Gemini's Heating and Cooling

Gemini's Heating and Cooling has built a presence in Lowell, Massachusetts under the direction of owner-operator Hiram Lopez, who personally performs installations for residential customers across the city and surrounding Middlesex County. The contractor holds a 4.7-star average from 92 reviews on the directory, a rating that reflects a polarized but engaged customer base. Albert Holguin, who shared a scathing January 2025 account of installation failures and a planned small-claims filing, contrasts sharply with Shrish Budree, who hired the company for a full home heat-pump system spanning two floors and praised Hiram's reliability and honesty throughout the project. This pattern of individualized, owner-performed work means every job lands on the same pair of hands, for better or worse depending on project scope.

The company's service menu centers on whole-home heat-pump solutions, a fitting specialty for Lowell's variable New England climate that demands both efficient winter heating and summer cooling. Shrish Budree's review describes a multi-unit installation featuring two heat-pump condensers, an air handler with new ducting to all second-floor rooms, and four wall-mounted mini-split units for the first floor, a configuration that positions the contractor as a full-home retrofit specialist rather than a quick-repair truck operation. Whether Gemini's Heating and Cooling manages permitting, coordinates electrical upgrades, or offers post-installation maintenance checks is not confirmed in available documentation, so homeowners should confirm these details directly before signing a contract.

Hiram Lopez appears by name in both a positive and a negative review, making him the clearest point of contact and the primary variable in customer outcomes. Shrish Budree credits Hiram with managing a substantial setback during his multi-unit installation, including a thermostat calibration issue that initially left the ducted system unable to heat properly, a problem Hiram eventually resolved after troubleshooting. Albert Holguin, however, describes a very different experience: an exhaust pipe installed without glue around the seal, a condensation pump added to a system that never had one, and a return-air box cut without explanation, followed by a second leak that Hiram attributed to the missing glue. Hiram responded to the emergency call but did not offer proactive follow-up after the repair, a gap that left Albert footing a $3,000 corrective bill.
