This was thorough, helpful service! Very good explanation of what was wrong and what was being fixed. My only hesitation from a full 5 stars is that it was quite expensive- HOWEVER I believe that this amount can be applied to a future new unit if needed soon. But we are cool again and for that I am relieved Will definitely call again, hopefully not needed soon!

Sayed was on time and a true professional. Through no ones' fault the option of installing a "Nest" system proved to be an issue. The price was not exactly what I had budgeted for but then again the price of gasoline is not what I hoped for either. The work is exceptional and my a/c is now ice cold. That's nice!

Sayed was wonderful Response time was super quick and given the fact I explained to Sayed that I was asthmatic and needed heat (my thermostat had died and I had no heat) he found some of his staff to come the same day and they worked from 4:34 pm to 10:00 pm and did not leave until I had heat Sayed followed the next day as well He was very considerate and the service I received was excellent I totally will recommend them Francine Boehm

I asked how soon they could install a new furnace, they said today. I hired them and had heat once again by 4 pm. A fast, quality installation and experience.

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.
