Cromwell Energy for HVAC Services in CT


    Cromwell Energy’s sterling reputation as a leader in HVAC service for Connecticut is due to a few key guiding principles.

    1. We value the relationship we have with customers and provide dependable HVAC service at a fair price.
    2. We are available 24/7 to respond to our customer’s needs; whether it is a heating issue in the winter, or a cooling issue in the summer.
    3. We stand by our work. There is a reason why our Connecticut customers stay with us year after year: our dedication to honesty, reliability, and professionalism.

    Cromwell Energy installs state-of-the-art heating and cooling equipment.  We carry the most reliable product lines, with proven HVAC service track records.  Cromwell Energy also uses the HEATDOC™ fuel additive in our heating oil to enhance the performance of your oil system. We believe that proactive care and maintenance of your system is the key to increasing the longevity of your equipment, and we include a free tune-up in all of our maintenance plans.

    Our technicians are equipped with the most current technology to ensure your HVAC problem is diagnosed and solved expeditiously.  We invest in our technicians; all of our technicians are insured, licensed, and trained.  When our technicians arrive at your house or place of business, they will be in uniform, polite, and have the utmost respect for your property.  Most of our customers know our technicians and office staff by name, fostering a level of trust not possible with large, impersonal HVAC companies.

    Another key reason to choose Cromwell Energy is our long-standing presence in the Connecticut marketplace.  Other HVAC companies may cut corners on their financial management, insurance, or adherence to State and Federal regulations. At Cromwell Energy, we guide our business using the best practices in the industry. We believe that sound business practices are the foundation for long-term success, ensuring that we will be there for our Connecticut customers for years to come.
