When it comes to installing, maintaining or repairing a central heating and/or cooling system, the most important step is finding the best HVAC contractor in Los Angeles. Here are some tips to steer you in the right direction.
Los Angeles also makes this choice harder than it looks. The Valley runs hotter in summer and colder on winter nights than the coastal neighborhoods, and a contractor who works mostly near the water may size equipment for a climate your home does not have. Look for someone who works your specific area every week.
Family members, co-workers, neighbors and friends are good sources for recommending a contractor, if they’ve had similar work done satisfactorily. In fact, they might even be willing to show you the finished results!
Although there’s sometimes a conflict of interest that can lead to a biased assessment, you can still request information from the contractors’ suppliers and subcontractors. Just don’t rely on that information alone.
Request testimonials from local clients, along with their names and contact information. Once you have this information, use it!
You simply aren’t going to find the best HVAC contractor Los Angeles operating solely out of his van with a mobile phone. There must be a physical business address, even if it’s an office attached to a home. There must also be a working office phone that doesn’t rely on cell towers, battery chargers and signal strength when clients need to make contact.
When it comes to home maintenance, repairs and improvements, few things are more frustrating than trying to chase down a contractor who takes a deposit and never shows up to do the work, disappears after deciding that a partial job is sufficiently completed or leaves damages behind.
A licensed contractor will meet the requirement to carry insurance which provides an extra peace of mind and protection for customers in the event of any unfortunate events that leave you with issues during a project. If anything occurs, it would be the contractor’s liability insurance rather than your own homeowner’s policy that would cover the damages. Besides liability insurance, licensed contractors also carry workman’s compensation insurance. If one of the contractor’s workers gets injured while completing work on your HVAC system, you will not be held responsible. Hiring an unlicensed worker that becomes injured while on the job opens the possibility of you being sued. Not only would you be liable for their medical bill, but you could be forced to pay any lost wages.
Licensed contractors have extensive training and experience. Due to the nature of HVAC equipment, extensive education and training is required to earn an HVAC license. This can assure they are knowledgeable and have the necessary skills to complete HVAC repair, maintenance or HVAC replacement/installation. If you hire an unlicensed technician, you cannot prove they are skilled or competent to complete any HVAC service they say they do.
Every state has specific laws for how HVAC contractors repair and install HVAC systems. Licensed experts must uphold certain standards and are always up to date with regulations and building codes and know which work requires permits. Once they earn a license they cannot ignore the licensing body. An unlicensed technician may ignore these guidelines putting your safety at risk and may cost you more money down the line. For the state of California, you may check if a contractor has current license on CSLB website.
Along with the requirement for California State licensure and registration of all contractors, the state license number must be displayed on any and all of the contractors’ advertising. This makes it very simple to gather pertinent information, such as the current licensing status and any complaints that have been made.
Ignoring the opportunity to check up on a contractor is like volunteering to be the victim of a con artist. Protect your personal safety, the integrity of your home and your finances by making a simple check. It’s FREE.

“Licensed” is a broad word. For heating and air conditioning work in California, these are the specific credentials to ask about by name.
For heat pump projects there is a fourth. California rebate programs such as TECH Clean California require the installing contractor to be enrolled in the program (and trained, for income-qualified incentives), so an unenrolled contractor cannot offer those incentives at all. We cover this in detail in our guide to why TECH Clean California requires an enrolled contractor for heat pump incentives.
Verify that a contractor has existing (and adequate) insurances before signing any contract or allowing any work to commence on your property. If a contractor can’t produce a copy of the Certificate of Insurance, request the agency name and contact information to verify that a commercial policy is in place.
If there are employees, there must be workers’ compensation insurance. It should be adequate to cover all costs of any workers’ injuries on your property, including any rehabilitative services that could be included as medical expenses.
How do you know if the contractor has adequate workers’ compensation insurance? It’s as easy as contacting your own insurance agent to see if it’s deemed to be enough to protect you from any future claims. Your agent can also inform you of what work-related coverage is included under your existing policy.
Both types of insurance must be fully addressed, in writing, in any contract submitted by a California licensed contractor.
The Contractor License Bond covers a mere $12,500 in work. It might not be enough to cover the cost of your project or the accrued cost of multiple consumer complaints.
Discuss bonds with any potential contractor. There could be a Contract Bond or a Blanket Performance And Payment Bond in place, in addition to the required Contractor License Bond.
After soliciting references from those around you, and verifying contractors’ information, you might still be a little unsure about which contractor is the best for the job. Now what? Take a few quick and final steps.
Go to the rating and review sites that are available online such as Yelp, Four Square, and even the BBB (Better Business Bureau). This will give you a general feeling for the overall reputation of the contractor. Inquire in your online community forums. Finally, use a search engine like Google with terms like ‘contractor’s name + review’ or ‘company name + complaints.’
Ask family and friends for references and referrals. Another option is to research online local contractors in your area. Many search engines or review sites will provide necessary information such as company website, contact information and reviews all on one page. Read what past customers share about the company and their experiences.
Be sure to get written estimates for all contractors you are considering hiring. Compare cost, energy efficiency and warranties for each proposal. It may be that the lowest price is not the best deal if the system that is installed is not the most efficient since your energy costs will be higher. However, keep in mind that neither the highest price or the lowest price is a true indicator of quality work or value. Most reputable companies will work with you to find a cost-effective solution for your needs. Keep in mind that often smaller or family owner companies will provide high quality work because they do not rely on a certain sales volume to cover their high overhead. Lastly, be sure that once you make a final decision that any questions you may have are answered and fully explained before you sign contract.
The license and insurance checks above screen out the worst outcomes. These four questions separate a competent contractor from a good one.
