"Expert Mechanical came and helped me in a stressful time. My leach field was improperly installed where it was only operating at 30% and it had to be replaced. After searching through many contractors we found Expert Mechanical LLC. Seth and his team installed a new leach system, french drain and redirected my gutter system. They did an outstanding job.

We are family owned and operated. Our number one focus is on quality craftsmanship. I have over 16 years of experience in home improvement. I’ve done everything from kitchens, bathrooms, decks, patios, painting, custom trim work and more. Thank you for your interest in our services. We hope to hear from you soon! visit our website at: http://www.gustavolojanogc.com

"Gustavo and his team were phenomenal. The scope of the project evolved a lot after starting yet Gustavo was extremely fair with the pricing and tried his best to stick to the original timeline. His ethics are unmatched and did not deviate at all from his original quote for the initial job. From the day he started, you could tell Gustavo's primary objective was to ensure 100% satisfaction when it comes to quality and value. There was a fair amount of structural work such as removing a load bearing wall and replacing it with a complicated support beam. The final result looked like the house was originally built like this. So from the structural elements all the way down to the bathroom tile grouting everything was done with expert precision. Was also amazed to see how tidy his crew kept the house and cleaned up every single day and didn't damage a thing during the 6m renovation. He even helped out with minor things around the house outside of the renovation project which he did with full care. Couldn't recommend Gustavo and his team more. Can never go wrong hiring a great person who gives 100% to deliver."

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.
