Dyand recently installed two furnaces and an air conditioning unit for us. I called Dyand and spoke with Melvin. Melvin came out to the house and inspected our existing furnace installs and made his recommendations. While he was at the house, I also asked about adding in an air conditioner to the quote. When he was done, we went over the quote and based on other quotes I received and the recommendations of others who had work performed with Dyand we went ahead with the installs. The Dyand technicians are quite knowledgeable and at the end of the day they reviewed what they had done, what their goals were for the next day and cleaned up after themselves. Dave was the lead technician for our install, and he always ensured I was kept in the loop during the installation process. Dyand has been in the business for quite a while, and I will use them for any follow up business in the future. They are a dependable company that will be providing service and support for years to come. Give Melvin a call if you have any questions.
