I've had Service Specialties come in and do a couple of things over the past two years. They've done heating and air conditioning for us, and they also added some insulation to our attic. I thought they were a very professional group of people. They explained exactly what they were doing, and I felt that they were honest. I also like that they have a professional yet personal touch when you call the company. They're professional, honest, and high quality. I'd recommend their work.
