"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"

"Juan is very professional and passionate about what he does. Even though we have an annoying HOA in our community that sets all kinds of rules, he communicated with the HOA ahead of time and showed up at the time we agreed. Despite the fact that the HOA failed to tell us the right way to the roof where AC units are located at the beginning, Juan was very patient and called HOA multiple times to figure things out. The repair was completed quickly and properly. I highly recommend Capella HVAC in San Jose."

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.
Increase energy efficiency by insulating your basement and attic.
Turn down your thermostat a few degrees.
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.
