Of the five bids I received, Michael Bonsby Heating & AC company proposed the best value for the price. From start to finish, through removal of the old furnace to installation & operation of the new furnace, the service technician was knowledgable & experienced in doing the work, and helpful in answering questions and explaining the use and operation of the new furnace. The office staff was also responsive and courteous whenever I called with questions or scheduling of installation. I'm very satisfied with this company and recommend them highly.

I received six estimates for replacing my air conditioning system. Of the six, four came in at a reasonable price including the estimate from the Michael Bonsby Company. Three of the four estimators made a good impression but the one who impressed me the most was David Lux of Michael Bonsby. He spent the most time, provided the most information, and fully answered all of my questions in all of my contacts with him prior to signing the contract. Even after I signed the contract, had the system installed, and made final payment, David Lux was still very prompt in answering my inquiries. So far I am very happy with the air conditioning system installed by and I would highly recommend the Michael Bonsby Company if you ever need to replace your air conditioning system.

Michael Bonsby installed my new heat pump incorrectly. The air filter is supposed to have 3 channels that hold it in place. They made a mistake and only installed two channels. At the back, they installed a bumper. When the fan started up, the filter lifted up in back since there was no channel to hold it in place. This meant that all the lint bypassed the filter and stuck to the heat exchanger above. My heat exchanger became clogged with lint. When I called, they sent a technician out who wanted to charge me $450 to fix the problem. I told them that this was still under their 5-year warranty and they should fix it for free. The lint had also caused water damage to my new laminate flooring. I called many times but they did not call me back or fix the problem so I filed a complaint with the better business bureau and the Maryland Office of the Attorney General. This got a response from the General Manager who requested that I send him the cost of the contractors I hired to fix their problems. I sent the costs and have yet to hear back from the General Manager. This company does not honor their installation warranty or have any customer service. I would not recommend this company to anyone.

The Service Technician was very professional and explained things. I signed a service agreement with the company for our two-zone system. So far so good. Our furnaces were serviced.

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)
