"Brian and Nicole did an amazing job on our house! We had a variety of plumbing issues and they made quick work of it. Their communication is top notch. Saved us a lot of money by showing us a better way. They were friendly and kept the job clean and safe. They installed a tankless water heater, PEX throughout the house, finished the bathroom plumbing and the plumbing for 2 kitchens. They helped dig out the old sewer / drain plumbing and installed all new pipes. Everything works as it should and we couldn't be happier! If you have plumbing needs these folks are the best!"

At Paschal there is a single statement that we live by every day. “Professional People. Professional Service.” Being a professional is more than just earning a living through an occupation. Professionalism involves consistently achieving high standards, both visibly and “behind the scenes” – whatever your role or profession. Professionalism is a powerful quality. It allows you to fulfill your role to the best of your ability. It helps you to impress and inspire others. And it gives you a deep sense of satisfaction and self-worth. What’s more, professionalism is something that everyone can aspire to from day one of their career. A Paschal Professional gives 150% every day. They go above and beyond what needs to be done. They have pride & satisfaction in every project they tackle.

"Installed my elderly grandmother Norma's HVAC 6 years ago. Recently A coil was icing up. She was told she'd need a new A coil (not cleaning first). A-Coil was covered under 10 year warranty but not labor. They quoted her 2900 to install the new A-Coil. I checked with multiple other HVAC firms, and the labor to install this part and the refridgerant was on the order of 900-1000. This firm gouged my elderly grandmother. They didn't send her an itemized bill, so I think they just have a set price that includes the part. They took her money and there has been no effort by them to make this right. Watch out, they'll do this to you too or someone you love. They said it's inflation, but this is what happens when they sense that they can take advantage of someone. They won't talk to me (her grandson), only her, and told her there was nothing they could do and just took her money. Beware, use someone else, you cannot trust these people."

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.
