5.0 Dorothy R. Claremont, CA

Really wonderful experience. Super fast communication and able to come out quickly to fix my furnace. They were very professional while at my home and honest. Trouble shot the issues until they found what was wrong. I would definitely hire them again and recommend to others.

5.0 Sara C. Glendora, CA

I recently had an issue with my air conditioning unit, and I contacted Climate Specialists for assistance. Their team responded promptly to my inquiry, scheduling a convenient appointment for the repair. The technician arrived on time, fully equipped, and ready to diagnose the problem. They quickly identified the issue and explained it to me in clear terms, outlining the necessary steps to fix it. Throughout the repair process, the technician demonstrated high expertise and attention to detail. They worked efficiently to resolve the issue, ensuring that my air conditioning unit was back up and running quickly. Their professionalism, expertise, and dedication to customer satisfaction truly set them apart. I highly recommend their services to anyone in need of reliable AC repair. Thank you for the wonderful service!

5.0 Jose C. Glendora, CA

Great service, communication and follow through. Would definitely call again.

5.0 Leo S. Diamond Bar, CA

I called Climate specialists for my heater that stopped working. Its been freezing lately so I needed to call someone ASAP. I called Climate Specialists and technician Dan came the very next day. He answered any questions i had and the pricing was fair. Will definitely be saving his number and keep him as my go to HVAC technician.

5.0 A. O. Diamond Bar, CA

Very professional and honest HVAC guy answered all my questions i had. He installed a brand new AC unit in my house and its been working great! Excellent service. I really recommend Climate specialists. Excited to have such reliable support just a call away.

5.0 Carla P. Chino Hills, CA

4.0 James M. Diamond Bar, CA

I will trust to provide future services!

5.0 Olga S. Diamond Bar, CA

Very courteous and punctual. Made some future recommendations, but did not force an up-sell. Would use this company again.

5.0 John W. Riverside, CA

They were absolutely one of the best experiences we have had in hiring a contractor to do work on our home. The technician was on time and stuck with the job over a two day period until the unit was working like new. (Ours was a 38 year old unit!) The cost was very fair and affordable. Would call them again in a heartbeat.

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.
