"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

Additional DBA - JCF Inc .

"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

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.
