Frequently Asked

Real answers from Roman.

How much does HVAC installation cost?

A central AC replacement in LA typically runs $8,000–$18,000 depending on system size and efficiency. Full HVAC system replacements (furnace + AC + ductwork) are usually $15,000–$35,000. Mini-splits are often $4,000–$8,000 per zone.

How long does HVAC installation take?

Most residential HVAC replacements complete in 1 to 3 days. Full system replacements with new ductwork can take 4–7 days.

Should I repair or replace my HVAC system?

A good rule of thumb: if your system is over 15 years old and needs a major repair (compressor, heat exchanger), replacement usually makes more financial sense. Newer systems (under 10 years) are typically worth repairing. We'll give you an honest assessment.

What HVAC system is best for my LA home?

It depends on your home size, insulation, duct configuration, and climate exposure. LA's moderate climate makes heat pumps increasingly attractive (they replace both AC and furnace). We do a load calculation for your specific home before sizing any system.

Do you handle Title 24 compliance for HVAC?

Yes. California Title 24 applies to any HVAC replacement or new installation. We handle load calculations, duct testing, and HERS verification where required.
