Although there are undeniably many good HVAC providers in the greater Los Angeles area, the reality is that the majority are not quality contractors. Many consumers fall victim to a poor choice because of what seems the cheapest price. The question is, and the question you should always ask is why are they cheaper?

Bargain HVAC Contractors vs. Around the Clock Heating and Air Conditioning

1.   Do they pull city permits? **
2.   Do they perform the installation to code? ***
3.   Are they qualified to evaluate the entire house as a system? ****
4.   Do they own the diagnostic tools required to properly evaluate and install your systems? *****
5.   Do they know how to use those diagnostic tools? ******
6.   Do they have workers compensation insurance?

Around the Clock Heating and Air Conditioning

**We will only do a permitted project.
***We don’t just meet current code requirements, we exceed them!
****ATC Heating & Air is a licensed contractor and is thoroughly trained in evaluating your heating and air conditioning system.
*****We have all the latest state-of-the –art diagnostic software, flow hoods, blower doors, title 24 energy calculation software, combustion diagnostic tools, refrigeration circuit analyzers, and more, all designed to properly diagnose and install your HVAC systems.
******Around the Clock Heating and Air Conditioning carries all required Workers’ Compensation and liability insurance.

Having the job done right, complying with codes, and maintaining adequate insurance is important for liability reasons and protects your expensive investment. If an insurance claim is filed due to a fire or an accident that is related to unlicensed work or work for which no permit was obtained, your insurance company will more likely than not dispute the claim and your policy could be void leaving you totally unprotected.

Poor installation workmanship could cost you even more to correct or bring up to code compliance than the original job itself when you sell the house.

If an installer or technician is injured while installing or repairing your HVAC system and the contractor is not insured, you as the homeowner can be held liable.

Remember, the cheapest price gets you the cheapest job. Sometimes it works, most of the time it doesn’t.
