2016-2020 Super Service Winners! Owner Duane Carr has worked in the HVAC industry since graduating from Thaddeus Stevens State College of Technology in 1997. Duane started Prime Heating and Air Conditioning to provide Syracuse and the CNY Region with a local, independently owned HVAC company that earns the trust of its customers by doing quality work at reasonable prices. With Duane's commitment to family and community, he's built his business to include his two brothers, Neal and Eric, to provide outstanding service and local community support.

"I called and my timing must have been perfect. 2 technicians showed up 30 minutes later. They put on shoe covers which I appreciate. They opened up the unit and checked the flame and spark. That must have been enough since the unit started working. They checked to make sure the propane was flowing and cleaned the condensation pan. Within 30 minutes after arriving, they were done. I plan to have them come back in a couple of months to maintain the ductless splits for this summer. What they charge for the service is very reasonable given that I had contacted a competitor and received a quote that more than 2x what I paid."

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.
