"Dave and AJ from Freedom Contracting & Excavating did a great job for a reasonable price. I had an idea for an outdoor griddle setup using natural gas instead of propane tanks. I thought it was a long shot but they were able to make it happen. Very courteous and straight forward. They even went above and beyond by helping me with the natural gas conversion on my griddle. I would definitely hire them again and if you need any gas line work done, call Freedom C & E for sure! Thanks again!"

STA SO COOL HVAC is your best choice for residential and commercial jobs. Gino has over 15 years in the industry. We have a very good and reliable supplier that we can provide additional purchase discounts for new unit installations that we always pass on to you the clients. Call us today for the best service for the best price. Many people ask me where I got the business name. My maternal grandfather and I were very close, his name was Steve Staso. I decided to separate his last name and add cool. Hence the name STA SO COOL came about. My grandfather meant the world to me and I plan on honoring his name with my HVAC business.

"This company was out last week installed a furnace at my mother's house did a great job but after they finished the job they did recommend so other things be replaced the hot water tank. This was very important since the flu was busted. So the next day mom decided to get a 50 gallon power vent and ac to the house as she had never had ac before. So gino the owner came out on Tuesday night took some measurements and his guys came out Saturday morning installed the power vent hot water tank and ac unit. They went above and beyond any company i have seen in the past. Thank you Gino Casey Joe for a fantastic job."

Reliant gas lines is a natural gas service line repair or replacement company. I handle the buried portion of the service line from curb stop to meter and the buried house line if the meter is far away from the house. I do a good job at a fair price, am qualified for both Peoples Gas and Columbia Gas and fully insured. As a small owner operator business I can be flexible on scheduling as these types of problems tend to be emergencies. While in business for myself just a short time now I have over 15 years of experience in the natural gas industry involving repair and replacement of gas mains and service lines.

"Reliant Gas Lines arrived at my house quickly. They made all the repairs fast and efficiently. Matt and his crew were very respectful of me and my property. I would not hesitate to hire them again. Very highly recommended."

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.
