CORE HVAC SERVICES

Primary HVAC Services

Heating, cooling, and the systems that move conditioned air through your home. This is what we do — and what every other service we offer is built around.

🔥

HVAC Repair & Installation

AC, furnace, and central system repair plus right-sized new installations from BPI- and NATE-certified technicians.
🌡️

Heat Pumps & Mini-Splits

High-efficiency heat pumps, cold-climate models, and ductless mini-split HVAC for room-by-room comfort.
🚨

24/7 Emergency HVAC

Same-day dispatch across NW Georgia when the AC quits in July or the heat fails in January.
🛠️

HVAC Maintenance Plans

Twice-yearly tune-ups, priority dispatch, and member discounts on parts and new equipment.
WHOLE-HOME HVAC APPROACH

HVAC-Supporting Services

Insulation, ductwork, IAQ, encapsulation, windows, and more — each one a building-science component that lets your HVAC system run at design conditions instead of fighting the house. None of these are standalone trades. They're all part of how we deliver HVAC.

🏠

HVAC-Integrated Insulation & Air Sealing

BPI-certified attic, wall, and crawlspace insulation that seals the envelope so your HVAC equipment runs at the conditions it was sized for.
🔧

HVAC Ductwork & Custom Sheet Metal

In-house sheet-metal shop at 519 Pine Street — perfect-fit ductwork fabricated on site, rare for residential HVAC contractors.
🌬️

Filtration, UV, fresh-air ventilation, and dehumidification that ride on your HVAC system to clean and condition every breath.
💨

Duct Cleaning

HVAC duct cleaning and sealing for restored airflow, lower static pressure, and better system efficiency.

BPI-certified diagnostics — blower-door, duct-leakage, infrared — that identify the HVAC efficiency opportunities hiding in your home.
🏚️

Crawlspace Encapsulation (for HVAC Performance)

Sealed, conditioned crawlspaces that protect ductwork, control humidity, and let your HVAC equipment work less for the same comfort.
🚿

Water Heaters

Tank and tankless water heater installation, integrated with your whole-home HVAC and energy strategy.
