Ballard Natural gas did a great job of replacing our Old Oil Furnace with a All electric Solution - A Electric Heatpump & Air handler. Pete took the time to explain all the pros and cons and offered multiple options. They even suggested going through CPW- Community Power Works - which is a an amazing service from Seattle City light where they come in and do a thorough analysis of the house to suggest a solution. Pete & Niel came in to go over the setup which will work for me. Even though CPW suggested going all electric & Pete & Neil Suggested All electric, I was quite skeptical cause I thought that nothing can compare to GAS or OIL heat. I have a GAS hookup but still decided to take the advise from Ballard & CPW. After a month of using the new system - I must say that I am impressed. It is amazing to see such a quite system working all electric and giving me the same (If not better comfort) from the Oil heater. Thanks to Pete for being extra patient while I was bombarding him with 10s of questions. The job was very well done by Matt and he took care in ensuring that he gave me maximum space by changing and customizing the venting. Great job! Pros Very patient and knowledgeable sales staff. Thank you Pete They are not pushy. They give you all the information for you to make the decision They help you every step of the way - before to decide, After to get rebates & all the benefits from CPW Quality installation including the venting & other adds Cons None. I will highly recommend Ballard if you are thinking of upgrading your HVAC System "},"url":"https://www.angi.com/companylist/us/wa/lynnwood/ballard-natural-gas-service-inc-reviews-159974.htm"},"position":2},{"@type":"ListItem","item":{"@type":"LocalBusiness","name":"Hunt's Services","address":{"@type":"PostalAddress","addressRegion":"WA","addressCountry":"US"},"review":{"@type":"Review","author":{"@type":"Person","name":"Larry H."},"reviewBody":"I bought the deal and then they said they don’t service oil heaters.

Great initial response but had to wait a couple days for installation due to not having slimmer size heater in stock. Was more expensive than quoted but not by much. Overall I was quite satisfied. I have used these guys before and they are consistent performers.

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

"Avoid working with DVAC at all costs. When I initially requested a quote for the installation, I specifically asked for a 3-ton high-efficiency heat pump. Unfortunately, the experience with DVAC has been nothing short of frustrating. They began by stating that extensive work needed to be done, charging for it all upfront. However, when it came time to install, they drastically lowered the quality of the equipment, gaslighted me, and lied about what was being provided. Hidden charges surfaced right after my existing system was removed. The issues I discovered included but not limited to: 1.The installed heat pump is only 2-ton heat pump instead of the required 3-ton heat pump stated in the estimate. 2.The furnace provided is of lower quality than what was agreed upon. 3.The ducts installed are too small for the system. 4.The electrical cable used may be undersized for 3-ton heat pump. 5. All works were unpermitted. Throughout the project, I repeatedly verified the permit status with DVAC, including on the installation day (8/15). They assured me everything was in order. However, on 8/20, I confirmed with the City of Kirkland that none of the work had been permitted—a clear violation of both city regulations and our contract. Given these serious issues, I requested a full refund and the removal of all unpermitted work. DVAC refused to comply with the contract and denied the refund. If there were a zero-star option, I wouldn't even give them a single star."

"The install was supposed to be complete in 2 days. It took 7 and we were left without heat in October for 6 of them. The install was defective - pipes weren't attached and we were heating the crawl space for over a month before my husband identified the problem. We purchased on the premise that the system was eligible for a $4000.00 rebate thru PSE. When paperwork was sent to me to fill out, it qualified for $2400.00."

FAQs for heating oil service projects in Duvall, WA
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.
