Who Repairs Multi-Unit HVAC Systems in Saint John?
When a heat pump fails in a Saint John rental, tenant complaints reach the property manager first. Service-YETI's Red Seal certified technicians handle in-suite repairs and common-area system failures across Uptown, the Lower West Side, and Millidgeville, coordinating access through one point of contact so managers are not fielding calls suite by suite across the peninsula.
Bay of Fundy exposure matters here: humidity, wind, and fog influence how equipment behaves, and this coastal climate differs from inland New Brunswick. We troubleshoot refrigerant faults, failed compressors, control errors, and airflow problems on all major brands, logging a digital service history per unit so condo boards can track recurring issues across the building.
Which Property Types Do We Service?
Saint John carries a wide range of older forms: heritage multi-unit buildings, small apartments and walk-ups across Uptown, the peninsula and the West Side.
What Multi-Unit HVAC Services Do We Offer?
Repairs & Diagnostics
Fast, accurate repairs and diagnostics on in-suite and common-area equipment. Saint John is a port city first, with Uptown, Market Square and the East Side retail belt anchoring its commercial and service employment.
Tenant Service Calls
In-suite service calls coordinated through the property manager, with tenant notices in advance. Saint John is defined by Uptown, King's Square, the Market Square waterfront, the Saint John City Market, Rockwood Park and Reversing Falls.
Common-Area HVAC Service
Rooftop units, furnaces, and shared systems serviced for lobbies, corridors, and amenity spaces. Uptown, the Lower West Side and Carleton, Millidgeville, the East Side and the central peninsula are the most useful Saint John place names.
Equipment Replacement
Replacement and installation coordinated with Greenfoot's installation division. Locals in Saint John say Uptown, not Downtown, and Reversing Falls with the masonry heritage streetscape signal real knowledge of the city.

Support for heat pump retrofit projects across one building or many. Saint John carries a wide range of older forms: heritage multi-unit buildings, small apartments and walk-ups across Uptown, the peninsula and the West Side.
Installations
New in-suite and common-area equipment installations. Bay of Fundy exposure gives Saint John humidity, wind and fog that make its coastal building conditions differ from inland New Brunswick.

"FIXED A LONG STANDING ISSUE I HAD FROM POOR INSTALLATION BY ANOTHER COMPANY!"
The two technicians Tanner and Halim were excellent, did a great job, very tidy, and identified 2 problems with my heat pump head, and fixed a long standing issue I had from poor installation by another company! Thank you very much, looking forward to using Greenfoot again.

"I ONLY WISH THEY INSTALLED OUR HEAT PUMP ORIGINALLY"
Great company to deal with. We hired them to move an existing heat pump after the original installer refused to help us. The estimator and the installer were both very polite, careful and thorough. I only wish they installed our heat pump originally. I would hire them again without hesitation.

"WHEN THEY LEFT THE HOUSE THERE WAS NO MESS TO CLEAN UP!"
The young chaps, Marlon Marcuflo and Sylvia Richard, were wonderful to deal with. They were extremely polite, very tidy and efficient in their work, were right on schedule and did an excellent job. When they left the house there was no mess to clean up. I would recommend Greenfoot Energy Solutions to anyone thinking of upgrading their home.

We hired Greenfoot to install 2 heat pumps. From the beginning to end - initial home visit to the final installation touches - they were wonderful to work with. Their entire team is extremely experienced, knowledgeable, and considerate; and were very accommodating.

"OUR OLD HOUSE FEELS LIKE A BRAND NEW CONSTRUCTION"
The Greenfoot Team did amazing work in our home. Our old house (built in 1959) feels like a brand new construction thanks to the ductless heat pumps, spray foam insulation and HVAC installed by the friendliest staff! Everyone we spoke to from Greenfoot was helpful and just seemed genuinely happy in their job.
