Occasionally, over the years, the heater has stopped working. Several times, Annuzzi Heating and Cooling has been able to breathe new life into it. (Their competition, other companies, have given me the hard sell to buy a new heater [ex: a technician from The Competition (not Annuzzi's] never did identify the problem, and was reluctant to call the manufacturer for guidance in identifying the problem/ordering new parts.) The Annuzzi technician figured out what the problem was--a corroded battery in the thermostat, and when he replaced it, the heater worked! What would you rather pay for, a new battery, or a new heater? So yes, I'm a big fan of Annuzzi's, and when we order our new heater, you BET it will be from Annuzzi's! I recommend them high;y!

This rating is from the Order of Malta in Menlo Park. Our heater went down, and we called these guys to come out. Not only did they take care of us right away, and solve our problem, they even had a tech named Chance, who stopped by on his own, to see how the heater was working. THAT customer...
First person who came said that he couldn’t do it on his own. Harris Water Heaters were sent out next. The work was done the following day. He was very professional, skilled and punctual. What more can you ask for?

Very prompt! Called them in the morning and they installed the new water heater by the afternoon. They took away the old broken water heater. The whole job took less than two hours.
The technician was very nice, he fixed the heater that was broken. I also needed to have another heater replaced and he was supposed to give us a call back after he found some pricing and never called us back.

FAQs for heating oil service projects in San Lorenzo, CA
To buy heating oil for your house, contact local heating oil companies to compare prices and place an order once you decide on a supplier. The company will have to deliver your heating oil in a truck designed to carry and dispense heating oil safely. Call and order your heating oil early enough to have your oil delivered before you need to start using it for home heating.
On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.
You save money on heating oil in a few ways:
Make sure your home is well insulated and sealed against drafts and heat leakage.
Use a thermostat that’s working properly and calibrated accurately.
Program your thermostat to lower the heat when you’re not home.
Order heating oil during the off-season when prices are likely to be lower.
Summer months tend to be when heating oil prices are lowest because of decreased demand. Buying heating oil during the off-season also prepares you for when the weather gets cold, and you need to start using the oil to heat your home. Although heating oil prices will fluctuate, it’s best to avoid purchasing between September and April, as that's the peak season for heating oil demand.
Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
