5.0 Ron A. Fremont, CA

very professional and efficient

3.0 Esther H. Fremont, CA

The reason for the 3 stars is because though they did the work they said they would, they didn’t do a good cleanup afterwards and left parts and debris under the shed where the heating units were kept. To me, the cleanup afterwards is just as important as the work itself and is a sign of professionalism. The work also went longer than the estimated time so it would be better if they gave a longer estimate to allow for work-related delays.

5.0 Lola T. Fremont, CA

Did great job and so far after two years no problems with my central heating. Had new Lenox heating system installed in 2015 by them.

0.50 Michelle J. Alameda, CA

Kesar was awful, if i could give zero stars I would, DO NOT HIRE HIM. He just yelled at me over the phone. He told us he'd be in today to repair a job he originally preformed and he left us waiting for an hour and a half before we called him asking where he was. He proceeded to tell us he'd come the next day. If we didn't call him he would have left us waiting for him! When I called him to politely let him know that tomorrow was a really busy day and we needed to be sure he'd be here on time, he proceeded to yell at me. I have never been treated so badly in my life, and I work in customer service.

2.0 Juliana W. Fremont, CA

It was very hard to get them to fix a problem ( a duct they installed that disconnected from the heating register) despite their written guarantee of work quality for 5 years. It took me over a one month and a final note of bringing my case to BBB to resolve before I got a response. Meanwhile, I called, emailed and texted the owner many times. BTW, I even drove to their "office" once - only to find out that it was the owner's own house - and no one answered the door. Ironically, we recently tried to look for a contractor via Homeadvisor.com to add an A/C system to our house, and Gosal being one of the top contractors on the list, I got a call from the same owner almost immediately!

2.0 Bal S. Fremont, CA

We hired Gosal heating and air conditioning to install a new AC system in our house. His price was reasonable and he was able to come within 1 week to do the installation. After he installed and left, we noticed water leaking around the AC system. We called and scheduled for him to come and take a look. After asking Gosal to return back, 3 unsuccessful attempts to repair it later, we asked him to remove his system and return our money. After negotiation, he returned 80% of our money back and took back his system. I would not recommend hiring this company.

4.5 Connie R. Santa Clara, CA

Fast, efficient and friendly. Good Price.

5.0 Kim D. Hayward, CA

Very professional and efficient as well as most reasonably priced for all the work involved installing our new furnace.

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.
