troubleshooting process to determine if they were the right company to help me, in other words was my issue drain related or more of a toilet hardware/plumbing issue. Once we determined it was the drain she was able to give me an estimate and get someone to come out. Less than an hour later the technician called to let me know he was on the way. Once he arrived he did some more troubleshooting and quickly determined what was causing the issue and resolved it. There was no mess, in fact he left the bathroom cleaner than he found it. Total cost came in under the estimate and now my toilet works better than it ever has. Thank you Ecoclean for your prompt and professional service."

"Christian was instrumental in the building of our home.

He would arrive to work early each day and stay late when necessary to complete various aspects of the job...always with a smile and a positive attitude. Needless to say his work ethic is exceptional. His attention to detail and ability to problem solve on the fly as issues came up (they always do ) are exemplary.

"Total Ripoff! My boiler stopped working the other day and my usual company was unable to come out due to being short-staffed that day. I resorted to google and unfortunately came across Aire Serv. Their technician (who was very nice) came out to assess the situation and determined it was caused by a damaged pilot assembly. After calling around for replacement parts, I was told that the parts were out of stock until later in the week. Despite this, I was still charged $234 for the trip fee and diagnostic fee. I was then quoted $1112 for the repairs to be done once the parts were in. I shared this quote with my normal company and they were appalled! Thankfully they fixed the issue for less than half the price Aire Serv was going to charge me! PLEASE do not use this money-grubbing company, and instead use a local independent company if you need heating work done!"

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
