🏡 **From 2 Stories to 3 — A Complete Heating & Cooling Transformation!** 🔥❄️
When a Bozeman homeowner expanded their two-story home into a three-story home with an additional dwelling unit (ADU), the heating and cooling system needed a major upgrade, too!
That's where the Sweet Pea Heating & Cooling crew came in! 💪
The original single-zone HVAC system was completely replaced with a new two-zone system featuring a modulating furnace and modulating air conditioning, designed to deliver more precise temperature control and comfort throughout the expanded home.
Here's a look at what went into this project:
🔹 **New Two-Zone HVAC System** – Replacing the original single-zone setup to provide more customized comfort throughout the home.
🔹 **Modulating Furnace & Air Conditioning** – Both systems can automatically adjust their heating and cooling output to match the home's needs, providing more consistent temperatures, improved efficiency, and greater comfort.
🔹 **Cold-Weather ERV** – An energy recovery ventilator that brings fresh outdoor air into the home while helping reduce energy loss. Especially valuable in our Montana climate!
🔹 **Mini-Split Systems** – Providing independent heating and cooling control in additional living spaces.
🔹 **New Garage Heater** – Another addition to the project, helping make the garage more comfortable during those cold Montana winters.
🔧 From the ductwork and ventilation to the heating and cooling equipment, this was much more than a simple system replacement!
Projects like this show why HVAC planning is such an important part of a home renovation or expansion. As your living space changes, your heating and cooling needs change with it.
👏 Great work by the Sweet Pea crew!
