CroppMetcalfe has been fine. They're in the community all the time. They're known to be a reputable group, and so was the guy that came out. We actually bought a service policy from them.
I had a positive experience with CroppMetcalfe.
They come every year just to do the maintenance stuff. They do good work, and they're a good company.
Everything about CroppMetcalfe was perfect. They changed the air conditioning fan and did duct cleaning. I've been using them for ten years, and I like everything about them—they're A+.
I had a new furnace, a new hot water heater, and a new air conditioning unit installed, and they did duct cleaning for me. The experience was very pleasant; they were responsive and communicative, and I had no problems at all. I've been dealing with them for ten years, and I would give them an A rating.
CroppMetcalfe does regular HVAC maintenance and cleans the air ducts. They show up when we schedule the appointments. They're a very pleasant, grade-A company.
They did an inspection and recommended that a couple of things be replaced. They're responsive, and I like the way they do business. They're good. I'd give them an A.
CroppMetcalfe cleans the furnace and the vents, and I have no issues with them at all. We've had them for a good while. It has always been A-grade work.
The most recent thing they did for me was duct cleaning. The previous company I used sold out to CroppMetcalfe, so that's the reason I use them. They get an A from us.
CroppMetcalfe was very thorough. They cleaned up the ventilation system, which had been there for 30 years without ever having been cleaned. They made recommendations, and they told me what I should or shouldn't do. They helped me get the best kind of service for the equipment that I had in my house. They were very clean, uniformed, and trustworthy—A+.
