They put together a full package with several line item choices, handled the removal of the old system and oil tank, and installed the new system professionally. The system works well and saves money over the old oil unit. However, the house had low humidity so then we had them add a humidifier. The first humidifier had issues, and the next didn't keep the humidity in the house up high enough. They were very professional and fixed/replaced the humidifiers multiple times without charging more money until we were finally satisfied that it was working properly and sufficient for our house. Supreme Air has been very helpful and professional, and now the temperature and humidity in our house is probably as comfortable as we can get it.

They are a large company, I don't know which branch services me. They deliver here, I never went there. It was the heating fees in 2014- 2015, so it included this year. Per gallon, they overcharged me. They suggested very strongly that I purchase a fixed price contract, and then of course the oil prices went down but if they hadn't encouraged me so much to get a fixed price contract, I wouldn't have gotten a fixed price contract. I could have benefited from the oil prices going down. One of the things they did, their price per gallon, is higher than other companies so I should have gone with a different company. I am this year. I wouldn't use them again. I didn't run out of oil all of last season so that is good.

I've owned 3 old homes over the last 28 years. This was my best experience - ever - with any contractor.
When you hire All Steamed Up to work on your heating system, you get partners Frank and Gordon - they have no other employees. These guys have a wealth of knowledge gained from decades of hands-on experience at troubleshooting, repairing and replacing heating systems, which is more relevant to me (as a homeowner) than mixing in time spent running a large business.
Both Frank and Gordon are thorough, thoughtful, honest, conscientious, resourceful, funny, courteous, knowledgeable and humble - and they're perfectionists about their customers' systems. I could add to that list, but they're simply great people and just the kind of folks you want to work on your home.
Also, they?re not out to pump up the price of a contract by installing components you don't really need. They're interested in getting your heating system working properly at minimal cost. I got estimates from 5 companies. 4 of them proposed brand new boilers, but not Frank. He took one look at my 9-year-old Columbia boiler and told me I didn't need to replace it because it was still a current model - that he could simply swap out the oil burner with a new gas burner.
Frank's honesty and knowledge saved me $2,600 to $4,300 compared to the other estimates. Plus, the price included a new interior 25? gas supply pipe that the other estimates didn?t. And Gordon's valve upgrades are top-notch, maximizing system flexibility and minimizing future service costs.
Frank and Gordon gave me value, quality and the peace of mind that comes from knowing my heating system is in the best hands out there.

We have a maintenance contract with them. We have an inside tank and there is an access point to the outside. We've been with them for a long time. They do a calculation based on our usage and the weather as to when the oil is getting low and schedule automatic deliveries.

"we had a Bosch boiler hot water combo system installed in the spring of last year for $9500. We used the heating system on some cool days and nights, so it seemed to do the job of heating our home. This year is the first time we have used it for the entire winter. If the temperatures are mild the system works okay. If the temperature drops below 30 degrees it will not heat our home. We were able to keep the house warm thanks to our pellet stove. In Hine sight, We wish we would have stayed with the conventional boiler system for about half of what we paid for this inadequate system. buyers know what you are getting into before you buy."

FAQs for heating oil service projects in Gwynn Oak, MD
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.
