After a quick response in a challenging environment, Pennington stayed professional and focused on completing the repair efficiently and in a timely manner. I definitely appreciate how quickly the repair was done.

5.0 Dani Warden Google Review

Nate is absolutely amazing, a very effective communicator especially to those who don’t work in the industry and might not understand the ins & outs. He even helped me save money versus a competitor trying to oversell based my lack of knowledge.

0.50 Paul B. Littleton, CO

The technician for Pennington showed up late and did not call to advise that he would be late. The technician from Pennington was not properly trained to do brazing. The technician promised to come back the following day but never did and never called. The owner Ben did not respond to a call the next day. I cannot believe that Angie would recommend this company to me for work. I am very disappointed with Angie and with Pennington.

Response from Company:

I'm sorry that this was your experience. Those individuals no longer work for this company and Ben was never the owner.

0.50 Pat J.

They installed a boiler on Oct 31st 2020. There was an immediate system failure and they had to come back. On Nov. 10th there was a water leak they had to come back twice following that there was a gas leak in March. Excel found a leak at the boiler. They tried to bill me for that repair which I contested and recently I had a new water leak from pipes they installed and they have voided their warranty on workmanship because they are tired of coming back. I am tired of calling them. If I could give them a negative 5 stars I would.

Response from Company:

I'm sorry that you had this experience under the previous management. That individual is no longer affiliated with my company.

$535.00. 5 minutes on the roof and they knew motor needed replaced on swamp cooler and went off to buy new one. Put motor in and took about 10 minutes, but it stopped working 15 minutes after they left. They eventually came back, said the cage needed cleaning, spent about 10 minutes on it and left. It stopped working again and when called the third time, they told us we needed to get up there and really clean it and spray cage down with lubricant. The reason we hired someone was to avoid getting on the roof due to physical issues. When I pushed, they said they could do it for another large sum. I refused and got someone else to help. Hired this company to get our swamp cooler running and they did not do this. Nice guys, though.

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.
