## The honest read

Delta HVAC Services is a Norwood, MA outfit that's stuck to commercial heating and air conditioning work since it was founded in 2003, run by owner Mark Lynch out of a Pleasant Street shop for over two decades.

The company's own site describes maintenance contracts, system upgrades and replacements, and design/build HVAC construction — the kind of ongoing service agreements commercial clients rely on rather than one-off residential calls — plus round-the-clock service availability.

Its Better Business Bureau file carries an A+ grade, though the business has not sought formal BBB accreditation. On Google, it has only two ratings averaging 3 stars, too few to draw much from either way, and there's no written review history to point to for a read on typical outcomes.

Anyone considering Delta HVAC for a job would do well to ask for recent references directly, since most of what's public about them right now is what the company says about itself.

**Strengths:**
- BBB A+ rating — earned without seeking formal accreditation
- Two decades operating — in business in Norwood since 2003

**Concerns:**
- Thin Google presence — only 2 ratings, averaging 3 stars
