Carlos installed my Ecobee in a very short time. Came in the same day to do so. Also checked our ac unit. Will definitely be working with him and his company in the future!

My old GE system is a heat pump with an air handler. As such it didn't have a common wire running to the thermostat. These guys came in and knocked this out in a couple hours and the new Nest thermostat works great. The technician worked with his supervisor over the phone and between the two of them were able to figure it out. Bottom line, these guys knew what they were doing and their price was competitive.

A/C controller board burnt out, we were worried it would be a much more expensive compressor repair. Owner came out to do the job; he was personable and knowledgeable, made sure we saw what was wrong and what he was going to repair and charged a reasonable rate. Also replaced our filter cleaned a few components in our elderly (30 year old) HVAC system for free (while he was troubleshooting) and gave us a very reasonable ballpark estimate on what it would take to replace the system for our small home than previous inspectors had. He also gave us tips on how to keep it running efficiently for 2/3 more years until we could save to replace it.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
