Great service

5.0 Eliot M. Leesburg, VA

Charles responded to my inquiry right away and we set an appointment for the next day. He was on-time and had the needed part on hand to fix my AC unit. He was also friendly and easy to talk with. I would recommend his service for your HVAC needs.,

I spoke with Mr. Pratt on Saturday morning and he told me he could accommodate me as his last appointment of the day. He came to our house on Saturday evening. He arrived about 7:30 PM and fixed our air conditioning system that night. He left about 11:30 PM. He was good and he was thorough and explained to us exactly the problem. I have a home warranty on my house and the company that the home warranty sent to me kept changing their price until I finally told them not to come to my home anymore. I then called one of the large and well-known HVAC companies in the area. They gave me a price of $3300 to which I said no. It was then I called home advisor and soon after Mr. Pratt of Maximum HVAC called. He fixed my AC for $704. The problem with my AC was not the expensive evaporator coil as the other company said but rather a valve which needed to be replaced and Freon needed to be pumped into the system. I told Mr. Pratt that I would put his name into our neighborhood directory of responsible vendors.

We would HIGHLY RECOMMEND Charlie Prat and Maximum Mechanical. We came home to find our Furnace had gone off. It was 8pm on a Saturday night and the temperature outside was 17 degrees. Not knowing who to call I went to home advisor and hoped to find and emergency number for someone who could help. Charlie did not receive the referral until the next morning, which was a Sunday. He called us at 9am and offered to come out. He stayed for three hours and did everything he could to get our burner going. He diagnosed the problem in just 15 minutes and the rest of the time he spent trying to get the part on a Sunday. He was professional and gave a fair price. I will definitely call on him in the future. He is THE BEST!. On Saturday night when the burner was out we called Michael and Sons because that was the only person I could find with an emergency number. A tech came out at 11pm and was here for 45 min. He diagnosed the problem as the Gas Valve Control. In total the job would have cost me 1k and he couldn't fix it until Tuesday. The problem really was the ignitor and the total price was 431.00 with Charlie Prat. So it just goes to show the big box store is not always the best option. Thanks Again Charlie!!

5.0 Philip R. Manassas, VA

Charles Prat, knowledgeable, punctual, quick to diagnose and good customer service. I believe industry wide the price markup on parts is a little excessive but found other contractors costs were either close or higher. Overall, getting quick service on a Sunday with below freezing temps was a godsend. Thank you!

2.0 Dan H. Gainesville, VA

Late by several hours so rescheduled and late by several hours again. Took way to long since always on the phone. Rushed important areas and thus the lacking quality. Will have to fix his mistakes myself, not exactly sure what I just paid for an used my entire afternoon and evening for

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)
