Review by a customerin New Castle, DE Project: Install Natural Gas or Propane Furnace / Forced Air Heating System
The estimate was inclusive providing 2 options for installing the new heating system. Roger only provided the estimate, the Real Heroes were the 2 men that actually installed the Heating System. They were excellent, very professional, provided instructions as to how to use the new heating system. I was very impressed with their effeciency, professionalism and kindness.

Review by a customerin Wilmington, DE Project: Install Natural Gas or Propane Furnace / Forced Air Heating System
The Technicians were very well trained and knowledgable. However, I was a little disappointed in the sales pitch.
1. I already knew the price for the Furance was fair. However I felt that I was being pressured to make a decision before the Sales man leaving.
2. I never received a follow-up call regarding the furnance.

They were very professional from their sales to installation. They were accomodating and got me into their schedule quickly. When the new unit had a problem they were on the scene immediately. They also had experienced technicians and a supervisor stop in during the install.

Salesman was easy to communicate with and we arrived at a deal that was price competitive and met our needs. Installation team arrived timely, completed the job in a day, and answered all our questions about the features and use of the products.

Good experience, good price, nice sales person and installation team. One oil fitting required a call back to tighten.
