They came right away to replace the old furnace. I was completely satisfied with their service.

5.0 Jeff G. Norwich, CT

Everything a consumer would want when looking to hire someone for a major job. Called on a Sat., came on Sun., later that day sent a quote. Were back on Mon., removed the old boiler. On Tues. installed the new system. Very efficient, done a great job, and was very affordable. Everything you would want when having to replace a major component of your house. It looks so clean and done well. Highly recommend Cawiamca to anybody.

5.0 George R. Old Saybrook, CT

My wife and I were selling our Old Saybrook second home and needed the boiler replaced quickly and economically. Ron Pelletier immediately responded to my request for help and with his excellent technician, Jeremy, got the job done and also took care of some air conditioning issues as well. He was a pleasure to work with and responded quickly to any questions I had. I plan to use him at our primary home in Glastonbury as well.

5.0 Joseph B. Null, CT

I was in the market for a ductless AC system for my house. With a project like this, it is wise to get multiple estimates and do your research. Cawiamca came right away to provide me with an estimate, came in at the best price, and could start the work the soonest. They installed three head units in the bedrooms and one in my living area. They left no mess in my home and placed drop cloths at the entrance. They went the extra mile to make sure I was happy with my AC system and stand behind their products and labor. I would highly recommend them.

5.0 Hongyu K. Norwich, CT

Ron and Jeremy really cared about their customers. Jeremy came to my rescue for the oil tank leaking, did a great job patching up the leaks and replaced the tank right after when the weather permitted.

5.0 Barbara S. Moodus, CT

Nothing but good things to say about this company, would definitely recommend them to anyone

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)
