Dilling Heating &Cooling did work done right.

5.0 Diane & jim R. Morrisville, PA

We converted from oil heat to a heat pump. They were very professional and efficient with great customer service. We are very pleased with their work.

5.0 Donna T. Langhorne, PA

I have bee very happy with their work ethic, the people who did the work and the salesperson. However, since it was just finished yesterday, I cannot give an honest review of the parts until I have had a chance to use them for a period of time.

5.0 Chris C. Ambler, PA

No comment.

5.0 Brenda W. Morrisville, PA

Came out and assessed the job in a timely manner. Once I decided to use them the job was scheduled in a matter of a day or two and the job was well done within a half a day. I would highly recommend this company

1.0 Dennis S. Mount Laurel, NJ

A joke

5.0 Lisa M. Cheltenham, PA

Hector was terrific! He examined the syst, which was installed last year by another contractor and advised me on what had been done incorrectly and inefficiently ( things which make it harder to service). He also pointed out other ways to improve my heating efficiency and was knowledgeable, instructive and polite! I will definitely call Dilling again and again!

5.0 Susan B. Willow Grove, PA

Excellent service and work.

5.0 Keith H. Feasterville Trevose, PA

Great company. Andrew was honest about what was wrong and gave me options on how he could fix the problem. He got the work done quickly and gave me a reasonable price.

4.0 Sean O. Morrisville, PA

They stayed on top of a difficult job until it was done.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

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.
