 Trustindex verifies that the original source of the review is Google. My maintenance checkup was done on time as scheduled. George was extremely thorough, checking the system and was kind enough to look around as to why I had so much dust. He did find the problem, I believe!   Thank you for your respect of my home and my pets and your thorough checkup of both units, AC and heat systems.

He also checked on the flow of air to our second bedroom and every thing appeared to be working properly

Should I Switch from a Traditional Water Heater to A Tankless Water Heater?

To answer this question, it is best to look at the features and benefits of a tankless water heater, although being tired of waiting for your traditional water heater tank to refill may be enough of a reason to make the change.

Tankless water heaters use copper heat exchangers to heat water in real time and consume much less energy than traditional tanks. Reducing your energy consumption leads to lower utility costs and equates to saving you money.
There are energy efficiency rebates and tax credits available for making the switch. In addition to instant savings, installing a tankless water heater will also increase your home value.
