"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!"

"I have used this company before for plumbing repairs, and I have to agree with many of the reviews. They were prompt, professional and I thought they charged a reasonable fee. So when I decided to install a water softener in my home, I immediately thought of them and asked them for a price estimate. I was told that they charged $69. When I balked at that, they said they would waive the fee and send someone out. I thought that was really nice of them to do that and was looking forward to getting their estimate. I was going to supply the water softener myself, so all I needed was to have them install it. I am fairly handy around the house myself and I knew that this wasn't going to take much more than a hour or so of their time and a few parts. It was not a big job. I was absolutely floored when I go their estimate. They wanted $4,243 for installation only. I find it hard to believe that they would want so much money for so little. I truly felt like they were trying to rip me off. I found a licensed plumber on Angis's List who did the job for $600, which as about what I had estimated the job would cost. I was extremely disappointed in CM Heating's highly overpriced estimate for a simple job. It certainly didn't inspire confidence in the company. They have lost my business forever."

Heating oil services FAQs
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.
