    Derek did an outstanding job. Highly professional, honest and he did a quality job. I will definitely use him in the future and will recommend him to family and friends.

    5.0 Phil A. Corona, CA

    Every once in a while you run into a service contractor that just feels right from the first meeting. Derek hit all the right buttons immediately and continued the high level of service all the way through the full HVAC ducting install. Every question I had was answered fully. The system now performs like new. I've already asked him about a mid summer compressor service. I would highly recommend Derek for anyone's HVAC install and service needs.

    5.0 Martin K. Rancho Mirage, CA

    Derek did great job, installed new thermostat and also check AC. I would highly recommend him. Thank you.

    5.0 Jefferson A. Apple Valley, CA

    I appreciate the fact that this company came out to Apple Valley, to perform a swamp cooler maintenance service for me. I like to keep up on my routine equipment maintenance so that when I need my units they work as expected. The service was fast, professional and efficient. I will use them again next year for my swamp cooler and my air-conditioner and heater units.

    5.0 Audulio R. Highland, CA

    Mr. Lenz was a total professional. He showed up on time and did a great job of identifying the problem and gave me a fair and honest evaluation. He was honest and completed the job quickly. Our ac/heater unit is working the way it was meant to work. Extremely pleased.

    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.
