17 questions we get every week
Straight answers, no sales pitch. Pricing figures are typical Los Angeles ranges, not quotes.
How often should I change my air filter?
For most Los Angeles homes, every 1 to 2 months during heavy use. If you have pets, allergies, or live near a freeway, change it monthly. A clean filter improves air quality and reduces energy costs significantly.
Why is my AC blowing warm air?
Common causes include a dirty air filter, low refrigerant, a frozen evaporator coil, or a failing compressor. Turn the system off and call Cool Breeze LA for a diagnostic at (310) 469-1979.
How long does an HVAC system last in Los Angeles?
A well-maintained central AC system typically lasts 15 to 20 years. Furnaces can last 20 to 25 years. Systems that miss regular maintenance often fail 5 to 7 years sooner.
How much does AC repair cost in Los Angeles?
Minor repairs typically run $150 to $350. Refrigerant recharge runs $200 to $500. Major repairs like compressor replacement can be $800 to $1,500 or more. We always provide an upfront written quote.
Should I repair or replace my HVAC system?
If repair cost exceeds 50% of a new system price AND the unit is over 10 years old, replacement is usually the smarter investment. We provide honest, unbiased advice.
What is a SEER rating?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an AC unit converts electricity into cooling. Higher SEER means lower energy bills. California requires a minimum of 14 SEER for new installations.
Do you offer financing for HVAC installations?
Yes. Cool Breeze LA offers flexible financing options for new HVAC system installations. Ask about our current terms when you call.
How quickly can you respond to an emergency?
We answer emergency calls 24H and aim to dispatch a technician within 1 to 2 hours anywhere in the greater Los Angeles area. No extra charge for nights, weekends, or holidays.
Do you service all HVAC brands?
Yes. Our technicians are trained on all major brands including Carrier, Lennox, Trane, Goodman, American Standard, Rheem, York, and Bryant.
Is duct cleaning worth it?
For most Los Angeles homes, professional duct cleaning every 3 to 5 years improves air quality and system efficiency, especially after renovations or if you have pets.
Do you charge a diagnostic fee?
Yes, repair visits have a diagnostic fee, and it is the same at 2 AM as at 2 PM. We never add overtime charges. After the diagnosis you get a written estimate before any work begins, so you decide with the price in front of you. More on what a diagnostic fee should cover.
Will you try to sell me a new system?
No. We won't push a replacement when a repair will do. If your system is older and the repair would cost a large share of a new one, we explain both options and put the numbers in writing so you can compare. Got a quote that feels high? Read when a second opinion is worth it.
Are your technicians employees or subcontractors?
Our technicians are EPA certified and are our own W-2 employees. We never send subcontractors to your home.
Are you licensed and insured?
Yes. Cool Breeze LA is a licensed HVAC contractor, CSLB #1154105, and we are bonded and insured. You can look up our license on the California Contractors State License Board website.
What are your hours?
We are open 24 hours Sunday through Thursday and 9 AM to 3 PM on Friday. We are closed Saturday. Same-day service is available in most of Los Angeles.
Do you give free estimates?
Yes. Most repairs can be estimated free over the phone, and installations and replacements get a free in-home estimate. Air duct cleaning includes a free diagnostic and inspection.
Do you guarantee your work?
Yes. Repairs and installations come with our workmanship warranty, on top of any manufacturer warranty on the equipment.
