Most installs fall into a range based on system type (furnace vs. heat pump), size, ductwork condition, venting, electrical needs, and thermostat upgrades. The fastest way to get an exact number is an on-site visit where we size the system and confirm what needs updating.
Many standard replacements take 1 day. If we’re updating venting, making duct repairs, adding electrical work, or changing system type, it can take 2 days or more. We’ll tell you the expected timeline before scheduling so you can plan around it.
Sizing depends on square footage, insulation levels, window area, ceiling height, and layout, not just “bigger is better.” A properly sized system heats more evenly and avoids short cycling, which helps comfort and reduces wear.
Gas furnaces deliver strong, quick heat and are common where gas service is available. Heat pumps provide efficient, steady comfort and can be ducted or ductless, depending on your building. We’ll recommend what fits your space and how you use it day to day.
Not always. If ducts are crushed, leaking, undersized, or poorly routed, the new system can’t perform well, even if the equipment is great. We inspect airflow and duct condition and only recommend changes that improve comfort and performance.
