Frequently Asked Questions

Tankless water heaters provide a variety of benefits, including on-demand hot water, energy savings, space savings, and long-term cost savings. Tankless water heaters offer an unlimited supply of hot water since they don’t rely on a storage tank like traditional models. Additionally, because they only heat water when it is needed, they are more efficient than traditional models and can save up to 30% in energy costs each year. Furthermore, tankless models take up far less space than traditional models since they don’t require a large storage tank. Lastly, because tankless water heaters last longer than traditional models (typically 20 years or more), they can provide significant cost savings in the long run.
Before having a tankless water heater installed, it is important to consider the size and power requirements of your home. Tankless water heaters require more power than traditional models as they need to heat water on demand. Additionally, you should determine what type of fuel source you will use for your tankless system – either natural gas or electricity – as this will affect the overall cost of installation and operation. Finally, it is important to find a qualified contractor who specializes in tankless water heater installations since these systems require specialized knowledge for proper installation and maintenance.
The time it takes to install a tankless water heater can vary depending on the complexity of the project and the scope of work being done. However, most installations take between one and two days from start to finish. During this time, contractors will assess the existing plumbing infrastructure, determine what type of fuel source is needed for the installation, mount the new unit in place, test all connections for leaks, and make any necessary adjustments. Once complete, your contractor can provide you with an overview of how to operate and maintain your new system.
Before having a tankless water heater installed, you should make sure that your home is equipped with the proper gas or electric line capacity for the size of the heater you’re installing. You’ll also need to check local codes and regulations to ensure that your installation meets all safety requirements. Additionally, it’s important that you have a qualified plumber inspect and install your new tankless water heater, as only properly trained professionals can guarantee safe and effective operation.
Regular maintenance is an essential part of keeping your tankless water heater running efficiently and safely. This includes flushing the unit every 6-12 months with a cleaning solution, checking all electrical connections regularly, inspecting pipes and vents monthly, replacing filters as needed, and cleaning up sediment buildup around the heating elements. Additionally, you should also have your tankless water heater inspected annually by a qualified technician in order to ensure that it’s running properly and safely.
Tankless water heaters often have a higher upfront cost compared to traditional storage tank models, but they also offer many advantages that can help you save money in the long run. Tankless units don’t require as much energy to keep hot water stored in a tank, so you can expect lower monthly energy bills. Additionally, because these units have a longer lifespan, you won’t have to replace them as often, which helps reduce the overall cost of ownership.
Most manufacturers offer a limited warranty on their tankless water heaters, which generally covers parts and labor up to 5 years. It’s important to read the fine print in your product’s warranty agreement to understand what is and isn’t covered before you purchase a tankless water heater. Additionally, most warranties also require regular maintenance in order for them to remain valid.
Yes! Before starting your installation project, it’s important to make sure that you have all the necessary materials and tools ready ahead of time. Additionally, it’s important to review the manufacturer’s installation guidelines carefully and follow them step-by-step. Finally, make sure that you have a qualified plumber inspect your tankless water heater after installation in order to ensure safe and efficient operation.
Yes. If you’re considering installing your tankless water heater outdoors, it’s important to ensure that all components are properly sealed and insulated against the elements in order to prevent corrosion and other damage. Additionally, you should consult with a qualified technician or manufacturer to make sure that the specific model of tankless heater you have is suitable for outdoor installation. Finally, it’s also important to note that most warranties will not cover any issues caused by improper installation or exposure to certain weather conditions.
If you live in an area with extreme cold weather, it’s important to take extra steps to protect your tankless water heater. This includes installing a freeze protection system, which will detect when temperatures drop below a certain point and automatically turn on the unit so that it can warm up and prevent damage. Additionally, you should also make sure that all pipes and vents leading into and out of the unit are properly insulated against cold temperatures. Finally, if you plan on being away from home for extended periods of time during cold weather months, make sure to have someone check on your water heater regularly.

We’ve already been a long time customer with Cole Services for our air-conditioning. Today I had the pleasure of working with Drazen and Jacob for replacing our water heater for my parents home. The process was very smooth. It was installed all in the same day, clean, and it was quick. They explained each step of the way and made things very easy for us. I also appreciated Oscar, who helped us with financing. 10/10.
I’d recommend working with them again.

Nick G. & Edgar arrived for my regular HVAC maintenance. As always, they were prompt and I received a call ahead of the scheduled service. They were respectful of my home, were thorough and explained everything in detail. There was no bait & switch as some companies do and I felt great with their services and care. I have been using Cole for many years and would give them my highest recommendations.

Nick and Cody came out. They were prompt and friendly. Found the problem quickly, made the repair and we're done in less than an hour. Professional and worked well together. Pleasant to work with. We've been with Cole's for many years now. This was the best experience yet. Way to go guys! We told Nick he was St. Nick because of the time of the year and how easy it was.

I have been a customer of Cole Services since 2011 when they were able to help me replace my ancient furnace during a very cold December when mine quit. I have continued using them for annual tune ups of that system, and I've also called them in for various plumbing jobs. They've always been super friendly and helpful, and efficient too. They are also up front about costs and good with providing options. Nick was my service technician today, and he was great. I look forward to working with him in the future. I highly recommend Cole Services for your heating/cooling and plumbing needs!
