My inlaws, their neighbour, and I have been dealing with SAR for several years.
A friend of ours who is a widowed elderly immigrant had a contractor bolt on her like a thief in the night. He was a fly by night and went out of business, and didn't seem to care he was leaving her in the dark and out of pocket and a messy furnace situation.
She hired Tony and not only did he clean up the soot that was spewing throughout her house -- he made extensive efforts to see this man's insurance pay her for damages. Only SAR can touch her furnace now.
Tony, Samantha, Gina and his crew are absolutely top notch. They did a large and cumbersome HVAC install in my house and they utilized a relatively small space for the new washer and dryer. They were very friendly, polite, and very hard working. This wasn't an easy job. We are extremely happy.
If you are a tire kicker -- kick your tires and be cheap elsewhere-- they are probably not a good fit.
If you want to pay fairly and get top notch service on your furnace and A/C needs by trustworthy people then SAR is highly recommended.
