We are a family owned business based in Worcester, MA with more than 50 employees. We are primarily a home heating oil delivery company but we own four gas stations as well. Our team of service technicians and plumbers are on hand 24/7 to service our customers heating, air conditioning and plumbing needs.

"Peterson delivered oil for only the second time to my house and the very next day my boiler stopped working. When a tech from another company came out he diagnosed it as bad oil which damaged the boiler due to the bad mixture causing the system to run sluggish and the primary control to shut down. I had no heat and water for several hours. When Peterson pumped out my tank what was in there can only be described as what looked like thick bacon grease. When I asked if they could come clean my tank the customer service agent came back and said her manager would not do that because I decided I was no longer getting oil from Peterson and went with another company. I spoke to the manager who was rude and did nothing to rectify this situation. Instead of receiving my full money back like I asked I was sent a bill for their tech who came out and changed a filter which was gummed up due to their oil. Imagine being asked to pay for a service caused by oil they delivered. Seems like a pretty good scam doesn't it? After calling numerous times to try and get my money back and being given several different responses I was finally paid back money I desperately needed. However, Peterson refused to give me a full payment back stating that their technicians pumped out less than a tank even though the new company came and filled my entire tank with fresh oil. Rather than continue to fight with this company I decided to go to the attorney general. You should too if you have had similar experiences. Hopefully the attorney general will finally step in. The state fined Peterson $450,000, but what about the consumers who have been negatively impacted by this company? They never gave me options for other oil until I complained. By the time I was told about biodiesel it was too late and I had to pay to have my boiler fixed. If research shows that Biodiesel is not good to use in cold temperatures why does Peterson think it is ok to put 40-80% in peoples tanks which is way over the recommended amount of 5-20%?"

"If I could give negative stars I would. Our furnace wasn’t working. They came and replaced a part that apparently made no sense to replace, charged obscene hourly rates and charged for commute time. Next day the furnace doesn’t work again they come and don’t charge and do another quick fix. Three days later the furnace breaks again and they say they fixed it but it’s still broken. A different company comes and says this furnace is 25 years old, needs to be replaced, several parts are broken and they replaced this piece with an old piece. He literally had to decommission the furnace according to his license before he left. So we are 540 bucks lighter with now the need for a new furnace. These guys are scammers and clearly don’t have a clue."

Heating Oil questions, answered by experts

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
