5.0 Jonathan B. Shillington, PA

I am very thankful that I found DG Mechanical on Home Advisor. After getting a few estimates from big name companies for getting central air conditioning installed in our home with existing ductwork I was getting exhausted with hearing all the upsell tactics. Derek was straightforward and prompt with all communications and very fairly priced. I felt even better after the work was done and seeing how nice and neat he left everything. While we aren’t using the air conditioner just yet it won’t be long now and we have Derek to thank during the upcoming hot summer days for keeping us cool and comfortable. I highly recommend DG Mechanical for all your HVAC needs.

5.0 Kathy B. Reading, PA

We had been having issues with our AC system for years and this company came in and found the problem right away. Took the time and had patience to figure it out and didnâ t charge me a crazy price to fix it!

5.0 Carol Z. Reading, PA

Derek did a great job. Price was fair, answered all our questions, cleaned up after himself. Also, much quicker than I ever imagined!

5.0 Denzil B. Reading, PA

5.0 Brenda D. Reading, PA

Derrick was quick in getting back to me and was able to get to my home quickly. My furnace wasn't heating and he was able to quickly identify the source and repair. Also Derrick was able to provide me a quote on other problems that will arise in the future. Very respectful and wore a mask.

5.0 Evlogi I. Birdsboro, PA

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.
