A selection of 337 homeowner reviews:
“Central did some insulation work for me, and they were super-duper. They came on time, they did the work professionally, and they did not leave a mess. I would grade them as an A+. I'd use them again and recommend them.”
“They were competent; they knew what they were talking about, and they did what they said they were going to do. They've added insulation and an additional filter to my air system. I'd give them an A.”
“They're always punctual and professional. They're my service provider for my HVAC system, but recently, they blew in insulation and sealed my attic. I would give Central Insulation an A. I've already recommended them.”
“They did blown-in insulation in the attic. They were prompt and timely, and they gave us a lot of information. They're an A.”
“They were on time and efficient. I would grade them A+.”
“They did a heat escape assessment. We had very little insulation in the attic. They replaced it, and it did make a huge difference. I would grade them an A+. I would recommend them to a friend.”
“They did a great job. They came and they did their job. They did insulation in the attic. I would grade them an A+.”
“I had a positive experience with them. It was fine.”
“I like the people that they send out—they are always mannerly, and they don't try to destroy your property when they come in. It's prompt, and they do a good job. I can't say anything negative. I'm on contract with them. They did their annual maintenance. They installed two heating and air conditioning systems, it's been a few years. They have put insulation in my wall. I would grade them an A.”
“I liked that they were considerate. They did neat work, and they did everything as promised. I have an annual contract with them for my heating and air conditioning, and they put insulation in my attic. I would grade them an A.”
