67 Degrees Heating & Cooling

67 Degrees Heating & Cooling is a Lawrence-based HVAC shop built around one name: Rafael, the technician who shows up on almost every one of the company's 59 collected reviews, backed by an office staffer customers know as Mili (also spelled Milly or Milagros in different reviews) who fields the calls. Google puts the company at 5 stars across 57 ratings, and Angi and HomeAdvisor both show 4.9 from ten. What holds across five years of reviews, from 2022 through this July, is the emergency-response story: customers describe Rafael showing up the same day, sometimes within an hour, for a dead furnace in a freezing house, a water boiler that wouldn't stay lit, or an AC that quit during a heat wave. In a 2022 review, one customer said they'd called every heating company they could find with no luck before Rafael arrived within the hour and fixed it in minutes; another 2022 review about a stuck boiler says he came the same day it was called in. Reviewers across the years also credit him with real installation work, not just repairs: a four-head mini-split system done in two days, described in a 2024 review; a ducted central AC system with an attic-run air handler, also from 2024; two full furnace replacements with carbon monoxide sensors added at no extra ask, in a 2022 review; and a furnace swap one customer, in a 2022 review, called 'pure perfection' at a price well under competing quotes. The tone doesn't waver into 2026 either — four reviews in the last six months describe the same pattern: punctual, professional, walked-through explanations, and a clean site when the crew leaves. Several reviewers specifically call out Mili's scheduling and phone manner as part of what makes the company easy to work with. There isn't a documented complaint anywhere in the file, which stands out for a shop with this much volume — worth remembering this is Google, Angi and HomeAdvisor review text, not a state license or BBB record, so it doesn't confirm credentials on its own. For a mini-split install, a furnace swap, or an after-hours no-heat emergency in the Merrimack Valley, this is a company with a long, specific, and consistently positive paper trail behind it.
