Jonasson Plumbing & Heating is a Needham institution — a family business Carl H. Jonasson Jr. incorporated in 1976, continuing three generations of Jonasson plumbers, with his son Travis, a Master Plumber, now working alongside him. The trade itself runs in the family: local news coverage during a widespread cold-weather plumbing crisis described Travis working around the clock between flooded houses, while Carl explained the company was prioritizing scheduling for its regular, established customers first. Several long-time clients back that reputation up directly — a 2023 review described trusting Carl and his staff with all their plumbing and heating needs for 15 years, calling them honest, fair and professional, and another said they'd used the company for over 20 years. A 2025 review named Carl, Travis and long-term employee Walter specifically, crediting them with fixing an inconsistent water-temperature problem and standing behind their work when something needs a second look. A trade publication also featured the company's technicians for correctly tracing a high-efficiency boiler's repeated lockouts to sludgy, muddy water flow — the kind of diagnostic detail that points to real expertise. There's a serious complaint on the other side of the ledger, though. A 2026 review said the rate charged to fix a leaking toilet was more than the cost of installing a new one, roughly double what competitors quote, and described the owner as abrasive and unresponsive during the dispute. A near-identical complaint about rates running about double competitors' also appears on the company's Better Business Bureau profile — which may be the same account showing up in two places rather than two separate customers, but either way it's a real, pointed concern about pricing and how a dispute gets handled. For routine plumbing and heating work, especially if you're already an established customer, the decades of specific, positive accounts here carry real weight; for a one-off repair, it's worth getting a firm price up front given the pricing complaint on record, and knowing that a disagreement over cost might not go smoothly.
“Technicians with Jonasson Plumbing and Heating of Needham, Massachusetts noticed several lockouts on a Laars HT1.330 Mascot high-efficiency boiler system from poor flow and high temperatures, discovering that the water was very muddy and sludgy.”
“Carl Jonasson, owner of C.H. Jonasson Corp., a Needham-based plumbing, heating, and air conditioning contractor, said he’s prioritizing regular customers, who can probably get a repair scheduled within a couple of days.”
“Plumber Travis Jonasson has spent the last 48 hours or so jumping from soggy house to soggy house as his phone buzzes away on his belt with calls he doesn't really have time to answer.”
“Travis Jonasson, a fourth-generation professional plumber, works with his father Carl, who has run Jonasson Plumbing since its founding a half-century ago in 1976.”
Responsive, kind, efficient
Mr. Jonasson's rates were nearly double his competition. He charged more to fix a leaking toilet than the actual installation. He is also one of the most abrasive, combative, unresponsivess, obnoxious businesspeople I have ever encountered. I made the big mistake of reading his Google reviews which clearly were plants instead of those on other review sites. My advice? Search carefully, scroll down to the legitimate critical reviews and find one of genuinely well reviewed, civil, competitively priced alternatives.
Have been using them for over 20 plus years. Honest and knowledgeable.
Carl Jonasson, his sonTravis and long term employee Walter have provided is incredible heating, a/c, and plumbing services for many many years. Everything holds up and if there is a problem, they make it right. Walter just fixed our inconsistent water temperatures in our new home and did so with care and talent. All 3 men are polite, professional, talented, and dedicated. Replies for service are always prompt! We are so grateful!!!
