What we do
From a failed capacitor to a full system replacement, La Vernia HVAC pros handle it all — AC, heating, air quality, residential and commercial.
Rooftop units, split systems, and ventilation for La Vernia offices, retail, and restaurants — serviced by techs who understand that downtime costs you money. Planned maintenance agreements keep your equipment running and your tenants comfortable.
A furnace that keeps tripping the breaker or blowing cold air usually has a fixable cause. La Vernia heating techs diagnose the electrical and fuel side, explain what is wrong in plain English, and quote before touching a wrench.
Dust, allergens, wildfire smoke, pet dander — La Vernia indoor air carries more than you think. We assess your home's air and install the right combination: high-MERV filtration, UV treatment, humidifiers, and dehumidifiers matched to your system.

Renovation dust, pet dander, wildfire smoke residue — La Vernia ducts collect it all. Professional duct cleaning in La Vernia with proper equipment, not a shop vac on a stick. Free quotes at (877) 317-0473.
Boilers last decades, but controls, circulators, and expansion tanks do not. In La Vernia, we diagnose boiler issues properly — combustion, water side, and controls — and repair only what is failing. Call (877) 317-0473, answered 24/7 in winter.
High bills and uneven comfort usually have a findable cause. Our La Vernia energy audits test duct leakage, measure airflow room by room, and use thermal imaging to find where your heated and cooled air is escaping.
A smart thermostat only saves money if it is wired and configured correctly for your equipment. Our La Vernia techs install and program thermostats to match your furnace, AC, or heat pump — and show you how to use the schedules.
