Water heaters require maintenance. A water heater is used every day, yet we don't often think of it — until it goes out and we have no hot water or it leaks and causes damage. The buildup of sediment and scale from the water inside your water heater causes it to lose efficiency over the years and can cause premature tank failure. This can be addressed by flushing your water heater regularly. Today's water heaters are more efficient, safer, and create fewer pollutants, as manufacturing regulations have increased.

In 1932, Ernest V. Ongaro founded Ongaro Plumbing, with his first shop in Fairfax, California.

Heating repair and installation were added, and sons Donald, Ernest and Richard joined to help with the growing company. After 40 years in business, Ernest V. retired. The third generation has joined ever-growing Ongaro & Sons, starting with current President, Ernest J., grandson of Ernest V.

HVAC is the acronym for Heating, Ventilation, and Air Conditioning. We are all familiar with heating and air conditioning, but what is ventilation? Heating and air conditioning has to do with controlling the temperature within our home. Air filters and air cleaners clean the air within the home but what about bringing fresh air into your home? Ventilation is the process of bringing fresh air into the home. At certain times of the year we keep our house closed up tight, for example in the winter when it's cold outside, in the summer when it's hot outside, or in the spring when pollen and allergens are in the air.
