What to expect from LC Heating & Air

### Full HVAC System Installation in Los Angeles Installing a complete HVAC system is one of the most significant home improvement projects you can undertake. Done correctly, a properly sized and installed system delivers decades of reliable comfort. Done wrong, you pay for the mistakes every month in energy bills and premature repairs. LC Heating & Air performs complete HVAC installations throughout Los Angeles County, including new construction, retrofits in homes without existing systems, and full system replacements.

Overview

### The Manual J Calculation: Why It Matters Every HVAC installation starts with a Manual J load calculation β€” the industry standard for determining exactly how much heating and cooling capacity your home requires. We account for your home's insulation levels, window area and solar orientation, ceiling heights, local design temperatures, and occupancy. In the San Fernando Valley where summer design temperatures can reach 105Β°F, proper sizing is more consequential than most contractors acknowledge. An oversized system short-cycles and wastes energy; an undersized system can't maintain comfort on the hottest days.

### Ductwork: The Hidden Factor Most comfort complaints in LA homes trace to ductwork problems β€” leaky connections, undersized supply runs, poor return air design β€” not equipment failure. We assess duct condition as part of every installation and bring ductwork up to standard as part of the project. Installing expensive new equipment on a leaky, undersized duct system wastes money.

### Permits, Rebates, and Commissioning Every HVAC installation is pulled with all required permits from LADBS or the applicable city building department. We identify applicable rebates from SCE, SoCalGas, and TECH Clean California and handle the documentation. On completion, we commission the system β€” verifying refrigerant charge, measuring airflow at every register, confirming temperature split, and registering manufacturer warranties in your name.

HVAC Installation β€” by city

FAQ

Common questions about hvac installation in Los Angeles

How long does a full HVAC installation take?
A straightforward replacement in a home with good existing ductwork typically takes one day. A full new installation with ductwork in a home that has never had central HVAC can take 2–4 days depending on duct layout complexity. We provide a timeline in the proposal.
What brands do you install?
We install Carrier, Lennox, Trane, Rheem, Goodman, Daikin, Mitsubishi, and American Standard. We recommend equipment based on your home, budget, and efficiency goals β€” not brand preference. We present 2–3 options with honest analysis of each.
Do I need a permit for HVAC installation in Los Angeles?
Yes, always. HVAC installation involves gas connections, refrigerant handling, and electrical work β€” all of which require permits and inspections in Los Angeles. Unpermitted HVAC work creates insurance issues, resale problems, and safety risks. We pull all required permits as part of every installation.
What rebates are available for new HVAC installation in LA?
Available incentives vary by equipment type and efficiency level. Options include SCE rebates for high-efficiency AC equipment, SoCalGas rebates for high-efficiency furnaces, TECH Clean California rebates for heat pumps and all-electric systems, and federal tax credits for qualifying systems. We identify and document all applicable incentives.
Can you add central HVAC to a home that never had it?
Yes. Adding central HVAC to a home without existing ductwork is a significant project involving new duct design and installation through the attic or walls. We assess feasibility and provide a complete project scope. For some homes, a ductless mini split system may be a better solution.
How do you size a new HVAC system?
We perform a full Manual J load calculation per ACCA standards. This accounts for your home's square footage, insulation values, window area and orientation, ceiling heights, infiltration rate, internal heat gains, and local design temperatures. The result is the exact heating and cooling capacity your home needs β€” not a round number from a square footage table.
What is commissioning and why does it matter?
Commissioning is verifying that an installed system actually performs to specification. We measure airflow at every supply register, verify the refrigerant charge with calibrated gauges, measure the system's cooling and heating output, and test all controls and safety devices. A commissioned system is a verified system β€” you know it's working correctly from day one.
How long will a new HVAC system last?
A properly installed and maintained system in Los Angeles should last 15–20 years. Poorly sized or installed equipment, or equipment that is never serviced, often fails at 8–10 years. Annual maintenance and proper installation are the two biggest factors in equipment longevity.
