He was coming to clean my furnace which sadly was way overdue and the primary went the night before his service call. Diagnosed the problem right away, gave me a fair price and fixed the problem and cleaned the furnace in little more than an hour. Thumbs up to Muller Oil!!!!

Great Service and awesome prices.




Miller Oil just installed a new furnace in my home. They were very professionals, polite and answered all my question that I had.


Emergency Furnace Replacement




My furnace died in my new house in early December, no less. Every employee I interacted with was professional and courteous. Doug procured a furnace for me within days and the techs had it installed within the week. Miller Oil dropped off space heaters for us to use in the interim to prevent the pipes from freezing and keep us comfortable. Russ, Alex and the 3rd tech (my apologies, I don't know your name) were efficient and patiently explained the system to me. Thanks to every one at Miller Oil!


Fast efficient service




I called in the morning for service and he came out that afternoon. Fixed the problem on the spot.


Superior and Courteous Service




I contacted Miller Oil Co. Monday morning at 8:00am because our oil furnace was leaking water and we had no hot water. Russ arrived within the hour and quickly diagnosed the problem and replaced the necessary parts to get our system operational again.


Great Service




We can always depend on Miller Oil's prompt response,and great service technicians. They are Informative, professional, and cordial.
