How to Hire a Home Repair Pro in Greater Boston in 2027
Quick answer
Before you call anyone, do four things: document the problem, confirm what the estimate covers, check credentials where the work needs them, and agree on payment before work starts. In Massachusetts, plumbers and gas fitters are state-licensed, and a home improvement deposit can't exceed one-third of the contract price (or the cost of special-order materials, if higher).

Key takeaways
- Photograph the model and serial label, the whole unit, and the problem.
- Ask every pro to quote the same scope so quotes are comparable.
- Look up plumber and gas fitter licenses on the state's license check page.
- Massachusetts has no single HVAC license; ask which license covers your job.
- Agree on price, timing and payment method in writing before work starts.
Step 1: Document the issue
A pro can only price what they can see. Give them:
- The model and serial number. Look for a label inside the door, on the back panel, or on the side of the unit. Photograph it.
- Two or three photos. One wide shot of the unit, one close-up of the problem, one of the label.
- A short video if it's safe to film. Ten seconds of the noise, leak or error code beats a paragraph of description.
- A timeline. When it started, what changed, and what you've already tried.

Two quotes that look far apart often cover different work. Ask every pro the same questions, and get the answers in writing, even if it's a text.
- Is there a diagnostic or trip fee, and does it go toward the repair?
- Does the price include parts and labor?
- Are parts new, OEM, or aftermarket?
- What warranty comes with the parts and the labor?
- What happens if the first fix doesn't solve it?
Step 3: Check credentials where applicable
Massachusetts licenses some trades and not others, so check what your job actually needs.
- Plumbing and gas fitting. Plumbers and gas fitters are licensed by the state Board of State Examiners of Plumbers and Gas Fitters, and must show their license type and number on signs and ads. Look them up on the state's Check a license page.
- HVAC. Massachusetts has no single HVAC license. Depending on the job, the tech may need a gas fitter license (gas furnaces and boilers), a sheet metal license (ductwork), or a refrigeration license (larger systems). EPA 608 certification is required to handle refrigerant. Ask which license covers your job, then look it up.
- Appliance repair. Many appliance repairs don't need a state trade license. Connecting or moving a gas appliance's gas line is gas fitting, so that part needs a licensed plumber or gas fitter.
- Bigger home improvement work. For many residential improvement jobs over $1,000, Massachusetts requires a written contract and a registered Home Improvement Contractor. Ask for the registration number.
Step 4: Agree on payment terms before work starts
Settle three things before anyone picks up a tool: the total price, when you pay, and how. Under Massachusetts home improvement law, a deposit can't exceed one-third of the contract price, or the actual cost of special-order materials if that is higher. Be wary of anyone asking for most of the money up front, cash only.
Practical examples
These are hypothetical examples to show the steps in action.
- Appliance (hypothetical). Your dryer runs but won't heat. You photograph the label inside the door, film the drum turning, and note that the lint trap is clean. You ask two companies whether the diagnostic fee is credited toward the repair and whether the quote includes the part. Now the quotes are comparable.
- Plumbing (hypothetical). Water drips from the shutoff valve under the kitchen sink. You turn off the valve if it closes fully, put a bowl under it, and photograph the fitting and any water damage. You look up each plumber's license number before booking.
- HVAC (hypothetical). Your gas furnace runs but blows cold air. You note the thermostat setting, photograph the furnace label and any blinking light code, and confirm the filter isn't clogged. You ask the tech which license they hold for gas heating work.
