What winter actually asks of a system in Merrimac

143 nights below freezing, in an average year

Merrimac drops below freezing on about 143 nights a year, and below 10°F on about 21 of them. Those coldest nights — not the average winter day — are what a furnace, boiler or heat pump has to be sized for. A system that keeps up in November and struggles in January is usually a sizing problem, not a broken one.

Merrimac systems & permits

Merrimac's heat splits three ways in a manner that decides the whole conversation: about 61% of occupied homes on utility gas from National Grid, 20.5% on fuel oil or kerosene, and 7.6% on bottled propane — close to three in ten households on delivered fuel. The town's own light department states the consequence in plain language: if your gas is National Grid you can use Mass Save for audits, insulation and air source heat pumps, and 'if you are on propane, electric or oil, unfortunately you do not qualify for Mass Save programs.' That single sentence sets the economics of most heating replacements in this town.

Spencer Home Services air conditioning - heating furnace repair services — Boiler service in a residential basement.

Of 2,815 occupied Merrimac housing units, 61.0% heat with utility gas, 20.5% with fuel oil or kerosene, 9.8% with electricity and 7.6% with bottled or tank propane (ACS 2020-2024 5-year, table B25040).

Merrimac Municipal Light Department states that Mass Save is funded by National Grid, Eversource and Unitil, that National Grid natural gas customers in Merrimac do qualify, and that 'if you are on propane, electric or oil, unfortunately you do not qualify for Mass Save programs.'

MMLD has partnered with HomeWorks Energy to route residents with natural gas heat into the Mass Save programme, and separately expanded a no-cost energy assessment offer to fifty homes that use oil and propane.

Merrimac has accepted only online permit applications since November 29, 2016 — paper applications for residential and commercial building, electrical, plumbing and gas, mechanical and sprinkler permits are no longer accepted.

I needed a sewer line replaced on my property in Lowell. The issue was a complicated one but Will came out to assess the problem and gave me a fair price (much cheaper than another company!). Then the team of Oscar, Bryan, Paul, Julio, Cesar, and others came out and banged out the job in one (long) day. They crushed it. Highly recommend.

We found a 75 year old sewer pipe starting to leak and crack at the joints. Spencer Home Services was extremely helpful in giving an estimate and getting it repaired quickly by a skilled plumber!

Thanks so much to Jesse & the entire Spencer team! From my first interaction, I was kept up to date and given the best advice on how to move forward with a water leak. The service was professional, efficient, and a pleasure. I am a repeat customer and would gladly recommend Spencer Home Services to anyone. Thank you!

I Called Spencer yesterday with a sewer issue at my Clients home. They came out, assessed the job. Laid out all the options to the client. Had a price back in less than an hour. Client accepted the price, signed the contract, and the job was completed Today by 3:00. Professionals from the beginning and all the way through until the end.

I had an excellent experience with Spencer Home Services replacing my main water line — nearly 200 feet long! The crew worked efficiently and managed to finish everything within a single day, which was very impressive. The pricing was great, and the team went above and beyond with the cleanup and grading afterward — the yard looked neat and well-restored when they were done. Special thanks to Bryan Paul, Julio, Brian, Oscar, and Cesar for their professionalism, hard work, and attention to detail. I highly recommend Spencer Home Services for anyone looking for reliable and high-quality service! --------------- 7/16/26 Great company, actually stands by their warranty! Spencer Home Services put in a new main sewer line for me last August. Over the winter, the street patch settled a bit and started turning into a pothole. I called them up to see if they’d fix it under their warranty, and they were awesome about it. First, they sent someone out two weeks ago to run a camera down the whole pipe. They wanted to make sure the shifting dirt didn't cause any sagging or bellies underground, and they did the inspection with absolutely no pushback or extra fees. Once we confirmed the pipe was in perfect shape, they scheduled a crew to come back today to fix the road. They cut a clean square and put down a really solid, hot asphalt patch that's completely level with the street. It's rare to find a company that actually stands by their work and coordinates everything without a fight. Highly recommend them!

I had two projects done at my property. One was reline my sewer line and install a line for a basement half bathroom. The other was replacing my hot water storage tank. The worker quality was excellent, the only problem I had was finding the offices to pay off the work

I had 2 mini split systems installed in my townhome on the second and third floors. The work was done carefully and with good attention to details both outside and inside by Charles Barragan and John Sacharczyk. They provided thorough instruction with demonstrations on how to operate the systems with a remote regarding all modes, options etc . I am extremely pleased with the service from Spencer Home Service from estimate to completion. Charles and John provided  high quality work and were in a pleasure to work with.

We had our old cast iron/ceramic sewer pipe lined, and are very happy with the result! Oscar and Cesar were knowledgeable and friendly and were happy to show us what was going on as they were working on things. The quoting and scheduling process were straightforward too and everyone at Spencer home services was very responsive.

I couldn’t be more grateful for the team from Spencer who came out after Monday’s blizzard to complete our CIPP sewer line repair. Oscar, Cesar, Chuck, and Bryan (who plowed out the driveway) were outstanding from start to finish! They addressed a sewer line with multiple root intrusions that had been causing blockages, as well as a cavity in the old cast iron pipe that was allowing runoff to leak back through the foundation and into the house. The team thoroughly prepped the line by clearing the roots and descaling the pipe. Once done, they shot the new pipe in and cured it so that we have a single continuous sewer line pipe to the city main. They also removed the aging cast iron wye connection and replaced it with a new PVC fitting. Throughout the entire process, they were incredibly kind, patient, and professional. I asked a lot of questions, and they were happy to walk me through everything - from the materials being used, to how measurements are taken, how the resin is applied, and how the curing process works. I truly appreciated the education and transparency. I now have a much better understanding of my home’s sewer system and the work that was done. They were also very respectful of our home, keeping the work areas clean and carefully protecting our light-colored carpet with drop cloths. After the work was done, they cleaned up everything and it was almost like they weren't here at all. They treated our home like it was their own. Also, thank you as well to Rich, who came out on Saturday to assess the situation and scope the line, and to Angel and the front office staff who answered my questions over the weekend on timing for the job and if a plow would be possible. Every person I spoke with was friendly, responsive, and understanding. An exceptional team and an excellent experience all around - highly recommend!
