"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."

"We called Machen for an estimate to tear off our old roof on our house and detached garage. They were very responsive and Jodi even came out on a Saturday to give us an estimate. He was very knowledgeable regarding the materials and products we needed, and we were impressed that he actually climbed the roof to take all of the measurements, where other contractors we had contacted did not. The estimate we received was fair considering that the roof deck would need wrapped and the amount of ice guard we needed. Jodi and his team were on time every day and got right to work. They took their time on the job and were very conscientious about the work performed to ensure it was done correctly. Jodi takes a lot of pride in ensuring the job site remains neat and takes a lot of care to ensure they thoroughly clean up before leaving for the day. We ran into heavy rain halfway through the project and Jodi even came out on the weekend to ensure that the roof was water tight before the rain hit. The new roof looks great and we are very pleased with the end result!"

Water Heaters FAQs, answered by experts

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

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.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.
