Calvert Comfort

When I questioned an initial report that my heating system had a potentially dangerous problem, Calvert's own very fine and accommodating president came to my home to do a follow-up check. After a thorough inspection which showed that the problem did not exist, he offered (actually, insisted) that Calvert compensate me for the "second opinion" I had gotten. This is service beyond reproach. I can recommend the company as highly ethical and providing outstanding service.
