Project: Install Natural Gas or Propane Furnace / Forced Air Heating System
Great local company here in West Chester, PA. Easy to do business with. Installers were courteous and professional. Lost my heat during the really cold week after Christmas. Great turnaround time and installed a new gas furnace/ac unit with it 15° to 20° outside. No problems 1 month later. Highly recommend.

Review by in Haverford, PA
Selling the house and wanted to assure buyers that the programmable thermostat was functioning properly. There had been some glitches. We had time constraints and Donnelly scheduled a technician to come out at 7:30 am. He diagnosed the programming on the unit and stayed for the time it took to measure the temp and assure us it was functioning well.

Project: Install Natural Gas or Propane Furnace / Forced Air Heating System
Professional crew, explained the system well when the work was completed. One reason I chose Donnelly was the completeness of the initial estimate (included licensing and insurance information).

Donnelly HVAC just finished up a complete HVAC installation at my home and they did an excellent job. I had a new furnace, AC system, and some ancillary duct work done and knew this was going to be a big job. Tom and his team were prompt to respond; provided solutions; and had the most competitive price out of three quotes I received. I didn't feel the sales pitch or scare tactics from Tom that I know I was receiving from the other companies. Josh and Lou did the install and Lou is a true artist with his craft. He was able to do great work installing new ducts and working with my existing ducts to balance the air flow. Josh and Lou worked hard and was able to complete the job in less than 3 days. Overall the new system is running great! My wife and I are very happy and will certainly use Donnelly again and I would recommend them to anyone.

Review by in Wayne, PA
Personnel are knowledgeable, punctual and courteous. The sales rep provided me with web links to evaluate the heat pump system he recommended and other systems for comparison. He also provided the web link to apply for a rebate from my electricity supplier. Removal of old system and installation of new system went smoothly. The installer provided instruction re changing filter, thermostat settings, etc.

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.
