What to expect from LC Heating & Air
### Indoor Air Quality and Ventilation in Los Angeles Homes Modern homes are built tight for energy efficiency — excellent for utility bills but potentially problematic for indoor air quality. Without adequate fresh air exchange, pollutants including VOCs from building materials, cooking byproducts, CO₂ from occupants, and moisture accumulate indoors. California Title 24 now requires mechanical ventilation in new and substantially renovated homes for exactly this reason. LC Heating & Air installs and services whole-home ventilation systems throughout Los Angeles County.
Overview
### Types of Mechanical Ventilation The simplest form is exhaust-only: a bath fan or dedicated exhaust fan that pulls stale indoor air out, drawing fresh outdoor air through building gaps. More sophisticated are supply ventilation systems that introduce filtered outside air into the HVAC return duct. Most effective — and increasingly required in California — are balanced systems: Energy Recovery Ventilators (ERVs) that exchange stale indoor air with fresh outdoor air while recovering most of the energy from the outgoing air.
### ERV Installation An Energy Recovery Ventilator is well-suited to Los Angeles's climate. It brings fresh outdoor air into the home while simultaneously exhausting stale indoor air, and uses a heat exchange core to transfer both heat and moisture between the two airstreams — so you get fresh air without significantly increasing your cooling load in summer. We design, supply, and install ERV systems integrated with your existing HVAC system.
### Exhaust Fans and Makeup Air We also install and replace bathroom exhaust fans, range hood makeup air systems, and whole-house exhaust systems. Proper exhaust fan duct routing to the exterior (not into the attic) is required by California code and is essential for controlling moisture and preventing attic damage.

Verified reviews from Los Angeles homeowners who used our ventilation services service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
