Frequently Asked Questions

Tankless water heaters work similarly to traditional water heaters, but instead of storing the heated water in a storage tank, hot water is produced on-demand as you need it. By heating your water on-demand, tankless water heaters provide your home with a constant and almost unlimited amount of hot water.

Tankless water heaters require regular maintenance, similar to your furnace or air conditioning unit. Annual maintenance is the best way to make sure your tankless water heater is working efficiently and it’s also an opportunity to flush your system. Flushing your system removes any sediment or mineral buildup that happens over time.

Every home can benefit from a tankless water heater, especially those without the space for water storage tanks. Tankless water heaters require less space and have the additional benefit of energy savings as they only heat water when you need it. Tankless units can also last longer and keep your water cleaner.

How long installation takes will differ depending on your home, but you can expect most installations to take 3 to 5 hours. Installation can be influenced by whether we are replacing a tankless water heater or a traditional unit. The location of your water heater inside your home can also influence how long installation might take.

You can prepare your home for installation by removing any unnecessary items from our workspaces. For tankless water heater installation, this includes emptying out your furnace room of any clutter and clearing a path through your home. By doing this, you’ll help us install your new water heater efficiently and safely.

Our Guarantees

We stand behind our work, whether you’re getting a new furnace or we’re doing a routine vent cleaning. We aren’t happy until you’re happy, and we will do everything we can to make your installation or repair experience a great one.

Why Choose Us?


No Loopholes™

We aren’t satisfied until you are completely satisfied with our craftsmanship, products, and materials. If you are not completely satisfied with our service, our people, or the quality and performance of your home comfort system within two years from the installation date, and there is nothing we can do to make it right for you, then we will gladly remove the system and return your original investment.


No Hassles™

If your new system breaks down within the first year, leaving you without heating or cooling, we guarantee that we will repair your system within twenty-four hours of your call or we will fix your problem for free and give you $1,000 for the inconvenience.


Just Right™

Not too hot, not too cold… just right!™ We guarantee that any system we install in your home will either heat or cool your system to its engineered specifications for at least five years. We also guarantee a temperature variance of no greater than two degrees Celsius on your thermostat. If not, we will make any modifications up to and including replacing the entire system at no additional charge.


We Respect You™

We promise that while our technicians are in your home, they will respect your property and protect it from damage and leave their workspace as clean as they found it. You can always expect to be treated courteously and have your questions answered. If we fail to meet any of the high standards we have set for ourselves, we will give you our full Five Year System Check-Up Package free of charge.
