Hot Water Heat Is What This Company Was Built On
Residential Boiler Heating Systems and Hydronic Service
Middlesex County is boiler country. Radiators, baseboard and steam, in houses that were standing long before the equipment in their basements showed up. Ricky came up on those systems. He spent roughly 20 years in the trade, most of it union work on the older housing around Boston.
Opus works on gas and electric boilers. Both fuels, all the common brands, install through annual service. We don’t do oil. If your boiler burns oil, we’re the wrong call and we’ll say so on the phone instead of after a truck is in your driveway.
A cast iron boiler can run 25 to 35 years if it gets looked at once a year. That’s the whole argument for service.
Boiler Installation and Boiler Repair
What Each Boiler Service Covers
Gas and electric boilers, sized to the house’s actual heat loss rather than matched to whatever was there before. Combi and high-efficiency options where the venting allows it. The permit, the inspection and hauling the old unit out are inside the quoted number.
Annual service, no-heat calls, leaks, noise and cold zones. Steam systems included, which is the part most local crews pass on. We’ll tell you when a repair is better money than a replacement.
What's Your Boiler Actually Doing?
No Heat, Noise, Leaks and Cold Radiators
Don’t wait until morning. Pipes start to matter after a few hours. Call 24/7 emergency help.
Usually air in the loop or a zone valve that stopped opening. That’s boiler repair, and it’s often a short visit.
Trapped air, low water, or on a steam system, condensate sitting where it shouldn’t. Worth booking annual boiler service before it gets louder.
Water on the floor under the unit
An old boiler short-cycling is burning money every hour. Worth pricing a boiler replacement against another winter of repairs.
We bleed the upstairs radiators before we pack up. That’s where the air ends up, and it’s the call we’d otherwise be back for in two weeks.
We Pipe the Gas, Too
Gas Line Installation and Licensed Gas Fitting
A boiler is only as good as the gas feeding it. Opus runs a new gas line and repairs existing lines, under the same license that pulls the permit.
We run a new gas line for a boiler, a stove, a dryer, a grill or a standby generator. We repair and leak-test what’s already in the walls. And when an appliance comes out, we cap the line off properly rather than leaving it live.
Add a high-efficiency boiler and a tankless unit to a house that was piped for one appliance, and the existing line often can’t carry both. We run the BTU math before we quote, not after the equipment is already sitting in your cellar. If the main needs upsizing, that’s in the written number from the start.
Gas fitting is licensed work in Massachusetts for a reason. It gets permitted and inspected like everything else.
Steam Is the One Most Crews Skip
Gas, Electric, Steam and High-Efficiency Boiler Systems
Gas boilers
Electric boilers
Steam systems
High-efficiency and combi
One thing worth hearing before you shop. A lower bid on a boiler usually means the near-boiler piping isn’t in it, and that piping is what decides whether the system runs quiet and lasts. It’s the first thing we look at on a system somebody else installed.
Before You Book a Boiler Visit
Common Questions About Heating and Boiler Services
- Do you work on steam boilers?
Yes, one pipe and two pipes both. Steam is common in the older housing around here and plenty of local techs won't service it, so this is work we actively take. If yours is banging, short-cycling or leaving upstairs rooms cold, that's usually fixable without replacing the system.
- Do you service oil boilers?
No. Opus works on gas and electricity only. It's an honest limit rather than a technicality, and we'd rather tell you on the phone than send someone who can't help. If you're thinking about moving off oil, the gas side of that conversion is work we do.
- Should I get a gas or an electric boiler?
If natural gas is already at the house, gas is usually the cheaper fuel to run here. Electric makes sense where there's no gas service, where venting would be difficult, or in a smaller space. We look at what's already at the street and what the house needs before recommending either.
- How long does a boiler last, and when does repair stop making sense?
A cast iron boiler often runs 25 to 35 years with annual service, and a high-efficiency unit closer to 15 to 20. The rough line: once a repair costs more than about a third of a new install and the unit is past 20, replacement is usually the better spend. We'll give you both numbers and let you decide.
- Can you run a new gas line for a stove, dryer or generator?
Yes. Gas fitting runs under the same license, so new line, repairs and leak checks are all handled in house. The permit and inspection are priced into the quote.
The Boiler Standard
Why Boiler Work Is the Job We Take First
A lot of crews would rather pull your boiler out and sell you a new one than actually work on it, and plenty won’t touch steam at all. Boilers are our first call, not our last. Rick services, repairs and replaces them himself, steam systems included, from a cold radiator in November to a full swap in January. When yours still has years left in it, you’ll hear that instead of a quote. He spent close to 20 years on New England systems, most of it union, working the same houses these boilers are sitting in today.

“Had a leak in my water heater tank. Ricky and team arrived very quickly, same day to assess the situation. I asked if we could avoid swapping out the water heater and just buy the parts needed to fix (I was being cheap!) – he did he absolute best (a few hours) trying to extract the old part and replace it with a new one. He tried far longer than any other plumber would have tried. After several hours of attempts we all came to the conclusion that it simply wasn’t coming out. I ran to Home Depot (it was Saturday) and grabbed a water heater. Ricky and team had it installed within 15 minutes and my new unit is working perfectly.
Very impressed with Ricky’s transparency and honesty. Most others wouldnt have given me the time of day…”
