We've been using Rossoe Energy Services for the 18 years we've lived in our house. Called them originally because my parents had used them since the 1950s and they were one of the few companies I didn't hear my dad complaining about.
They have been quite helpful when we have needed to replace our heating system and we have used them on a contract basis for all the maintenance needs for both our furnace and our air cleaner (thus keeping the dust and fuzz to a manageable level).
They always show up on time and their service technicians seem friendly and knowledgeable. And more than once they have come to our rescue when called—solving whatever the problem was on the spot.
Since they're the only heating company I've used I can't make any comparisons. But based on experience, I would rate Rossoe a solid choice for your home HVAC needs.
