Why Upgrade Your Heating System and Ductwork?
Better Comfort
Over time, old heating systems lose their efficiency and ductwork becomes leaky. Upgrading your system restores comfort throughout the home.
Lower Utility Bills
Newer heating systems are more energy efficient, which directly translates to reduced energy costs.
Less Energy Loss
Improperly installed and leaking ductwork can waste your home’s energy. New ductwork ensures heat is delivered efficiently to the living space.
Better Air Quality
Unlike some contractors, we don’t reuse old ductwork plenums, which are often filled with dust and fiberglass insulation.
Our Heating Services
Furnace Installations
We replace old furnaces in older homes and install new furnaces in remodeling projects. Our work is always verified by a diagnostic tool that grades your furnace’s performance. We’re only satisfied when your system receives an “A.” We also pull building permits for every new installation, giving you confidence your equipment is installed correctly.
Ductwork
Your heating performance depends on the ductwork. The furnace has been lab tested, but ducting is up to the installer. As experts in sheet metal fabrication and airflow, we design and install full ductwork systems from the ground up. We do everything in-house right in Cambria, so if you need a custom-fitted component, it’s just a short drive away. We’ll cut metal, but we’ll never cut corners.
Heat Pumps
We offer mini-split installations to homeowners throughout SLO County who need air conditioning. These highly efficient HVAC systems provide both heating and cooling, so once installed, you’ll no longer need to pay for natural gas to heat your home. Whether you need a single-zone, multizone, or whole-home system, we can help.
Heating Repair and Maintenance
We service most makes and models of HVAC equipment and provide both repairs and annual tune-ups. When you have a problem, we’ll spend time with you on the phone to see if there’s a simple solution. If not, we’ll run diagnostics to find the root cause. We have no problem repairing a 10+ year old furnace even when other companies condemn it.
Accurate System Designs
Far too often, we respond to heating problems and discover that a previous contractor installed an HVAC system that’s twice as large as the home needs. This wastes energy and causes extra wear and tear, both of which are expensive for the customer.
Instead of guessing, we perform advanced calculations and tests to ensure your new furnace or heat pump is perfectly matched to your home’s heating requirements:
Manual J Load Calculations
The industry standard heating and cooling load calculation for determining the correct HVAC size in a home.
Vital Tests
Paired with the load calc, we use a tool to analyze your system’s performance vitals and ensure it’s working as efficiently as possible before we leave.
Blower Door and Ductwork Airflow Tests
For an additional fee, we can measure your home’s airtightness and ductwork airflow to get a precise load calculation.
