Our a/c system in our newly-purchased home was leaking. We contacted them (through HomeAdvisor) and they came immediately. The issue was caused by a clogged drain, and we were also told that the system had been set incorrectly.

Project: Install or Replace a Central Air Cleaner
They are experts in their field, they listen and understand their clients, they are honest and upfront, and they leave the project clean.

For the past 4 years I have depended on Cromwell Energy to perform annual preventive maintenace on my two furnaces / AC units, plus hot water heater. They always show up on time, friendly techs who know their trade, and are very thorough in assesing each component. They are neat in their work and clean up after the job is done. If there is ever a need for a call-back due to a minor item, they are prompt to respond and courteous. Their charges are reasonable for the amount of time and marerials they use. I will continue to use them in the future due to consistently great service. I will also recommend them to my friends.

I had a furnace installed 20 years ago. Since then it has been serviced by four (4) well-known Oil companies. To my dismay, not one could figure out why my furnace would get DIRTY as often as it did. It even plugged up within a year. Cleaning after cleaning ($$$ spent). I became very frustrated. Based on a friends recommendation, I called Cromwell Energy. I was amazed at the professionalism of the entire team. When Lou and Rich assessed the furnace they referred to the manufacturer and was advised that the burner that was originally installed and since replaced by another company was not the correct one to begin with! They corrected the problem and I have been trouble-free since. Thanks guys. I wish more companies would provide this type of service. You've got my business and I have since referred them to other family members who are just as pleased as I am. Keep up the good work! Your loyal customer.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
