We own an 18 unit building purchased in 1967, which was a few decades old when my family bought it. It's still running on the original boiler, and a new heating system is long overdue. After a thorough investigation of the building's existing system, chimney, plumbing and water heaters, Ben from Five Lions provided a clear assessment of potential issues in layman's terms: advised me of the pros and cons of potential heating options, and a solution was recommended which was $30,000 less than the 2nd lowest quote. Both Ben and Five Lion's owner, Favio, are exceptionally helpful and knowledgeable and my family will be using the company to maintain and service their homes' HVAC systems as well. This company provides exceptional service at prices that are much lower than equally reputable competitors. It's not surprising that Five Lions is ranked so highly by customers, consistently receives top marks.
