    Reese 1st arrived to look at the water heater. He was very professional and discussed how old it was and my options. I asked him for replacement estimates, which he gave me in absolutely no time. I had 4 different options, he thoroughly explained each one and I selected the one best for me. I knew exactly when he would arrive by texts and phone call which was great, he was very knowledgeable, taking the time to answer all my questions. I decided on a specific model and to my delight, Reese checked and Cornerstone was able to do the installation that same afternoon. Prior to Danny's arrival to install the system, I received a text and phone call to let me know when he would be arriving. He went straight to work, installed the new water heater and cleaned up completely when finished. He answered all my questions and was most helpful and knowledgeable. After he left and I was reviewing the documents that were emailed to me, I had some questions and called in and spoke to Angie. She went out of her way to explain the program that was set up for me, was very knowledgeable and answered all my questions very professionally. This company is top notch in my book, I couldn't have had a more pleasant experience all around, Thank you All, Reese, Danny and Angie for all your efforts on my behalf. I will absolutely be recommending this company to my friends.

    First of all, sign up for their Platinum Customer status -- it's worth every penny of the $14.03 I pay a month! They provide an annual inspection of all AC/Electrical/Plumbing at no additional charge! I have had many occasions to use Cornerstone, whether for an emergency or routine situation. The CSRs are all very pleasant and accommodating, and seem to genuinely care about their customers. The professionals are all knowledgeable, courteous, respectful, honest, and trustworthy. Perhaps, even more importantly, they take the time to explain the "whats" and "whys" of their work. I would not consider any other organization to perform the services that Cornerstone Pros specialize in! EXCELLENT in EVERY WAY!

    Response from Company:

    Thank you very much and it is our pleasure to serve you!

    Very professional and clean; Martin showed up early to our scheduled appointment and the work was completed efficiently; they cleaned up after the project was completed; all costs were explained. will recommend Cornerstone Pros for all plumbing and ac projects

    5.0 John P. Land O Lakes, FL

    Cornerstone is a great company with dedicated friendly employees. They communicate well and are punctual. We use them for all our electrical, plumbing and AC needs. I would recommend them to anyone, there may be cheaper companies out there but as the saying goes you get what you pay for, and with Cornerstone you get value, quality and service but moistly peace of mind because they stand behind the work.

    5.0 Michele W. Sun City Center, FL

    Technician was professional and courteous. Came in, assessed the problem and made repair quickly.

    5.0 Willie D. Wesley Chapel, FL

    I found Cornerstone Air Conditioning & Heating, Inc to be knowledgeable, honest and provided a fair competitive price for the services they provided. I'd recommend them to others and I'd have them do other services in the future.

    5.0 Spencer C. Tampa, FL

    I received good service from Cornerstone. They came on time. It was raining outside and muddy and they took off thier shoes so no mud got on the floor. I would recommend them.

    5.0 George B. Tampa, FL

    Timely,friendly and good experience

    5.0 Rose R. Land O Lakes, FL

    They were very nice courteous and very professional. I watch what they were doing to my air conditioning system just in case they would try to rip me off, but they did everything that they promised. I would highly recommend them. Thanks cornerstone.

    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)
