"CandK was focused and diligent. They are based in Ames where I live. They were punctual and available when I had questions. I was offered a free Carrier Wi-Fi thermostat. I accepted. Installation issues with the powered "C" wire made me switch to a different thermostat. They handled all paperwork needed for rebates, and for a tax credit for the 2016 return. They have decades of experience. They know installation, and I chose them because I trust they will be in business for the life of my Carrier furnace and air-conditioner. The Dynamic air filter is the best filter I have ever seen in a residence. I just spoke with them today about also installing a new Rheem gas water tank to replace my existing tank."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.
