Heating, Ventilation & Air Conditioning
Total Comfort. Every Season.
Full-service heating, ventilation & air conditioning for rural NorCal properties — installs, replacements, repairs, re-ducting, and whole-house ventilation. Top brands, permit processing included, and a 5-year parts / 5-year labor warranty on qualifying systems.
One Team for Every Heating, Ventilation & Air Conditioning Need
From a furnace replacement on a cold January morning to a full central air cut-in on an addition, Armstrong's heating, ventilation & air conditioning department handles the complete scope. We work on split systems, mini-splits, multi-stage and dual-fuel systems, ground-mounted and rooftop package units, and whole-house ventilation — with permit processing handled in-house and top-brand equipment backed by industry-leading warranties.

Full System Replacement & Installs
Whether you're replacing an aging system or installing heating, ventilation & air conditioning in an addition or ADU, Armstrong sizes, specifies, and installs the right equipment for your home and climate. We handle all permit processing and final inspection coordination.

Split Systems, Mini-Splits & Package Units
We install and service the full range of residential heating and cooling configurations — traditional split systems, ductless mini-splits for additions and outbuildings, and ground-mounted package units. Rooftop package units are available for site-built homes and commercial structures.
Heating, Ventilation & Air Conditioning
Multi-Stage, Dual-Fuel & High-Efficiency Systems
For properties with variable heating and cooling demands, we install multi-stage and dual-fuel systems that optimize comfort and efficiency across NorCal's wide seasonal temperature swings. Top-brand equipment with 5-year parts and 5-year labor warranty on qualifying installs.

Re-Ducting & Duct System Upgrades
Leaky, undersized, or deteriorated ductwork undermines even the best equipment. Armstrong re-ducts entire homes and structures — improving airflow, reducing energy loss, and bringing duct systems up to current standards.
Heating, Ventilation & Air Conditioning
Whole-House Ventilation & Central Air Cut-Ins
We install whole-house ventilation systems and perform full central air cut-ins on homes that have never had ducted cooling. From attic fans and whole-house fans to complete duct system design and installation, we bring comfort to every room.
Heating, Ventilation & Air Conditioning
High-Grade Filtration & Hypoallergenic Systems
For households with allergy or air quality concerns, we install high-grade filtration systems, HEPA and hypoallergenic media filters, and UV air purification — integrated directly into your existing or replacement heating and cooling system.
Heating, Ventilation & Air Conditioning
Tune-Ups, Repairs & Relocation Services
Annual tune-ups extend equipment life and catch problems before they become failures. Our technicians diagnose and repair all makes and models — and when a remodel or addition requires it, we relocate existing equipment and ductwork to fit the new layout.
Industry-Leading Warranty Coverage
Every qualifying heating, ventilation & air conditioning installation Armstrong performs is backed by a 5-year parts warranty and a 5-year labor warranty — some of the strongest coverage available in the industry. We stand behind our work and the equipment we install.
