How Does St Johns's Climate Impact Your Cooling Needs?
St Johns's hot, humid summers and variable shoulder seasons make energy-efficient air conditioning essential for year-round comfort. St. John's has a subarctic-influenced maritime climate — Canada's foggiest city with over 120 foggy days per year. July highs average just 21°C, but Atlantic humidity makes those temperatures feel sticky indoors. Winters are long and severe, with heating costs among the highest in Canada due to Newfoundland's reliance on oil heat. Mini-split heat pumps are the most cost-effective upgrade available to St. John's homeowners.

"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.

The Greenfoot Team did amazing work in our home.

Everyone we spoke to from Greenfoot was helpful and just seemed genuinely happy in their job.
